[Q] How to Force N6 Into Using Band 12 - Nexus 6 Q&A, Help & Troubleshooting

Hello,
I'm with T-Mobile, and lucky enough to live in an area that has the new 700Mhz LTE Band 12.
My N6 is constantly using band 4. I would like to force it to switch over to band 12.
Is there a way?
Many thanks in advance.

Hi, please have a look at this thread:
http://forum.xda-developers.com/showthread.php?t=3020672

Thank you for the reference link. Perusing through the whole thread, it just about people checking in popping up across the country.
But, no indication on how to force switch band.

Awesome. Thank you.

My pleasure. Good luck!

T Mobile LTE Next Week

http://www.gottabemobile.com/2013/0...mobile-lte-next-week-followed-by-kansas-city/
Anyone know what sort of plans will change? I am in Vegas and I can't wait!
I feel they will unlock LTE to show of the network but who knows
I want to use the LTE already!
I believe a T-Mobile executive hinted that their LTE deployment would occur in the same order as their 1900 mhz refarming would. I wonder where NYC is on that list.
Glad they only care about the big cities Only get edge service where I live and work
Can Nexus 4 owners not do an network scan and find out if T-Mobile is testing LTE there? Just switch your phone to LTE in *#*#4636#*#* and do a network scan to see if anything shows up.
I dont see network scan when I do that code.

+1 to that. My friends out here on AT&T get 3 & 4G.
Could you please use one of the existing T-Mobile threads to discuss this?

[SPRINT] Enable Tri-Band LTE on your N5!

[deleted]
Great work. Should be useful to Sprint users.
You can skip the computer part if you install logcat and begin at step 5 after launching.

Wouldn't battery use increase from enabling this? Because it would be constantly scanning for the other 2 frequencies?

sweet!! thanks been wanting to get my MSL since i got the phone.. just hate talking to sprint reps to get it.. worked great thanks!!:good:
i live in fort worth and set 41 to 1 and the others to zero and i have lte , so does mean i have tri band in my area? and will the other bands set to zero still be used when needed . thanks

True enough, but you need to get the right logcat app, some don't work as well as others. I initially tried aLogCat, but didn't seem to work. CatLog app worked great, however.

Just saying. No one has been able to get a B41 (TDD-LTE 2496-2690) connection with a Nexus 5 and that's with actual maps of Clearwire sites that's been upgraded and knowing where each site is located at. I've personally visited over 24 sites to no avail and know of others that visited many sites as well. Looks to be a much bigger issue than just changing up the LTE Engineering settings and may be network related.
Just got the phone but I'm pretty disappointed with the LTE speeds 1/2mb down, outside it's a bit better. Went downstairs and it disconnects from LTE altogether. Anyone know if it's a radio (hardware) issue with the phone or firmware radio? Some spots of my house won't even catch LTE, whereas my s2 would get wimax.
I've tried spark but it makes my connection more unreliable more pocket loss, but indeed it does seem to make it faster, placebo? I'm in Los Angeles don't know if it's been rolled out. I tried updating prl/profile to no avail. My next choice would be to try the LG 2 in hope of it having a better radio.
GPS is spot on, and wow this thing is fast!
Just a question, but wouldn't prioritizing band 26 make more sense since that is the 800MHz frequency band?

No, band 41 has the most capacity so you would want to connect to that if you are actually in range of it. It will automatically drop you down to the lower frequency bands as you move out of range of the higher frequency bands.

Sweet, thanks for the explanation!
Hello, I tried this on my N% for Sprint today. btw. I live in N. OC, near Los Angeles. If I happen to be in and out of spotty LTE coverage areas. Will these adjustments cause more battery use or or worse performance?
When viewing HD youtube videos, it seems to play smoothly for a while, and then pauses as it the speed is going and up and down or being throttled.
About Band 41
So you means the Band 41 is unopen under default setting?
we need to open it by manual?
You know, the biggest mobile carrier China Mobile's 4G is TDD-LTE, and also use the band 41
But if I use the 4G sim card, it still work in 2G.

I am with uh60james spark seems to offer more throughput and less disconnects.
I drove to Corona from Carson the other day and i was shocked how much coverage sprint has improved on. I wasn't able to stay connected to LTE on my the entirety of my drive but it is impressive how Sprint has extended lte coverage around corona at least on the freeway.
Spark works better for me, less drop offs.
I am in Naperville. Will check this out and see if tri band goes this far out west from chicago.

I haven't heard anything about DFW having Spark anytime soon, so more than likely not. I live in Arlington myself, and would love to see this area Spark-enabled sooner than later.
Enabled this on my n5 a couple weeks ago .... dismal speeds on lte in downtown Los Angeles as usual around 4 down and 2 up.... Yesterday for the first time spark kicked in and I got 44down and 14 up. BUUUUT today its back and slower than ever. around 2 down/1up on LTE

Seems that due to Nexus 5 lacks TD-SCDMA for China Mobile 3G, it is very hard for Nexus 5 auto connect to LTE.
You need *#*#4636#*#*, change mode to "LTE Only" and wait connect to band 41/38 cell and then change it back to "LTE/GSM Auto (PRL)".
After it, you will on LTE until one of following happens: no LTE cell signal; incoming call; make a outgoing call. If fallback to GSM, you will need another round of "LTE Only" settings. Please check some chinese forums, there are plenty of guides.
It seems N5's baseband firmware did not implement some directly GSM to LTE function and do not support China Mobile 3G, so ...

T-Mobile LTE signal

I just got the phone on Monday. With the original ROM and after taking several OTA updates, my LTE signal strength at home and at work was horrible. I'd get around -120 dBm and it would frequently change to HSPA and even EVDO.
One thing that I noticed is that on LTE, it was using band 4, which is 2100 MHz. On my Note 2, it always used band 14, which is 700 MHz. The lower frequency penetrates buildings better and gave me a better signal at work and home (not great, but useable).
I just updated to the latest T-Mobile ROM from the developer site. The LTE signal strength is a bit better at -116 dBm and so far, it isn't changing to HSPA or worse. However, it is still using band 4.
Does anyone know why my old phone used band 14 and this new phone uses band 4? I would think that the phone would use whichever band gave it the best signal, which would certainly be band 14. Is there any way to force this?
Thanks.
I didn't look up the Note 2's specs but I'd guess it didn't have band 4. What are you using to see your band? OpenSignal?

I just looked up the specs on Wikipedia. It says that the T-Mobile version uses band 17, but I know that the phone said band 14 before I swapped SIMs.
Wikipedia says the Nexus 6 uses bands 2 / 3 / 4 / 5 / 7 / 12 / 13 / 17 / 25 / 26 / 29 / 41.
This is from the T-Mobile Support site: "TMO uses bands 2 and 4 on LTE/4G & 3G". Also from Support: "LTE band 4(1700/2100), 17(700)". I'm not sure what to believe, or what is in use around here. Like I said above, I know that the Note 2 said it was using band 14.
On the Nexus 6, I'm using an app called LTE Discovery.
T mobile only uses band 2,4,12 for LTE. The note 2 doesn't support band 12. I never heard of band 14.

I'm by no means an expert when it comes to bands/frequencies, however, if the app told you the Note 2 was on band 14, I think it was lying to you. I'm pretty sure there isn't even a band 14 in the U.S., and almost positive T-Mobile does not run LTE on that band.
When (if) band 12 reaches your neighborhood receiption indoors should improve drastically. On band 4 I usually get -109 to -101 dBm. On band 12 I get around -89 to -94 dBm.
I have tried different ROMs and different radio modems. Nothing I do gets me a decent signal. Very occasionally I have had a moderately strong LTE signal, but even then, the download speed is only usable and the upload speed sucks.
The phone doesn't stay on LTE for long. It switched to HSPA and even EVDO most of the time. On HSPA, my old Note 2 got at least 2 Mb downloads. This N6 can't even get a kilobyte down on HSPA.
I don't know if it really affects things, but I read some comments that a bad SIM could possibly cause this. Is this true? If so, I'll drop by the T-Mobile store again and ask them to try another SIM.
I love the phone for the big screen and other features, but I really can't live with this lousy data connection. If I can't get this resolved, I'll have to return the N6 and buy another phone.
I might consider a Note 5 if I have to. It only has a 5.7 inch screen, but my Note 2 had a 5.5 incher. I don't really use the pen and the price premium is high, but I don't know what other phones have a 5.7-6 inch display, except for some Chinese phones. I don't know if they are any good, or if I could use them on T-Mobile.
Call me frustrated.
have you verified apn settings? mine needed a few changes. band 12 should be rolling out soon. i saw it for a day here in portland and service was amazing. can't wait!

not sure. saw a few people on reddit mentioning they had seen it in my area. i have been using an app called lte discovery to check what band i am on. 12 only popped up once and haven't seen it since.

Yes, I am on T-Mobile. I meant Edge, not EVDO. Too many acronyms.
I just got home and even though the phone is currently showing three bars on LTE, the signal level is only -118 dBm, which isn't good. Speed test won't even do 1/2 Mb/s on download. This is pathetic.
As much as I otherwise like this phone, I can't live with this lousy signal issue. Unless someone knows of a fix, I will have to return the phone to Amazon. As I said, I have tried different ROMS and modems. I have also tried changing various settings that others have suggested (clearing cache, APN settings, etc.). I don't know what else to do.

Because of the choppy voice calls, as well as the lousy data connection, I am returning this phone and getting a Note 5. Although it is my personal phone, I also need a reliable phone for when I am on call at work.
I have spent all week on this and can't waste any more time. I need something that works. My Note 2 was reliable. I hope the Note 5 will be also.
Thanks to all for suggestions.
I too am having LTE data connection issues on LYZ28K. Anyone on LMY48M having data issues? I tried setting phone info to "LTE only", but that didn't help. I don't need wifi calling, so I'm wondering if I should switch to LMY48M?

Android M LTE bands check?

Hi Guys,
I had hard times finding how to get the MRA58X T-Mobile version of Android M, and by the time I got it, I'm not sure I'm getting Band 12.
I tried checking it using *#*#33284## but it doesn't seems to work. Do you have any idea how can I check it?
Thanks

There is an app for that.
and youll only get it if tmobile has it in your area. i always get band 4, as im right outside band 12 coverage.

unlike what less informed posters may say there IS an app for that... https://play.google.com/store/apps/details?id=com.blueline.signalchecklite I'm able to check what band I'm on with this app by looking next to the "sprint" carrier name it will say what band it's on (B41/B25) except while on band 26 since it's the default band they had before doing the multiple band thing, tmo should work the same, alternatively in the same app the frequency of the LTE will appear next to the "LTE" network descriptor no matter what band it's on (mine says LTE 2500 since it's on band 41 which uses 2500MHZ)

I always use the SignalCheck app. There is a free version and a paid version.
Thank you guys for your responses.
I actually live in the Bay Area at Stanford so I guess I should have B12 according to the coverage map.
I don't see it though, on both apps I just see the B4. Could it be that the Band4 signal is stronger and that's why I don't see the band 12 as well?
I remember that when I received the phone it had like a T-Mobile app and I had it until I upgraded to Android M on my own, now when I downgraded and upgraded to MRA58X I couldn't see that app again. Could there be anything connection between the two or should it be enough if I just have that firmware installed?
you'll get the bands if they're in the area, apps don't mess with connection on that level... b4 is faster and has more room for tons of subscribers (1700 mhz), so if your phone can see it it still prefer it to b12 which is slower and narrower (700mhz) however it does penetrate buildings better and go further in the country so it's more reliable. they also have b2 (1900mhz) is faster than b4 and b12 but goes less far from the tower and can barely go through a wall... if your phone can see b2 it will prefer it to bands 4 and 12

Forcing LTE Band 3 on Honor 9 Lite

Good morning,
first of all I want to thank you all for including me here in this community. I guess I'll be surfing this site many times, so I decided to register and give my contribution for the future if I ever came across scenarios regarding Android devices in general which may be useful for the community.
I'm here to ask a question: I've got a Honor 9 Lite mobile and my mobile network provider is Iliad, based in Italy.
The mobile network works like a charm in 2G and 3G mode, but when it comes to run in 4G, it won't work at all. I already unlocked the only 4G mode using the "Setting Database Editor", but that doesn't work at all.
Apparently, the only LTE band I can use is Band 3 (1800 MHz), but I can't find a way to force my mobile to use that specific band frequency when it's set to 4G mode. Does anyone have an idea of how to sort this issue out?
Many thanks in advance for any helps!
Eddie
