As the now confused
OP can I just ask .......
Is the general concensus that you can use the Rebel Card for unlocking the Hero but that you need the APN settings of the provider of the SIM card you are using with the Rebel Card if you want to get data?
If so then I think the idea of a sticky giving those would be very useful - one that people can add their ones to. Can I ask that it covers all providers (both contract and PAYG) in all countries please, as my only reason at present for using the Rebel Card will be when I am roaming and want to use a local PAYG SIM to save the exhorbitant roaming charges.
BTW I would like to hear from anybody that has (successfully or unsuccessfully) used it in that way.
