Okay, here's the problem
I ran out of money and during the time period where my balance was at zero dollars I DEFINETLY got a text message, now when am i going to recieve my missed text message/s?
If someone sends you a message while your account is at $0 it is stored in the system for about 72 hours. If you top up before that time is up then you will receive your messages. After that, the message is deleted and lost forever. The 72 hour thing applies to all messages for all clients because not everyone leaves their phone on all the time and the system will send the message when you turn on your phone. Most people don't leave their phone off for 3 days.
