Nothing stopping you from buying a phone of your choosing then just chucking in a sim that suits you like GiffGaff. £10 unlimited texts and data, 250 mins.|
Personally i got sick of 2 year contracts as your paying extra for a phone, which wont keep 2 years anyway. Remember £40 X 24 = £960 then deduct £240 for the line rental and you basically paid £720 for the phone. And if sell/replace after 1 year it will hold value better than if after 2 years.
