What is 4G Calling?

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.

Improved coverage

4G Calling uses 4G to smash through indoor blackspots, so you'll be able to make phone calls in more places.

Superior call quality

4G Calling calls are clearer than a typical mobile phone call. You'll notice a real improvement in voice quality.

Faster connectivity

4G Calling can conntect your 4G calls up to twice as fast as traditional methods that use 2G wireless networks.


There's no difference - it's exactly the same thing. We just think 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.
