Gansu Mobile received a message saying that "the sent MMS is not included or the format is incorrect". What happened?

The sent multimedia message does not contain pictures or the picture format is wrong, indicating that the multimedia message may only have text parts, or the multimedia message does not meet the requirements, which is reflected in two aspects:

The file format of MMS does not match. MMS can include information in various multimedia formats, such as text, images, sounds and data. Take pictures as an example. Both regular JPG format and gif format are acceptable. If PSD format is used, it cannot be sent.

The size of MMS file exceeds the standard. In order to ensure the success rate of sending MMS, the size of each MMS in China Mobile MMS service is about 50 kilobytes. If the picture or sound file exceeds 50 kilobytes, it cannot be sent.
