Anyone able to do dual VoLTE when Tmo is not data sim and Verizon is?

I have Tmo and Verizon sim in the non-TMO GM1917 . I want to use Verizon SIM for Data. When i do this, Tmo drops to UMTS for calls. If I leave Tmo as data sim, both lines do VoLTE.
I don't really want to randomly mess with different dialer settings under *#*#4636#*#* - anyone have any luck with both Verizon And Tmo as dual sim doing VoLTE on both lines while keeping Verizon for data?
If not, do we think that Android 10 will make a difference?
Another reason I want VoLTE on the Tmo SIM is that is what controls VoWifi - no VoLTE, no option for VoWifi.

Dual VOLTE ? Poco X3

Hi everyone, I can't simultaneously activate the Volte on both sim cards with the code*#*#86583#*#* it only activates the volte on sim 1 or when I do it again in the dialer only for sim 2
Thank you for your help.
Am I the only one who wants double VOLTE on my phone?
I'm right here with you. Better yet I've noticed I dont actually get Dual 4G signals at all which is why it probably doesnt work for me? How about you, do you get dual 4g signal?

VoWiFi (Wifi Calling) and VoLTE not working with Mint with Xiaomi POCO X3 NFC
VoLTE and VoWiFi/WLAN does not work on Mint Mobile (t-mobile USA mvno), when is enable you cannot make any calls!!! also VoWiFi (WiFi Calling is enable in my account I tested with another phone) does not work I even enter the codes to disable the carrier check VoLTE *#*#86583#*#* and VoWiFi/WLAN *#*#869434#*#* I even went to configurations with the code *#*#4636#*#* and I was unable to switch to ON or OFF
VoLTE and VoWiFi/WLAN works fine on my other Xiaomi Redmi Note 8 Pro but why is not working on the POCO X3 NFC

Did you tried to make a call from sim1 and from sim2 and VoLTE doesn't work? Or you wanna get the VoLTE symbol near phone signal for both sims in statusbar? If this last one you want, it makes no sens, because you can't make 2 calls (using sim1 and sim2) simultaneously anyway My guess is that VoLTE automatically applies to the sim you use to make a call (I'm guessing because I use only 1 sim in my phone)

daul sim with 5g not working

Is there any rom or way to enable daul sim with one of the both sim is 5g??,. Because once u have 5g sim the other sim is turned off

LineageOS (microG) e-sim support => dual sim?

Does the original ROM of the pixel 2 support dual sim functionality with the esim?
Does LOS support esim function at all? I cannot find something in settings, but have never used esim before. And does that mean I can use the usual sim and esim at the same time, so a real dual sim function?
