O2 have announced that the problems with their network are now fixed and that all Tesco mobiles using the O2 network should now be working ok.
If your Tesco mobile still has a problem the advice is to turn it off and back on which should restore the signal. If you had switched off 3G to get the phone working yesterday you should now be able to switch it back on again.
Please leave a comment if you are still experiencing problems with Tesco Mobile or feedback on your experiences yesterday.
