Samsung have a services mode (not include nexus)
type *#2263# in the dialer
it will go to Band Selection
we can control the phone receive specific band
it may be useful when your carrier is using dual band
and select the phone receive the best band at some very bad signal area
but except samsung, any other have band selection
or can we develop one?
in original android
have a Testing mode (all android phone can enter this mode)
*#*#4636#*#*
Phone information->press menu button , then select radio band->show Set GSM/UMTS band
it have six option, and i tested them in my GS2
they select the band as below
Automatic = All band
EURO Band = WCDMA 2100 only
USA Band = WCDMA 1900 & 850 only
JAPAN Band = WCDMA 2100 only
AUS Band = WCDMA 2100 & 850 only
AUS2 Band = WCDMA 850 only
I want to set 900 only in my nexus, but i got no way to set it
in the source of this original android testing mode
can we edit it to lock the phone receive 850/900/1700/1900/2100 only

BAND and Network selection in SGH i897
Hello Guys,
I am getting this (*#*#4636#*#*) option in my Samsung SGH i897 and able to select all the BANDS and Network Modes. After selecting several times WCDMA only with EURO BAND, its still picking EDGE (2G) Network. Dont really know what wrong i am doing or i dont know some perfect selection combination of BAND and Network.
Any suggestion please..
Thanks
Hi,
I have an unlocked SM-R750A which I'm using outside of the US. My carrier is using 900/2100 3G bands as opposed to the 850/1900 supported by ATT.
Is there a way to change and have it supported the other bands?
Thanks!
I have same problem !!!
is there any way to make it ??
No. Sorry guys. The hardware as it was tested by the Federal Communications Commission seems to show that there were several different versions with different radios.
I hate that Samsung did it but they definitely made separate US GSM editions, and a separate international edition, and separate CDMA editions, even though the Qualcomm S400 supports world bands including GSM/CDMA multi band support. Samsung was being sneaky and didn't do that.
is there any news on changing 3G bands?
Try this

Put watch into airplane mode and power down.
With watch off, pull the sim card then restart watch
Open the phone app and enter *#2263#
Select the band you want and swipe down on the screen
Power down the watch
Replace the sim card and power on the watch
Turn off airplane mode.
Depending on your watch version this might work for you.
Hello i have the same but different problem..I received mine(R750A) on 850/1900 instead of 900..Maybe we can swap if you dont mind.
Phone : LG K7 (K330) T-Mobile
Chipset : Qualcomm MSM8909 Snapdragon 210 (LTE model)
I tried to follow these guides : http://forum.xda-developers.com/z3-compact/general/guide-unlock-z3c-international-bands-t3091344 & http://forum.xda-developers.com/cro...ad-progress-please-leave-im-updating-t2871269 in order to unlock all 3G & 4G bands because the phone was bought in US and now I'm in Europe.
The initial state was that phone could only operate at 2G networks in Europe.
I tried several combinations on the enabled bands, like all of them enabled, only the European ones, only a few etc etc but nothing worked. The phone could not detect the SIM at all, or at some occasions it was in a loop trying to connect and was showing the "welcome to <carrier>" pop-up without actually managing to connect to the network/cell at all. Even when all bands were enabled, the phone could not operate even at 2G network (that was initially working).
(I have checked after reboots etc that the new NV values are saved as should).
At all these failing states, the process qmuxd was running continuously at 100% cpu (if this info is at any help)
Now, I reverted it back to US bands, and it operates at 2G
My question is: since the chipset (as mentioned at its specs) can operate at these bands, shouldn't it work? Is there something else I should have in mind, that maybe prevents the phone/antenna from operating at European bands?
Thanx in advance
You have to contact the carrier. T-Mobile 1st to see what options are available to you (since it's a US Phone), and then call your current carrier provider if T-Mobile can not resolve this issue. Hope this helps you.
i have lg k7 ms330
i need help for unlock band umts 900 (b8) of my k7 ms330?
Not sure, if the post belongs here or elsewhere, but here's the story:
Recently I've got a generic chinese fake specs tab. Jlinksz ZH960. MTK6582 1/16. Bad thing is that UMTS bands in engineering mode are disabled (shown but greyed), and only GSM are available. So the quest is what's the way to enable UMTS bands?
Same, i bought a Chinese phone, OUKITEL but doesn't enable those greyed bands. Hope there's a solution.
Hi, Is there any way to lock LTE band to Band 40. Currently i am using jio network( offeres LTE in Band 3,5, 40). How ever when i tried with " Network Signal Guru" app i cannot see Band 40 in the list,. Can anybody please advise?
Dial *#*#4636#*#* and change it from *select radio band".
Secondly, never post your QnA here... We have a different section for it bro.
Sorry bro for posting QnA in this section,. And in the select band mode i acn't see Band listes,. all i can see is ' Automatic, United states, P800, and one more ,.
You cant lock a especific band, only region bands on this hiden menu.
EDIT: you can follow this guide and lock the especific band, in your case B40
https://forum.xda-developers.com/le-max-2/how-to/guide-unlock-bands-leeco-le-max-2-fix-t3439154
But you can lost all bands or radio communication if do something wrong, bcuz you are locking in hardware the band not in software.
Check with net velocity app to see that whether your phone really supports band 40.
