AT&T LTE requires a sim, and AT&T GSM requires a sim. Obviously phones have to support both when there isn't LTE available, so how does it work? Do they have two sims?
Got a tip for us?

Will AT&Ts 4g LTE frequencies penetrate buildings better? Thats pretty much the only reason I left them after 9yrs. Thinking of going back though...
I think you missed my question.
GSM requires a sim. LTE requires a sim.
Are they combined into one? or do GSM/LTE phones have two sims or what?
They have one SIM. LTE, 3G, and 2G GSM will all utilize the same SIM on a single phone.
Saying it's "combined" isn't really accurate, because there's nothing to combine. It's just a single SIM like it's always been, and all three interfaces just use the same one.

Ahh alright. I've been with Verizon forever so never had to use sims. Nice to know thanks!
Also, LTE is only used for data. HSPA+ is still used for voice. In fact, you lose LTE data when you're on a call as it drops back to HSPA+. One reason why AT&T LTE is better than Verizon despite the coverage. VoLTE is coming which will run voice over LTE as well.
