4G Calling (known elsewhere as VoLTE) is a free iD service that lets you make and take calls over our 4G network.
We know that indoor blackspots can stop you getting connected. With 4G Calling, that’s not a problem - it gives you clearer calls, in more places than ever before.
4G Calling works across our 4G network. Check your coverage here.
4G Calling currently works on iPhone SE, iPhone 6, iPhone 6 Plus, iPhone 6s, iPhone 6s Plus, iPhone 7, iPhone 7 Plus, iPhone 8, iPhone 8 Plus, iPhone X, Huawei P8 Lite, Huawei P10, Huawei P10 Lite and Huawei P10 Plus.
Update your phone’s software (if needed) and accept the latest carrier settings (for iPhone users). Then 4G Calling is good to go!*
* iPhone users will have to install the latest software (iOs 10.3)
4G Calling uses 4G to smash through indoor blackspots, so you'll be able to make phone calls in more places.
4G Calling calls are clearer than a typical mobile phone call. You'll notice a real improvement in voice quality.
4G Calling can conntect your 4G calls up to twice as fast as traditional methods that use 2G wireless networks.
4G Calling means your phone doesn't have to switch to 3G/2G to make or take a call - saving your precious power.
There's no difference - it's exactly the same thing. We just thing that '4G Calling' gives you a better idea of what it's all about.
Yes. 4G calls are much better quality than normal calls made over 2G and 3G connections. This is because more data can be transferred over 4G (up to three times as much as 3G, and up to six times as much as 2G). You'll find it easier to hear what the other person is saying, and their tone of voice will be richer and clearer too.
To get 4G calling on your compatible iPhone, you need to make sure your software is up to date. You can do this by connection to Wi-Fi, then going into 'Settings', 'General', 'Software Update'. If a new software version is available, you'll be able to tap 'Download and install'.
We recommend that you backup your iPhone's memory before you do any software updates - just to make sure everything's safe.
We're currently working with different manufacturers to launch 4G Calling on their smartphones. Keep an eye on this page, because we'll update it as each new handset become compatible.
Coming soon: Samsung S7, S7 Edge and S8.
