GT-i9505 not getting LTE

[Michael Dao]

I haven't been able to find anything on this problem. I bought the GT-i9505 from amazon and for some that don't know, is an unlocked international version of the S4. I checked the bands and it supports T-mobile LTE bands definitely but I'm not receiving any. I also changed to a new SIM card but that hasn't solved it. I also have the LTE option enabled. Maybe if someone can post their APN settings?
Is there anything else I need to know or what I also need to set up so that I can get LTE?

I am a layman, so bear with me. Biut, in my early research, it was common knowledge that the international version, most likely the one with the 8 core processor, will not use 4g/LTE in the US.
If that was the case, I would have paid the extra hundred, and got myself a 8 core processor S4. Samstores sell them, and they qucikly tell you what it will not do.. That is the price you pay for the oct-core, and being able to go international..

Again, I am a newbie and a layman..
