Yes!!!
You might need the correct APN set up for data.
But your new phone are running Android 7.1.1, it should be plug and play
and no special APN setting needed.
Your new phone will also show up H+ or H++ on AT&T network (AKA 3G or 4G in North America.)
I am using unlocked phones from Asia.........they all show up as H++ when I'm using mobile data.

It has no LTE bands for the US, but I has 3G, so calls and text will work fine once APN is programmed.
This is not a brand we recommend because it doesn’t get LTE.

Another phone that will show up H+ or H++ on AT&T network
Will be a good phone to use in Asia
with working 4G LTE & dual sim, Android 7.1.1
16 MP camera front and back.
