Wi-Fi Calling can let you call or text over a Wi-Fi connection, giving you more coverage and options to stay connected.
Using Wi-Fi Calling is easy! Simply connect to an available Wi-Fi network and enable Wi-Fi Calling on your device.
Before you use Wi-Fi Calling, you need to make sure that you set up an e911 address on your account, because your location may not show up automatically to a 911 dispatcher. Learn how to set up your e911 address.
To use Wi-Fi Calling, you need a phone that supports T-Mobile Wi-Fi Calling:
- Wi-Fi Calling is included on most T-Mobile devices. Check the the Devices page to look up yours.
- iPhone 5c, 5s, 6, 6 Plus and newer on iOS 8 or later have Wi-Fi Calling, even if not purchased from T-Mobile.
- Some manufacturers state their devices have T-Mobile Wi-Fi Calling (for example, Nexus 5x, Nexus 6p, Pixel 2).
- Most of these devices work on T-Mobile Wi-Fi Calling without any problems.
- T-Mobile does not test them for compatibility, so we cannot guarantee their service.
- Not available on iPhone 5 or older devices, even with iOS 8 or later.
To set up Wi-Fi Calling on your device, open the Devices page, select your device, and use the help there.
For setting up corporate networks, please check out: Wi-Fi Calling on a corporate network.
Wi-Fi calls placed to other countries are subject to international long distance rates, based on your international calling feature.
|What you're doing||What you're charged on Wi-Fi Calling|
Receiving calls and messages
Making a call to a U.S. number
Sending a message to a U.S. number
If you have an unlimited plan (T-Mobile ONE™ or Simple Choice rate™), all incoming calls, all incoming messages, and all outgoing calls and messages to U.S. phone numbers are free while connected to Wi-Fi Calling.
If you have a plan without unlimited calling, calls made over Wi-Fi Calling count against your plan minutes.
For prepaid lines, calls made over Wi-Fi deduct from the plan bucket, just like regular calls.
Making a call to a non-U.S. number
When in the U.S.
Wi-Fi calls placed to other countries are subject to your plan's long distance charges.
When outside the U.S.
If you have a T-Mobile ONE™ or Simple Choice rate™ rate plan:
If you don't have a T-Mobile ONE or Simple Choice rate plan, Wi-Fi calls to other countries are charged at World Class Calling rates.
|Sending a message to a non-U.S. number|
When outside the U.S.
|Using Internet or data||Nothing. Data used on Wi-Fi doesn't go through T-Mobile, so we don't see it or charge for it.|
Be warned, if your Wi-Fi connection drops for a second or you move outside its range, your call can connect through or transfer to cellular. This may mean unexpected charges if you're in another country. To avoid accidental charges, change your device settings:
- You will lose service when moving out of Wi-Fi range.
- This does not prevent charges from international VPN networks and VPN connections (below).
- Try one the following if your device supports it:
- Set Wi-Fi Calling to handle all calls, which will turn off the device's cellular connection. See device common procedures for Wi-Fi Calling, and look for the Wi-Fi only or Never use Cellular Network setting.
- Set Airplane mode to on, then turn on Wi-Fi and Wi-Fi Calling.
- Turn off roaming data in device settings. For more information, see International roaming services. (May still allow some types of data, as designed by the device manufacturer.)
Billing for VPN connections
A Virtual Private Network (VPN) connects you securely to a network of other computers. While connected, your Internet usage goes through that network, wherever it's located.
- You may connect to a Wi-Fi network that uses VPN, or you may set up VPN on your device (for work or privacy, for example).
- If that VPN network routes through another country, then your device connects to Wi-Fi Calling from that other country. So even if you're in the U.S. or a Simple Global country, you may be charged World Class rates.
- You'll receive a standard Welcome SMS when VPN connects to another country through your device, and you must enable data by dialing #RON#.
