No Network since update on S3

[Anonymous]

Hi Please can someone help?? I recently updated my Samsung S3 to Jelly Bean and I can longer connect to O2 network. I have reset my phone to factory settings but still nothing

Text ACTIVE to 2020, save the settings and reboot the phone. Search the network settings and try to connect to O2 manually.

Also try cleaning the sim card and check for any network problems on the status link in my signature.

I would try resetting the phone again and if no luck try as Jonsie says and see if you can select the O2 network manually
