I just bought S20 Ultra. My service is thru Total Wireless but it is a Verizon phone. I bought a new SIM and went thru all the hoops to activate it but I have no data, and no messaging. It shows 4G LTE on the top but it is greyed out. When I try to make a call it shows 1X. Also when I go to APN settings I can not add or edit and it displays "APN settings are not available for this user" I spent 11 hours between CHAT and Phone calls with Customer service. They had me factory reset twice, reset network settings, power on with and without data/wifi/roaming and or airplane mode on numerous times . They said they were updating my APN settings every time and pushing something thru to my phone but none of it worked. I tried to put a non working sim from T Mobile in and then add an apn but every time I would change the MCC it would disappear when I went to save. I don't know what else to try but I am hoping one of you might be able to help !!

Have you tried a factory reset? If that doesn't work perhaps flash the latest firmware with odin

Nice one...
Try this.
Install Nova Launcher. Long press an empty area on your home screen. Add Widget, choose Activities. Then go to Settings and select APNs. This will create a shortcut with APNs, open it and normally you will see the + sign to add an APN.
I made this script to edit apns, use adb. You will need root most likely, selinux permissive on some phones. Another route(without root) is "Settings database editor" app. Use adb to allow it extra write permissions as it instructs. Without ui it's necessary to edit databases manualy. Edit the script, it will remove ipv6 from an apn as it is, change "protocol" to what you want changed in apn, for example add "dun" to "APN type" by changing protocol:s:"IP" to type:s:"default,supl,mms,dun" the script will display current apn values for reference.
adb push fxapn.txt /data/local/tmp
adb shell
sh /data/local/tmp/fxapn.txt
Or just factory reset your phone/reset network settings.
Last time I had a phone do that it was locked by the company ( T mobile ) for non payment but the IMEI came up clean. Try someone else's Sim card that you know that works.

When I boot into factory recovery mode, beneath the selectable options it lists,
"# MANUAL MODE #
--Appling Multi-CSC...
Applied the CSC-code : unknown
Successfully applied multi-CSC."
(Typed exactly as written, spelling mistakes and all)
Shouldn't my CSC be VZW?
When I do *#1234# the CSC is from my stock image.
How do I get it back to what it should be?
I unrooted, went back to stock recovery.
When I boot up, I get a pop-up saying, "Unfortunately, Factory Test has stopped."
I set up a lock screen, but when I turn the screen on it never asks me for the code.
Any ideas how to undo this and get back to stock, so I can restart from a known good point?

Have you tried wiping all data/cache/dalvik and re-Odin'ing the factory stock image?
Yep, tried all that multiple times. After a Factory Data Reset, this pops up on the first reboot (it's fading out, but at the bottom of the picture, you can see it say,
"Factory Mode is on. In this mode, some functions aren't working properly. Wi-Fi is turning off now. Please change to user mode before verification."
Does anyone know how to "change it to user mode"?
Thanks!

Found the solution in this post by xliderider:
http://forum.xda-developers.com/showpost.php?p=28815755&postcount=349
Open a terminal emulator
Type su
Then enter the following after the #
echo -n ON > /efs/FactoryApp/factorymode
(yes ON is the correct setting to turn it off)
Then I had to reboot for the change to take effect. FYI, I had to go through initial setup after the reboot.
Finally! I'm back in the game!:cyclops:

Which notification - the pop-up or the mostly faded out notification below it?
The faded one only shows up on the first boot after a factory reset when you're in the Factory Test mode. It fades quickly and took me 8 tries/resets to get that screenshot!
The popup happens twice every reboot when in Factory Test mode...
Once I used those commands in terminal emulator, rebooted, it took care of the problem.

My Wi-Fi had been working fine since I bought my phone almost a year ago. I recently downloaded "Words with Friends," and that app has crashed many times on my phone. After a crash on that app today, my phone restarted itself --> and I noticed that I was unable to turn my Wi-Fi on. I click the Wi-Fi button in the quick settings menu, and it is green for a while and it turns white again. It does not even find any networks since it cannot turn itself on.
I thought that maybe if I upgraded my firmware that this would fix itself. I have now upgraded to the latest firmware via Kies. However, after the upgrade I tried to connect my phone with Kies again, and it doesn't want to connect. It says: "No sim card inserted. Unable to continue communication." My sim card is inserted, and I am able to make phone calls like always.
Note: I have never installed any custom rom's on my phone. Everything is original. Also, I have deleted "Words with Friends."
Yes, I have tried to restart the phone several times, as well as removing/inserting the sim-card.
Can someone please help me with these issues I am experiencing?
• Unable to open Wi-Fi.
• Unable to activate Mobile Data.
• "No sim card inserted. Unable to continue communication." with Kies.
• Unable to get into Settings > Security ("Unfortunately, Settings has stopped.")
• Unable to adjust screen brightness from home screen (swipe the quick menu bar at the top).
It seems like I cannot take screen shots either (I used to hold in the home button and click the power button before), but it does not work any more.

How can I save my messages so I have them after the factory reset? I managed to save my contacts in a vCard file and put that on my computer.
I tried to factory reset, and everything seems to be working fine now.
I managed to save my contacts (exported them from the phone and imported them back in the phone), but sadly not my messages. My pictures did not get deleted from my phone, neither did my created folders and my content in there. My apps were deleted, however I only had free apps that were easy to install again.
Thank you guys for helping out.
What do you think could have been the cause of this?

Have you tried one of the APN settings apps on Google Play Store? Some of them come packed with APNs from all over the world, so the setup is simple.
https://play.google.com/store/search?q=apn&c=apps
(I can't recommend one, because I don't use them.)

Dont need apn setting, My ZU work and data work but if I reset to factory default, I need to re enter my apn manually. (APN don't appear automatically)

That's why I suggested trying one of these apps, so you don't need to enter the APNs manually.

Xperia Z Ultra APN Settings Help!!!
I just got an Xperia Z Ultra phone, and I have had MUCH difficulty trying to find the right APN settings. I've bounced from site to site, and nothing has worked. Straight Talk emailed me APN settings and they didn't work. I think it's because they sent me an older sim card and gave me new settings for their new sim cards. Last night at one point, I DID get it on the edge network, but because I didn't think that was good enough. I cleared those settings, and now I can't remember them to even get back to that point. I'd rather be on edge than nothing at all.
I previously rooted my friend's G3 on Sprint (LS990, ZV4, KitKat 4.4.2) with Stump Root, and used this thread
http://forum.xda-developers.com/lg-g3/general/guide-g3-hotspot-apn-edit-t2889436 to make the hotspot work. He updated to ZV6 thinking it would fix some LTE issue that was happening. The LTE problem was related to coverage and eventually went away on its own, but now he lost root. I found out how to wipe and downgrade back to ZV4, did that, rooted with stump root again successfully, and tried to redo the hotspot fix. I assumed it would work as simply as last time, but when my friend went to turn it on, he said the WiFi Hotspot option is missing.

I have tried everything from play store replacements to widgets to build.prop edits but nothing seems to work; the best I have gotten is creating a network with the chainfire tether app but being unable to get any internet through it. I'm assuming the missing option is an indicator that the hotspot is completely disabled somewhere else. Any ideas?
This same thing happened to me after downgrading you have to do the ##RTN# fix. Just revert to 100% ZV4 (unrooted) like before. Then call sprint and ask for his msl code. Once you got it go into the dialer and type in the ##RTN# click "reset" and type in the code from Sprint. This will wipe everything and reset it with everything that originally came with the phone. After the reset then root it and do what you wish.
You could try flashing the apns from here. http://forum.xda-developers.com/showthread.php?p=56953010
You might also try updating profile and PRL. If that doesn't work, try entering ##72786# in the dialer. I had a similar issue, and that fixed it for me.
Did you ever figure out how to fix this?
I figured it out! change ro.build.target_country=US to ro.build.target_country=COM
Instead of resetting you could also manually enable it if you have root and app 'Shortcut Master(Lite)'
In the app, do a search for 'ChameleonNodeMenu' and launch it.
Click 'Tethered Data' and SET value to 3.
Reboot
If you're on a MVNO, it is necessary to enable manually (if disable) as it will not auto enable with ##RTN#.
You can also enable Roam setting menu by setting Roam Pref/Menu Display value to 1
Missing hotspot capability after using LGFlashtool
I lost my hotspot tethering when I used LG Flash tool to fix a phone that was stuck in a continuous start-up cycle. I have an LG Volt with Android version 4.4.2, Kernal 3.4.0+ Build number KOT491.LS740ZV6 and Software version LS740V6. When I use root checker, it states Root access is not properly installed on this phone. I do not think I tried to root it.
I have tried apps to get my computer to use my phone as a hotspot since that ability is now missing on my phone, but I cannot get them to work. Can you please explain how to do this? I see ways listed above (tethered data or ro.build.target), but I do not know where to start to even get those to work.
Thank you!
I've got a S7+ 5G with the TMB CSC and I'm having a trouble with the APN settings. Using an activated T-Mobile sim in it shows an APN with most of the correct settings but the "Mobile virtual network operator type" is set to "GID" and has a value set below it. This setting is not enabled when using the SIM in either of my other phones. The tablet connects to 5G but has no connectivity I get a notification to "Sign into network" which opens a webpage that never loads anything.
Trying an At&t SIM in it shows no network connection(cancel symbol where signal bars are) and gives me a few APN options all which have the MNC set to 280, which I've learned from here is for T-Mobile. Trying to change that setting to the proper one "410" either deletes or hides the APN where it is not available.
I have a Visible Wireless(Verizon) SIM which works perfectly with no configuration.
Talking to Tmobile support they confirmed that the device was originally sold by Tmobile and is not network locked. After verifying the software is up to date we exhausted all troubleshooting options and contacted Samsung support who's only options were to have it repaired out of warranty for a fee or trade it in for less than what I paid for it.
The software on this device is very peculiar, there are no carrier apps or carrier splash screen on startup. The tablet came with an older software version (security patch dated sept 2021) and would not download an update on its own. I then factory reset the device, used samfirm to download the latest version and odin flashed all but the USERDATA option. There are still no carrier apps installed and if I didn't know any better I'd say it was a generic CSC.
I'd really like to use this device on At&t, 5G or not, and I suspect there are others who would like a carrier-less experience too. Can anyone tell me whats going on with this thing? I'm happy to provide more info if needed.
