Why does my phone switch to 4G when on a call?

Cause: The VoLTE function is disabled, resulting in the 4G network not supporting phone calls and the phone automatically switching to the 2G/3G network during calls, and going back to the 4G network after the call is ended.

Why does my LTE disappear when I call?

If you’re not on the move and see LTE disappear, there may be something else going on. It could be a phone fault, software fault or even a network fault. If your data speed remains the same, it could be a network issue or upgrade. If your data speed drops, it could be a network outage or phone fault.

Does 4G (LTE) support voice calls?

4G (LTE) doesn’t support voice calls in the simplest implementation, it is only a data transfer system; your phone has to swap to a 2G or 3G cell to make a voice call using a technical process called “Circuit Switched Fallback’” (or CSFB). Currently networks are implementing a data network based voice solution called “Voice over LTE” (or VoLTE).

How do I make a phone call over 4G?

In order to make a phone call over 4G your carrier and device must support a form of Voice-over-LTE since the architecture of a 4G network is different than a 3G network (packet switched vs circuit switched). If the requirement is not met, your carrier will switch to the older circuit switched network (3G or 2G) in order to place the call.
