Enabling Wi-Fi Calling & Text allows you to make & receive calls and send & receive text messages when you find yourself with a weak or no cell signal.
Wi-Fi Calling & Text is the ability to make and receive calls and send or receive text messages over a Wi-Fi network instead of your usual cellular network.
Typically, calls and text messages go over cell towers, but Wi-Fi Calling & Text goes over the internet. It's an especially handy feature that can keep you connected if you ever find yourself in an area with limited or no cell signal (underground bunker?) but access to Wi-Fi. It still uses your same phone number and you won’t notice a difference in quality.
It could also save you some serious money while traveling. When you “borrow” another carrier’s towers while traveling outside of your carrier’s service area, that’s called roaming - and you have to pay a fee for that. When you’re using Wi-Fi calling, you’re not using towers, so you don’t have to pay any roaming fees - which means more money for souvenirs.
Using data through WiFi doesn’t count towards your monthly allotment.
