Put a small amount of pressure on the back of the phone level with the camera slider. Then push towards the base of the phone and the back should just slide off.

My sony ericsson vivaz is not sending text sim card is working..

Please try to check the SMS network configuration settings of your phone through your Service Provider. They need to reconfigure your account to activate this feature on the phone.
If this seems to be fine, then try the following:
1) Go to your outbox and cancel sending the message. It should have an X on it or something.
2) Take out your battery without turning it off first.
3) Remove your SIM card and put your battery back in.
4) Boot your phone back up without the SIM card.
5) After it boots all the way up, remove the battery again without turning your phone off.
6) Put your SIM card and battery back in and turn your phone back on.
7) Go to your outbox and delete your canceled message(dont try sending it again).

I changed sim card, now they both display ''Insert SIM''

try taking out both cards and popping the battery on the phone.

Wait a few minutes and then turn the phone on with no card in it.

Turn it back off when it says no card found and insert the newer card and power it back up.

It seemed to keep a memory of the blank card.

Forget security code

if your sim is locked, remove ur sim from ur mobile and note down the numbers back on ur sim card. then call ur network operator and say ur problem, then they wil ask numbers back on ur sim. they wil say some puk code , then enter it in ur mobile.
