Note 5 and Band 12 - T-Mobile Samsung Galaxy Note5

I notice on my Nexus 6P, it tends to connect to band 12 quite often. At home where I have 3 bars of band 4, -122 dBm, restarting the radio will force the 6P to connect to band 12. I can't replicate this on the Note 5. I actually haven't seen band 12 on my Note 5 before.
Do you have this issue in band 12 areas? The baseband is COKC.

I tend to also check my Note 5's Service Mode now and then. It appears the phone prefers Band 4 over 12, which makes sense because Band 4 has much higher bandwidth than Band 12. There have more been instances lately where I will have Carrier Aggregation showing Band 4 and 12 together. The only time the phone will primarily use Band 12 is if I'm deep in a building and Band 4's signal is too low.
If you use #*2263# in the dialer, you can tweak these settings. You can force Band 12 if you want to for testing.

Weak Cell Signal

On my Nexus 4 I used to get LTE in my office. Granted I had a hybrid radio installed on that.
With the Nexus 5 I can pull 3-4 bars of H and H+. Anyone else notice this. Funny how the "uncertified" phone for LTE gets a better signal.

It's happening to me too, brother. I too had Nexus 4 that was a champ at keeping an LTE signal while I was within LTE coverage, but this Nexus 5 treats LTE like it has cooties or something. I feel like I have to demonstrate to the Nexus 5 that I have LTE by going to the secret dialer menu and selecting LTE Only and then switch back to LTE/GSM. However, if LTE gets to 2 bars or less, the phone switches back to HSPA+ and stays there. Some suggest that this saves power, but I call BS on that. I really did not notice a difference in my Nexus 4's battery life when I enabled LTE--it seemed the same to me.
On my N4, a low LTE signal would be faster than HSPA at full strength. I want my N5 to try harder and I have been souring these forums to see if there is some sort of fix. I'm going to try and get a new SIM and see if that fixes anything.
I have the same problem. Great signal for HSPA but bad on LTE. Did you try a new sim card? Any fix out there?

Nexus 5 poor signal strength on Ting...

Hello,
I have been seeing horrible quality of network service in my area on Ting. I have a white 32GB Nexus 5. I work in a three story building that seems to turn my phone into Digital roaming/CDMA 1xRTT network only going outside I barely get 3G. I have mapped it out and see more service in the area where people on Sprint are getting 4G LTE in the area or WIMAX. I was wondering if anyone on Ting/Sprint has the same issue.
I do see 3G on my commute and downtown Sacramento, California where I should see 4G LTE I am barely getting 3G 2 to 3 bars. Most of my day at work in Folsom, California area is all 1xRTT 2G or Roaming when inside my office, and lower end 3G outside. I have two 3G/WIMAX towers next to my area at work in Folsom and I should be getting some 3G.
I went through the cell network code to enable band 26, and band 41 and changed priorities on the band from 1 to 0 and individually tested each band in my area. band 41 seems to be the best and the others are pretty bad. Band 41 gets me -100 dBm, 99asu, 950ms ping on CDMA 1xRTT.
I now have it back to all priority 1 (Bands: 25/26/41) Band 26 and 41 enabled. I have updated my Profile and PRL multiple times.
I am running 4.4.2 with Xposed Framework version 1.5, with Franco kernel r33. I did see Franco kernel r34 and will probably flash the update ASAP to see if it works any better. I am not using any power save settings for cell network quality. I am also using a Spiegen slim-armor case and tried to see if it was interfering with signal strength, it wasn't.
So my question comes down to has anybody known a fix for getting solid 3G in an area where I should be seeing some LTE and atleast full strength 3G. I am barely seeing 2G most of the time. I am just crossing my finger it isn't an antenna issue with the phone itself.
Any help, tips, or tricks would be greatly appreciated!!!

Go to about phone and check your Baseband version, if your modem driver is older you may want to upgrade it. Or if it is newer, potentially a downgrade has shown better performance as well. All depends.
Read this thread thoroughly and make sure you do a backup before doing anything and see if this helps.

Look for the modem thread (didn't see you post it so if you did, sorry), and try flashing the .15 radio. That seems to be the best. The stock 4.4.2 radio (.21 or .23 can't remember) sucks. I could be halfway between towers and drop to 3g and not get LTE at all. The .15 holds LTE as long as there is really an LTE signal just fine.
i just read that ting uses sprints network. that might be the issue there, as sprint isnt known to have great coverage nor great data speeds.

Sacramento is entirely legacy lucent equipment. Basically **** sucks and won't get better anytime soon till they cluster launch the area. They won't fire up anything (3g / 800 mhz / 4G LTE) until they cluster launch. They can't cluster launch the area until all 200 or so sites are fully upgraded which is a ways off.
B41 is running of old Clearwire sites for now and should be mostly done by around may but you cannot connect to them unless you force LTE only mode and do the PRL update work around (i.e. PRL update every time you reboot the radio) and even then it leaves much to be desired.
So your option is to stick it out on the ****ty legacy network or find another provider that suits your needs. ATT is running 5 mhz on LTE 700 B, Tmobile has a 10x10 FDD-LTE network on AWS that is spotty as **** in around south sac area and drops to Edge when you go indoors which is probably a no go for you.
Probably the best option for you is an ATT MVNO considering your needs are inside a building.
-- Though if you do stick it out Sprint has quite an amazing portfolio in the Sacramento area with full access to eSMR 800 (5x5 mhz FDD-LTE band 26) + eSMR 800 1xAdvance, 20 mhz of PCS A-F + the 10mhz of PCS G (5x5mhz FDD-LTE Band 25) along with 55mhz of BRS (2500) + innumerable EBS (2600). Right now they're running B41 on EARFCN 40978 which is about 2630mhz or smack dab in the EBS block.
Tmobiles is here at 40mhz of AWS and ~30 mhz of PCS + the 700A later this year. They run 10x10 for FDD-LTE Band 4 and DC-HSPA+ on the other 20 mhz of AWS. They run a single PCS 5 mhz WCDMA 3G carrier and the rest of the PCS is GSM. Their 700A Band 12 will be limited to about 3x3mhz FDD-LTE when they deploy later.
ATT has quite a mishmash of spectrum. 12 mhz of 700B Band 17 (5x5 mhz FDD-LTE), 700D block Band 29 which is unpaired and unusable, the Cell 850 A block, 10mhz of AWS good for 5x5 FDD-LTE on Band 4, and 20 mhz of PCS A + D which is split for numerous WCDMA 3G + GSM carriers. So they're probably going to run AWS LTE and aggregate it with their 700B block LTE and then moving onto refarming PCS carriers later. IE -a nightmare.
Take your poison.
I'm not in your area, but Ting has been swell for me in Minnesota. Sprint's coverage map shows NO LTE in the Twin Cities of Minneapolis & St. Paul, though it exists well to the west in rural MN. Imagine my surprise to get it at my home in Hopkins, at least 75 miles away from Sprint's nearest report of coverage. Phone service is unchanged from when I was a Sprint customer.

Yes som ting is wong
Firstly it looks like when you got your service you only provided them the ESN number which they can provide you 3G and 1X
however you need a sprint 4G lte sim to actually get LTE along with 3G and 1X ask ting about it.

Is there a way to force Band 26?

So I live on the edge of LTE. At home, I tether. I have to have my phone set in certain spots to get a usable signal. I've noticed that sometimes I'll connect to Band 26 with a significantly better signal. I've also noticed that Band 25 has gotten worse... 25 gets a signal of - 114 in a really good spot and bounces to - 115 which stops working. Band 26 gets - 105ish.
So, is there a way to force the phone to connect to Band 26?

How to force my one to connect to LTE band 40.

Hello all,
i have a problem, in my area ther are two LTE 4g bands coverage- lte 3 and lte 40.
My phone always remains connected to lte 3 band because it has slightly good network strength, but i want to connect to lte band 40 because it has very high data speed. in my office it connects to band 40 but at my home it remains connected to band 3, i get 100kbps (band 3)speed instead of 5-7mbps (band 40).
So how can i make to connect my phone to band 40 and not band 3.
I am rooted have supersu, busybox, multirom, nethunter on cm 13.1.2

even i want to lock my phone to band 40 but there no way possible because jio speeds are too low on band 3
Not possible as a phone will always connect to a strongest signal available within your area....in your case (at home) band 40 is not the strongest so it will connect to band 3 instead while in office its the other way around...

Possible to disable Band 4 on unrooted Verizon Pixel?

Recently I've started to experience exponential increase in dropped signal/phone rebooting/radio cycling on/off. It looks like my home is at the edge of verizon's band 4 coverage. They must have switched on or changed tower config over the past couple months, as that's when it started.
Essentially, my pixel is trying to connect to band 4, which is around -105 to -115 dBm. As a result, signal drops frequently. It'll connect to band 13 sometimes, which is great at -85 to -95 dBm. The thing is, seems like band 4 has priority, as the phone constantly drops the more stable band 13 connection in search of band 4.
Speedtest shows no benefit to me the enduser, as I am getting around 100/18 connection on both band 4 and 13. It's gotten to the point where this would happen every couple minutes, making the phone unusable.
Staying on wifi solves the data issue, but that's not ideal. And I still see the radio cycling on/off trying to search for signal even on wifi, which means I could potentially lose calls and texts.
Any suggestions on how to temp disable band 4, or at least prioritize band 13 over it? Thanks!
