[Q] Enable VoLTE (Carrier VOLTE Update)

ROM: Resurrection Remix Nougat Final
Carrier: Idea 4G, India
Device: i9195
I have flashed magisk modules VoLTE and VoWIFI enabler. Within the telephony hidden menu (*#*#4636#*#* in dialer, then in the phone information) it shows VoLTE provisioning is enabled. But still can't get incoming or outgoing calls on LTE only mode. The phone call gets disconnected automatically. Is there any way to get VoLTE? Does it require any carrier specific OTA update? The sim card supports calls in other VoLTE phones.

[Volte] Enable volte in ZUI v4.0.186 & v4.0.199

In ZUI v4.0.186 & v4.0.199 volte option is hidden, it might have been intentional, on accessing the volte menu you will see why there is an option to enable volte on both sim and interresting enough controls used, allow for both sim to have volte at same the time. When I tried using two volte sim didn't get the expected result but did get jio volte on my second sim slot with no signal on the first one. Its very buggy, so used volte as you were using before, on first sim slot.
Just install the app below to access volte menu.

Cricket VoLTE and Wifi Calling on U1 Firmware

I recently purchased a S9 from Cricket during their last promotion. I'd like to flash U1 on it as it's what I've used with my S8. Does anyone know if VoLTE and Wifi Calling work when using U1 firmware on Cricket. I remember reading somewhere that Cricket only supported VoLTE on their phones bought through them and the restriction was IMEI based. So I feel good about that working, but I'm unsure about Wifi calling.
Hi, did you get anywhere with this? I have a U1 S9 and I don't want to flash the carrier branded firmware but I've heard VoLTE will work on the U1 (unbranded) S9s on Cricket (and AT&T)...

Question OOS 11.2.5.5BA/NA 5G/Dual Sim?

Hi all, I think I already know the answer to my question.... I just want to be 100% sure as my searches are not quite revealing my answer.
Like many...when I received my NA OP9Pro I was disappointed to notice it wasn't dual SIM. Sent it back and still waiting for a refund for almost 2 months now. (That's a frustration with OP in itself...makes me want to go back to Samsung....UGH!) Anyways, I currently have an LE2120 (Chinese Model) running OOS 1.2.5.5BA (European version) and I am well aware that out of the box the NA version does not come with Dual SIM hardware.
The question that I am not 100% sure of is would the software build still allow dual SIM? My gut strongly tells me no..
The reason why I ask is that currently I don't have access to 5G. I thought it was because my work SIM didn't have 5G enabled on the carrier, I was incorrect. I still don't have access to a 5G, just shows 2G/3G/4G. I thought maybe it is because I am using a EU build here in Canada where maybe the bands don't line up...I have done searches on why 5G isn't available but nothing seems to fix it.
Just a shot in the dark...for people much smarter than I am!
No, simply running EU rom on NA hardware does not enable dsds. You can setprop for dsds but it doesn't work properly, seems to wire the first sim card into both slots and cause a conflict
Maybe I didn't word my question in the correct fashion.
I have dual SIM hardware, in my case it is the Chinese Version but I'm told the hardware doesn't differ as it still a Global Version.
The question is NA ROM, on Dual SIM hardware. If the rom itself supports it. I would just try it, but then I have to wait for the next update.
If you have LE2120, then the EU build should get you dual sim
I have LE2120 and I'm switch to Oxygen OS and trying build AA/BA/DA all working with sim dual
About 5g .. i have same your problem no option 5g only 2g/3g/4g
First check your country bands support
First try:
*#*#4636#*#* and choose NR/LTE/CDMA/EvDo/GSM/WCDMA if not fix 5g
Another way to fix:
I'm fixed 5g same steps its was on op8p
Sorry about english

So you have tried your LE2120 on AA? Dual SIM is all working ok?
I feel like switching to AA would get me unto the proper bands here in my country, but leary to do it because then I have to wait to the next build. Unless I decide to go root/magisk.
I did try the *#*# method, but that doesn't do anything. I have tried several different dialers and it never brings up this menu everyone talks about.
