I got one of those 3 prepaid international SIM cards which lasts for a month. Got a text today saying it will expire in a few days and I can go to a link to top it up if necessary. But the link asks for the phone number and I have NO CLUE what the number is! Any ideas how to find the phone number of a data sim (which will not text, tried that).
Has anyone tried topping one of these up?
