Simple ways to boost your service

No one likes to be without a cell signal. As a T-Mobile customer, you have solutions available to help strengthen your connection and get the most out of our network.

Bring 4G LTE home with a signal booster

A signal booster works to strengthen the coverage in your house. It’s easy to set up and the only cost is a $25 deposit. All you need is at least a 3G-capable device and one bar of service.

Talk and text via Wi-Fi

Every Wi-Fi connection works like a T-Mobile tower. Connect your phone to a network and you can make calls, send texts, and surf the web. No apps, logins, or extra costs required.

Using Wi-Fi Calling is easy! Simply connect to an available Wi-Fi network and enable Wi-Fi Calling on your device.

Setting up Wi-Fi Calling

To use Wi-Fi Calling, you need a supported T-Mobile Wi-Fi Calling-capable device. For information about setting up Wi-Fi Calling on your device, check out the How-to guides for your device on the Device tutorials page.


Before you use Wi-Fi Calling

You will need to set up your e911 address, as your location may not be automatically available to the dispatcher if you need to call 911. Learn how to set up your e911 address.


International calls and messages to the U.S.

With unlimited plans like T-Mobile ONE™ and Simple Choice™, all incoming calls and messages as well as outgoing calls or messages to U.S. numbers over Wi-Fi Calling are free. However, to avoid incurring data roaming charges, make sure that you disable data roaming when traveling internationally.

If you have a plan that doesn't offer unlimited calling, calls made over Wi-Fi Calling count against your plan minutes. For Pay In Advance prepaid lines, calls made over Wi-Fi deduct from the plan bucket just like regular calls
