Bag a phone for less than £5 at Carphone Warehouse. Probably the lowest-price way to get a mobile phone, you can now get a Pay As You Go handset for £4.95.

The Samsung B130 has a colour screen and GPRS Internet access, and is available now on Orange or T-Mobile.

You do have to buy £10 of credit to be able to use the phone, but £4.95 for a perfectly respectable Samsung is a steal. Available from Carphone Warehouse.
