I just got my first bill for a period starting on a date weeks before I even got the sim card. My phones were suspended for none payment, but my account had a 0 balance. After paying, now my bill has an unpaid balance of $20+? I also have a current balance of $100+. The billing is very confusing. So is this current balance for my previous usage or for the coming month? This is postpaid, so I'm thinking I get billed after I use the service. Why am I getting billed twice on my first bill?
