Insert sim problem 1100,1600


sometimes it is as simple as cleaning the sim card and sim points on the phone with a pencil eraser. sometimes it is related to a simcard IC (usually placed close to the sim tray in the phone) so if u do not succeed cleaning the sim and sim points of the phone u need to change the simcard IC

Says insert sim card when there is one in it


"Insert SIM" message is normally displayed on phones when a SIM card is not inserted on power-on or it does not detect the SIM card inserted.

Likely Causes:
  1. No SIM card inserted or inserted SIM card is damaged
  2. Inserted SIM card not positioned well in such a way as to make contact with the corresponding contact bridges on phone.
  3. Phone locked to a specific network and can only work on other networks when the firmware version is "flashed", that is completely changed to an unlocked version.
  4. The phone might be faulty (try with another good SIM, if you still get thesame message and its not one of the above reasons... it might be a transciever problem or the phone's SIM card slot's pins might be defective).
cheers.

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
