I am UK based and have an iPad 3rd generation under iOS 3.3(12F69) with all apps fully up to date and previously used almost exclusively on wifi. I did once have a SAMBA SIM for 3G but they went bust a while ago so I have now acquired an People's Operator SIM which piggybacks on the EE network. However, even though it appears to be configured correctly, all I get is "No service" messages whenever I try to switch from wifi to 3G. The People's Operator have spent a fair amount of time trying to get me up and running but have now decided that the problem lies with the iPad and not their SIM or EE's network. They reached this conclusion after we swapped their SIM into my normal mobile phone and it worked perfectly, evidence which they say proves the network is strong here and the SIM is fully functional - and I cannot argue with that! I have done a full reset (not just a reboot) so, why does the iPad always state, after searching, that there is "No service"? It must be able to see the SIM or else it would say No Sim Installed (or somesuch). What setting etc. could be wrong, or what else might be stopping the iPad seeing the EE signal? What am I overlooking?
