What if the SMS function suddenly disappears?

How to deal with the lack of SMS function in mobile phones;

The short message function on the mobile phone suddenly disappeared because the mobile phone short message system failed, and the factory settings were restored to restart the mobile phone.

If it can't be solved, it is recommended to go to a professional maintenance firm for professional maintenance.

Supported by mobile phones? Short message protocol, namely multimedia protocol, mainly includes SMS, EMS and MMS at present.

EMS (enhanced short message service) means enhanced short message service in Chinese. Compared with SMS, it has the advantage that it can not only send short text information like SMS, but also send simple information such as images, sounds and animations. Its greater advantage is that EMS can still run on the GSM network where SMS was originally run, and there is no difference in sending mode and operation method. The standard is open, so any third-party company or individual interested in EMS can develop application software and services on this platform. However, due to the incompatibility of technologies of mobile phone brands, the above-mentioned mutual transmission can only be realized between mobile phones of the same brand in actual use, and the practicability needs to be further improved.
