Use Verizon LG G3 on AT&T - G3 Q&A, Help & Troubleshooting

My Nexus 5 phone broke but I have a Verizon LG G3 laying around the house. I rooted it and flashed TWRP on it. How can I get the AT&T LTE bands unlocked? Is there any ROM that can convert the Verizon model into a International Model, or at least unlock all of the frequency bands? Right now only HSPA works.
Thank in advance for your help.

Get AT&T LTE working on VS985 Verizon G3

My nexus 5 died and i need a new phone. I have a Verizon LG G3 that I can use but I cannot get it to see LTE, only HSPA on AT&T.
I did some research and it seems I need to unlock carrier frequencies, or something similar.
SInce the phone has TWRP and is unlocked, is there any specific ROM I can flash to unlock all carrier frequencies? I really liked that with my Nexus nearly anywhere I went in the world I could just buy a sim, pop it in, and go. No hassle.
Thanks for your help in advance.

[Q] LG G4 (F500-L) on T-mobile?

I currently have a Korean variant (F500-L). I have seen a couple of these for sale on swappa and both posts say that this phone will work with T-mobile LTE. However, when I've popped in my SIM, I only get 3G. Does anyone else have any experience with this variant on T-mobile? If you were able to get it to work on LTE, how did you do it?
Enter APN settings for T-Mobile. Google that. Just popping in the sim won't give lte.
i have the same issue.. the APN settings seem to be correct.. but it only shows 3G. Model is F500-L
same here i need help too mine is a f500s lg g4 skt version thanks
Far as I know, phone must support LTE Band 2 and 4 to work on T-Mobile 4G network.
But F500(Korean ver. of G4) doesn't support LTE Band 2 and 4. It supports LTE band 1,3,5 and 7. Therefore a phone will only work under 3G network.

T-Mobile on verizon lg g4?

So i have a iphone 6 plus and someone offered me a verizon unlocked lg g4. Tmobile is my carrier and i understand that the g4 is unlocked but i was wondering how would tmobile be like on the g4? Will LTE function normally ? Thanks
edit: nevermind was wrong
The Verizon G4 supports bands 2/4/13. Most of T-Mobile uses band 4 for LTE, and on recent 2G > LTE converted sites they typically use band 2, so yes I'd say it would work well. The one they are missing is band 12, so you won't get any of T-Mobile's low-band spectrum.
You will likely also get an invalid SIM warning on your phone, since it's not a Verizon SIM.
My Tmobile branded Iphone doesn't have band 12 either so will my service be the exact as I have it on my crapple 6 plus ?
Should be.

Verizon G4 to ATT without modding?

I have a unmodded Verizon LG G4 with Marshmallow 6.0. What would happen if I just took the sim card out of my ATT Moto X and put it in the G4?
Would I get anything close to LTE speeds? What wouldn't work?
If I rooted the V-G4, what would that help to do? It it necessary?
thx.
Well the phone is unlocked for GSM, so you should be able to use it on ATT. Just pop the sim and see.
In future, just check this website: www.willmyphonework.net
It works after inputting the ATT codes, but gets the "H" band instead of LTE.
