I have a prepaid Orange data SIM. Could anyone tell me please how to register the SIM card so that I can check balance and top up online. I have tried to do this on the Orange et moi site but it won't accept the SIM card number. I have asked in an Orange shop and they didn't know how to do it. I won't always be near a large town so it would be really useful to be able to manage my data online.
Thanks in anticipation
