Do be careful, your choices are very limited. All the carriers in the US, except TMobile today, have a whitelist of devices. Even if you make your own phone or buy an awesome phone from out of market, it won’t work.
Technically, there is no reason it won’t work. But the carriers block it from registering on the network unless roaming. Our non-American devices have been kicked off every network now except TMobile.
So your choice is really just the small list of devices they choose to support and 75% are the same phone. Samsung whatever with some various sized screen and various sized storage. Or Apple iWhatever.
They make your life hell with a non-standard carrier phone. And yes I’ve been buying out of region phones for 20 years now, even back with Windows Mobile and Palm devices with 2G text based web. Every year it gets harder and harder.
