My Galaxy S5 Sm-G900F is stuck on HSPA+ And Has Tmobile LTE bands

[AC Question]

Hey Guys I have a galaxy s5 internationally unlocked version! It should support 4G LTE since it has Tmobiles bands. I set it to LTE/WCDMA/GSM since that was the only option that has LTE in it but I have never been able to connect to LTE. I'm usually alway on EDGE or HSPA or HSPA+. I wanna be able to connect to 4G or 4G LTE. Can you guys help me fix this problem? I'm kinda a noob at this so please explain.! Thanks!
