Hi,
Does anybody tried to access ServiceMode on Note5?
I tried *#0011# and it goes to connection info but the old method (Back, Q and 0000 input) seems not working, at least on my N920CD device.
I want to have access to main ServiceMode to be able change some settings, so share your knowledge and experince about this subject, thanks.

Nope, the usual suspects don't work for me. *#197328640# does not work. Q0000 doesn't work, nor does *#2263# for band selection. SM-N9208. Maybe I won't go international next time.
No LTE-A
No WB-AMR (HD-Voice)
No VoLTE
Hi all i need urgent help my samsung galaxy note 5 SM-N920I can only be used to make a call when set to 2G mode only am on T-mobile network USA.
This is not New
I want to know if anybody can help to post the Band coverage by screenshoot on their Note 8
I am just wondering by Turning on/off band preference on their service mode, it will resolve the speed problem on Data and coverage problem, As we know some people buy the hand set such Unlocked version . US carrier (TMo/Ver/ATT/Sprint) version ,International version , but they don't use the same carrier the note 8 is manufactured for.
Like mine My Note 8 is T Mobile version .
You can see by press => setting=>about phone=> Service provider SW ver. last line is TMB/TMB/TMB
By Checking Service Mode for Band Coverage by dialing *#2263# on dial pad you will see like mine below
With TMB/TMB/TMB , I found after press 2 that WCDMA Band preference==> some band not supported .
please stated what model is your Note 8 firmware while you do iit and "Service provider SW ver"
this is also will help us to make decision if changing carrier/Carrier switching by flashing the FW is necessary.

Thank you
Good morning
The service mode doesnt work for my note, do you know if theres another code to access that menu (I have the international version and wanted to check my coverage/data)
Hello,
I use the Three network in the UK with an unlimited data plan and they provide a service called 4G Super-Voice also know as VoLTE.
To get this working I had to flash my Note 9 with the 3 firmware which is annoying because of the boot screens but its worth it for VoLTE.
Anyway, I can only access 4G Super-Voice if I put my phone in aeroplane mode and then off aeroplane mode. I then can see using *#0011# that I am using band 20 which is used for 4G Super-Voice.
With this, I can access VoLTE, better signal and faster 4G speeds. But after 30seconds it goes back to Band 3 and I no longer have access to VoLTE and the faster speeds Band 20 offers.
I have had a look online and a few people have fixed this on other devices by only letting the phone access Band 20 and disable the rest. On my Note 9 when I try entering Service mode using *#2683662# I'm left with a blank screen with no options to select. Not sure if 3 have locked this on there firmware or if I'm accessing the menu wrong. Any Help is much appreciated. Thank You

Yes, you can lock out certain bands while allowing others, but the *#2683662# code has been deprecated in the latest models/firmwares.
Enter this diag code *#2263# or *#2766338378#, tap LTE Bands Preferences, one by one deselect all the bands you don't want (especially band 3), tap on Go Home or Go Back/Previous, and finally tap on Apply Band Configuration. If you did everything correctly your phone should no longer pick up the unwanted bands.
Here's some more information about this issue.

Hi guys,
I have rooted my note 8 with deluxe ROM to access hidden network setting option to lock specific band of network. As we know that, Hidden network setting option is disabled by Samsung but, I rooted my device and download apk of hidden network setting and placed in system with help of root explorer. Everything went perfect. Now, I can access section where i can select specific band and lock it. I access it with Shortcut Master Lite. But, When i tick on specific band and toggle the selection button then it shows message success. Immediately my network change to my selected band. I can check from *#0011#. But, if my phone remain in stable state for few seconds then it automatically switch to another band. Which mean it didn't lock to specific Band. When i go back to hidden network setting, there is no tick on my selected BAND but toggle but still says that i am on selected band option instead of LTE ALL. I am using India Jio Sim card which support Band 3, 5 and 40. I get very good internet speed on 3 and 5. But, It automatically switch to Band 40 when its remain in stable state.
I want to lock it to Specific band only. Can you help regarding it. I am using deluxe ROM with Android 9.
Thanks

Hello, were you able to fix this problem ?
Am going through the same atm
I'm facing the same issue on my N950F. Don't understand why samsung locked this on the Note 8, most new phones allow this setting. Any way to work around this with root ??
Edit: this is what worked for me https://forum.xda-developers.com/t/how-to-lock-lte-band.3681480/#post-74325453
TL;DR: Get org.vndnguyen.phoneinfo (no longer available on the play store), and run ServiceMode as root. Follow the guide above to disable unwanted LTE bands. Finally a solution that works for devices which Samsung disabled the "Band Selection" menu method (blue background issue).
