Senior Alert: Your old cellphone may not work in 2022

A human hand holds a flip-phone.

Dear Savvy Senior,
My 80-year-old father has an old flip phone he carries around with him for emergency purposes, but Iíve heard that these devices will soon be phased out. Is this true? If so, how can we know if his phone will be affected, and where can I find him a simple new one that he can operate.
--Searching Daughter

Dear Searching,
Yes, itís true! If your dadís mobile phone is more than a few years old, he will probably need to upgrade it in the very near future.


Because all of the major cell phone carriers Ė AT&T, Verizon and T-Mobile Ė are shutting down their older 3G networks in 2022 to free up airwaves for 5G and other advanced services. So, if your dad is using an old 3G phone, like millions of other older Americans, heíll need to get a new device if he wants to make calls, text or reach 911.

But you should also know that itís not just older cellphones that will be obsolete. Older home security systems, medical devices and personal emergency response systems that still harness 3G will also be affected. Adding to the confusion, older 4G phones that donít support modern cellular voice technologies, such as Voice Over LTE or HD Voice, are impacted, too. Those customers may need a software upgrade or a new phone.

Here are the timelines for the 3G shutdowns: AT&T - Feb. 2022; T-Mobile - July 1, 2022; Verizon - Dec. 31, 2022; Sprint (which is owned by T-Mobile) - March 31, 2022; and Sprint LTE - June 30, 2022. Other smaller carriers like Tracfone, Cricket, Boost and Straight Talk, will also be affected, because they rely on airwaves from the big three.

Is Your Phone Affected?
Cellphone carriers say they have been alerting customers who use older phones that services are ending, sending a combination of texts, letters, phone calls and emails. If youíre not sure about your dadís phone, contact his carrier or check their website for a list of affected devices.

Another way to see if your dadís phone is 3G is to look up his international mobile equipment identity number which can be found by pressing *#06# on his keypad. Once you have it, go to and type it in the search bar to get the phoneís details. If his phone has a frequency of 900 megahertz (Mhz) or 2100 Mhz, itís 3G. You can also look for a ď3GĒ icon at the top corner of his phone, but not all 3G phones have that icon.

How to Upgrade
If you find that you do need to upgrade your dadís cellphone, carriers are offering discounts and special promotions on replacement devices. If youíre worried about your dad having to learn your way around a new device, youíll be happy to know that there are plenty of modern new flip phones available that work on the next-generation networks.

Or, if your dad decides that he would rather forge ahead without a phone than upgrade, then he will need to cancel the service. Most carriers will let you cancel your plan without any penalty. However, if he forgets to cancel his phone plan and doesnít upgrade to a working device, the company wonít automatically stop charging him just because he isnít able to access their network.

How to Recycle
If your dad does have to replace his old cellphone, the best way to dispose of it is to recycle it. Large retailers, such as Best Buy, offer recycling programs for old electronics. Or you can search for local recycling programs on websites like and
