Had a Virgin sim card , monthly one for roaming abroad (Spain and Ireland) . O2 one now, think that 02 and Virgin merged, the Virgin one picked up G4 all the way up thro Spain and Ireland. Pissed off that the 02 one only gives me G2 even in a city like Malaga. Other half has 02 on a contract and its fine G4 signal, wondering if O2 have restricted the new sim cards ( monthly version) ?
