Recently I went to the Isle of Man for a trip, with the network over there being run by O2 called Manx Pronto (or something). Anyway, now I'm back and my carrier is STILL Manx Pronto, despite me being nowhere near the Isle of Man. Tried manually selecting the network, if I pick O2 - UK it simply comes up as Manx again, but O2.ie comes up as usual. I'm a bit afraid of using my phone and being stung for roaming charges despite being in my home! Does anyone know how to reset this back to O2 - UK?
