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.
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.
