I have recently got a software update on my Samsung S20 Ultra and have not been able to connect to the mobile network since. Both wifi and bluetooth work fine. I have tried a number of things including resetting the mobile setting, factory resetting the device and even re-flashing the device with the latest firmware but the mobile connection still doesn't work. When I access the service mode menu using '*#0011#' on the phone, I see the MIPI test fails on the SIM. Does any know how to fix the device so I can get a mobile network connection again ? Is the MIPI test failing related to the problem or is that just a red-herring ?
Exynos or Snapdragon Variant?

My device was originally with Malaysia firmware, installed the latest Indian Firmware so Jio Volte could be used.
I am getting volte symbol on the status bar however there is no volte related settings in the settings menu.
Also I notice the Internet is very slow most the time, if I enable flight mode and disable then the Internet will get a boost for a minute then back to slow connection.
Checked the sim in other phones, no issues. Anyone else has this problem? Any solutions....
Trying to Configure Note10+ 5G (N976V) with Visible but can not add APNs. The option is Greyed out. I was able to do it with my Verizon S10 that is also not officially supported. Crazy thing is that for about 5 min i was able to use the Visible SIM in my Note and Call and Send Txt until I rebooted the Phone. The Phone is paid off and Im using it on Mint Mobile now but it doesnt Show the T-Mo Boot Logo when I switched SIMs like my S10 Did. Has anyone been able to get this to work. I was told by Samsung that I may need to Reflash the Phone.
i have the regular unlocked note10+ working on visible.
N976V on Visible.
I am having the same issue, the APN settings are disabled. If you get this resolved before I can figure out a work around please let me know. Thank you.

Did you work it out? if yes, can you share how?
As soon as someone has resolved this issue, please update this forum page!
I just upgraded my note 8(on Visible) to the note 10 plus 5g. After i put in the Visible sim card into my note 10 phone, the phone was not working with the Visible sim card. I was connected onto the wifi network at work and I went into the settings to update the APN information, but it was greyed out and could not enter that information into the phone. After a few hours of googling to see if I could fixed the greyed out APN area so that I could actually enter in the programming, I said let me check the phone outside with wifi turned off. I went outside and tried to place a call and the call connected. I was then able to get wifi calling turned on since the phone was not allowing me to do so before. I went back into work and tried to place a call on the wifi network and it worked. I also tried sending text messages and mms messages and they all work. I checked the settings under the APN area and the phone automatically populated the Visible Internet setting but it was also greyed out, but it was working and I was so happy. I am so happy now with my new galaxy note 10 5g phone that is up and fully working with the Visible sim card. So I believe that having the phone connect onto the cell tower signal and not the wifi allowed the phone to pull in the APN information that it needed. I also reset via the setting the network connections while I was outside a few times. Hopes that this helps...
Change CSC with SamFw Tool (don't brick your device!!!)
Don't update beyond U4
Unlock bootloader and root.
Modify everything.
Accuse Samsung of being stupid for ever creating such a product with such limitations.
I have been given the Galaxy Young GT-S5360. I have a new sim card. Phone works fine for calls and I am able to access internet when using wifi, however cannot access internet when using mobile data. I have tried the SIM in another phone and have contacted the provider (plusnet). They talked me through lots of settings but without success. I have tried a factory reset. I'm not technical (at all) but seems odd that I can get internet with wifi but not with mobile data. I have also spoken to Samsung and they made me do another factory reset and agreed that odd that I can get with wifi. Can anyone help please?

I have s20 ultra purchased originally from Telus. Its unlocked.
Now I'm with Rogers but phone do not connect on 5G. It stays on LTE even though I have 5g coverage. If I insert my same sim in oneplus 8 pro I get 5g on that.
Talked to samsung and rogers and they have no idea. Both says everything good from their side.
Any suggestions?
Settings/mobile networks/Network mode.
Is that set to 5G/LTE/HSPA/GSM (Autoconnect)?
Also, try resetting network settings, as well as going into the APN settings and resetting to default.
I don't think you have to change your CSC to Rogers, but you may have to.
Already tried these steps with Samsung support but no result
Can you guide me how to change CSC to Roger's? Will it void warranty if I flash it ?
Finally the issue is fixed. Neither samsung nor rogers provided the solution but Google did.
Solution is to change CSC and immediately 5g and other features like volte and rcs chat started working.

Excellent!
I have a Galaxy S22 Exynos and I have troubles with mobile network. Although the phone shows it has full 4G or even 4G+ connection, Internet doesn't work at all, and only up arrow lights up. Turning airplane mode on and back off again seems to temporarily fix it. I've tried countless methods in order to fix it, but nothing seems to work. How to fix it?
I has same issue.
Moscow, megafon...
I have the same problem, its hardware issue and samsung doesnt want to admit it. I sended mine to warranty repair and hopefully they will fix it.
I had contacted samsung support for help and they asked to reset network setting, then all phones settings and then full format but none of those fixed the issue. Then they started to ask for log files but it wasnt possible to take the log file they asked for because it needs OTP password which i cant get because its only for samsung repair center. After that they said i should bring phone to repair.
Any news about this problem?
I'm tried switch mobile network to 3g/2g only mode and this is help, but not 4g or 4g+.
It looks like the phone can't switch from 4g+ to 3g mode and stuck.

I looked which band is faulty using the *#0011# code, and restricted bands with the Samsung Band Selection app from the Play store

This is not right though, it basically limits or possible connections... This is terrible...
