Just ordered a Gevey Ultra Sim and a sim cutter for my trip to UK in August. Can anyone recommend a good PAYG network for 3G internet, mobile calls and texts? I came across 'three - PAYG' and they do 30 days unlimited data, 300 mins, 3000 texts for just 15 GBP. This seems a little too good to be true - will this work fine with a cut down sim in an iPhone 4? P.S. Do the UK PAYG sims have the smaller printed circuit board for ease of cutting (I botched a few practice sims using scissors hence why I bought a cutter)? ** UPDATED ** Cancelled sim cutter order as most networks provide a micro sim. Summary of best networks: Vodafone: 300 min, 3000 texts, 500MB web £20 Three: 300 min, 3000 texts, unlimited web £15 GiffGaff (Uses O2 network) 250 min, unlimited texts, unlimited web £10 / £15 for 400 mins / £20 for 800 mins Can't believe how cheap and competitive PAYG has become in the UK. Thanks to all that replied.
