Will the IPhone 14 work in Dominican Republic if I live there and there is no SIM card now?

All 14x iPhones sold for the US market will eSIM ONLY.

While these “US” phones WILL work in DR with their eSIMS (via their carrier’s international roaming agreement) there as-yet are not any “local in DR” eSIM carriers.

The 14s sold for your region will be fitted w/ sSIM + nanoSIM.

I’m confinemt that they will.

Apple often “prods” technological change, IMO this is just one more instance.

FYI, eSIMS have been running here on the US for about four years.
