AT&T has noticed usage patterns in some of their unlimited data plan users that suggests these users are tethering their phones without paying the $45 data plan which includes tethering. AT&T has begun to send out emails and text messages to users they feel are taking advantage of being grandfathered into unlimited data plans which ended last summer with the introduction of tiered data.
AT&T offers three options for those people tethering without their permission
– Stop unauthorized tethering and keep your plan
– Sign up for the 4gb Data pro plan ($45)
– Do nothing and automatically be enrolled in the $45 plan
AT&T has often been plagued with bandwidth problems, especially in heavily populated areas and the unauthorized tethering must be adding to the problem. This approach does seem a little aggressive though and other than usage graphs we’re not sure how they could have stumbled across this data.
