Carrier billing is a useful feature for those who wish to purchase content from the Windows Phone Store and be charged through their operator. Three UK has added support for Microsoft's mobile platform.
The company confirmed the addition of carrier billing on Twitter earlier today.
@DanOffTheRadio Hi Dan, yep, this will be charged to your bill. It's a new option we've introduced. >DD— ThreeUKSupport (@ThreeUKSupport) April 15, 2015
Check out the changes on the Windows Phone Store, and be sure to let us know how you're getting on with carrier billing in general (should you be using the feature).
Thanks, Dan M., for the heads up!
