Why is my 3 Dongle working without any credit on it
Just bought a 3 dongle from Tesco for £9.99, if you buy a £10 top up voucher with it. I havent loaded the voucher on it yet, but the dongle is connecting to the internet and works fine. It didnt come pre-loaded and when i check the my3 account it says £0.00 balance. Why? is there a free period?
