My wife pretty much never tethered and I did always! But neither of us have in the past couple months since we got comcast again. Today she got a text from att: AT&T Free Msg: We've noticed you're continuing to enjoy the tethering feature with your smartphone service. Remember, you need a tethering plan ($45/mo, incl. 4GB) to use this feature, so we're planning to update your line with the required plan soon. Visit att.com/dataplans or call 866-679-7118. If they try anything, in going to tell them to go "f" themselves and switch to verizon vim sick of this crap. Threaten me all you want, because I did at one point tether, but to send this crap to her phone now is ridiculous.
