How do I activate VoLTE on my iPhone?

Ensure you have updated your phone to the latest software version. 

After restarting the phone, please follow the below steps to activate VoLTE: 

  1. Open the Settings app and choose Mobile Data
  2. Choose Mobile Data Options
  3. Choose Voice & Data
  4. Choose 4G and activate VoLTE

Keep in mind that the steps may vary depending on phone model, double SIM-cards etc.
iPhone 12 does not have a VoLTE setting, it is always active. 

How do I know VoLTE works? 

If you're calling with VoLTE it means that you're using the 4G (LTE) network during the call, instead of 2G or 3G. Because of this, you should be able to see the 4G symbol on your phone while being in a call. You should also be able to use your mobile data during the call. 

Keep in mind that the phone automatically switches between 2G/3G and 4G (LTE) depending on your current connection to each network.

To get full call waiting functionality you'll need to activate it in the Telavox mobile app. This is done in the Telavox app below Settings > General > Call waiting
