Mobile Data not working on Revvl 6 Pro 5G // stuck in EDGE service type

[MajorFoulestDragons1]

Hello, I recently put Pixel Experience/Pixel OS on my T-Mobile (wingtech) REVVL 6 Pro 5G. The version is: TQ3C.230805.001.B2 PixelOS_treble_arm64_bN-13.0-20230821-1122. the install did not take long after figuring out how MTK Client worked, and how to use it to unlock my bootloader and such using Fastboot and EDL mode. After installing the GSI, setup was fine, but I noticed I no longer have the ability to use my 5G service or even 4G. I get stuck with EDGE as the network type. I have 0 mobile data access at this time. I am still able to make calls and send texts, but that's basically it that I can do without being on WiFi. I guess my reason for reporting this issue is because I would like to know if it is a current bug, or if it may be my phone. Any insight on what is causing it and what I can do as a workaround to get my mobile data working again would be greatly appreciated.

Ok, so I was able to locate a workaround for this issue. The issue when you are stuck with EDGE, and it loops between no bars to 4G and then to EDGE, Can be fixed by opening settings>about device, and click on Radio Info, above the SIM Status option. Now, some phones may not have this option, so the otber method is entering ##4636## in your phone dialwr. When another screen appears, select "phone information", and it will take you to the same screen as doing the Radio Info method. Once you are on this screen, you will need to turn off the mobile radio power to temporarily disable your internal modem. Why do you want to do this? Because of the frequent updates from frequently connecting and disconnecting to the towers, it will dramatically slow down your phone, so turning this off will save resources while you change your preferred network type. What I found works to restore cellular data in this instance is setting the preferred network type to NR/LTE. Once you select that, turn back on your mobile radio power. Once you turn it on, you will see a lot of things showing up in the field above. What you want to specifically check is: data service, voice service, data network type, and voice network type. Once completed and the data service shows Connected, you have now restored your Mobile Data on your phone. But, there is another thing to tackle. In my case, I resolved my network issue, but lost the ability to make calls or send texts. So what I found works, is you go back to the Radio Info/Phone information page. Youll hit the 3 stacked dots, and select IMS Service Status. If it says not registered in the field that says IMS Registration, then you will need to install the APK provided and restart your phone. Once completed, proceed with testing your Mobile Data by navigating to Google.com in your browser, test your calling by dialing a friend to make sure your phone works, and then a text messaging test to ensure your phone is sending texts properly. Completing the steps provided above should return your device to a state where it is functional. There may be times you may have to repeat the process for the Mobile Data, as there are times it changes itself to a different network type. It may take 3-5 minutes after setting the network type back to NR/LTE for the data to fully connect.

Originally this issue ticket was supposed to be me inquiring on the issue, but I managed to find the answers to my own question, and I am sharing these answers with anyone who reads this in the event they are countering the same issue I have had.

An image for each screen you need to go to, along with the APK for the IMS services, will be provided in the next comment.
