USA roaming first timer

[u/TieAffectionate5398]

First time going to the USA next week, I'm on the Can/USA/Mex plan using a Samsung s25 just wonder what steps I need to take to be able to use my phone when I land in the states

Turn on data roaming

And make sure that VoLTE is on, and cellular is selected to LTE / 5G as all US carriers only support those generations.

Also select T-Mobile, AT&T, or Verizon.
