Dear,

If the phone freezes

  1. Press and hold the on/off key.
  2. If your phone does not power down, remove the battery for 10 seconds, insert it again, and restart the phone.

Note: Use The Sony Ericsson Update Service regularly to reduce the risk of software problems. Make regular backups using Sony Ericsson PC Suite to reduce the risk of lost or corrupted information.

regards,

You could try to remove your sim card.
Install battery and turn on phone without sim card.
Use phone without sim card and do some operations.
This will check if you phone is working correctly.
Turn phone off and install sim card.
Made sure sim card is install correctly.
If this does not work, it could be the sim card is bad.

Always show the message 'insert sim card', When I refitted the SIM and turned back on, I had no network coverage. it always again n again n again..


Hi,when a phone does that, it means that the memmory of the phone is malfunction and it needs to be restored..
To be able to restore back the phone memory, you will need to flash the phone memory.

Reset my cellphone


If the display says "Insert SIM," it means that the phone has no contact with your subscription card (SIM card) that is inserted in the phone. We recommend that you remove the battery and the SIM card, and clean the connectors on the SIM card and the phone with a soft brush, cloth or Q-tip moistened with any type of unflavored colorless alcohol.
At the same time, check that the card is not damaged or worn in any way, in that case, the connector may not align with the connector in the phone. Please contact your operator / carrier for a new SIM card.

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

Insert sim


Its possible that the sim card on your phone is not properly placed or the sim card that you own has some problems already.

Try to reinsert your sim card, this time make sure that it is properly placed. If the same happens, try to use a different sim card on your phone. If there are no problems, that means your sim card might be busted already. If the same happens with another sim card, then it is possible that the slot for the sim on your phone is defective or dirty. You may need to have it checked. :)

Phone doesn't recognize the SIM card


The sim card holder has a tiny slide mechanism. After inserting the sim card and pressing it against the body of the phone, place your finger over the card and slide it gently forward. The tiny plastic part that holds the card will snap it into place. Hard to explain, but it will work.
