Not able to use 3g mode

[Viks1107]

In my new xperia E3 the network is set to GSM only mode, and i am trying to change it to WCDMA mode but it is not changing. It is automatically set back into gsm only mode again and again.. Please help

Do you have the dual version?

[Viks1107]

Yes

If you are trying to use the second SIM on 3G,it won't work.

I am using SIM 1 for data traffic and mode is set in gsm only.. And i am trying it to change into WCDMA.. But result is negative

This is strange,I know that second SIM can't be used on WCDMA.I am not sure,can you check if the same occurs in safe mode?
