Switching while on calls

We're glad you asked. The big guys like to be in control, so it’s not possible to do a “hot hand-off” from one network to another (yet). But, our use of VoIP (voice over internet protocol) means that when there's a quality network available and we can perform the switch quickly, you may just experience a temporary pause in the call. The same is true on apps such as Zoom, WhatsApp, Skype or FaceTime.

Our recommendation? If your connection weakens, you can end the call. Within a minute, we'll be on the hunt for a better signal or you can use the in-app on-demand network switching button. And, if you do lose connection completely, don't worry—we'll automatically start searching for the best available network to get you back online fast. Our goal is that you never have to say “can you hear me now?”
