I have a Xperia V device which worked fine until few days ago. I still use 3G SIM, and I've enabled WCDMA(preffered)/GSM from settings menu (Settings->More>Mobile Networks->Network Mode). This works perfectly fine until few days ago. I usually get 3G signal, rarely 2G.
One day suddenly I found that phone with no mobile network connection. I thought maybe something wrong with signal coverage. But it didn't changed even after I changed my location. I has few options in Network Mode menu as follows,
- WCDMA only
- GSM only
If I choose anything with WCDMA, phone gets disconnected from the carrier and I can only use the option GSM only whyich gets the connection.
I haven't updated or rooted or did anything to the phone recently.
I tried restarting the phone, toggle flight mode , remove and re-insert the sim card but nothing works.
- Why can't I connect to WCDMA/3G?
- Why am I only able to connect to 2G network?
This happens in every scenario.not on when turn on mobile data connection. I lost signal when I try to connect to any option other than GSM only
