1700 and 2100 wcdma on N7100 intational

So I was playing around with my unlocked note nd I found a selection of bands nd I can select them but not sure yet if it does unable 1700 nd 2100 bands to work on wind mobile or tmobile any ideas ive the pictures

What code did you enter to find those options?

Note 1 had the same menu options.
It doesn't mean anything without actual support in the phone.
I assume, like the Note 1, if you turn those on your phone is going to reject your sim card.

Hi just peeked into this and was able to select 1700 band, go to comi bands and select 1700 wcdma and any other missing band and it will be selected. If it makes any difference i dont know since im in a good refarm area for tmobile.

By the sound of it our hardware just don't have the bands but yet we can select them kinda strange but if you could try using tmobile sim let use know what happens

I was able to do this also, with the leaked XXDLJ2 FW (4.1.2) - I tried with earlier FW before and couldn';t get into the menu - could be total noob error though...
Remove SIM card first.
Then power up Phone, dial #*197328640*
Select: DEBUG/PHONE CONTROL/NETWORK CONTROL/SELECT WCDMA BANDS
from there, it seems you can select ALL, or add the bands you want. (I'm on TMO USA so I selected 1700/1900/2100)
Now, what I don't know is...once you re-insert the SIM ( and you have to power cycle to do that) does the TMO SIM override the changes I just made? I have very weak 4G near my house so I cannot check if 4G is working or not.
CORRECTION: Forget what I said about removing SIM card !!! I was able to access the menu with the SIM inserted, and it looks like my settings are holding ( there's an asterisk next to the WCDMA bands I chose). This is promising!

I did this on a stock rom and after rebooting settings stay the same. Cant tell if itll make any difference since im at work and dont get good coverage. Will report as soon as i can and im on tmobile california

Sadly, it appears that any other setting than Automatic will disable WCDMA altogether - I sat in my car for 20 minutes right under a cell tower tryin to make it work, but was stuck on Edge...as soon as I selected AUTO, my phone jumped to H+ ...and it was on the 1900 Band since the 1700 band is automatically unchecked when switching to Auto. Oh well...gotta wait for the damn TMo refarm then.

The TMUS reframe is killin' me. Neither my house or work are in a reframed area. However, there are several points on my commute that are reframed, and I did have a chance to eat dinner in one. Holy moly is HSPA+ fast! EDGE is virtually useless with these devices.

you can select mulit bands that way you dont have to use auto as it does turn em off ,i used the last selection it lets you select what you want

Sorry to check in late but with these changes I notice that my signal sticks to 2g and barely wants to switch to H or H+. Maybe when Im off work Im gonna try to select all wcdma band and switch to wcdma only in network mode. when selecting network mode i notice it changes all the settings in the service menu.

that's what I've been doing - COMBI BANDS, and add GSM 850/900/1800/1900 and WCDMA 1700/1900/2100.
But it didn't work for me, phone remains stuck on EDGE -

I dont think this does much only put me in Edge mode or no data at all. Its weird that theres an option for it. So ya no luck here...

No LTE Option On Mobile Network Setting

Hello all, i got Note 4 LTE N910G, but in my mobile noetwork option i only got WCDMA Only, GSM Only and WCDMA/GSM. Need help here. I try *#2263# (service mode) to apply all band but it didnt work.

Are you sure you have bought Samsung Note4?

Does your mobile operator has LTE? Usually you don't see LTE option when your network doesn't support LTE.

Try this way (ROOT is required):
- Install ES File Explorer, open the menu and enable Root Explorer option.
- Locate the file /data/property/persist.radio.lteon
- Open that file, and change its content from false to true
- Reboot the phone.

Hey Jusho,
I'm having the exact same issue with your issue, no LTE option with TELKOMSEL. Have you fixed your issue? If so, how?
Did you purchase 910G in Singapore?
I went to Singapore recently and was able to go to Samsung Service Center... we tried a couple of things :
- Use M1 USIM card in MY Note 4==> LTE option appears
- Put my TELKOMSEL USIM in THEIR Note 4 ==> LTE option disappear from THEIR phone
- Put OPTUS (Australia) USIM in MY NOTE 4 ==> LTE option appears
Today, I went to Grapari and asked them to replace the USIM and tried with the local Samsung Store :
- Put TELKOMSEL USIM in their Samsung EDGE ==> LTE appears
Any idea?

Hey guys, I had that same problem on my galaxy S4 before. I used a Straightalk sim card running on Tmobile. I called straighttalk and they replaced the sim card and everything worked.
Call your providers and ask them to change your sim for LTE compatibility. That is if your providers support it, and your phone supports the LTE bands.
Good luck

I did mention that I have replaced with the new USIM (4G card) and LTE option won't appear. And yes, my provider supports LTE Band B8/900 Mhz

XT1527/XT1528 bands

Compiled from FCC information and Wikipedia for two of the Moto E LTE models:
FCC ID IHDT56QC8 (XT1528) -
This LTE transceiver supports high-speed wireless data communications within LTE Bands 2, 4, 5, and 13, with channels up to 20 MHz in bandwidth.
FCC ID IHDT56QC7 (XT1527) -
This LTE transceiver supports high-speed wireless data communications within LTE Bands 2, 4, 5, 12, 17, 25, 26, and 41, with channels up to 20 MHz in bandwidth.
From Wikipedia:
2 = 1900Mhz (PCS)
4 = 1700Mhz (AWS)
5 = 850 (Cellular?)
12 = 700 a
13 = 700 c
17 = 700 b
25 = 1900 g
26 = 850 (SMR?)
41 = 2500 (old WiMax)
So, the Verizon model (1528) will technically support LTE on AT&T and T-Mobile bands 2 & 4. It has all three Verizon LTE bands (obviously) - 2, 4, 13. You would be missing LTE on AT&T band 17 and LTE on T-Mobile band 12.
The other model (1527) will support LTE on AT&T in 2, 4, and 17. Will support Sprint on 2, 25, 26, and 41. Will support T-Mobile on 2, 4, and 12. Technically it might also support Verizon on 2 and 4. (Verizon is currently using 4 as part of XLTE in certain markets, and I don't know if think are running LTE on 2 at all. )
It appears that the 1527 model is the better one to get for band coverage, unless you want Verizon LTE on band 13.

Found a third model. From FCC docs:
FCC ID: IHDT56QC1.
This mobile device is also equipped with an LTE transceiver. This LTE transceiver supports high-speed wireless data communications within LTE Bands 2, 4, 5, 7, 12, and 17, with channels up to 20 MHz in bandwidth.
This particular variant will work on LTE on AT&T in bands 2, 4, and 17. It will work on LTE on T-Mobile in 2, 4, and 12. It will work on Verizon's LTE on 2 and 4, but is missing Verizon's core band 13 (700c). Not sure which provider is using it with on band 5 (850). This model apparently (compared to QC7) is missing the Sprint LTE bands completely (25, 26, 41).

Does the Verizon XT1528 support GSM bands?
All postpaid Verizon 4g lte have UNLOCKED GSM bind if I am correct. Has Verizon been able to block GSM bands in the Moto E 2015?
I have been trying to figure this for last couple of days.
Thanks

I got the VZW Moto E working on a AT&T GoPhone SIM. The phone complains that it isn’t a VZW sim and there isn’t an option to switch to GSM is the settings menu. Though you can definitely adjust that setting elsewhere (no rooting involved). Just install this app "4G LTE Switch" . All the app does is spawn an activity that is actually in the Android Settings app that normally is only accessible by a special code in the dialer. Motorola has removed that special code, so you have to get at it this way. This app is hardly the only one to do the same thing. You could do the same thing from APEX launcher by selecting the right activity to spawn in the Android Settings app.
Once you’re into the Phone Info menu, just scroll down to “Set preferred network type” and choose LTE/GSM. Once I did that, the phone connected to AT&T LTE. I was able to place a call as well. I also saw it drop to H+, so I know UMTS was working as well. If you reboot the phone though, it will revert to “LTE/CDMA” mode and you will again have to change it back to “LTE/GSM”.
A STRONG WORD OF CAUTION... There is a menu in the upper right hand corner of the phone info screen. In that menu is an option to "Set Radio Band". In there, you will be presented with two options. Choosing either option will limit the bands your phone will use at a given time. It will not open up more bands for you to use. By default, your phone's baseband (the processor that controls the radio) will select bands automatically without restrictions. Once you make a selection from this menu, YOU CAN NEVER GO BACK TO AUTOMATIC MODE. (Never say never... you can just reflash the baseband to reset it... but you don't want to have to do this) A factory reset doesn't fix this because this setting is made in the phone's baseband and not within Android OS. Bottom line, don't get curious and use the "Set Radio Band" option. I made this mistake with a Moto X and was finally able to fix it by reflashing the baseband.

This intrigues me as well. Airtel, the most popular carrier in India, runs GSM 1800,900 UMTS 2100 LTE 40 (2300). The VZW Moto E according to the RF Exposure Report on the FCC for IHDT56QC8 says that the Moto E only supports CDMA 1900,850 GSM 1900,850 UMTS 1900,1700,850 LTE 2 (1900), 4 (1700), 5 (850), 13 (750). That would mean that there is no way that a VZW Moto E would run on Airtel. Does the phone support more bands than are listed in the FCC filing or did you do something else like flash a different baseband?

Thanks for the advice, It worked with app "4G LTE Switch", BUT the sim card is still not recognizable, I mean it says Sim card is not from Verizon. Luckily the phone and the SIM card are working now. Thanks again my friend

Appreciate the warning, but there is a simple workaround I just accidentally did this and the radio was disabled, but if you set 'LTE/GSM' in the app, and then go into normal 'settings -> Wireless & Networks -> More -> Cellular networks -> Network Operators -> Choose Automatically' will bring back auto selection.

How To: Selecting/Deselecting network bands

First want to put it out there that you do this at your own risk
I love that T-mobile has Band 12 LTE coverage but for me the data speeds on Band 12 are horrifically slow, so I prefer my phone to be on Band 4 LTE (at least while at work).
I used to do this change all the time on my S6/Edge and the steps are vary similar to do them on the S7(slightly more involved).
To start with, if you mess with bands, it can(and probably will) affect some sort of your service
So to change network bands you have to enter the service menu. To do this, go to the phone dialer and enter
*#2263#
Once here you will see a screen saying ServiceMode followed by various options
To turn off Band 12 choose LTE Band Preference (#4 on the list).
Then hit next page until you see Band 12 and deselect it (this will remove the * from next to it).
Once that is done, in the top right you'll see where it says "More" select this and choose "Back" - do this until you get back to the main page
Now back at the "Main Menu" choose "Apply Band Configuration" (option 7) and you're done.
Once you exit the menu(by hitting either home or the back phone key) you'll lose signal for a second while the phone switches the bands around.
To revert back to normal, enter service menue *#2263#, choose "Select All Bands"(Option6) and then Choose "Apply Band Configuration" and you're back to normal
Hope this helps someone
EDITed the info above so that you can turn off just Band 12 and keep calling features

Updated the instructions, figured out how to make the phone stick to Band 4 and still retain ability to make/receive calls

Oh Ya band 12 is terribly slow. At least when compared to band 4. Band 4 is wideband at 20x20 20mhz bandwidth while band 12 is 5mhz bandwidth. It's just barely enough.

I was wondering why my speeds suck since I've upgraded to a new phone guessing this is why

Do you have any approximations of the speed difference between the bands, like with speedtest or something?

I didn't notice any difference in speed with my tests was really hoping for better. I'm only getting about 15-20mbps now I was getting between 60-80 about 3 months ago

T-mobile V20 Band 12 solved

I know some people were having problems keeping or even getting on band 12 with the V20. The people at T-Mobile were useless, even the engineers. After much poking around, I found a solution that works...for me at least and hopefully for you guys.
I had a hard time finding a dialer code that got me to the right menu. This is it. Now, this is, as far ask I know, only for the Tmo version.
*#546368#*918#
Tap Field Test
1. Modem Settings
2. LTE-A CA setting
3. Choose Pcell B4 Scell B17 option
4. Choose Restart Later and hit the back button
5. LTE Band selection
6. Choose Band 12
7. Reboot
(if you still aren't getting band 12, just dial code *#546368#*918# then just do 5 and 6 again.)
I get a solid band 12 connection all the time. This has helped tremendously with battery as well. It's connecting to a much closer tower and not connecting to a band 4 tower a zillion feet away.
Hope that helps!

I am on T-mobile. How do I find out what band I am using? Thanks!

Dialer code doesn't seem to work...

(if you still aren't getting band 12, just dial code *#546368#*918# then just do 5 and 6 again.)
I get a solid band 12 connection all the time. This has helped tremendously with battery as well. It's connecting to a much closer tower and not connecting to a band 4 tower a zillion feet away.
Hope that helps!

There's a free app on the play store called Network Cell Info Light.
Just run that and hit the Raw tab and you can see the band.

+1 and also how to go back , my speed seems worse now.
edit : well it shows me on band 4 .. hmm
edit 2 : set to airplane mode then back and now its on 12 ...
If it goes back to band 4 , that just means its a better connection?

What's the model number of your phone? Mine is showing LG-H918.
Is that what yours is showing?

yup. it's a t-mo v20.

I've followed your steps through 4 restarts now and I can't get mine to stick. It switches to Band 12 (verified with LTE Discovery app) after step 6, but once I reboot or go to airplane mode and back, it goes back to Band 4. Any ideas?

Yes that's a common trait of band 12. You get much better coverage but speeds aren't as good. For me, it's still good for what I need plus no dropped calls, awesome connection and no battery drain. Was a worthy trade-off.
Enter the dialer code, modem settings, LTE-A CA, hit the top most option (it'll say all enabled). Back button, LTE Band, band you were on before. Probably band 4.
Or you can just reset network settings and it'll detect everything by itself.

No need to reboot after just doing steps 6 and 7. Should stick.

Weird, are you copy and pasting with an accidental space at the end? Make sure the last character is not a blank space but the end actual of the code.

typing it manually.

Tried it both ways. I was hoping the reboots would help, but no dice. I've been repeatedly selecting Band 12 through the Field Test menu. I'll select 12, then go to the LTE Discovery app, see that it's on Band 4. I'll toggle airplane mode to see if that triggers something, but still no dice. So then back to the Field Test > Select Band 12, rinse and repeat. No matter what I do I can't get it to stick.
What's your network mode setting? Settings > Wireless Networks > More > Mobile Networks > Network mode? I'm using GSM/WCDMA/LTE Auto.

Yea I'm on auto too. I never restart my phone or use airplane mode so that might be a hitch. Actually, it's kind of a good thing cuz band 4 is always there if you need it.
I'm gonna add the dialer code in my contacts so in case a reboot is called for, can just toggle it back to 12 real quick.

Just for ****s and giggles, try copying it from my original post and pasting into the dialer. If that doesn't work, that is weird. I'm not sure why it would work for others and not you. Strange.

It's all dependant on what you need. Like I live in Woodstock GA. It's kind of the sticks and I was lucky to get one bar and phone was always hot.
But now getting 5 bars easy.
Just weigh what is most important to you and decide from there. Plus you can always just change the band back to band 4 if you want.

Worked flawlessly. Thanks.

Code not working for me either. I'm definitely Tmobile. I've tried manual and copy/paste. It just disappears.. Thinking it might be something I've frozen.. I'll look.
Nope. Unfroze only thing it could have been in my list and still..

I'm using the 996 unlocked version and I can't seem to set the band ( responds with FAIL). Sad

T-Mobile h918 here and does not work.
I manually enter code in dialer and hit call and all disappears and no menu. Very odd.
