This is my first month with a pre-paid phone and I have a questions about topping up. The due date for my account is 3/8/11. I just made a payment to my account for the next month. Will this automatically be applied? So far it is still showing a due date of 3/8/11. Do I need to take further actions? This morning I received a response to a text that I sent that it would not go through due to a low balance. After adding to the account everything is fine. Is this normal? How to other people pay? Do you pay monthly or setup for an automatic charge?
