Still Deciding? What Will I Lose?

Does switching platforms affect physical-SIM users and travel?

Travelers using physical SIMs need to check the destination phone’s SIM slot, eSIM support, carrier lock and roaming terms. iPhone Duo is eSIM-only worldwide; other iPhone and Android models differ. Confirm your home and travel plans before you rely on a physical SIM swap.

What to do

  1. Check the exact device SKU and carrier lock status.
