Here is some information that we pulled from the FCC’s website that may interest you:
Mobile carriers are shutting down their 3G networks, which rely on older technology, to make room for more advanced network services, including 5G. As a result, many older IoT devices will no longer be able to communicate for their data services. It is important to plan now so that you don’t lose connectivity.
What This Means for Customers
Customers who still have 3G / CDMA-only devices will need to upgrade or risk losing connectivity to these devices. By upgrading, customers will benefit from newer future-proof hardware that communicates on wireless technologies such as LTE and 5G.
Key Dates
- AT&T shut down 3G GSM/UMTS—February 2022
- T-Mobile shut down for Sprint customers—March 31, 2022
- T-Mobile shut down 3G GSM/UMTS—April 2022
- T-Mobile shut down 2G GSM—December 2022
- Verizon shut down 3G CDMA—December 31, 2022
If your mobile carrier is not listed here, you may still be affected. Many carriers, such as Cricket, Boost, Straight Talk, and several Lifeline mobile service providers, utilize AT&T’s, Verizon’s, and T-Mobile’s networks.
