As I said before I suggested GiffGaff, O2 may be your best bet.
With regard to coverage, it's worth understanding the frequencies of each network:
- Vodafone - 900, 1800 & 2100
- O2 - 900, 1800 & 2100
- Orange - 1800 & 2100
- T-Mobile - 1800 & 2100
- Three - 2100
Lower frequencies penetrate buildings much better, so Vodafone and O2 have a slight advantage. However, Orange and T-Mobile recently merged and you can now roam between both networks free of charge, meaning you get two networks' coverage as a customer of just one network. Consequently coverage on these two is arguably better now than Vodafone or O2. Avoid Three, which only has 3G coverage; everyone I know on Three complains about coverage and lack of signal.
