AT&T’s 3G network was the first of the carriers’ to be shut down. Next on the list is Sprint. Since its merger with T-Mobile in April 2020, this network is currently controlled by T-Mobile. The sunset of the Sprint 3G (CDMA) network is part of T-Mobile’s network evolution plan to make LTE and 5G services available to more users nationwide.
Here’s the alert that was sent to customers just recently:
–
Dear Customer,
On March 31, 2022, Sprint’s older 3G (CDMA) network will be retired. Customers still using a device that is dependent on Sprint’s 3G (CDMA) network or that does not support VoLTE will need to upgrade to a more modern device to continue getting service, including the ability to make 911 calls depending on your location.
Some device models that will need to be upgraded include:
- Devices (handsets, IoT/M2M, tablets and air cards) that operate solely on the Sprint CDMA Network
- Devices that operate using dual mode CDMA/LTE or LTE technologies that do not support Voice over LTE (“VoLTE”)
For additional information, see here.
We understand the importance of being able to plan for these network changes and we are committed to keeping you informed with up-to-date information.
Thank you for being a T-Mobile for Business Partner.
Sincerely,
Your Partner Program Team
