So 2 days ago i have bought this SONY XPERIA ARC S cellphone which i loved totally but after putting my 30 months old bsnl sim mobile showed NO NETWORK COVERAGE. SIM is working absolutely fine in other cell phones, it is even showing the 3G networks but not showing any signals in my ARC. I have tried putting other SIMs in my cell like Aircel, Idea etc and all are working fine. Someone suggested me to replace my old BSNL SIM with new 128k sim. So will this thing work in my phone? Anyone here faced same kind of problem?
Any help or suggestion will be very useful to me. Thanks in advance.
