Earlier this year, we began sending letters, emails, and text messages to a small number of smartphone customers who use their devices for tethering but aren’t on our required tethering plan. Our goal here is fairness for all of our customers. (This impacts a only small percentage of our smartphone customer base.)
The letters outline three choices:
1) Stop tethering and keep their current plan (including grandfathered unlimited plan)
2) Proactively call AT&T or visit our stores and move to the required tethering plan
3) Do nothing and we’ll go ahead and add the tethering plan on their behalf — after the dated noted in their customer notification
AT&T has confirmed the above to be true, so just enjoy whatever time you have left – AT&T did not give a hard cutoff date, but since it can be anytime, this is where the adage “every second counts” comes into play.
