Hello
I'm sorry to hear your text message usage is not showing up on your account.
About usage reporting delays
We update your usage to your online account as quickly as we can, but in some circumstances usage information may be unavailable or delayed. We post recent data usage details (since your last bill) online after myAT&T receives this information, which can sometimes take 2-5 days.
I apologize for any inconvenience this may cause.
Thank you,
Michelle
