11 Best International Roaming Plans Compared for 2025

Final pick and quick checklist before you go

Pick the roaming option that matches your trip length, data appetite, and tolerance for setup. If you’re on a short business trip and want to keep your US number, a carrier day pass or premium unlimited plan is the simplest path. If you need lots of data for a week or two, an eSIM from Holafly, Airalo, or GigSky can be fast and convenient. For the lowest per‑GB price while staying longer, buy a local prepaid SIM at the airport or local shop. For the best balance, use the hybrid approach: temporary eSIM quick start, then local SIM for long stays, with your home SIM on standby via dual SIM or call apps. Before you leave: (1) Check your phone is unlocked and eSIM‑compatible; (2) Confirm country coverage and roaming rules on the provider page; (3) Note any daily fees or throttles; (4) Keep screenshots of activation QR codes and APN settings; (5) Confirm currency conversions and possible taxes. A final practical note—if your dadi taught you to keep an extra handkerchief for long train rides, pack a small travel checklist electronically: backup maps, offline tickets, and at least one contact method using your active number. That will keep your trip connected and calm. Safe travels and may your calls home be easy and your data fast.
