About this app

No signal, no problem. You’re covered with VoWiFi(Wi-Fi Calling) from participating carriers. With this feature, you can make calls and send messages over a Wi-Fi connection when cell service isn't available. Now you’ll never be denied by a weak signal again.

What is VoWiFi(Wi-Fi Calling)?
It is regular calling on your cellphone, except your carrier routes the call over an available WiFi network instead of its cellular network. When you call, your phone automatically selects the best network — cellular or WiFi — you don't need to do anything.

How much does VoWiFi(Wi-Fi Calling) cost?
It doesn't cost anything extra. Carriers treat your WiFi calls as though you were making a regular cellular call from the U.S. So whatever rates and fees apply to your regular cellular calls will also apply to your WiFi calls, including deducting call minute from your monthly allotment if you don't have an unlimited plan.

Ratings and reviews

S22 Ultra US Cellular WORKING SMS. The phone had the option but just wouldn't work. My S21 did the same stupid thing. A reddit thread mentioned this program. Boom. Snap a doodle. Not only is it working but it seems to be really trying to connect to the (distant) phone tower as well. Whereas before it was just the circle with the line through it. Thank you thank you thank you. All I really needed was the texting to go through. Immediately WORKED!

Welp. 3 stars I took a chance. worse that could happen is it doesn't work. Best that could happen is it does. After trying every thing possible that was suggested online for wi-fi calling I found this app. It worked. so it gets five stars. what do you have to loose when you have tried everything else suggested.

Worked great at first, I was able to turn on wifi calling even when I had no cell signal at all and it worked! Now wifi calling is still enabled but it won't connect, I've tried everything and still no joy. Not sure why it stopped working all of a sudden but it's useless now.
