This notice may impact others within your organization. Please forward this letter to those individuals in your company who may have mobile communications responsibilities for connected device services.
To help address the growing customer demand for mobile services, AT&T plans to fully discontinue service on our 3G network in February 2022. This will enable us to free up valuable spectrum and provide increased speed and capacity for our more advanced technologies like 4G LTE, low-power wide-area (LPWA) networks and 5G.
In some markets, it may be necessary for us to turn down one band of our owned and operated 3G network, such as 1900 MHz or 850 MHz service, ahead of February 2022.
To prepare for this transition, we are providing notice that you must stop activating or reactivating SIMs that use 3G technology. Specifically, if your agreement with AT&T currently allows 3G activations or reactivations and lists a 3G stop activation date, you must stop on that date. If no date is listed, you must stop within one year from the date of this letter or the end of the 3G stop activation notice period in your agreement, whichever is later.
We strongly encourage our customers to begin migrating all 3G devices to 4G LTE or LPWA networks as soon as possible. Your AT&T account team is ready to offer guidance and expertise to help make this transition as smooth as possible.
We’ve also established a website that provides valuable information on migration planning, specifically for our IoT customers. It provides resources such as a current list of certified 4G LTE and LTE-M equipment manufacturers. Plus, information about our IoT Accelerator Program could provide reduced equipment pricing. We will update the website with new information as it becomes available.
