O2 in Truro is on the piazza near Marks and Spencer's. It is fairly small but it can get quite busy…read moreas times. I bought my most recent phone from here and found the shop overall to be very good. The prices are slightly higher than on over networks on pay as you go but there are ways to save money. If you are already a O2 pay as you go sim card with credit, it is worth looking here as they let me get a new phone without a new sim card for cheaper. Another way to save money is to bring in an old phone to trade in, they will then take £10 off the price of your new phone and send the old one to charity. Although it can be quite busy the staff are friendly and I did not feel rushed. They may not be the cheapest but the staff are good.
