3g sunset and iphone

Here in the U.S., all three of the major networks - AT&T, T-Mobile/Sprint and Verizon - will have completed the shutdown of their 3G networks by February, March and December 2022 respectively, as per linked article. Hence, the urgency of knowing how this will impact me and a lot of other people.

Sorry, did not complete the link attachment the first time.

If I knew the answer to that, I would not be on this forum. My phone lists "3G" and "LTE" as two separate options for voice & data. No mention of 4G. Does "LTE" by itself mean the phone will keep working? I don't know. And if the phone will stop working, how far to I need to upgrade? If my carrier is to be believed, nothing short of an iPhone 12 or 13 will function on a major network by the end of 2022. Second gen SE and iPhone 11 would not make the cut.

Hmm. It may be that Boost is hectoring me to upgrade my phone because, in addition to shutting down 3G in March, it will be shutting down Sprint’s 4G LTE network in June. As a former VM customer who got shunted over to Boost when Virgin got out of the mobile business, my phone uses the Sprint network. In that case, what I need is not a new phone, but a new provider that is still operating a 4G LTE network. Maybe not AT&T - aren’t they CDMA? My phone is currently GMS.

Thank you, that is the answer I needed. Boost has been very opaque about the whole thing, telling customers like me that we need new phones rather than a different, compatible network.
