Why is the mms not loaded on the phone. Why does my smartphone not accept mms. How to set up an Android gadget to send MMS. Configuring MMS on MTS

In order to send someone a sound file, photo or video, it is not necessary to use e-mail - it is enough to use the MMS sending service. This service is used by a limited number of subscribers, but sometimes it is the only way to deliver multimedia information. For example, sending MMS is useful if the recipient does not have any tools for communicating with the outside world, except for a simple phone with MMS support. How to send MMS from MTS, how to set up your phone to receive multimedia messages, how to send a message for free - our review will tell you everything.

In order to connect MMS to MTS, you do not need to take any action - in most cases this service is activated by default... If for some reason this is not the case, you should look into your Personal Account and connect the Mobile Internet service there (MMS works through data transfer services). If there is no Internet access, the service can be activated using the USSD command * 111 * 18 # or by sending an SMS with the text 2122 to the short service number 111.

There are no subscription fees and fees for connecting to the "Mobile Internet" service. After that, you can set up your mobile phone and start messaging. The cost of sending MMS to MTS depends on the subscriber's tariff plan. To reduce the cost of MMS-exchange, an MMS package of 10 messages is provided for 35 rubles for 30 days.

How to set up MMS on MTS

In order to receive and send MMS messages, the subscriber needs a configured phone. Most often settings are set automatically, immediately after inserting a SIM card into the phone. If this is not the case, you need order automatic settings by sending an empty SMS to the service number 1234(or call the toll free number 0876). After saving the settings and restarting the phone, you need to send a test MMS to 8890 (free of charge) - the network will understand that the phone is set up and can normally receive multimedia messages.

Otherwise, all received messages will be sent to the MMS-portal of MTS, and the recipient will receive SMS-notifications with links to view MMS on the portal. If the automatic settings for some reason do not come or are not installed, you should register them manually. How to do this depends on the specific phone model. The subscriber should go to the Internet access settings section and create there profile with the following parameters(sometimes the MMS profile setting can be found in the MMS settings section):

  • Profile name - MMS MTS (or something else);
  • Home page - http: // mmsc;
  • Data channel - GPRS;
  • Access point - mms.mts.ru (without http: //);
  • IP address (proxy address) - 192.168.192.192;
  • Proxy port - 9201 for old phones, 8080 for new phones;
  • Username and password - mts.

The parameter names may differ depending on the phone model. The parameters not specified in the overview should be left as they are. After entering the parameters, select the specified profile in the MMS settings, reboot and send a test MMS to the service number 8890.

How to send MMS to MTS from your phone

To send MMS from your mobile phone, need to go to the section with messages and select the item for sending messages there(“Send MMS” or just “Send message”, “New message”, etc., depending on the device model). Add the necessary files to the message. The maximum size of MMS is 300 kb, and phones that are too large can be scaled to the required size on their own.

Next, select the recipient or enter his number manually, and then press the send button - after a few seconds (depending on the connection speed) MMS will be sent to the recipient. The recipient's number must start with +7- this is a prerequisite for sending MMS messages.

How to send MMS to MTS for free

Send MMS to MTS will help you for free official website of MTS- there is a corresponding form for this. We fill in the recipient and sender numbers, enter the title and text of the message (up to 1000 characters), add files or select a picture from the proposed gallery, and then click on the send button. The sender's phone number is indicated to protect recipients from MMS spam - a confirmation SMS will be sent to the specified number. In addition, in the form of sending MMS, you will need to go through additional antispam. Service limitations:

  • Message size - no more than 300 Kb;
  • Text size - no more than 1000 characters;
  • Sending MMS from one IP - 1 MMS from 1 IP in two minutes;
  • Sending MMS to the same number - once every 2 minutes.

If the MMS recipient has the service “Prohibition of receiving informational SMS and SMS / MMS from the MTS website” activated, the message will not reach such recipient.

How to watch MMS on MTS

In order to view the MMS content, you need to extract it by clicking on the corresponding menu item. If the phone is configured to automatically receive MMS, then you just need to open the delivered message... If the recipient's phone is unable to receive MMS, then the messages will be available from the pages of the MMS-portal, as already mentioned in our review - follow the link indicated in the SMS-notification, enter the password and view the contents of the received message.

Setting up MMS on Android may be required in two cases. The first one is buying a new smartphone. The second is to reset existing parameters to factory defaults. In any case, you need to change the configuration so that this service works. This can be done in four ways:

  • Automatically.
  • With the help of a service center operator.
  • By manually entering the required values.
  • Using the operator's regional website.

It is all these methods that will be discussed in detail within the framework of this material.

Automatic tuning

Automatic configuration of MMS on Android takes place with minimal human participation - this is its main advantage. But the disadvantage is that it can be done only once - during the initial registration of the device in the operator's network mobile communications... After that, it is considered that everything is configured and there is no need to re-send this data. Its order is as follows:

  • We install the SIM card into the corresponding slot of the smartphone and assemble it.
  • We turn on the device and, if necessary, enter the PIN code.
  • As soon as the registration is completed, the search for the required values ​​begins in the operator's database. After they are found, this information is sent to the gadget.
  • Then the subscriber must accept the configuration profile and save it.

This completes the automatic configuration process. But the very process of receiving and sending messages can be blocked. The activation procedure will be described later in the text.

Operator assistance

Unlike automatic, setting up MMS on Android with the help of a service center operator or by manual input can be done many times - this is their plus. But on the other hand, in the process of their execution, you need to perform certain manipulations, which slightly complicates the configuration process. Each of the operators has a free consultation number. For Beeline it is 0611, for MTS - 0890, for Megafon - 0550. Then, following the instructions of the autoinformer, you need to establish a connection with the operator and order the necessary settings, which will then be sent to your smartphone. Then they need to be accepted and saved. After this operation, it is recommended to do a complete reboot of the device, that is, turn it off and on. In some cases, you may need to activate the service. To do this, during a call to the operator, please enable this service for this number. This completes the MMC setup on Android with the help of the service center operator.

Manual input

It is not always possible to call the service center, but the MMS must be urgently received. In this case, the necessary settings can be set manually. To do this, go to the following address: "Applications" \ "Settings" \ "Networks" \ "More" \ "Mobile networks" \ "APN". Then you need to enter the operator's parameters - this is the actual manual setting of MMS on Android. Beeline, for example, requires the following parameters:

  • Profile name must be Beeline MMS.
  • The home page in this case is http: // mms /.
  • Data transmission channel - GPRS.
  • Access point - mms.beeline.ru.
  • The IP address is 192.168.094.023.
  • and the password is the same - beeline.

The rest of the values ​​remain unchanged. For MTS, you need to enter the following data:

  • Profile name - MTS Center MMC.
  • APN must be mms.mts.ru.
  • Login and password in this case are identical - mts.
  • Home page - http: // mmsc.
  • The IP address is 192.168.192.192.

As in the previous case, we leave all other values ​​unchanged. Setting up MMS Megaphone on Android requires the following values:

  • The profile name is megafon.
  • APN depends on the tariff plan. Here you need to look at the documentation that came with the starter package.
  • Login and password in this case are identical - gdata.
  • Home page - http: // mmsc: 8002.
  • IP address - 10.10.10.10.
  • Port - 8080 (9201 can be used on some models).

We do not touch the rest and leave it as it is.


Another way ...

Another way to get the settings is to order them on the operator's regional website. To do this, on a computer connected to the Internet, through a search engine, we find the page we need. Then we select the smartphone model and enter the captcha and mobile number. Then we press "Send". The necessary information will be received within 5 minutes. We save and install the required profiles. If the requested information has not been received within 5 minutes, then it is better to repeat the order on the same regional website of the mobile operator. It is also recommended to do a full reboot of the phone. After that, we send and receive MMS. There shouldn't be any problems. If something doesn't work, we look for an error. As practice shows, they did something wrong somewhere. You can delete the old profile and do everything again.


Outcomes

In this article, it was described in stages what is on Android for various operators. As you can see from everything that was said earlier, there is nothing complicated about this. The happy owner of a new smartphone can cope with such a task without any problems. You just need to follow all the instructions, and you should not have any problems with this procedure.

Today, to send media files, users generally prefer to choose e-mail or social networks, for example, Odnoklassniki, Vkontakte and others. But, in principle, there are still people of the old school who still want to work with MMS rather than with e-mail. Why, you ask? There are hundreds of responses: e-mail can be hacked, mailboxes are difficult to register for individuals, it is very difficult to remember your address than someone else's, you constantly forget your password, and much more. In this case, we decided to describe in detail how to set up MMS on your Android and what is needed for this!

In principle, the setup process is no different from the devices of the previous generation, when we registered all the settings in manual or automatic mode. We will describe all the methods for the major cellular operators.

The article will contain the following operators:

  • Beeline;
  • Megaphone;
  • Tele 2.

Initially, you need to check if the service is connected at all for your number or not, because in some regions, oddly enough, it is disabled for certain numbers. Call in service center customer support of your operator. All calls are free!

Generally, the easiest way is to call the same service center and ask the operator to send you the settings... In this case, all operations will be carried out automatically, and for MMS to work correctly, you will only need to reboot the device and use this technology to the fullest.

Usually the phone model is named to the operator, after which the settings are sent and saved automatically. But it often happens that the user needs to do everything himself in manual mode.

For Megaphone

If you have a SIM card from Megafon, then you will need to use the instructions described in this subheading!

Automatic tuning. Send a free text message to 5049. In a few minutes, a message with the necessary parameters specifically for your model will be sent to your number in automatic mode. You need to save them and restart your phone. Then you can try sending MMS to your friends.

Manual setting. In the Android operating system, go to the "Settings" item, select the "Wireless networks" tab and then "Mobile network". Here you will need to click on the "Access Points" tab. Now carefully review what data must be filled in!

Please note that all submitted data must be filled in exactly as described above. Each entry is registered in a separate tab. You will see all these fields when you go to the menu in the item "Access points". Then you just have to click the "Save" button, restart your phone and check the MMS functionality.

For Beeline

If you use a SIM card from Beeline, then you need to configure MMS, based on the instructions in this subheading!

Automatic. Call the free number 06741015, after which all MMS parameters will be automatically sent to you. They can be saved directly in the dialog menu after opening an incoming SMS. Beeline also has an option to configure this technology using personal account.

Manual. Go to "Settings", select the tab " Wireless networks"And go to the" Mobile network ", click the item" Access points ". Here you will need to specify the settings specifically for Beeline! They will be as follows:


For MTS

If you are using an MTS SIM card, then you need to perform the settings according to the instructions in this subheading.

Automatic. It is necessary to send an SMS message with empty content to the service number 1234, after which, within a few minutes, the subscriber will receive a reply SMS from the operator with the settings for his device. You need to save them and restart your phone, after which you can send MMS. It is also possible to configure MMS using the "Internet Assistant", where each user independently controls the options on his phone.

Manual. For manual configuration, you need to go to "Settings", then to "Wireless networks". Select "Mobile network" - "Access points" and write down the settings described below:


Save all the registered parameters and reboot your phone.

For Tele 2

Despite the fact that Tele 2 has existed not so long ago, you can also configure MMS for it, both on a regular device with support for Java applications, and on modern devices with Android and iOS.

Manual setting. Go to the "Settings" menu item, then select "Wireless networks" and click "Mobile network". Go to the "Access Points" tab and set the following parameters:


conclusions

In general, we can conclude that setting up MMC on Android is not difficult, regardless of which operator you use. Just keep in mind that sending one MMS costs about 7 rubles, and this is not very profitable, given the capabilities of modern technologies that allow you to send high-quality media files for free.

In the Android operating system, do not forget to activate the mobile network, because it can be turned off by default! Attention! If you do not activate the mobile network, sending MMS will not be possible. To do this, go to the main menu "Settings" and select the item "Wireless networks". Click on the "Mobile Network" tab and activate it.

Also in OS Android, on the quick tabs bar, you can enable data transfer with one click.

What is setting mms on android? Today, such a service is no longer something new, but it continues to be one of the most convenient, given that you can transfer various files via MMS, including photos and images. Many users specifically choose those cellular operators that provide packaged MMS messages. For example, the MTS company offers its subscribers packages for 10.20 or 50 messages, the MMS + service (messages with a discount), as well as special tariff plans with unlimited MMS messages. There's even a free MMS Show! And how to set up mms on android without the help of specialists.

Preparing MMS settings for Android

The reasons for the incorrect operation of MMS are, as always, commonplace (but these are definitely not problems with registering an iPhone, which Apple often has). And the first is the absence of such settings on the device at all. This means they must be ordered from your mobile operator. After they are sent to your phone, you need to save them.

Smartphones of the new generation, upon first launch, together with a SIM card, themselves identify the Internet and MMS settings. However, this only applies to those SIM cards that already contain such information.

How to set up MMS yourself? For this function to work correctly, after saving the settings, the mobile device must create 2 points, having received data via a GSM network or from a SIM card - a point for transmitting MMS messages and an Internet access point. If the SIM card is already many years old, it is unlikely that the phone will be able to independently identify itself in the network of the cellular operator. How to be in this case?

Instructions for setting up MMS on Android

How does setting up mms on android begin? First, you should go to the "Settings" of the mobile device, the item "More". In different phone models, the item may be called differently - for example, "Communication settings" or analogs of such a phrase. Next, select the "Mobile network" option and click on it, after which the user will see the settings that are associated with his cellular operator.

The next item he needs is "Access points" ("Access points", "APN", etc.) Here you will need to create a new access point specifically for MMS. To do this, click on the auxiliary menu and select "New access point" ("Create APN"). Most likely, there will be no access point, but if it already exists, but MMS messages are still not sent, you will need to delete it and create a new one.

For a new access point, you need a certain list of parameters, which you can find out from your mobile operator. For example, for Beeline subscribers, they look like this: MMSC - http: // mms /, Proxy -192.168.094.023: 8080, APN - mms.beeline.ru, Username - beeline, Password - beeline. So, it remains to enter the correct parameters.

Video: Internet and MMS settings for Android phones

MMS messages have been known to us since the advent of color telephones, thanks to which mobile communication has opened up great opportunities for us. But a few years later, technical progress gave us more advanced technologies that pushed MMS messages into the background. Although, we cannot completely forget about this type of information transfer, since such situations happen in life, then it is necessary to use MMS and in this article we will consider the question: how to send mms on android and how to set up your device correctly. And those who often use this type of message specifically choose mobile operators that have batch messages. For example, MTS is a very popular operator that works with this message format.

Preparing the setup

MMS messages may not work for you for quite simple reasons that seem ridiculous at first glance. You need to look at the settings first, as they are often not there at all. If they are absent, you need to make a request to your operator to receive these settings. As a rule, after a request, the settings will come within a few minutes, and you just have to save them.


Since modern smartphones have many functions, the first time you start with an inserted SIM card, the settings will be saved by themselves. It is worth remembering, however, that this feature will only work with themes for SIM cards that have already received these settings.

After receiving the settings from the operator or reading them from the SIM card, your smartphone must return two access points, it receives these points from the SIM card or GMS network. Many smartphones have old SIM-cards, which, due to their increased size, do not allow the smartphone to read the necessary information. This case is very difficult, but not worth saddening, as everything can be resolved in a few minutes.

Setting up MMS on Android devices

First you need to go to the "Settings" of your smartphone running OS Android, then find the item "More". But this item may have another name, since there are a huge number of Android phone models in the world. After selecting this item, go to the "Mobile network" option, in it, you will see all the settings that are associated with your mobile operator.

Then we go to the item "Access points", at this point we will need to create a special access point for MMC. To create such an access point, you need to call the "New access point" command. If the access point for sending MMS already exists, but it does not work, you need to delete it.

And now to the most difficult part, to create a new access point you need a list of special parameters that are different for each operator. You are provided with an example parameter for subscribers Beeline MMSC - http: // mms /, Proxy -192.168.094.023: 8080, APN - mms.beeline.ru, Username - beeline, Password - beeline.

It's time to tell how to set up MMS on android smartphones.

So, as always, the instructions are broken down into simple and straightforward steps. But before that, it is necessary to explain to our reader why MMS does not work on his phone. The reasons, as always, are pretty commonplace. Nevertheless, if the instructions do not help, you will always understand the essence of the problem.

Modern smartphones, when first launched with a SIM card, themselves determine the settings of the mobile Internet and MMS. However, this only happens with new sim cards that already contain such information.

In such a situation, the phone must create two points by taking them from a sim card or receiving data via the GSM network:

  1. Internet access point
  2. MMS messaging points

If your SIM card is many years old, it is highly likely that the phone will not be able to "self-identify" in the operator's network. What then is to be done? This is what we will tell you, so how:

Step 1. We go to the phone settings. We are interested in the item "More" v new Android ICS. Or "Communication settings", as well as analogues of this phrase.

Step 4. Click on the auxiliary menu and select "New access point"... In this example, the MMS point has already been created, so do not look at it. In your case, most likely the point will be absent. If it is present, but MMS is not sent, then delete the existing point and create a new one.

Step 5. Well, this is the list of parameters that we will need to enter for a new point, and then save it. To find out parameters of your operator, see below.

Cellular operator options for setting up MMS

These parameters are indicated only for the Moscow region and the Moscow region. Note that in the case of Beeline and Megafon, indicated only differing data... Therefore, for Beeline and Megafon subscribers: first look at the MTS data, and only then the additions to your operator.
