[Q] How To Manage Band Priorities?

How do I edit the band priorities?
Other phones' band priority settings can be edited with the ##DATA# > LTE menu, but this phone has only the LTE enabled/disabled option visible.
Is there a workaround, or is this a limitation of the phone?
Thanks!

Force band 12

One of the good things about the gs6 is the ability to for b12 and even better ability to choose preferred band in automatic mode.
Does the m9 have some sort of ability like that?
You are talking about the WIFI channel 12 (which is illegal to put your WIFI on in the US)?
Actually I think he is talking about forcing a specific LTE band... (in this case LTE Band 12 which I think is for T-Mobile). Specifically accessing the LTE Band service menu.
For any Samsung device you would enter *#2263# and the "LTE Band" service menu would open up and you can force a specific band. IF this is what he is talking about, it’s actually a great feature because you can "lock in" LTE to a specific band, I use to do this all the time in the Philippines so I wouldn't get kicked off the LTE band. You can also see what LTE bands the phone supports.
When I had the M9, I looked everywhere and tried to find the code to access the LTE menu but I was unsuccessful. Maybe someone here has the code to access the LTE service Band menu. There were some generic codes that work for Google in general BUT none of them worked on the M9.
Try *#*#4636#*#*

*#2263# doesn't work for me
But yes LTE band 12
##DATA# on Sprint lets you do something like this, but I believe that code is Sprint-specific.

Band locking

Is there any way to change network band to B5(850) without root.

Samsung s20 enable UMTS 4 question

hi all,
Have a question about unlocking the umts band 4(aws 1700) for a s20 sm-g9810 HK version. Hope someone can help me to sort it out.
Following the guides in this forum, I enabled the band using QPST and QXDM to write NV 1877. The white was successful, and the Samsung Band Selection app shows wcdma IV 1700(it wasn't
there before modifying NV). However, when I select the band or change network mode to 2G/3G, I can't make any call with Freedom Mobile, which is using UMTS 4 for voice.
Does anyone know if the hardware supports this band?
Thanks!
