A&T Data Plan Rip off Update

Shame on you AT&T.
You are about to lose a customer from this email:

Dear Rocio Rosales, We've noticed your service plan may need updating. Many AT&T customers use their smartphones as a broadband connection for other devices, like laptops, netbooks or other smartphones– a practice commonly known as tethering. Tethering can be an efficient way for our customers to enjoy the benefits of AT&T's mobile broadband network and use more than one device to stay in touch with important people and information. To take advantage of this feature, we require that in addition to a data plan, you also have a tethering plan. Our records show that you use this capability, but are not subscribed to our tethering plan.  If you would like to continue tethering, please log into your account online atwww.wireless.att.com, or call us at 866-975-0004, Monday - Friday, 7 a.m. - 9 p.m. CT, or Saturday, 8 a.m. - 7 p.m. CT, to sign up for the DataPro 4GB for Smartphone Tethering plan or the DataPro Enterprise 4GB for Smartphone Tethering plan.		Please update your data plan by the end of the month if you intend to continue tethering.

Here are details on the plans:  DataPro 4GB for Smartphone Tethering • $45 per month (this gives you 4GB in total, combining both your smartphone data plan for $25 and the tethering feature, $20) • $10 per each additional GB thereafter, added automatically as needed • Mobile Hotspot capabilities are included for compatible Smartphones DataPro Enterprise 4GB for Smartphone Tethering  This Enterprise data plan is required to access corporate email, company intranet sites and/or other business applications. (Access to personal email is also supported.) • $60 per month (this gives you 4GB in total, combining both your smartphone data plan for $40 and the tethering feature, $20) • $10 per each additional GB thereafter, added automatically as needed • Mobile Hotspot capabilities are included for compatible Smartphones If we don't hear from you, we'll plan to automatically enroll you into one of the above DataPro 4GB plans in an upcoming bill cycle. The specific plan selected for you will depend on your current smartphone data plan; if you are currently subscribed to another Enterprise data plan, you will automatically be enrolled in the DataPro Enterprise 4GB for Smartphone Tethering Plan so that you can continue to access corporate email and applications. Your new DataPro 4GB plan – whether you sign up on your own or we automatically enroll you – will replace your current smartphone data plan, including if you are on an unlimited data plan. If you discontinue tethering by the end of this month, no changes to your current plan will be required. It's easy to track your usage throughout the month so there are no bill surprises. For example, we send you free text messages when you reach 65, 90, and 100 percent of your plan's threshold. If you would like to monitor your account more closely, go to www.att.com/dataplansto learn about other ways to track your data usage. As a reminder, our smartphone data plans also include unlimited usage of Wi-Fi at no additional charge. AT&T smartphone customers can use Wi-Fi at home or on-the-go at any one of our more than 23,000 U.S. hotspots already included in your data plan. Thank you for bringing your account up to date. We appreciate the opportunity to continue to serve your mobile broadband needs. Sincerely, AT&T
