So far no one, so far as I know from looking at multiple forums, has either received anything with low data usage, i.e. under 1gb, or from using TetherMe. However, someone posted this, which may be of interest.
ATT internal info concerning tethering:......................
As of March 17, we will be sending notification to subscribers who are currently tethering without the appropriate and required smartphone data plan which is DataPro 4GB for Smartphone Tethering.
Process to Bring Account in Line With Policy
..............
Why Are We Doing This?
Customers tethering without the appropriate data plan are not in line with the requirements of their Wireless Customer Agreement. Review this from the Related Links section.
When Does The Communication Start?
The notifications begin to go out on March 17, 2011.
Which Customers Are We Addressing?
...............
We will be notifying customers in stages, however, the plan is to eventually identify and notify all customers tethering with a smartphone, regardless of the type, without the required data plan.
How Will They Be Notified?
Notifications are sent by e-mail, SMS, and a letter sent through U.S. mail.
.............
Customers may either bring their account up to date as requested or they may choose to discontinue tethering and remain on their current data plan.
If they continue to tether and do not change their data plan to DataPro 4GB for Smartphone Tethering, a second notification will be sent informing them that we have moved them to DataPro 4GB for Smartphone Tethering, as we informed them in the first communication.
Secondary notifications will also be sent via U.S. mail, e-mail, and SMS. Refer to the Related Links section to review samples.
Frequently Asked Questions
Which plan are customers automatically moved to if they do not bring their account in line with our policy?
They are moved to 4GB for Smartphone Tethering. The $45.00/month plan includes 4GB of data per month; $10.00 for each additional GB thereafter, added automatically as needed. Mobile Hotspot capabilities are included for compatible smartphones. Refer to the Related Links section for more information.
How does this work with customers currently on a Smartphone Data Unlimited plan?
Handle business as usual. We do not offer a tethering option for subscribers who wish to remain on their Smartphone Data Unlimited plan. However, the customer can keep their unlimited data plan if they stop tethering. If they wish to continue to tether, they will need to move to DataPro 4GB for Smartphone Tethering to align with our policy.
Once a customer moves to DataPro 4GB for Smartphone Tethering, whether they do so on their own or we automatically update their account, the customer will no longer have the option to return to the Smartphone Data Unlimited plan.
Similar to date as well: SIM Swapping
Appropriate data plans are required to use Mobile Broadband devices (laptop, tablets, or AT&T Mobile Hotspot devices) on the AT&T Network.
Effective March 16, 2011, AT&T will systematically enforce this policy by alerting customers with unlimited data plans when they take the SIM from their current smartphone, QMP, or basic phone and place it into a Mobile Broadband device to access data unlimited, that an appropriate data plan is required.
..........................
If the customer continues to use their smartphone SIM in their Mobile Broadband device, their data service will be suspended until the end of the billing period, unless the customer calls into Customer Care to add the appropriate data plan.
Note: If the customer does not contact Customer Care to add a plan, their data service will be restored for their smartphone at the beginning of the new billing cycle. If SIM swapping activity is detected during the next billing cycle, the data service on the account will be suspended again.
Is my customer eligible for a data credit while his data service is suspended?
No.
Can my customer continue this process each billing cycle?
No. If the customer continues the out of policy behavior, AT&T reserves the right to remove the unlimited smartphone data plan from the account.
