I have my Sony Ericson Cybershot which is under contract and after a year, I read this
" PLEASE INSERT CORRECT USIM" I tried to remove sim and battery and placed it again and next I read is this
" NO NETWORK COVERAGE"
Tried to seek MY3 support and told them about this. They advised me to connect my mobile to my laptop for an update. But when I did it, it's low battery so I tried to charge it. But I read this:
Please use correct Sony Ericson Battery!!!!
