Xperia m4 aqua sim card problem

[Yudum]

Hi everybody! Hope your first days of 2016 going well. Not Like me 😕 My Phone cannot receive any calls or i cannot give any calls right now. I can see 'sim card not working icon' on top of the screen, but i can see My numbers which are saved to sim card. Also i tried My sim card on another Phone. IT is working with other Phones. What is wrong with My Phone? I bought it Just 3 months ago! I need to solve this problem asap because i am using this Phone for My business.

contact your carrier and check if your phone's IMEI number was reported as stolen, also you can test a brand new SIM card, make sure that its the correct size, do NOT use trimmed/cut SIM cards.

No it is not stolen,i already checked imei number also i have warranty. I changed My sim card when i bought the Phone. IT is completely suitable with the Phone. Can it be A software problem?

I'm having the same or similar issues with my M4 on a LTE SIM, doesn't connect LTE, and starts a cycle H+ - H - Emergency Calls and H+ again, each 2 or 3 minutes. On january 2nd, they put a 3G SIM, not LTE, and everything worked fine.

Went to the Telco today after testing and installed a new 4G/LTE SIM and the issues reappeared, the people at the Telco told me that this particular model of M4 Aqua (E2303) is not working with certain 4G/LTE SIM cards....

Anyone?

Very similar issue with my brand new M4 acqua. Bought it yesterday from the local service provider store. It was working very fine and suddenly it cannot connect anymore. Even using safe mode it's not connecting.

Yes Even im facing same issue. Gave it to service center. They replaced Mother board all worked fine. But Mobile they gave was Dented all over and Back flip was not sealed properly.
