I used the settings from the48 site tweaker guide it comes up as tesco mobile is the carrier and is active the mms and internet also register on the screen, but they say inactive, when i pressed on internet and mms it became active and internet worked i think the tesco mobile being active is blocking the 48 network, because everthing else u scroll tru in settings 48 is ur carrier but on the apns screen it wont allow you erase the tesco mobile you just deactivate it by activating intternet amd mms below it by touching the screen. gsamon1995
