A few minutes in the app before you leave
International roaming is usually just a matter of picking your destination and dates in the carrier app. Leaving data switched on abroad without an active plan risks a steep per-megabyte charge, so it's worth confirming before takeoff.
Prepare for a lost phone while traveling too
Losing a phone is more common while traveling than at home, so it's worth turning on a device-finding feature ahead of time in case something goes missing during the trip.
Frequently Asked Questions
Does my home plan get affected once I add a roaming plan?
No -- your regular home plan usually stays active and the roaming plan is layered on top for the trip. It typically ends automatically when your set period is over, and you go back to your normal plan.
What if I'm visiting more than one country?
Many roaming plans are set up per country, so you may need to set up a separate plan for each destination, or check whether your carrier offers a multi-country option that covers your whole itinerary.
