How to Choose the Right SIM for Your Trip
Three questions help narrow the decision quickly.
How long are you traveling?
Under 3 days: a carrier roaming pass is fine. 3 to 7 days: a local SIM or regional eSIM wins on cost. 7 days or more: a local SIM with a generous data plan is almost always the cheapest and best-performing option.
How many countries are you visiting?
One country: buy a local SIM on arrival. Two to four countries in the same region: a regional eSIM saves SIM swapping. Five or more countries across different regions: a global eSIM or a new local SIM per region.
Do you need to keep your home phone number active?
Yes: buy a local SIM and use dual-SIM mode on your phone, keeping your home SIM active for calls. No: use the local SIM or eSIM for everything, which is simpler and avoids any roaming charges on the home line.
Always confirm your phone is unlocked before purchasing a local SIM or eSIM. A locked phone will not accept a foreign carrier's profile regardless of which SIM you buy. Check by inserting a friend's SIM or contacting your carrier.
