Oneplus one on Koodo, no LTE

I've tried everything! Have the 16gb version, edited apns, deleted certain areas, re added. Checked info screen.
I got lte on my nexus 4 with the exact same settings from koodo. Not sure why the oneplus won't pick it up..

Probably have the Chinese version which lacks the LTE bands for koodo. LTE well only work with Rogers or Fido on the Chinese version.

Does the back of your phone have Cyanogen in the back? What is your baseband radio in Settings->Display?

Radio is m8974. It doesn't say cyanogen on back at all.

I'm not familiar with the Canadian bands, but you have to look at the Chinese OPO and compare that with the Koodo LTE bands.
It could be possible that your friend has the Chinese version and is able to get LTE on Bell but not on Koodo or he has international which works.
Do the research and see if its compatible to begin with.

Mobile services provided by Koodo use Telus Mobility's CDMA, HSPA+ and LTE networks. CDMA devices, however, have been discontinued by Koodo outside of Northern Ontario and Manitoba.[9] Koodo Mobile's CDMA and HSPA networks use the 800 MHz and 1900 MHz frequencies while their LTE network uses 1700/2100 MHz (AWS).

Here's a list of LTE bands that North American companies use.
https://en.wikipedia.org/wiki/List_of_LTE_networks#Americas
It looks like Bell uses LTE bands 4,7,and 17 while Koodo(which is owned by Telus) only has band 4. If the back of your phone doesn't have Cyanogen written at the bottom then you have the chinese model. I'm sure Telus may eventually roll out more LTE bands but for now you might be out of luck.

OnePlus One on LTE Band 5

Fellow XDA'ers:
I've tried asking this in the "Unlocking additional LTE bands" thread, but haven't had any success. From that thread, it seems possible to unlock LTE band 5 on the One, although it does say that not all bands can be used due to "hardware limitations". From what I've read, that seems to be limited to Band 20 though.
My question is: has anyone successfully got the One working on LTE Band 5 (850mhz)? It's the only LTE band available in Vermont at this time. I followed the instructions and changed all the NVRAM values, but I can't get LTE to work. I know 850mhz here is shared between GSM and LTE. Is there something else I need to do besides editing the values? Do I have to select any bands in software? When I dial *#*#4636#*#* I have LTE/GSM (PRL) selected, "Automatic" under band selection, and then I have LTE set in Cyanogenmod.
Any input is greatly appreciated!

I assume you double-checked after reboot that the values remained in place? Did you do the rmt_storage patch? Without the patch, the values wont stick in the latest modems.

Yes, I've double checked to make sure the values survive a reboot. I also used the patch. After some research it looks like there may be an issue when band 6 and band 19 are enabled that causes Band 5 to not work on LTE. The problem is that I don't know what NV value I should use to only enable LTE bands 2/4/5/17. Is there a way to calculate this value?

Yes, you can use NV Item calculator from here:
https://play.google.com/store/apps/details?id=org.vndnguyen.nvcalc&hl=en
The NV Items are standard across all Qualcomm based devices.

Thank you! I calculated the value for bands 2/4/5/7/17 (matching what is available on the HTC One (M8). I'll give it a test this afternoon.

Still no LTE love here in Vermont. I used the NV Calculator to determine the NV 6828 value for bands 2/4/5/7/17. That value came out to be 65,626, which I input as 65626. I wrote the file, rebooted the phone, and verified that the settings kept.
My iPhone is connected to LTE on Band 5. My OnePlus just won't connect.
Are there any other settings that may need to be changed?

Did you update 6829 as well? I believe one is the supported bands, while the other tells the it which of those supported bands to use.

Yes, I did change both the 6828 and 6829 values. LTE is selected under mobile networks in Cyanogenmod, and LTE/GSM (PRL) is selected under *#*#4636#*#*. The band selection is set to automatic.

Mistakes may be easier to spot with some screenshots:

Hmm, I don't see anything wrong.
I guess one last thing to do is able band 5 only and see if it works.

I tried that as well. For some reason the phone can connect to 850mhz on GSM, but not 850mhz on LTE. I can say for sure that the OPO does not support LTE on Band 5 even if the band is theoretically unlocked.

Have there been many people who can confirm that this unlocking method works at all for the Chinese OPO? I've been trying to get Bands 4 and 7 to work and I can't get anything above H+. Does this only work on a certain ROM/version by chance?

The method used on the global version of the OPO isn't specific to that version. All qualcomm-based devices are subject to the same method. You can find more information here for the OnePlus (both global and Chinese variants), and here for other qualcomm models such as the Galaxy S5. Both forums show that many people have had success unlocking additional bands.
Now comes the bad news. Just because you theoretically enable a band on the phone doesn't mean that it will work - as is the case with Band 5 on the global version of the OPO that i'm using. The phone also needs to have the correct antennas to connect to those bands. In my case, I can connect to GSM using the 850mhz band, but for some reason the same band cannot be used for Band 5 LTE (850mhz). I don't understand why this is the case, but I have yet to be able to get it to work.
Your luck may be better. It looks like the Chinese version runs bands 1/3/7. The global version is 1/3/4/7/17/38/40. If they do indeed have the exact same hardware inside, then a simple software unlock SHOULD allow you to turn the Chinese version into the global version. If they have a different antenna, then your results may vary.
As far as I know, there is no specific version or ROM that you have to have. If you have one of the newer versions of the software, you need to be rooted and install the RMT patch. See the first link I posted above for information on how to do that.

Been to that thread, it's kinda dead now. Followed the instructions and don't get LTE bands 4 or 7 with Virgin/Bell, does that mean the Chinese OPO doesn't have the required hardware after all for those bands? Maybe Band 7 is not available in my area but then 4 must be since I had LTE on my other phones. Or maybe my phone is just faulty. Would love to know if there is anyone successfully using a Chinese OPO on the Bell LTE network.

AT&T V10 (H900) has no band 17 support?????

I noticed GSM arena posted some variant specific specs for the V10. They stated that the H900 didn't have band 17 LTE, I thought this couldn't be possible. I checked AT&T's website, sure enough, no band 17. It has the lesser used band 29 (also 700mhz). Can anyone explain why this is? Where i live only band 17 LTE is available, so I hesitate to get the V10. Since both B17 and B29 are 700mhz, would the V10 be able to connect to band B17?
Here it is, straight from AT&T's website:

I made a post about this if you want to check it out. The short and sweet of it is that bands 12 and 17 are being merged, and they were always on the same frequency from the start, so having both bands is redundant. In other words, since band 12 is available, band 17 is as well, as confirmed by another user for the T-Mobile variant (but it still applies for the AT&T variant).
And if you're really skeptical, don't forget that you are entitled to a buyer's remorse in which the carrier must refund your purchase.

Thanks for the explanation ubergeek. So this means that even an older phone that only supported B17 will now work on, for example, t-mobiles band 12? Very cool!

An older phone that supports B12 can support B17 but only at the specified frequencies it's set at.

Are all variants the same lte band support?

LTE Bands on an N920T

Going by the specs I've seen on a number of tech sites, I've always thought that the LTE bands on most T-Mobile phones were limited to those that T-Mobile and AT&T use (4 and 12). However, when I ran "search for operators" I could see Verizon (and ATT + TMo) towers. Then I found this page at T-Mobile's own website that shows this:
InternationalQuad Band GSM; LTE: 1, 2, 3, 4, 5, 7, 8, 12, 20; UMTS: Band I (2100), Band II (1900), Band IV (1700/2100), Band V (850)​​
The UMTS bands obviously are TMo's, but LTE covers way more than they have deployed. So it would seem the N920T really has these bands? Perhaps it's because the chipset is Exynos.

You can see and change the band's from the dialer using *#2263#
I don't recommend changing them but you can look at the list.
I did change the default bands to LTE/WCDMA/GSM on mine for use on AT&T

That's interesting. When I execute that USSD, it shows way more bands than I quoted from TMo's spec list:

And this continues into the 40s, I just can't remember how to screencap the entire page. I am curious if they are all actual bands you can use, or (I would assume at this point) every possible LTE band there is. But it's a feature code I haven't seen before, so +thanks.

Well, after further digging in the *#2263# screens, this definitely looks like an international kind of phone.
If the settings are to be believed, there's also support for TD-SCDMA, which is an alternative to W-CDMA (and incompatible with it). That's used in China, which is a long way off from T-Mobile territory.
But that's great -- such an enormous frequency list is exactly what a flagship should offer. And it's probably no coincidence that this is an Exynos chipset, because other phones using Qualcomm seem to have restrictions in place for the US market.

T-Mobile USA

Anyone who already received their OP6 can me tell if they can connect to all the LTE bands including the new LTE band 71. Also how is the reception on the phone

I'll be getting mine tomorrow. So should be able to post up results then. But, the specs on the phone state band 71 is supported. It's just a matter of if 71 is in your area....

No band 71 in my area or I'd test that for you. Otherwise it is working perfectly on T-Mobile for me

I can't confirm what bands it was using, but I was able to get 120Mb/s via a LTE speedtest. I also confirmed VoLTE and WiFi calling work without issue.

No problems here with VoWiFi or VoLTE either on T-Mobile
And while doing a 2nd LTE speedtest I received a phone call, so did test while talking on the phone

How did you get WiFi calling, found it

So far no difference in signal strength or performance of the OnePlus 6 compared to my Samsung Galaxy S9 or iPhone X.

Not too bad. But how do you know band are we connect to?

download app called cellmapper https://play.google.com/store/apps/details?id=cellmapper.net.cellmapper&hl=en_US

I am on TMobile US and have been using WiFi calling and HD VoLTE. I haven't seen band 71 yet, but I don't know if it's in my area. Another app that works to check bands is LTE Discovery - https://play.google.com/store/apps/details?id=net.simplyadvanced.ltediscovery

I would also like to know if there is anything extra you have to do to turn on Wi-Fi calling.

Since I don't see the OnePlus 6 in the T-Mobile store, I'm assuming there is no T-Mobile-specific hardware/software version (as is typical with Samsung)?
Please confirm that OnePlus 6 could be bought from OnePlus store, and by following the above steps, all T-mobile features would be available? (Wi-Fi Calling, VoLTE, Tethering)

I bought my op6 from OnePlus store. I'm on T-Mobile in North Carolina and I enabled Volte & WiFi Calling via those steps. I see the tethering/mobile hotspot setting as well but I've not tested it.

Yes this phone connects to all of T-Mobiles towers it has even more bands then the T-Mobile s9+ that's why I got ride of that phone and got this one.

Teathering works
