I would be getting a PAYG SIM for data (therefore 3G) in the 2+ weeks I'm in the UK. I know which company offers the cheapest package, but would like to get one that has decent coverage in most of the following places.
I would like suggestions on the best 3G mobile network for travelling in Glasgow/Edinburgh, Lake District, Liverpool and London? I'm hoping someone who has been to either of these places with the same SIM card could pop by and give their thoughts.
p/s: My phone is unlocked so no problems there.
