Just joined O2 mobile, from Tesco mobile, as I want to have a cellular connection on my Ultra. Old number ported across successfully yesterday, but when I try to set up the data plan, instead of getting the sign in screen for My O2, I am getting error 106 and a message to contact support. Support have no idea what the issue is and have escalated to Tech support. Does anyone know what the issue/solution is? Looks to be several people reporting this on various forums, but no resolution to date that I can see.
