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 [email protected]

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]

K750i "Insert SIM"


do all the contact pins on the phone reach the simcard?
you can try to pull them up a little bit carefully.

i had the same problem - you will need to flash your phone with the newer firmware. is your M2 a 2gig? mine was.

After i flashed it , it worked great - you can use wotan server or contact me as we flash those all day long - horizonwirelessonline.com

thanks
