How to Set Up iPhone Data Roaming?

Data roaming lets your iPhone use cellular data on partner networks when you travel. It’s convenient but can be expensive without an international plan.

Enable (or Disable) Data Roaming

1. Go to Settings > Cellular.
2. Tap your line (if you have multiple lines).
3. Tap Cellular Data Options.
4. Toggle Data Roaming on/off.

Travel Checklist

• Ask your carrier about travel passes before turning roaming on.
• Consider adding a local eSIM for cheaper data.
• Enable Low Data Mode to reduce background usage while roaming.
