IPhone – use the UK iPhone 5S in the USA

cellular-carriersinternationalizationiphone

I have an iPhone 5S registered in the United Kingdom with a United Kingdom simcard and number from T-Mobile. I have moved to the USA permanently and cannot call or text any American numbers. I have been told this is because I need to get a US simcard and number. (Please correct if wrong)

I am considering Tracphone as a provider, and asked them if I can use their plan/sim/number in my physical phone from the UK. The answer was

If the phone is an unlocked GSM phone that must operate on 850 and 1900 MHz bands, you can use it.

(Bold emphasis mine). Does my UK-bought 5S fit those criteria?

Yes you can, according to https://support.apple.com/kb/sp685 all iphone 5s models can use GSM/EDGE on the 850 and 1900 bands, so you can make phone calls, text and use EDGE (know as 2G internet)
