You sent an MMS, but the message did not come. Guilty of this may be your phone, and the receiver's device, and the communication operator.
It is only necessary to find out which of the links in the chain has failed and try to eliminate the cause.
The MMS sending and receiving service isMost subscribers by default. An exception can only be made by customers who have been connected for a long time, when MMS did not exist yet, and since then they have never changed a SIM card or tariff plan. If you are one, contact your operator's support desk and ask if you have this service turned on. If not, order its inclusion. Perhaps you will be informed that the service subscription service via the support service is chargeable, in such case, ask to dictate or send by SMS a USSD-command for self-activation of the service, and then dial it.
MMS may not be set up on your machine orThe receiver. First of all, you should make sure that there is such a function in both phones. By the way, their appearance about the presence of this function does not say anything. For example, the Siemens C55 phone with a monochrome screen and built-in memory of less than one megabyte supports MMS (although you can only send and receive audio files, as well as black and white images of the old WBMP format), and Texet TM-B112, despite the color display and Built-in MP3 player with Micro SD card, MMS function is not equipped.
If the MMS function is present but not configured, you need toAgain contact the operator's support service and ask to send an MMS configuration message indicating the model of the device. When the message arrives, open it and select the menu item to save the settings.
The format of the file sent by you shouldSupported by the recipient's phone. It is clear that sending a JPG file to the same Siemens C55 is useless. Moreover, this format is supported not even by all the early phones with color screens. Also important is the amount of file being transferred.
The standard for MMS provides a total volumeAll files in one message are not more than 300 kilobytes. But additional restrictions can be set by the sender's and receiver's devices, as well as by the operator, especially when the unlimited MMS service is activated. It often helps to reduce the amount of messages to 150 or less kilobytes.
There are also restrictions on the MMS jigging betweenOperators, cities and countries. On major holidays, MMS-messages sent at an unlimited tariff may not reach, or they can still be charged. Some operators also do not support sending MMS to e-mail.
All days of MMS-messages sent byUnlimited tariffs, can come with a considerable delay, sometimes several hours. It should also be noted that if you use unlimited Internet on your mobile phone, you can send files in most cases more efficiently through it, and not via MMS.
