Switching on SMS over Wi-Fi on our mobile network
SMS over Wi-Fi means that when your phone is connected to a Wi-Fi network that can access the internet, you’ll still be able to receive SMS messages even if your phone is not in an area where it can connect to our mobile network. We’ve supported Wi-Fi calling on many devices for several years, so you might already be familiar with using Wi-Fi to access your mobile services.
Updates to enable SMS over Wi-Fi on some mobile handsets have gone live overnight and will roll out progressively over the next week. Some of our customers will already see the functionality available on their devices. You can find an up-to-date list of supported devices at our SMS over Wi-Fi page.
To make sure you receive these updates as soon as they’re available for your device, you should make sure your phone is set up to receive automatic updates. If you need a hand, you can find out how to enable automatic updates from Apple and from Samsung.
