Trouble with sending MMS, and questions on setting up T-Mobile SIM card with G3

Hello all. Not sure if this is the right place to ask this, but no where else has come close to helping me find an answer to my questions.
----
Wow, that's quite a wall of text below. I'll try to summarize my three questions here:
  • Why won't my phone send MMS? It receives and sends SMS (after some tweaking), and receives and sends calls
  • What network do I choose under the Network operators menu? (RAT : LTE, RAT : WCDMA, or RAT : GSM)
  • Why is my phone's menus seemingly different from the menus in every G3 guide I've seen?
----
I'm having quite a bit of trouble getting my Verizon LG G3 (VS985) to work with my T-Mobile SIM card. Specifically sending text messages. Until a short while ago, I couldn't send any text messages. After playing around in the settings a bit it seems I can now send SMS, but not MMS. I can receive both SMS and MMS, I can receive and send calls, and I can use my data to browse the Internet. I'm utterly confused on how this phone is supposed to be setup and why it isn't working. While in my settings I turned data roaming on, but I tested sending a message after temporarily turning roaming off and it still sent. My APN settings should all be correct (though I'm not sure if there's something special I should set my APN Type as - it's left as "not set" as specified on T-Mobile's documentation).

Another question I have is what network I should choose. When I go deep into the network settings (Settings>More...>Mobile networks>System select> LTE/GSM/UMTS settings>Network operators) and choose "Search networks" it comes up with three T-Mobile networks. They have the following "RAT"s:
  • RAT : LTE
  • RAT : WCDMA
  • RAT : GSM

I'm fairly certain I'm not looking for "WCDMA" but what do I choose between LTE and GSM? As far as my understanding of cellular networks go, my phone should be using a 4G LTE network, but the network (T-Mobile) is also a GSM network. That left me thoroughly confused. Will one of these make my phone work better than the other? Will one let me send MMS?

Questions about T-Mobile network setup and MMS not sending aside, there's one other thing that's bothering me. In almost every troubleshooting guide I've looked up or been walked through, the menus all seem different. I've got software version "VS98535B" (if that's useful for you guys) and Android Version 5.1.1, which I assume is the default or should at least have similar options. However I've encountered two situations where my phone didn't have any type of the option that someone or some guide was trying to show me - once when looking for "WiFi Calling" in my settings (it's not there - "Advanced Calling" is in its steed) and once when looking for some spam setting in my messaging app (also not there). Any thoughts on this? Why does it seem my LG G3 has different menus from every Internet guide's G3?

Sorry to ask so much, but any help will be greatly appreciated!
