US Cellular SM-G920R4 Galaxy S6 APN Data Connection Locked to 3G - General Questions and Answers

I have a US Cellular G920R4, unlocked.
USC has co-opted the data connection. For example, I can add an APN for Verizon and select it, but it doesn't work.
If you set the APN setting to default and remove all APNs, it dispalys a message that states that "APN settings are disabled for the current user profile."
Data is 3G by default.
Also, they've locked the browser such that you can not remove or even change the default home page, which is the USC portal.
How to I eliminate their default setup and restore the APN settings?

I was having a problem with this also and I was able to add a working APN by disabling WiFi first. You'll still see the APN settings disabled error until you add the new APN. You'll then be able to select the radio button next to the APN you added after it has been saved. It worked for me just now so I hope that helps you.

Thank you for taking the time to reply. I am glad the solution worked for you and, hipefully it will help others. The WiFi settings on my device were disabled. I can add an APN and select it as default, but it's ignored - even after I delete all APNs by returning to default settings and starting over.

[Q] Avatar 4.2.2 Rom LTE APN issues

I have an S-OFF ATT HOX. SuperCID. Installed the Avatar 4.2.2 rom. Works great! Snappy, and pretty! Only problem is I was only able to get 4G speeds. After a 30 min conversation with ATT to confirm there were no issues on their end, I looked at the APN settings for PTA. The APN settings were incomplete.
Normally the APN type has default,mms,supl and hipri but my installs (3x) never included. I attempted to add the hipri to the APN and even create a new APN, but the changes would never save.
Any thoughts?
Is the APN locked from being edited? Try just making a new APN with the correct settings.
Avata 4.2.2 APN woes
Its not locked. I can get into the existing 6 APNs and create a new one, but there is no save button on a new APN or existing APN. But I guess by definition means it is locked. I speculated just pressing back auto saved the entered settings but alas, no LTE goodness
Weird. I've seen where the APN is locked from editing (Save button is grayed out) such as the default APN on the AT&T stock ROM. But even then, you can create a new APN and save it. Never seen where it locked you out from editing and saving altogether.

Hangouts APN settings? Do I need to fill it in?

Hangouts as I'm sure you know, has it's own APN settings. Is it safe for me just to delete all of the profiles?
If I delete the APN's in hangouts, It uses the system set APN correct?
Also, my carrier gave me this info, and I want to make sure it's all I need(In device settings)
Name
APN
MMSC
APN type
Is that all I need? Just asking because I noticed there were a bunch of other settings, and my connection always cuts out (probably a carrier/location issue).
Still waiting on hangouts update, thank God they added Google voice.
Bump!
You do not have to fill in the APN settings inside Hangouts unless you are having problems with the application. The settings supplied by your carrier should be all you need to configure in your mobility network APN settings.

APN settings not appearing!

I have a carrier unlocked AT&T One A9 with the bootloader unlocked and use a T-Mobile SIM card. Calling and SMS work just fine, but I can't use my mobile data or MMS. I figured out that this is because my APN settings were not properly configured, so I decided to punch in the T-Mobile APN settings. (Just to point out, the screen where all the APN settings should show up just says "APN settings not available for this user") There's a little floating notification that says "APN settings saved" but the screen remains unchanged, without my APN settings. I thought of S-OFF -ing it and flashing another ROM would help, but I can't come up with the $25 for a Sunshine license.

Not sure if you still need the info, but the reason the APN settings don't seem to save even though it says "Saved" is bc of some bug.
The way to to get it save is to click on the BACK button instead of clicking to save. So after you input your APN settings, DO NOT click the SAVE APN settings. Just click on your in-screen back button. Your APN settings should then be saved.
I updated my a9 sprint by using RUU side load, but my sim card is locked and i can't receive neither a call nor use data could you help me unlock my simcard pleasee

Change APN in Android Terminal with Root permissions

Hello,
I have succesfully made a script to Add APN Configuration to my Phone inside Terminal with Root permission. Actually I can change the default APN settings, but it take only action after Reboot.
Is it possible to enforce Reload APN Configuration without reboot?
I use my Phone as Internet Access Gateway connected to my Router a Raspberry Pi. I would like to change my outgoing IP-Address from my Mobile ISP if needed. The trick here is to add the very same APN Profile a second time and switch between them. With this trick I get another IP-Address in 2-3 Seocnds and without reboot.
I am able to change the Default APN but I was unable to Switch to another APN Profile without reboot.
I would very pleased if someone have an clever idea to change the APN Profile without Reboot.
Thank you very much!
NOT possible: settings are read-in at boot.
Thanks for your answer!
I made a macro that change the APN with the Userinterface it opens Settings -> Mobile Networks -> APN Accespoints and change the APN to the other and save the actual APN to a file. This action pattern changes the APN for me at the moment. it works, but I thaught about another possibility to not use Macros.

Question SOLVED: Edit Greyed out APN on Pixel 7 Pro? (No Root)

UPDATE: FOUND SOLUTION IN 3RD POST BELOW!
So im rooted on my Pixel 7 Pro.
Im experiencing daily occurances where my phone goes into NO SERVICE.
Toggling data on or off doesnt work.
Only restarting the phone works.
Which brings me to this..
I have Visible wireless which is Verizon based.
Problem is I cant edit APN what-so-ever.
Its greyed out. So fine tuning my APN is off the table.
However I do have root and I do have access to my build.prop file (even though FX explorer wont let me mount to write which is another problem).
Does anyone know how to work around this APN block or point me in another forums fix?
Im on Factory Unlocked Pixel 7 Pro Android 13.

Try this app, and enable apn editing. If it lets you after that you'll be able to. But it doesn't work on Verizon, you can add an apn but only edit the name of it.

Thank you TotallyAnxious but I got a working solution that doesnt involve adding modules to Magisk and appears to not require root. I do have Magisk and LSPosed running but this is working on my Visible (Verizon) service.
Ok so Im on a factory unlocked Google Pixel 7 Pro Android 13 (rooted but that doesnt matter and neither does being factory unlocked) with Visible Wireless (Verizon MVNO) and my APN is greyed out. Apparently Visibles carrier update I have for 2023 didnt patch adding apn, they just hid it.
I just downloaded "MIUI Hidden Settings Activity" app in play store by "NetVor - Android Solutions" and opened the "Access Point" shortcut which opens up the hidden by verizon option to add APN and save it! I have my 2nd APN selected right now in settings.
I basically copied everything my carrier APN has except I didnt select "NR" under bearer type which is the 5G connection. It wont let you add "dun" for APN type for tethering/hotspot so I added it in all CAPS as "DUN" and it worked! Tested hotspot and it works great.
Now my phone wont lose service trying to connect to this stupid 5G causing NO SERVICE on my sim.
For many this is how you add APN for troubleshooting.
Important to know: Using this other app called "Network Type Switcher" by "Cracky" in Play Store allows Testing menu which is *#*#4636#*#* on your dialer to "select prefered network type" to remove "NR" (5G) as folks previously have been doing to stick to LTE 4G, however, if your APN bearer allows 5G (NR) then it will try scanning for NR band and when it finds it and cant connect (because of your prefered network type on LTE 4G) it will cause a mismatch and youll lose service showing "NO SERVICE". The only way to fix it is rebooting.
Make sure your Select Prefered Network Type reflects whats in your APN bearer.
In fact as long as you just remove NR (5G) from apn bearer then it wont even scan for it even if your "select prefered network type" allows NR (5G). So no need to change it. Just remove it from your APN bearer and itll stay on 4G LTE.
Removing NR (5G) from apn bearer was my ultimate goal and adding a new apn but If your goal is to just add tethering/hotspot with "DUN" (such as "APN type: default,spul,DUN") then thats all you need to do.
No need to change "select network prefered type".
If you mess up adding a APN and want it deleted just go to settings, network, sims, apn, select the 3 dot menu, reset to default and itll go back to what your carrier set.
I dont think you need root to add APN with this app above. It never prompted for root access and didnt require it. No need to modify build.prop since they just hid the add apn setting.

It's an app, not a module. It actually can work without root as described in the readme.
