How do I set up WiFi calling and roaming to make calls and texts abroad using WiFi or a travel SIM?

To enable calls and texts from your World Mobile US number while on WiFi or using a travel data SIM abroad:

1. Enable WiFi Calling & Roaming
   - iPhone: Go to Settings > Phone > Wi-Fi Calling→ Turn on Wi-Fi Calling on This iPhone. Then enable Calls on Other Devices if needed.  
   - Android: Go to Phone app > Settings > Calls > Wi-Fi Calling → Turn on Wi-Fi Calling. Also enable Calling over mobile data when Wi-Fi is unavailable* (if supported).

2. Add a US Emergency Address 
   - Required for compliance. In WiFi Calling settings, enter a valid US address (e.g., your home or billing address). This ensures emergency services can locate you if needed.

3. Ensure Internet Connectivity  
   - Connect to WiFi, or  
   - Insert a travel data SIM/eSIM in your second SIM slot for mobile data.

4. Use Your Phone Normally
   Once connected to the internet, make and receive calls and texts exactly as you would in the US—your World Mobile number remains active globally.

> Note: WiFi calling uses data, so ensure your internet source (WiFi or travel SIM) has sufficient data. No additional apps are required.
