WiFi Calling + eSIM = zero roaming charges
WiFi Calling handles voice calls for free. A travel eSIM handles data at local prices. Together, they eliminate every form of roaming charge your carrier can bill you for.
- Voice calls: $1.70-3.00/min
- Texts: $0.50/text
- 10-min call home: $17-30
- Voice calls: $0 (domestic rate)
- Texts: $0 (domestic rate)
- 10-min call home: $0
VoIP alternatives: WhatsApp, FaceTime, Skype
If your carrier does not support WiFi Calling, use a VoIP app instead. WhatsApp voice and video calls, FaceTime Audio, and Skype all work over WiFi or eSIM data at minimal cost (about 1 MB per minute for voice, 5-10 MB per minute for video).
The drawback: both parties need the app installed. For calling regular phone numbers (restaurants, hotels, emergency services), WiFi Calling is the better option because it uses your real phone number and works with any phone number worldwide.

WiFi Calling questions, answered
Does WiFi Calling work abroad?
Yes. WiFi Calling works anywhere you have a WiFi connection. Your call routes over the internet instead of the cellular network, so no roaming charges apply. Most US and UK carriers support WiFi Calling internationally.
Is WiFi Calling free when traveling?
Calls made via WiFi Calling are billed as if you were at home. If your plan includes unlimited domestic calls, WiFi Calling abroad is effectively free for calls to domestic numbers. International numbers may still incur long-distance charges depending on your plan.
Do I need to enable WiFi Calling before I travel?
Yes. Enable WiFi Calling in your phone settings before departure. Some carriers require you to register your emergency address first. Test it on your home WiFi to confirm it works before your trip.
Does WiFi Calling use data from my eSIM?

What is the difference between WiFi Calling and WhatsApp calls?
