VoLTE (Voice over LTE), also called 4G Calling, lets you make calls over the 4G network for a faster connection and clearer quality, while still using data. It's included on all Zable Mobile plans and switched on by default.
VoLTE works on any handset that supports it. If your calls aren't connecting, here's how to check it's turned on:
On iPhone:
Go to Settings > Mobile Service > Zable > Voice & Data.
Select LTE or 5G.
On Android:
Go to Settings > Network & internet > Zable > Preferred network type.
Select 4G or 5G.
