When I add dun through the app it doesn't reflect in my apn settings, even after I reboot. I systemized it into system/apps.

if i was you try offline sim apn database make it a system app ive done it and then you can add dun apn but change to nxtgenphone apn use edxposed get download xtether and moto x hide that used to work i was red flagged on cricket with my s5 back in the day

best way if that doesn't work and you aren't rooted is pdanet+ i have old k20 running 8.1 only way to bypass tether on that was add the project Fi - T apn but TMobile is different from aio

with aio dont they use same as att if so the apn used to be BROADBAND i think its been changed to hotspot all caps

So I figured out that my hotspot works perfectly fine on Slot A but not on Slot b. It immediately turns off when I try to turn it on. Do you know what could cause it to work on one slot and not the other?

@EoMpton59 you are our fearless leader!!! Thank you! I have been reading 10 pages of this for the last 40 minutes or so.

Kindly, could you make an updated how to?

Perhaps in thread or in the orignal post? It would be super helpful. I'm having a hard time following all the updates and changes discussed.

I have a T-Mobile McLaren 5G and will fix it so it has root. That's my starting point.

Thank you again!!!

Any chance this can be adapted to the 7t (android 10) with systemless root? No stable twrp for this model yet.

I can see the apn-conf.xml but can't save any changes.

I use root explorer, but the issue is the /system partition is set up read only - systemless root. No R/W for /system :(

Looks like I need to read up on making a magisk module to symlink that file.

    Android 10 they moved apn xml to /system/product/etc make copy of xml make the changes user_visible="true" and user_editable="true" and its fixed in Android 10 Android 9 first you make 2 copys of your apn in system etc one for you to edit, one for when you mess something up it happens. in the xml you find your carrier and the dun apn add the line user_visable="true" it works this way you need to be able to see apn but not be able to write to it be careful after you edit copy it to back to system/etc change permission 0644 and reboot. the xml is UPDATED for Android 10 place in /system/product/etc/apns-conf.xml I did in twrp i put Android 10 in mega so it could be downloaded NEWos 10.0.2 NEW product/ect download link
    New https://mega.nz/#!ShFlTQwT!iNY2aIlcdr9wvQuHhmahH17dAprTZzoFtvmv9WZCKC0 for system/ect https://mega.nz/#!T8EHTYqY!TPNslQzQ-ZvZx5rqXIUXryHM89fwUCNjoF5c39AJmZM the ect controls mtu i have them matching for 310260

    never it just allows dun very easy I decompiled the framework.apk changed mtu dont prefer apn also but no they allow unlimited on TMobile but they only see it as data it unblocks apn after change you reboot and it's there just keep read only you only delete line user_visable"false" I used my manager to do so and changed permission to 0644 and root ownership and copied over in twrp I tested with file manager it just unlocks it if you change user_editable to true on main apn you can open speed

    it resets when you change xml or wipe dalvk other little things i do the one to keep 4g/3g only cbrs is CBRS (Citizens Broadband Radio System) uses TD-LTE to provide a wireless voice and data service at 3.5GHz (3550MHz to 3700MHz). The radio interface is exactly the same as for LTE at other frequencies, supporting voice, text and data services with seamless mobility. This frequency allocation spans existing LTE Band 42 (3400MHz to 3600MHz) and LTE Band 43 (3600 to 3800 MHz) i also enabled rdnis and pan (Bluetooth tether) to apn

    ive found ways to do this since galaxy s5 lol it will work on any phone db edits and if you activate it dont make it editable make it like mms and authority type put -1 i also changed mtu 1440 to 1500 and it works on 7t 7pro 6t
