(HELP) Urgent help needed..
I have MMX A110. I was using BSNL 3G on it from last 6 months but last suddenly it stopped working. I have come to know that if I put any 3G enabled card on slot 1 and activate 3g on phone then I can't make/receive calls, balance check and can't use internet too.
But if I put 2g card and do off 3g on phone then it works fine.
I took phone to service centre they re installed JB4.1.1 but no result.
So anybody here can help me?
Because previously I had A100 and XDA made a lot help to me.
