My K750i won't turn on


This is because Operating System (OS) of your mobile has been corrupted. U can't do anything to fix this by yourself. U can get it repaired only by contacting nearby SE authorised service centre. [Even i had a same experience in my SE W810i]

I switch on my Sony Ericsson W8801 mobile and it tells me to insert SIM even though it is inserted! Ive tried most things but nothing seems to work.(Only a few months old and lost the receit


Check the sim card slot of your phone, it might be loose that causes the sim card to lost contact with the connectors of your phone. Thus, your phone can't recognize and can't detect the card inside...

Hi! This may sound weird but have you tried checking if the sim holder is loose? Maybe the sim is not touching the terminals on the phone.

SE K750i displaying 'insert sim' even though sim is inside.


This problem is due to your phone's sim card IC malfunctioning. It may get damaged due to phone dropping gently into rough surface and its crystal structure may break due to it. for any queries mail to mahesh_vr@yahoo.com
