SMS Center Number becomes Unknown

Viral22 — Sun, 27 Apr 2014 06:00:53 GMT

I have Xperia M dual and the SMS Center Number becomes unknown after 1-2 hrs. Then I have to either restart phone or start Airplane mode and again disable Airplane Mode. This I have to do every time to send the SMS.

If anyone has same problem and solution for this Please Help....

Hi and welcome to the community! Since you're new please be sure that you have checked out our Discussion guidelines.

That sounds strange. Have you tried with different SIM-cards in your phone? If not, I suggest that you begin to change the SIM-card(s).

I have tried that earlier only but it is not working. I have tried it with 4 to 5 sim cards. Every time I am facing the same problem.

If you have tried different SIM-cards, I suggest that you perform a software repair on your unit via PC Companion:
http://www.sonymobile.com/global-en/tools/pc-companion/

In PC Companion you press start on Support Zone > Start on Update the phone/tablet software > Repair phone/tablet (the blue clickable link in the message) > Follow these steps without having your device connected to the PC.

Follow the instruction that appears in the program and do not connect your device until this guide tells you how to connect it.

This is also not working. I have done factory reset as well as above solution but of no use.
