Learn about 4G Calling

4G Calling means that when you make or receive a phone call, your phone will stay on 4G so your internet doesn't slow down. That means you can use data at 4G speeds even when you're on a call. Sounds simple, but you'd be surprised how few mobile providers will let you do this.
