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.

Not all carriers show whether you're using VoLTE or not. It's just automatic.

If it's not using VoLTE, the phone would drop to 3G or maybe H+ during a call. That's what they used to use for voice calls before VoLTE.

Have you spoken to your wireless provider's support line to make sure their service supports VoLTE on that specific variant?

Is there a "U" at the end of your model number or" U1"?

The phone is definitely capable of VoLTE

If you can find "SIM Card Status", possibly somewhere in "About Phone" > "Status Information", look for the following.

If "IMS Registration Status" is "Registered", and "Mobile voice network type" is "LTE", then you're fine. It's using VoLTE.

they said "you phone does not "seem" to be capable of VoLTE"

No U, nor U1. So why don't I see any VoLTE option on my phone Settings?

Mobile voice network type only says 4G

If I go to Phone Settings and search for "VoLTE" nothing comes up. Is that normal?

Which Mexican provider is this?

Can you go to settings>about phone and show screenshot? Just block your Number, IMEI and serial number
