VoLTE Option Missing. US unlocked phone with Mexican network provider

[abccollins]

Hi, I bought an S22 unlocked phone in the US. I am now in Mexico using a Mexican SIM card from a Mexican provider. I am able to make calls (not Wi-Fi calls) and surf the internet. My provider tells me that the SIM card supports VoLTE; however, I do not see any VoLTE option on my phone (Settings > Connections > Mobile Networks > Network mode). Is there a way to fix this? I would appreciate any help.

What's the exact model number of the phone? You can find it in Settings>About Phone.

There are a few different VoLTE technologies, so it's possible that your provider is using one that's not supported by the S22. https://en.wikipedia.org/wiki/Voice... calling with 2G and,do not have call service.
