[ujjal]

@Rickard, Alexander,

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.

Dears,

Is there any solution to this problem?????  The only solution I found is to remove SIM 2 and stop using it. This is very disappointing as I bought the 2 SIM mobile to satisfy my need.
