    CDMA (3G) network retirement

    After December 31st, 2022, if you are a Verizon customer still using a device that is 3G (CDMA) or 4G that does not support HD Voice (Non-VoLTE), the device will no longer make/receive calls,
    send/receive text messages, or use data services.
    Until this date, your device will still be able to use these services.
    Device models that are 3G (CDMA) and 4G that do not support HD Voice (Non-VoLTE) will be impacted. Some of the popular impacted devices include:
    4G LTE smartphones that do not support HD Voice
    Samsung Galaxy S4 or Prior

    from my account on Verizon website:
    Galaxy S3
    IMEI
    ###########
    on my phone:
    SCH-I535
    IMIE
    ###########
    neither show MEID or ESN even though Verizon phones are supposed to be both CDMA and GSM.
    I live in Hawaii, in a cell tower shadow area, so have to use a network extender. phone does not show 4G in upper right of screen area.

    so:
    is my smarty phone a CDMA or GSM?
    and, will it be afffected by the CDMA retirement?
    cheers

    The Verizon Galaxy S3 is a CDMA phone with only LTE band 13. It will stop working when CDMA is turned off end of 2022, maybe earlier as they start shutting down the network. It has no GSM capability, unlike later models.

    First, I see people mentioning all the time you don't want to post your IMEI, etc, on public forums.
    iPhone 12 Pro is my current primary phone. And also have a Galaxy a10e as a backup travel phone.

    As your post indicated, models before the S5 won't work, so aren't VoLTE compatible. And since it works on Verizon, it is obviously CDMA. Some much more modern phones will work on Verizon without CDMA.

    And if you are trying to work a phone until the end of the listed support, you can't assume that something won't happen before then that causes it to be disabled earlier. Though Verizon has extended things a few times.

    They aren't extending it again and just because Dec 31 2022 is the end date doesn't mean it can't be shut off in areas before then. They could shut all all CDMA in my area tomorrow if they wanted too. The OP needs to upgrade already. Even the lowest end Samsung phone is better than this, Even Samsung Galaxy A12 (verizon.com) or Samsung Galaxy A02s (verizon.com) is better than what they have though I wouldn't get either

    Dec 31 2022 seems to be yet another extension to me.

    This date was announced months ago. It's not getting extended further

    All I can say is wait and see. End of 2020 became 2021 then 2022. I’ve been on compatible phone for years so doesn’t affect me.

    Is Verizon Wireless shutting down the 1X/EVDO signal at the end of the year or are they just cutting off access to consumer/MVNO accounts. I think Verizon Wireless has had some business contracts that forced CDMA to stay up but not sure when those agreements expire.

    aloha
    mahalo to everyone that responded.

    on "https://www.wikihow.com/Check-CDMA-or-GSM":
    Check your phone's "About" settings. If you see a MEID or an ESN category, your phone requires CDMA; if you see an IMEI category, your phone is GSM.
    If you see both (e.g., Verizon phones), your phone supports both CDMA and GSM, and may use either network.
    Use the following steps to check your phone's "About" settings
    Android:
    Open the Settings app.
    Tap About phone.
    Tap Status,
    Look for an MEID (or ESN) or IMEI number.

    so, since my phone only shows an IMEI, and not either MEID or ESN, is Wikihow just wrong on this?

    My iPhone 12 Pro Max is active on Verizon’s network via eSIM but it still has an MEID in addition to an IMEI in Settings → General → About.

    The SCH-I535 has CDMA and LTE band 13. It has no GSM capability. It's running on borrowed time. Verizon is providing 3G CDMA and EvDO on an as-is where-is basis with no guarantees of continuing service even now. If something breaks they don't fix it or continue it if a cell site is updated.

    That's correct.. in Chicago the CDMA is just dreadful now. In my house it's full signal LTE/DSS 5G even in the basement - but that's due to a small cell at the end of the block.

    CDMA, indoors is barely "1 bar" and breaks up terribly... outside it's a solid "single bar" and is usable.. but at this point there's simply no reason to keep a CDMA handset.

    2022 now? Boy Verizon can’t can’t stick to a god damn schedule can they. Of course I’m not surprised from a company that’s been “beta testing” IPv6 on their Fios service for 11 years.

    My understanding of the problem is that there are tens of millions of IoT and M2M devices still using 3G. Start with pretty much every truck on the road has a GPS tracking and monitoring system. Those things don't get updated every few years like we do our phones.
