[Realme GT Neo 2] makuaz:
Good afternoon! Greetings from Mexico! A few days ago I bought a Realme GT Neo 2, I currently live in Mexico and use a company called "Bait" from Altan Redes (which uses band 28), this information will help me to explain and comment on a question that I have AND I CANNOT SOLVE.

According to the Realme website, my phone is the "realme GT NeoFR(12+256)" version; what I suppose is from France and therefore a version of Europe, so far everything is fine, right?

Well, not because according to the manufacturer's specifications, this super cell phone supports VolTE and supports band 28; when inserting the sim that I have in a OnePlus 5 from the Mexican company Bait with the hope that the VolTE will be activated and I can receive calls or dial, something that for 10 days I tried in a thousand ways and I could never activate said service, call operated and they told me the following "Your equipment is not approved to work with our network" pfffffff!!, and it is curious that said activation option does not appear in the settings.

How do I "half" solve this problem, since it is a dual sim, buy and enter another "BAIT" sim with activated data and use my previous "BAIT" sim, degrading the signal to 2g so that calls can come in and out.

So far I would like to know if anyone has a solution to this problem or has had the same problem that I face.

After reading here on XDA I did the following:

Firstly, the equipment came with the firmware RMX3370_11_A.03; and when reading in detail in the forum I realized that if we use a VPN it is likely that it will release an update to be able to unlock the bootloader and be able to flash the phone and change the region (with this flashing I thought that it could activate the volte or some functions different to be able to use my phone with the "BAIT" operator).

For this first Update I used the psiphon Pro application and the country of France.

After trying a vpn and a lot of patience the phone first received the RMX3370_11_A.05 update.

After a few days I kept trying to upload the version of the phone and simply with the vpn for hours and connected to WIFI I did not receive anything, that is why I thought what if I change the country when using the VPN? and bingo I was able to update to the RMX3370_11_A.06 version for this case I used the same application but using the vpn of the country of Bulgaria.

With this update it was first possible for me to unlock the booloader following in detail the tutorial of the brother @RMX3370 (thanks for the tutorials)

Once the bootloader is unlocked install TWRP and Magisk to root the phone; again following in detail the tutorial of the brother @RMX3370

After this process and with the unlocked bootloader flashie and change regions through Europe, India Latam etc.... NOTHING OR ANY version of firmware activated the VolTE.

For flashing, follow in detail the following tutorial from brother @SrCDA:

https://xdaforums.com/t/softunbrick...ion-relockbootloader-realme-gt-neo-2.4399223/

All this process BooLoader unlocking, flashing, firmware installation (region changes) was done under MacOS BigSur without problems; That's why I tell you to follow all the guides in detail since I see that sometimes they ask many things recursively when the same authors of the guides solve them in the publications.

After trying and trying to get the VolTE to work I have resigned myself to staying in the INDIA region and I am already using the phone for daily use; only now there is another problem THE FINGERPRINT READER DOES NOT WORK, I have tried to put my fingerprints and it is really annoying to unlock it with a code; I have disabled magisk's biometric authentication BUT IT HAS NOT SOLVED ANYTHING.

I've changed the android calling app to avoid the "This call is being recorded" announcement, and uninstalled apps that slow down the phone to leave the stock rom as clean as possible.

It is a fast phone, well configured and I really like it; but I list my problems again:

- There is no VolTE for band 28 of Mexico

- Issue with fingerprint reader shaking when trying to add them to unlock the phone.

Note: if any user requires that I support him in something with all pleasure!; If anyone can ask for my listed problems or faced the same thing and managed to fix them, I would really appreciate some tips to finish configuring my phone!
