Re: SMS Lifetime on SMSC

hey guys,

Thanks for the replies. I posted my questions only after giving T-
Mobile CSR a try. Nobody there seemed to know the answers. I just gave
CSR another try and found someone in Tier 2 tech sup****t who
supposedly found the answers. As both of you guys mentioned, it seems
the validity period for SMSs on the T-Mobile SMSC is 72 hours.
However, the Rep told me that if the SMS doesn't successfully reach
the phone, it is not charged. It seems that the phone's
acknowledgement of having received the SMS is what triggers billing.

Anybody know for sure the point at which billing is triggered?

Thanks!
