I have been consisitently faced a network problem in my phone. Both SIM 1 and SIM 2 are affected.
even when the netwrok shows full signal, the phone is unreachable and can’t make any call.
Diag:
1. Software update through Sony PC Companion 2.1.
2. Software update by local sony authorised service centre.
3. Different service provider like Airtel, Voda fone with old /new SIM card at multilocation.
4. Tried all conbination like SIM1 - WCDMA Preferred /GSM , WCDMA only, SIM2 GSM only. (In my case SIM1 user for 3G Data+voice call SIM2 used for only voice calls).
till problem in unsolved.
Now Local service centre wants to OPEN THE PHONE & fix it (the hardware) but I don't want some body will do a R&D on my 2 months old phone and return back to me with lots of dammage/ Scratches.
Please help.
@ Rickard, Alexander,
Can you give me a brief why service center people want to open and check the hardware for Network and wify issue or what need will be check /repair inside the phone.
Can I get a replacement instead of repair?

Kindly response us
All are having the same problem with the same T2 Ultra Dual. The Sony website is now clearly mentioning about July as the KitKat update, but not sure if ALL these problems of camera, sound, network will get solved.
