I have an armor 22 and it works just fine in the USA. Good signal and this phone is very tough.

The best phone drop it on concrete glass down all the time  never broke

I purchased several of those phones.I actually love the phone,  But the problem is the networks don't necessarily want to support anything to do with these phones. My latest purchase was a 27t pro, After 2 months, the network would not connect, Allow you to send messages or make phone calls. I'm sure this is a good phone for Europe or Asia.But it's not worth the time or effort for the united states

Not sure if this one will get IR nonthermal camera, but I love those special cameras, even more after some abandoned the idea thinking it's anti personal technology, while some photographers use them everyday, now also users of some outdoor phones...
