How does mms stand for? What is mms in a phone? Is it possible to send MMS to a phone with a monochrome display?

(MMS 2.0 standard). The operator can impose its own restrictions on the size of the transmitted message.

Principle of operation

An MMS message consists of two parts. The contents of the message are stored on a special WAP server of the operator. The second part is a special SMS message that is sent to the recipient. If the recipient's phone supports MMS, then a notification about an incoming MMS message and an offer to download the main part usually appears on the screen. If the phone does not support MMS, then most often you will receive a regular SMS message with a WAP link to the main part.

Very often, your phone has the ability to automatically download MMS messages. It is also possible to disable MMS downloads in roaming, where payment is usually charged for traffic and not for one message.

Thus, MMS is an add-on that combines SMS and WAP services. The differences lie only in the positioning of the service and in separate pricing. MMS are most often paid by the sender at a fixed price, excluding traffic, and are free for the recipient. However, when you are in roaming, traffic may be charged.

Modernity is the era of new technologies. Fifty years ago, no one could have imagined that today we would be able to send our favorite images and music to the other side of the country. Talk about your impressions not with words, but by sending a “documentary” of our life. One such opportunity is MMS. Multimedia messages achieved significant popularity with the advent of smartphones.

What is MMS

We are all familiar with text messages and use them quite regularly, but they cannot send any images or sounds. The MMS service was created specifically for this purpose. The name itself is an abbreviation that translates into Russian as “multimedia messaging service.” It seems incredible, but in the US and Norway, more than two-thirds of the total is MMS. There is a version that the technology was developed by the first providers for paid storage of photos taken from users’ phones on their servers.

The difference between MMS and SMS is that thanks to it you can send not only text, but also an image, sound, presentation or video. You can combine all this with each other or with text, provided that the resulting size does not exceed 999 kB (in some phones the size is limited to 100 kB). Almost all operators support this type of message. In order to successfully send MMS, you must have 3 and 4G protocols. This is UMTS and higher. Previously, low-speed data could be transmitted via GPRS, but today this does not seem to be a serious problem.

Packet transmission can be used for any purpose, but is usually used specifically for accessing the Internet. Because it is convenient to charge based not on time, as in a telephone conversation, but on the volume of transmitted information. Which is what is required in this case. MMS is delivered in a fundamentally different way. It was found that not every message the recipient wants to read. Therefore, to save traffic, the data is delivered to the server, from where a short request about the availability of the package comes. The shelf life usually does not exceed 3 days.

Network protocol information is transmitted at the moment when there are free voice channels formed by frequency and code methods. It is believed that the operator himself decides what type of information to give the prerogative, but if the quality of voice communication deteriorates sharply, then many will want to change the cellular operator. Be that as it may, with the introduction of smartphones, multimedia messages have become so popular that the issue of priority has had to be reconsidered in recent years: in the United States, many are dissatisfied with the service!

Not all phones support MMS because it requires some minimum capabilities. And the first of them is access to the Internet. Cheap phones can't do this because they don't have the hardware or software to do it. Physically, the phone can receive encoded information, because the transmission is on the same frequency, but it is not able to decipher and display it: there are no decoders or means of playing multimedia.

Setting up MMS

Before setting up your phone, you need to make sure that the operator cannot do it yourself. For example, MTS claims that no settings are required at all. The service is provided automatically provided that the package includes the ability to access the Internet. If MMS does not work, then you need to go here (www.mts.ru/mobil_inet_and_tv/help/settings/settings_phone/) and enter your phone number in the field by filling out the captcha.

After sending, MTS will kindly inform you whether the operation was successful. In our case, it could not be successful, since the package does not include Internet access services. This is what we were informed about. MTS is always on guard. If the settings do not want to be applied or saved, then you need to adjust the data manually. To do this, the provider provides point by point:

1. Internet.

Let’s quickly move on to the last section to see what interesting things they will say there. The window that opens offers (very competently) the following sub-items:

1. iOS for the new sixth generation iPhone.
2. Other gadgets from Apple.
3. Devices with the Android operating system.
4. Windows phones.
5. Other non-smartphone devices.

Regular phone

Shown is an old phone with CSD technology, which was later replaced by GPRS. Therefore, settings are carried out taking into account this archaic feature. In the menu you need to enable the use of GPRS, because by default there will be an attempt to transfer data without packets via CSD.

Then we proceed to setting the IP address 192.168.192.192 and the transmission port 9201.

It's time to enter the MMS server address.

MTS has already created our profile for us, all that remains is to activate it.

And yet we check whether the settings have changed over the past 10 years.

No, everything remains the same. Login: mts, and password is the same. To activate the service, we send a trial MMS to the toll-free number 8890.

Trying to set up Android

Under Android operating systems, you need to go to settings and find Wireless Networks there. Since any communication is via the air, this is the only option for a smartphone.

The ultimate goal is to find the Access Points subsection. Let's create a new one.

We enter the access point settings according to the list, if necessary, specify the MMS WAP 2.0 transmission protocol.

After this, you need to send an MMS to the toll-free number 8890.

Sending MMS

Service packages

In a typical case, setting up MMS occurs through a request for a short or regular number (see above). Several services are connected at the same time. MMS from a mobile operator goes side by side with 3/4G Internet. If you don’t understand, you can call the support service or use the hotline - they will help you. If your device supports two SIM cards, take your time to activate the service, study the tariffs and choose the most profitable one for your level of use. Next, let's look at how to set up MMS on your phone.

The next steps will depend on what brand of phone you have. We will look at the iOS and Android platforms.

MMS for Apple

Let's take a step-by-step look at what you need to do with your phone so that your multimedia messaging service will work.

1. The first thing you need to do is go to the home menu and go to “Settings”.
2. In the menu that opens, select the “Basic” sub-item.
3. The next inscription you need to click on is “Network”.
4. Next, “Cellular data network.”
5. Having reached this point, you will need internet from another resource. Here you need to enter the operator settings. You can find them either simply on the Internet, or by accessing information from the official website, which, of course, is preferable. The fact is that they are sometimes changed, and the operator’s resource has the latest data.
6. After you have entered all the necessary information, you must restart the device.
7. The next step is to add your SIM card number. Again you need to go to the “Settings” settings and select the “Phone” sub-item.
8. In the “My number” field, you need to enter the number of the SIM card through which you connected the mobile Internet service.
9. In order for the multimedia data service to work, you need to restart your phone again.

These 9 points will help you enable the MMS transfer function. If you have completed everything, but the Internet does not work, check everything again, starting from the first point. If everything is correct and the connection is still not established, try to find other data to fill out the operator settings. Even if this fails, do not despair and call support.

Introduction

One of the newest developments in mobile messaging is Multimedia Messaging Service (MMS). Like a regular short messaging service (SMS), it provides automatic and instant delivery of personalized messages. But unlike SMS, it allows mobile phone users to include sound and images in messages, turning them into visual audio messages.

Using MMS, you can send multimedia messages not only from one phone to another, but also from phone to email. This feature significantly increases the possibilities of mobile communication for private and corporate users. MMS covers a wide range of different types of content and is a logical complement to SMS, making it easy to learn for the current generation of mobile phone users. The advantage of MMS is that messages are a single multimedia presentation, rather than just text with separate media attachments.

MMS works with JPEG, GIF, AMR Voice and other formats. Like SMS, it is an open industry standard, and MMS messages can be transmitted using existing networks and protocols. In addition, MMS is independent of network transport, and its use is not limited to GSM or WCDMA networks. Although the transmission speed of MMS messages is high, it still depends on the size of the message itself and the type of transport used. In any case, the recipient only knows that the message has been received when it has already been fully received. This makes using MMS as easy and convenient as using SMS.

Evolution of MMS

Multimedia Messaging Service (MMS), which stemmed from the overwhelming success of Short Messaging Service (SMS), has moved well beyond the ability to send simple text. According to statistics, at the end of 2002 the monthly volume of SMS messages sent was about 100 million. It is likely that MMS will develop just as rapidly, and its use will benefit from the transition to 2.5G and 3G technologies. Nokia believes that MMS will quickly become a truly mainstream technology for both personal and corporate use. The types of services used for business and personal purposes are not fundamentally different from each other. This means that MMS technology can meet the needs of a wide range of users. Phone owners will find that learning how to use MMS is easy since it is simply a modified form of SMS. Thus, MMS allows us to take a step forward - towards 3G communications services. Although the number of MMS-enabled mobile phones is expected to grow rapidly, phones without this feature will continue to be manufactured by Nokia.

Benefits of MMS

Multimedia messaging (MMS) can be used to both distribute public content and exchange personal information, providing phone owners with a rich communication channel and allowing operators and providers to increase profits. Nokia hopes that MMS will help stimulate the development of GPRS technology and data services, as well as encourage developers of MMS content. As with SMS, the value chain for MMS is relatively short: content is created both by users themselves or third-party content providers, and by store-and-send services provided by the operator. The MMS business model will be an extension of the successful SMS business model, with high profitability for all parts of the value chain.

Benefits for users

Mobile messaging is extremely popular and occupies a vital place among modern communication methods. It's fast, personalized and location independent. This is why mobile phone owners prefer to use multimedia messaging, making it one of the fastest growing segments in the mobile communications industry. In addition, the scalable MMS technology is suitable for all types of mobile phones, and its compatibility with email gives greater freedom in choosing recipients.

Benefits for telecom operators

MMS allows for the natural evolution of messaging services and the emergence of new services. This leads to an increase in airtime, high differentiation of services and increased subscriber loyalty. Flexibility in payment methods and the ability to offer great value for messaging also promises increased profits.

Benefits for Content Providers

Since MMS is independent of transport type, it provides a foothold for investments in GPRS and WCDMA, providing them with applications aimed at the mass market and optimizing infrastructure utilization. Early adopters of MMS will be able to secure a strong market position and gain critical leadership experience in personal multimedia communications to compete.

Questions and answers

What is Multimedia Messaging Service (MMS)?

MMS is a mobile messaging service standardized by the WAP Forum and the 3D Generation Partnership Program (3GPP). MMS is very similar to short messaging service (SMS). It provides instant automatic sending of user-created messages from phone to phone. But for SMS, the phone number is specified as the address, and MMS allows you to also specify an email address. Therefore, messages can be sent from phone to email and vice versa. In addition to the usual SMS text content, MMS can contain photos, video and audio clips. Another advantage of MMS is that the message is a multimedia presentation, rather than just text with attachments. In addition, MMS does not depend on the type of transport and is not limited to GSM and WCDMA networks.

Is MMS a WAP application?

MMS does not use a WAP browser. MMS is a messaging application, not a browser. This technology uses its own user interface (just like SMS).

Is MMS a Nokia proprietary service or is it a standardized service?

The WAP Forum and 3GPP have certified MMS as an open standard. The 3GPP specification defines the network architecture and general functionality. The WAP Forum specification defines the message format and application protocols. Existing protocols are used to deliver messages.

Does MMS require network changes?

MMS is primarily used as a means of exchanging messages between phones. There is always the possibility that a message cannot be delivered because the recipient's phone is turned off, has a low battery, or is out of coverage. A new network element, the MMS service center (MMSC), is needed to store undelivered MMS messages until the recipient's phone is reachable. In addition, MMSC has many interfaces for connecting to networks, as well as APIs to provide additional services and network interaction with email. Nokia and some other vendors produce MMSC.

What types of content does MMS support?

The MMS standard does not specify any content formats. Instead, MMS encapsulates content in messages in a standard way, and the receiving party can identify the content formats and work with those that it supports. The same solution is used to work with various types of content on the Internet. Despite this, the standard recommends implementing support for JPEG, GIF, text, AMR Voice, H263 and other formats. To achieve compatibility, Nokia and some other manufacturers have entered into an agreement called the MMS Conformance Document, which describes the minimum set of data formats supported by an MMS phone.

How big can an MMS message be?

The standard does not define the maximum size of an MMS message. This is to ensure future scalability of the technology and to avoid the problem encountered with SMS, where the maximum length of 160 characters was not sufficient. Therefore, the maximum message size depends on the specific MMS implementation. It also depends on the preferences of the operator, who may set a fixed message size for the convenience of his own billing system. Nokia believes that initially the message size will range from 30 to 100 kilobytes.

How fast is the transfer of MMS messages?

The transmission speed of MMS messages depends on the size of the message and the type of transport used. But since the recipient receives notification of the arrival of a new message only when it is completely delivered, he does not experience any delay in any case.

Can I send MMS to a phone that does not support MMS messaging?

Nokia MMS solutions provide support for phones that do not have MMS functionality. If the recipient's phone is determined to be unable to work with MMS, the message is saved on a web page, and an SMS message is sent to the recipient indicating the address of this page.

Can I send MMS to phones equipped with monochrome displays?

A significant part of MMS content consists of color images. To fully enjoy the MMS experience, a color display is required. But, in theory, any phone equipped with an MMS function can receive MMS messages. There are several ways to display color images on black-and-white displays, and you can get a limited understanding of a color image by viewing it on a black-and-white display.

Articles and Lifehacks

Multimedia messages in cellular networks allow subscribers to exchange photos, videos and music with each other. However, not every user knows what is the maximum size of an MMS message? he can send or receive.

It should be noted that volume limitations, as in the case, depend on the standard used. In addition, there is a dependence on the specific mobile device and the own restrictions of a particular operator.

How MMS messages work and their maximum size

So, MMS are multimedia messages that support voice recordings, audio, graphics, video, animation, etc. In our mobile device, such messages look like slides. You can also attach audio to them. In addition, we will be able to send various graphics, videos and regular animations. If our device supports MMS, we will also be able to receive multimedia messages from other subscribers.
It is quite convenient to send to other users photographs just taken using the camera of the mobile device itself, or sounds recorded on a voice recorder. You can add accompanying text to all this.

Essentially, MMS are a special type of message. Data is transmitted in 2 parts - the information itself, as well as the header.

Messages are stored on the wap server

If your mobile device does not support MMS, we will only receive an SMS message with a link. It is best to view the sent MMS by entering the sent link into the browser of a computer with Internet access.
So what is the maximum MMS message size? Sometimes restrictions can be set by the mobile device itself - for example, no more than 100 kilobytes.

Let's also consider the dependence of the MMS size on various operators and specific mobile devices.

Maximum sizes of MMS messages of various operators

Theoretically, the size of such messages is unlimited, but in reality everything is different. Most mobile devices produced by various companies support sending MMS up to 30 kilobytes, while most operators support up to 300 kilobytes. The last figure corresponds to the size of several photos, or the size of a video no more than 40 seconds long. So, it’s worth taking this point into account.

Sometimes users change the firmware on their mobile device, which allows them to increase the maximum MMS volume, or use special patches, risking harm to their phone. Many mobile operators independently set limits on the size of MMS messages. For example, MTS users can send MMS no more than 500 kilobytes.

Simple but effective ideas “shoot” much more powerfully than complex, confusing concepts. This has been known for a long time. Therefore, you should not be surprised that a simple, sometimes even scanty service called SMS has gained such popularity.

But people involved in mobile technologies have already prepared a replacement for the good old SMS. Yes, you guessed it. We are talking about MMS.

The abbreviation MMS stands for Multimedia Messaging Service. Unlike SMS with its significant restrictions on the size and type of information transmitted, MMS technology allows you to instantly transfer not only text, but also other multimedia content: photographs (which you can take within a few seconds using the camera built into the device), music, voice recordings, videos... The list goes on.

According to the description of the MMS standard, there are no strictly defined data formats for transmitted attachments. Moreover, the receiving device must be able to process any type of attachment. Now manufacturers are trying to adhere to the pre-agreed “MMS Agreement” so that in the future there will be no problems with the compatibility of multimedia messages, but it is quite possible that this document will be changed and supplemented.

As already mentioned, there are no official restrictions on the size of MMS messages sent. However, in reality, each cellular operator introduces its own limits on the amount of information sent in order to more accurately calculate the cost of the service provided.

One of the positive properties of multimedia messages is the compatibility already mentioned above. The owner of a Siemens phone can send a picture to his friend's Nokia and be sure that the recipient will receive exactly what was sent.

Wheels and gears

Even if you don’t know whether the recipient’s device supports MMS, you can still safely send him a message, and it will not be lost or erased, and the recipient will be able to read the message, even if his phone model is not equipped with an application for working with messages of this type .

The thing is that MMS transmission is managed not by one service center, as was the case with SMS, but by a whole complex. The brain of this system is MMS Relay - a message switching server. It receives, processes and forwards all multimedia messages from a specific operator, communicates with MMS centers of other operators, and also allows you to work with MMS not only from the screen of a mobile phone. Auxiliary components are, first of all, a WAP gateway, which is responsible for delivering the multimedia component of the message, a database server in which messages are stored for some time, as well as the already familiar SMS center, which manages the delivery of reports and service information to subscribers’ phones . Thanks to such a complex system, the end user has a wide range of possibilities for working with multimedia messages.

* We can send MMS from a mobile phone to e-mail, and the recipient will receive the message as a regular e-mail.

* Using special MMS mail gates, we can send an e-mail that will be sent to your cell phone as a multimedia message.

* It doesn’t matter what phone model the recipient has: the system itself will figure out in what form to display the information. First, the MMS center will send a system SMS with service data to the phone, and then either send a text message with a link to your message (if the device does not support MMS), or use WAP to connect to the server and download the message to the phone. By the way, you don’t have to worry about traffic - incoming MMS from our operators is free.

Motivation

The functionality of MMS is much wider than it might even seem at first glance. The opportunities available to the user can be divided into four groups.

1. The actual exchange of messages. If you want to convey information that does not want to fit into not just one, but three SMS, use a multimedia message.

Note to schoolchildren and students: this thing is great for passing on cheat sheets.

Want to congratulate someone with a small message, but don't want it to sound dull? Attach a nice picture to the MMS, and maybe even a voice recording of your congratulations.

All this will be displayed on the recipient’s screen in the form of a Power Point presentation: first the illustration will appear, then the text, and finally the recorded message will be played. Such a virtual one will leave few people indifferent!

Made an appointment in an unfamiliar place? Found a street, but can't find a house (perhaps because a sign or sign has fallen off)? Ask them to send you a picture of the meeting place, and thanks to the picture you will instantly find the building you need.

Or, for example, your friend needs to meet with another person, but only you know his face. And in this situation it is difficult to come up with something simpler than sending a photo of the desired person via MMS.

2. Information services based on MMS. This is a worthy alternative to similar SMS services, as well as WAP pages. The most obvious advantage of multimedia messages is the much richer possibilities for designing information messages. But there is something more. For example, MMS can be integrated with a subscriber location system, and then the user, having sent a request with the address he needs, will receive a map in response indicating the optimal route.

3. Business services. MMS seriously expands the range of services for business people. For example, a subscriber can receive on his device not only the latest stock market reports, but also graphs or diagrams of their changes for an arbitrarily selected time interval.

4. Entertainment. British analysts estimate that more than 70% of MMS messages in the UK contain sports or erotic content. In addition, the mobile operator, together with third-party content providers, can offer its subscribers such services as: MMS chat, MMS games, MMS dating, etc.

Also, do not forget that special server applications are created on the basis of MMS, facilitating more convenient and faster access to content. These are a multimedia box (MMBox) and a multimedia album (MMS Album).

Multimedia box

If a subscriber actively uses MMS services, then sooner or later he will need to store his messages somewhere. It’s not possible to keep them all in the phone’s memory!

To solve this problem, the operator creates a separate database called a “multimedia box”. In this database, the subscriber can store his messages for an arbitrary period of time. In addition, the subscriber can generate and send multimedia messages without first downloading the necessary content to the device. To do this, it sends a control message to the MMS center containing information about the recipient and the necessary attachments, which the MMS center automatically picks up from the subscriber’s multimedia box. The subscriber can also access his messages via WAP or the Internet.

Multimedia album

To fill an MMS message with the necessary content, the operator creates a content database called a “multimedia album.” This database is located on a separate server and contains audio and video fragments, pictures, logos, which the subscriber can freely download to create an MMS.

Workshop

But in terms of ease of setup, MMS is a little inferior to SMS. Here it will not be enough to simply enter the number of the message processing center (which is often already stored in the SIM card).

So, MMS are transmitted via WAP. There are two types of WAP connection:

* CSD (direct call to the mobile operator pool; data transfer speed leaves much to be desired);

* GPRS. In fair competition, the second option won by knockout long ago, so we won’t even consider CSD. This is too dark a thing. Below are instructions for three major Moscow GSM operators, while information on others can be found in their sales offices or on official websites.

"Beeline"

You can connect GPRS-WAP and MMS (the so-called “Package of three services”) in two ways:

1. Call 06709181.

2. Dial the command *101*181# on your phone.

After connecting the “Pack of three services”, the device must be rebooted.

Next you need to configure the phone itself. Order settings for GPRS-WAP and MMS on the official Beeline website or at the subscriber service. After they arrive to you by service SMS, save them and reboot your phone to register in the MMS system. Finally, send an MMS with any symbol to number 000 and wait for a message confirming the final activation of the service.

To disable this package, you must call 067409180.

You can activate the GPRS service in the following ways: by coming in person to any of the sales and service offices; directly from a mobile or landline phone through the ACCA system (to do this, dial 08802449, and then press 1 to confirm adding the service), or through the ACCA Internet service.

"Megaphone"

This operator has the easiest setup option.

If you use a contract tariff, then the GPRS service is already activated, and users of LITE tariffs just need to dial the special command *105*4*4*2#.

After that, order free settings specifically for your phone model from the website or through the subscriber service, and then activate MMS services using the Service Guide or dial *105# and follow the instructions on the phone screen.

The easiest way to find out prices is individually, although we note that in most cases the cost of one multimedia message fluctuates around 20 cents (6-7 rubles).

The maximum volume of MMS is also set by the mobile operator. Most often, users are allowed to send messages no more than 100 kb, although during some promotions the bar can rise sharply to 512 kb. Another thing is that some mobile devices with MMS support have an internal limit on the size of messages, which for one reason or another is less than that set by the cellular operator. In such cases, either changing the phone’s firmware to a more recent one, where perhaps this problem has already been solved, or installing (at your own peril and risk) unofficial patches can come to the rescue.
