Still no VoWifi for some realme devices?

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!!@%^
