Sounds like a silly question but did you update the phone via the SE suite or via a flash updater? there may be problems if you left your sim in, if you flashed the phone. If you updated via the SE suite then take a look at the troubleshooting guide and moan to SE. As long as you haven't voided the warrenty on your phone there should be no problem with SE or your service provider repairing your phone for free. :)

Hope this helps. One last thing to try is to out another sim in the phone and see if it works. With any other provider except O2 you will need to use a sim the same as yours.

My sony ericsson keeps saying inactive sim turning itself off n on again then searching n coimg back to orange it has now started to delete my call history when it does this

Sony ericsson phones are notorious for this problem. Its a software prob. You can try and update the software on your handset via sony ericsson website, or take it back to the retailer and they will send it back to sony ericsson ( if you bought it from network retailer only) places like argos etc wont touch it. Try going to settings on your phone, below profiles it should say that and you should be able to get a newer software that might not have any bugs. good luck!!

Inactive SIM problem in Sony Ericsson w760i.

Hi mslsweden,
It does sound like the sim reader might be malfunctioning or the sim card could be worn.
in this case i would recommend you simply try another sim card with the same network before assuming its the sim card reader.

I hope this helps :)

Cant unblock my sony erricson phone it keeps saying sim inactive

Could be two reasons: Your phone is already blacklisted (if bought secondhand the owner reported lost/stolen) or the phone is locked to certain network. And might be your SIM was deactivated (try it in different device if works).

Phone does not accept any sim cards recently- says inactive sim

the phone needs to be diagnosed so take the phone to a mobile service center and have them correct it.

When you try to turn it on, look by the infared port... is there a flashing red led for about 2-3 seconds? if so... Please check out post from:
