When you receive the Sim kit, the info on the Sim kit will that be your login info to your prepaid account? I've been trying to make an account and it won't let me. Also the phone number you get in the email they send you as your confirmation will that be your phone number used to login? How does this work its my first time using this carrier. The amount due each month is that a fixed pay meaning will the pay stay the same each month your charged or will it change depending how much data you've used on the plan.
