Introducing Wi-Fi and 4G calling

Our network has two new features for all our customers to use: Wi-Fi and 4G calling! Find out what they are and how you can use them to stay connected in even more locations. 

What is Wi-Fi calling?

Wi-Fi calling allows you to send and receive text messages or phone calls completely through a Wi-Fi connection. This means that you can still communicate with other people even if you are in an area without signal.


What is 4G calling?

Also referred to as “Voice over LTE”, 4G calling allows you to make mobile phone calls using your data. Calls like this are often clearer, with high quality audio making it feel as if the caller is beside you. When it’s turned on, your phone will automatically move between Wi-Fi and your 4G data to keep the call connected if you experience spots of internet failure (like underground). 


How do I activate these new features?

Wi-Fi calling

Activating Wi-Fi calling is quick and simple, and once you’ve turned it on, it will connect automatically in Wi-Fi areas without signal. So if you’re on a phone call and suddenly lose signal or enter a poor signal area, your device will automatically transfer to Wi-Fi calling so you stay connected. 

All you need to do is locate Wi-Fi calling in your phone’s settings and ensure it’s switched on. 


4G calling

Like Wi-Fi calling, you need to find the 4G calling option in your phone’s settings and ensure it’s switched on, so your mobile can bounce between these two types of calls, so you never lose connection. 

If you can’t find this setting or you’re unsure, simply check your handset manufacture guide to see if your model is compatible.


Does it cost more money to use?

You won’t incur any extra charges for using either Wi-Fi or 4G calling. The feature is free to use and is available to all customers on our new network. Wi-Fi calls and texts will be treated just like regular calls and texts - standard rates apply. Similarly, when making a call over 4G, our standard data rates apply.

You can browse our great value monthly bundles and take advantage of unlimited minutes and texts. Bundles start from £4 and come with a varying amount of data.


Can all phones use these features?

Wi-Fi calling

Unfortunately, not all phones are compatible with this feature. Although a number of models from the likes of Apple, Samsung, and Huawei all support Wi-Fi calling, if you bought your phone from another network or 3rd party, we can’t guarantee they will work. Check your phone’s settings or user manual to see if it’s compatible. If there is no option for Wi-Fi calling, try updating your operating system to the latest version. 


4G calling

Only models which are compatible with 4G calling (or have access to 4G data) will be able to take advantage of this feature. If you can’t find 4G calling in your settings, you can ask the manufacturer if your specific model is compatible. You may be able to find this information out on their website.
