    Lol. The phone just got the September security update from T-Mobile.

    Once a phone is AT&T branded, it's stuck at AT&T branded. Although, I thought that meant it always showed the AT&T logo on start up. Never known one to change it's logo on start up.
    it just unlock the phone for use on other networks besides AT&T
    unbranded phones are probably what your looking for.

    Generally speaking, what you're saying is true with most network-branded phones.

    However, the Samsungs (I believe starting with the S8) can actually flash different carrier firmware onto the device such as AT&T, T-Mobile, Cricket, etc. See a guide on how to do it here: https://appuals.com/carrier-switch-f...s8-snapdragon/

    My theory is that an either factory unlocked or network unlocked S8 or later Samsung will flash its firmware to the correct carrier upon inserting the sim and booting the device. I believe the carrier variant is signified by the splash screen.

    My S8 had the same behavior of showing a t-mobile splash screen when I network unlocked it from Cricket a few months ago. After I put the Cricket sim back into the device, its splash screen reverted to Cricket with the appropriate apps/features.

    I didn't know all of that, thanks for the info.

    But kind of goes back to my earlier point, the Android eco-system is just way too complicated. It really needs to be simplified from a security standpoint.

    I agree completely! Way too complicated!

    If you go factory unlocked, you might be missing out on some of the carrier's features like VoLTE or Wifi Calling. But, you'll have carrier portability and [hopefully] timely updates.

    If you go carrier-branded for a discounted phone or access to the extra features, you might not get timely software or security updates (or worse, be completely abandoned). Also, you might have hoops to jump through to unlock it from the original network or get software security updates should you decide to go with a new carrier.

    Good to hear! The S8 and newer phones seem to allow the firmware to be reflashed to the SIM card carrier.

    Good to know this is true. At least Samsung is getting smarter with the firmware and updates.

    AT&T is the ONLY carrier that forces you to have an active AT&T SIM to get updates. I have Sprint Samsung Note 4's, S6's, etc., that get Sprint Android updates regardless of service. Same with T-mobile as well, and I believe Verizon as well (none of my Verizon MVNO friends complain about this, and I have only iPhone with Verizon).

    AT&T is positively EVIL in requiring an active AT&T SIM just to get Android security updates.

    Thanks to all who have answered so far. The next questions are:

    - The phone did not reprogram itself to Cricket when I popped that SIM in and restarted. Is there a way to force it? It seems the switch to T-Mobile happened because I had the T-Mobile SIM in the phone and AT&T had issued the unlock code.
    - is it worth it to try and get the phone to reprogram itself to Cricket? Or am I better off keeping it as T-Mobile? How good is Cricket at issuing timely updates?
    - If I keep it as T-Mobile, are there any drawbacks? I assume that the phone has access to all the bands and it is not limited by the firmware installed? I won’t have connectivity issues because it’s not using the AT&T bands?

    Try downloading the firmware from Samsung's website as an alternative: https://www.samsung.com/us/support/downloads/

    Interesting. It seems my theory regarding auto-update to the appropriate carrier firmware is debunked.

    I'd try to get it on the Cricket firmware if you're able. I've got an S8, and the HD Voice and Wifi Calling are pretty helpful features for me personally. I don't know if you'll get them running T-Mobile firmware, or if they matter to you at all. Unfortunately, the Cricket S8 isn't eligible for the $10 hotspot add-on option.

    My S8 is running 8.0 Oreo and is on the October 2018 security patch. It seems to get regular updates.

    HD Voice and WiFi Calling are not important to me. I am able to run Hotspot straight from the phone. And I was able to do so before I unlocked it from AT&T and reflashed it to T-Mobile. I’m pretty surprised at that.

    No. Xda and research. You'll need a decent understanding to do it anyway.
