Please help me w/Samsung Galaxy S6 Duos

[musique101]

So I bought this Samsung Galaxy S6 Duos (Unlocked) [SM-G920FD] from Swappa but can't seem to get it work with T-Mobile at all! I'm hardly getting any bars plus network keeps dropping off. Funny thing is I live in a T-Mo zone, my other phones (running on T-Mo) work without any issues. No Problem with LTE either.

I'm super frustrated and donno what to do anymore.

What apn setting do I need to use? I will really appreciate it if anyone can kindly help me out with detailed instructions, since I'm a such a dumbo!

Thanks in advance

Duos g920FD is same geographical version as international g920F (except it is single SIM), same 3g and LTE freqs.

There is a T - Mobile version for s6 (g920T), only single sim, there is not duos t - mobile version.

It means probably your carrier is using 3G 1700MHz freq on your zone, the only additional frequency that g920T has and g920F/FD hasn't. Both versions have same LTE freqs except F/FD versions has 3 more LTE frequencies available, because this you have not problems with LTE.

Check with your carrier if they are using 1700MHz 3G band and if so, sorry, you should change any of your carrier or your phone, or force GSM connections. Or maybe you can also configure your duos s6 using a non T-Mobile SIM for data 3G/LTE, and your T-moblie SIM as 2G (GSM) only voice/SMS.
