One Samsung GT-C 3010S has a peculiar problem. If I put an AIRTEL SIM into it works fine. But when I am trying other SIMs like BSNL, VODAFONE , TATA DOCOMOetc. The phone accepts but does not show any network. When I am searching the network manually, all the network prividers ares hown in the list but when I am trying to save one, it cannot save and shows “failed”.
Please help me out.
