AT&T lg g2 using tmobile sim, No 4g/LTE
Hey, I've used xda plenty in the past before but never had to post a question so bear with me.
I bought a att lg g2 and a tmobile sim to go with it. I can only get 3g, no lte. Its very slow. I did some reading and it looks discouraging. I live in south texas.
Is there anyway to turn on the radio bands i need to make 4g/lte work? I saw a thread about how to turn on lte for custom roms. Will that work or not? I think tmobile uses bands 17 19 and 21. There are those bands in the hidden menu on my phone but idk. It looks like some att lg g2s work with tmobile lte and others do not. Thanks for your help.
Ps. Im on another forum where the attitude towards noobs is like xda's so take it easy on me lol.
