T-Mobile 4G LTE Bands Not Working on Exynos Galaxy S9/S9+!

It seems like Samsung has made some changes to the international Exynos Galaxy S9/S9+ and not all T-Mobile 4G LTE bands are supported this year unlike previous Galaxy phones. AT&T is not affected but if you are on T-Mobile, just know you may get stuck on HSPA+ most of the time if you buy the international Exynos Galaxy S9/S9+ models.

Update: The issue has been fully fixed after doing a software update, it was an early bug that is fixed easily with software update.  4G LTE works great now and picking up 4G+ signals also, please disregard this post thanks.

Affected models:
SM-G960F, SM-G960FD, SM-G960F/DS
SM-G965F, SM-G965FD, SM-G965F/DS

A good alternative is any previous Galaxy international models like the Galaxy Note 8, S8, S8 Plus, S7, and S7 Edge, they all support T-Mobile 4G bands fine.

    Hey, so I have been watching your videos on the exynos S9+ and I was thinking about getting one. Have you managed to figure out the connection to t mobile? If you could let me know if it fixed itself or what you did to fix it that would be much appreciated. Also I have read that the 4G connection speeds are throttled even by those that did get 4G, has this been addressed?

      Yes 4G LTE works flawless, no worries here, but make sure you do the software update which fixes the issue.

        Ok, sounds great. You aren’t having any issues with the missing Band 71?

        • Max Lee says:

          I don’t think Band 71 is available in many places but I do get 4G+ pretty much everywhere here.

            I’d like to see your connection speeds while on 4G. Guess I need to decide on color, it is a shame the red variant is only in China and with Snapdragon :/

    I did the software update but I don’t see LTE as an option in network mode. I only see 4g/3g/2g and I am not getting LTE. Any help would be appreciated
