Hi. I have a question about telecom and iPad. I have an iPad and I have a telecom prepay sim that I use with it. My question is I know that when you top up on line it will send a text code to activate it. Can I just put my microsim into my iPhone 4 to get the activation code? Is it a simple case of just inserting the card and the text will immediately show or do I need to muck around with settings?

Thanks for any help
