If they issued you a phone number the activation did work
If you have "no idea" about your number chances are no number was assigned (since you need to PICK a number when activating) so they would not have billed you
please return my money. The activation didn't work on my sim card thank you and have no idea now what my phone number is.
Sorry to hear your activation issues. Please give us more information what had happened and what is working or not working? With more information, we will get your new activation working.
