Still no VoWifi for some realme devices?
Upgraded from iphone SE to Realme GT Master Edition a few months ago, had to switch over to TMobile to get it to work since it's a GSM only device (TMobile has better plan prices than Verizon anyway) but it's still not an "officially supported device", as the TMobile IMEI check said it wasn't compatible with the network but has clearly been proven wrong. Haven't had a single issue with it until now, I'm on a trip visiting family and I'm sitting in the living room with 3 or 4 bars of 5g, but as soon as I make a phone call it drops down to 1 bar of E (basically the worst connection possible) and either doesn't ring at all or when the call connects its constantly cutting in and out. When I hang up the call it instantly jumps back up to 5g. Tried looking for VoWifi settings since I know this model supports that functionality, but it's missing from the usual spot so I guess it's a carrier specific thing based on information I've found while googling. Does TMobile not support VoWifi on any devices that aren't in their system whitelist?

I went to the local TMobile store and the calling worked fine there and after we left I tried it on the other side of town and it worked fine so I think we're all wrong, they said it was most likely due to a dead spot, we're right next to an overpass with the tower being on the other side and down the street so I guess that would do it. They recommended getting a booster by calling 611 so we'll try that. Still a little weird considering I'm getting full bars of 5g here with full access to everything with it, but it's just the calling that's being wonky. The booster should be overnighted so I guess we'll get our answer in a day or two. Could it be that it's falling back to non LTE 4g networks rather than 3g and it's just spotty due to a dead spot? I wouldn't mind that, especially with a booster set up
It needs to support VoLTE, which it more than likely does not. US carriers shut down their 3G networks over a year ago. Most Asian devices do not have compatible VoLTE implementations for US carriers, leaving them without the ability to make and receive calls.

Those things with an unlocked bootloader, rooting, and even using Qualcomm's tools to select the carrier pefile all illustrate that VoLTE, VoWiFi, and VoNR were never implemented by RealMe for the US market. This is actually fairly common with Chinese phones. There is a lot more to how a cellphone works and interacts with a carrier's network than just the band(s) it uses for connectivity.
So it's on Realme, not TMobile? Interesting
Yes. T-Mobile USA does not block device manufacturers or device features on devices not sold by them. I used to use a Xiaomi MI Mix 3 on T-Mobile. It worked fine with WiFi Calling, VoLTE, and was a great phone for it's time. You really have to know what you are buying though. Flossy Carter on YouTube tests a lot of non-North American devices on T-Mobile USA and Verizon.

Unfortunately I have been with t-mobile for 2 years next month!!! I've had the galaxy flip 3 from the day it came out.First few months no issues with the phone or service i was really enjoying my flip.Had to Move to a new place phone worked good for 3 months then my calls wernt coming in & when I tryed to make calls I would have to try multiple times to get a call out, And when I did get a hold of someone i would have to worry about the call droping but there were Alot of times it just wouldn't work! I Would have all bars 5g but no service.At the time I was dealing with really bad health issues And my doctors couldn't get intouch with me some times they were able to leave a message if they made it to the voice mail. It was so frustrating being sick barley able to take care of myself and my cell phone was my only line of communication. I had no family or friends that I could use there phone for messages or to talk. T-mobile went back and forth for 3 weeks with we are working to find out what the issue is we will call u in a few days if they could get through to me. So I was patient in the beginning. They said that it was nothing on there part that was stopping the service no towers down in the area blah blah . They recommend them sending a gadget that would maybe help bring a stronger signal but they didn't have any available at the time they would get one out to me asap when they did have some. I really wanted them to let me out the contract so I could go to a provider that would work for as much money as I was paying and maybe could get 1 call out of every 4 and if I could hold a conversation when I got a call . I was so sick that I delt i didnt have the energy to keep dealing with tmobile they were just giving me the run around with out any solution. I was able to get a pre pay phone to keep in contact with doctors and 911 if i was having life threatening problems. I had surgery set up and that's really all I needed to get well, and then when I was feeling beter to deal with tmobile I would. Basically I was told that because there tower's wernt Down in my area that it was really not there problem they couldn't give me any kind of discount for the bad service periods. They never sent me the boster I've had the same issues where it will work great and then it stops for months at a time. It really sucks because I'm at home 80 percent of the time with a unreliable service I'm disabled I'm not able to work anymore I used all my savings to live and they really couldn't help me with a different phone to see if that would work they wanted more money and I didn't have it. I've been stuck in this contract and the phone service has worked maybe a year and few months out of the 2years that is up next month and I'm done with Tmobile.IF I wasn't going through horrible health issues where to be honest I could barley take care of myself I just couldn't keep trying to come to some sort of resolution when really all you tmobile did was string me along with we will call u in a few days this went on for over a month and a half to be told Basically deal with it and I feel really taking advantage of at a time where I didn't know if I was going to live or die day to day and thank God I didn't need to rely on tmobile service to call 911 because would it have worked? SO THANKS FOR THE GREAT SERVICE AND GREAT COSTUMER SERVICE AND THE MANY PEOPLE THAT I GOT PASSED AROUND TO AND STILL HAD TO DEAL WITH SHITY SERVICE!!@%^

Not the case here, as I said there has been no issues prior and it connects to the TMobile 5g network just fine. Any phone calls I've made in the past have worked flawlessly so I feel fairly confident it supports VoLTE lol. It's just that it's started doing this now, I dunno if it's because I'm now on the other side of the country and TMobile here is different than TMobile back home or what, and the workaround would be VoWifi but like I said I can't find that and my research showed it's up to the carrier to offer that on the specific device
It is possible the band it was connecting to in your previous location is not deployed where you are now. There are the rare 2G/3G sites still in operation as well but how long they will continue to work for is unknown.
I found this article and it's a VoLte phone but realme never registered it for support in the USA.
The author of the article sounds like he had issues like yours.

I would agree if it was just 2g/3g consistently, but it only kills my service when I place a phone call. Any other time and it's usually 5g, maybe 4g in some areas. And it works fine for stuff like Whatsapp or Snapchat/Discord calling. Someone else said that Realme probably didn't register for Vo support in the US, whether that be VoWifi or VoLTE. I'll take a peek at the post they mentioned

This seems like the most plausible explanation, but while I'm out and about at home (work or going to the store etc) I can make and receive calls without issue through TMobile's 5g and 4g networks depending how the coverage is at wherever I'm at. So it works as expected usually, but it's just while I'm visiting family now that it's doing it
It's about location and the availability of a 3G tower in the area.
