Prepaid UK SIM

[Bossman]

I believe you went under the credit card option. Those options sound credit card related. The fact that it asks for the amount and the security code makes me think it's credit card. For voucher topup, just the voucher # is required. There should be an option for voucher topup. And, it should not matter if you are doing it from outside the UK.

It asks for the amount, then the last 4 digits of the card number (which I assume is the 16 digit code). Then it asks for the card security code (which I assume is the SIM card PIN). When I try to enter this information, I get an message that says error sending message.

Is this because the SIM card has not yet registered on T-Mobile in the UK? The customer service rep at T-Mobile UK said that should not make a difference.
