World Mobile US plans provide coverage within the United States and do not include traditional cellular roaming on foreign networks except for Canada.
You can however, make or receive voice calls or SMS over cellular data when traveling abroad with additional configuration.
Your World Mobile eSIM allows you to make and receive voice calls and SMS using your same U.S. number from anywhere in the world, provided your phone has an active internet connection. This can be achieved via:
- WiFi or
- A secondary SIM slot with a local or travel data SIM/eSIM.
This data-based connectivity enables global "roaming" without incurring World Mobile international roaming fees.
Recommended: Purchase a Travel eSIM to maintain internet access while abroad. Ensure your device supports dual-SIM functionality for seamless use abroad.
