Have an old cell phone? It may stop working soon.
Cell phones operating on the T-Mobile and AT&T networks will stop working soon (as early as January 2021) if they don’t support the 4G/LTE calling standard VoLTE (Voice over LTE). Cell phones without VoLTE support on the Verizon network stopped working in 2020.
If you have an older non-compatible phone hopefully you’ve already been contacted by your carrier to arrange for a replacement. But if you only turn on your cell phone occasionally for emergency use, chances are that you may not know about the impending inability to make phone calls. If the last sentence describes your phone usage, now is the time to check with your wireless phone service provider.
