Dont you just put it in and they can recieve calls?
Its only £10 to get the free texts and stuff.
If not put it in and sent Balance to 20202 and that does something and gives them free texts. I done it with ines and i hav 300 free texts for a month without ever topping up and i ecieved texts/calls.
Thanks for the replies, i popped the sim into my 2nd phone now n it received a call just fine without doing anything, though it didnt work last night when i first put it in.
