[Q] One+1 and T mobile LTE

I just got my One+ and i had notice that I do not have LTE H+ only. My wife's nexus has LTE in the same area where Oneplus does not have it. I Did bunch of research and I was under impression that this phone does support T mobile LTE - was I wrong or the phone is broken?
please help

sure it does if when doing your research like I did on mine I see it works on Band 4 which is T-Mobiles band for LTE. I get speeds up to 36dl and 19up with my ONe.
What are your speeds? Does your wifes Nexus show H+ and 3g symbols?

Nexus shows LTE when my phone shows H+
I used the app that you send the link for and when One+ has H+ on it app tells me that i am on HSPA 42.2 MBS
I will need to install same app on Nexus and check it out on that phone
What symbol do you get on your oneplus one when its on LTE? is it 4G? LTE? H?
thanks

I am sorry I may of had stock rom for like an hour... I think it was 4g symbol but I have a custom rom and it shows LTE. I noticed that some of the same lines in the build.prop for LTE on my nexus was not in here for my OPO.
What state are you in?

I am in NJ
But I think I got it figured out - You are right it works in LTE - when i had 4G on screen i used the app you send me link for and that app shows LTE as network. So the bottom line is that 4G stands for LTE in stock rom and it is possible that Nexus has a stronger radio than One so in some areas i do not get LTE.
Anyway Thanks a Lot for your help - got a little worried ( Got the phone just yesterday). I think i will keep it stock for a little while before i will root it

The radio performance seems the same for me as my N5, I'm living in NYC.
Do note that "LTE" on a Nexus 5 is displayed as"4G" on the OnePlus One. Ensure that your APN is on T-Mobile 4G LTE IPv6 (fast.t-mobile.com), for some reason when I started my phone it was on MetroPCS instead.

nah root it its more fun that way and fyi they just came out with an update to 4.4.4 stock from what I have been reading. I saw this posted in earlier.... I guess you will be getting an update soon.
One suggestion if you plan on rooting and unlocking bootloader I suggest doing it now since it will wipe everything when rooting... There is a method where you wont lose data but it will not unlock your bootloader

To OP: How old is your SIM card? Have you ever received LTE signal on a previous device? I receive LTE on TMobile 4G perfectly fine, I just wish the "4G" showed up as "LTE" as my Nexus 5 did. I guess I could personally go skin it to say LTE instead but its just cosmetics.
And I completely agree with unlocking the bootloader, even if OP doesn't have any intentions to rooting/flashing, at least do it now so when you do decide to do it then you will be able to back everything up without having your device get wiped.
Edit: OP also go into dialer and type in *#*#4636#*#* then go into phone information -> scroll down -> under set preferred network type: LTE/GSM auto (PRL).

I thought the same thing (coming from a Nexus 5). I was worried that the OnePlus One did not support LTE but it definitely does. For some reason Cyanogen did not include a separate LTE icon as what's found on the Nexus 5 and most other LTE capable phones.

For sure its weird how they didn't adopt "LTE" and used "4G" instead. You can always go and change it to "LTE" with some apk hacking. Pretty easy to do.

So does your phone get "4G" now? You can verify in Settings -> About Phone -> Status -> Mobile network type -> should be LTE if the top right says "4G"
The best way to unlock/root is to NOT use a toolkit. Yeah a toolkit is easier, but honestly unlocking a bootloader is not hard and the skills you obtain by doing it yourself are important. You won't lose warranty, you can always relock it and use the bit mod and OnePlus will never know. Plus OnePlus encourages the whole custom rom scene since thats why they have a Development forum on their official forums.

I called AT&T to have the IMEI changed over to the OPO since I was on the Nexus5. CyanogenMod doesn't technically come with LTE icon, personally I can careless but it does look nice at top lol. And you're correct on my device under Mobile Network Type it shows LTE but icon on top shows 4G.

4G is LTE
H+ is HSPA+
3G is ... 3G
edge is edge :crying:
The first speed test in my sig is my LTE speeds using my OPO... Pretty typical, maybe a little faster than my old Galaxy Note 2. :good:

how does one change it to the LTE symbol?

I'm just curious. If you know 4G means LTE, whats the difference if it says LTE? Not trying to be an A-hole...just curious.

If you run the CM11 nightlies on the OnePlus One the phone will show LTE in an LTE area. Only the stock CM11S shows LTE as 4G.

I would think that people on xda are more well informed.
Carriers like to change the official terms to make you "buy" into a "technological" leap.
Most of the roms outside North America uses 4G (instead of LTE). This is all about marketing.
HSPA(+) are 3rd generation networks while LTE is the 4th generation.
back in the day:
iPhone = edge speed 2.75G
iPhone 3G = HSPA 3G (7.2) speed
iPhone 4 = HSPA+ 3.5G (carriers in north america tried really hard to change this to 4G)
iPhone 5 = LTE 4G

I agree fully with Line 1 - especially here we should do more homework before posting...

my oneplus signal is terrible compared to my n5
Sent from my One using XDA Premium 4 mobile app

mine is better then g2. Do note that your phone may or may not have the bands your provider has for lte. This you should have checked before you got the phone.
Also delete apn and reboot.
If it works better something went wrong there. If it doesnt check your providers website if setings are all correct.
If they are you might need a new sim/ or lte enabled via your provider.

[Q] F350S on AT&T in Ohio No 3g/LTE

I've been scouring the internet trying to find a solution. I've been wanting this for a while. I did my research to figure out which model of the G pro2 worked with AT&T. It arrives and now nothing. I'm only getting G not 3g or LTE. I am a bit new to smart phones. I've tried everything I can think of. Am I using the wrong apn settings? Is there something in the band selection menu I'm missing. I'm at a complete loss what am I doing wrong?

In Dialer 5754#*350# and activate your Bands or 5457#*350#

Still no dice
I've gone into the menu and specifically selected the required bands but still not dice. I went into the lte band selection menu. Is there another menu I should go into?

I have yet to root my phone I am a bit of a newb when it comes to things like this. I do plan on rooting it and giving it a Skin that has a lot more english. I have done this I selected bands 17 and 5 for lte and 850, 1900 for wcdma and gsm. In the Band Selection Menu. Should I be doing anything with WCDMA Channel, LTE Channel, WCDMA Security, RAT mode, RRC Version, SMS MO Domain, Service Domain, any specific APN setting what is it on your wife's phone, EF file edit, HSPDA category, HSUPA category, GCF Test, OEM RAD Settings, SKT Auto Test, IRS Setting, CA Setting, LTE 3GPP Rel. VER. or anything else I am missing?

I've determined that my phone is a very good fake
IDK if this is real issue but if some does have this problem and comes up with a solution. Please post it here I was beyond frustrated and hope this problem can be solved for someone.

Try going back to 4.4 and using LTE

Try taking your phone to an AT&T store and explain it to them. They will install a new SIM card and associate it with your IMEI #. Then you will have LTE!

I'm sitting in front of a Tmo store waiting for them to open and see where that goes. Hey guys how's battery life with this device. For what ever reason when I did put a Tmo sim in this phone it got only 3g now the chip was a nano from my nexus 6 using a quality adapter but holy crap I've never seen a phone eat a better like Godzilla. Hell it killed the device in like 3hrs. Although when removing the sim it seems to go normal using just WiFi connection. Very strange device behavior. Does this phone have bad battery life in its normal state? Since I am a huge "Big Screen" fanatic I would probably just get the extended battery from the Japan guys on amazon. Your thoughts?

1. You Should have an LTE Sim
2. LTE Data service Should be enabled on It.
3. You have correct APN settings From your Carrier
4. You should be in LTE Coverage Area
Now go to Hidden Menu of the Phone. 5457#*350#
in WCDMA Service Menu
1. Slecect WCDMA Channel and Slecect Full
2. In LTE Channel Select your Preffered band ( You should Knew your LTE band or ask from Carrier)
3. In Band Selection Select your bands or select automatic
4. In RAT Mode select automatic
5. Check mar APN Edit Function.
You can also increase RRC Version, HSDPA Category, HSUPA Category and LTE 3GPP Rel. Ver. if your carrier supports you can get higher speeds.
Reboot Again
Press the Thanx Button

OnePlus One fully stock - T-Mobile - no signal/carrier connection 52% of the time

My OnePlus One is on latest cyanogen 12.1, completely stock and unrooted. I am noticing high battery drain on cell stand by (42%)
and of that 52% of the time there is no connection to carrier.
Is there a fix for this issue? My wife's Note Edge (SM-N915G on stock KitKat) has no signal issues with T-Mobile. but my OnePlus One show no connection most of the time. Is this a CM12.1 issue or is this a known issue with OPO and T-Mobile combination?
Appreciate the help.

Which baseband?

This could just be because of where you're located. The OPO only supports one of T-Mobile's LTE bands, band 4, while the Galaxy Note Edge supports all three, including band 12, which has much greater range and building penetration.
All of the recent T-Mobile commercials touting improved coverage area and better building penetration are based off of using band 12 on their newer devices which support VOLTE (voice over LTE). All of their new towers incorporate this band in areas that previously had little or no coverage (especially rural and suburban).
If you're in an outlying area with poor band 4 coverage your handset will be constantly trying to lock in on the weak signal and shifting from 3G, 4G, and LTE. Doing this also greatly reduces data transmission speed and reduces battery life.
If you're in an urban area with strong signal acquisition, then forget what I just said, you have another issue.
Hope this helps.

i used OPO on tmobile and it worked fine, depends on many factors including location, time of day and of course the bands used by the device.

I see from your profile that you reside in the UK. The OP doesn't list his, so I'm operating under the assumption that he's here in the states. My observations and comments in the post above yours, are strictly based on what I know about this device and with T-Mobile USA, as I'm unfamiliar with its operations in other countries.

Apologies, should have included location detail. This OPO is in Austin, tx so its metro area.
Baseband: DI.3.0c6-00241-m8974aaaaanazm-1

You might, but I can't say for sure. The OPO supports 2 of the 3 bands AT&T utilizes, band 4 (like T-Mobile) and band 17. So you have more of a chance. Bear in mind, that AT&T is considerably more expensive than T-Mobile and that they have roaming agreements with each other, where if you can't get any signal for telephony you'll roam off the other's network.
Generally speaking AT&T has more coverage, because it's an older more mature company with a more established infrastructure. T-Mobile is more of an upstart, but is rapidly expanding with a newer technology. Like I said in the previous post, explaining why your wife's Note got so much better reception, newer T-Mobile devices which support all 3 LTE bands (2,4, & 12) get better reception and probably twice the coverage than what is possible with the OPO.
I hope this helps explains things.

Since stock 12.1 update, I've noticed mobile network keeps dropping and in return draining the battery quickly.
Thinking it's the update, I've installed custom 12.1 ROM, but the problem persisted.

Goto APN settings, take note of current APN's.

Save then reboot phone.

Scroll down to LTE issues and try the method described. Just note that it suggest deleting other APN, but I recommend against it because it can interfere with roaming.

All phones can now get WiFi calling. Just download digits and sync it. Download it on your main driver and sync it. You can use the DIGITS to call using WiFi from any device using your number.

? How to get LTE speed on US LTE tablet running ROW LTE Image?

Hi folks,
I've got the US LTE original Shield tablet, which is the replacement that NVidia sent me for my original "pyro edition" tablet. Since ATT haven't released the Nougat (Android 7, software package 5.0 or 5.1) builds for this tablet, but the ROW tablets are able to get this update, I flashed my tablet using adb/fastboot with the full ROW 5.0 package downloaded from the NVidia site. I then connected to WIFI, and let it pull down the 5.1 update. Factory reset, flash TWRP, rooted with SuperSU. Easy peasy. Then I set up the tablet with my accounts and such.
Based on good info from user @Son-j I made two build.prop edits, changing ro.build.flavor to wx_na_do-user (was wx_un_do-user) and ro.product.name to wx_na_do (was wx_un_do). This changed the reported signal type from H+ to 4G. Unfortunately I'm having trouble finding the thread where he suggested doing this. I think it was on the geforce web forum.
The only problem I've found so far is that I'm not getting LTE speeds. I was in Chicago for a couple days, in an area with strong LTE signal, and my other devices were reporting LTE and getting ~20Mbps down / 10+ Mbps up. My Shield was pulling maybe 8 Mbps down at best , and 1-2 Mbps up. At home in my suburban location, the difference is negligible (most devices here do 5 Mbps down / 1 Mbps up, LTE or 4G).
Still, I'd like to fix this if possible. Are there further edits or flashings that will let my US device running the ROW build get LTE? I have gone in and verified that my APN settings are the recommended ones from ATT. These showed up automatically, and matched the ATT recommendations.
Thanks in advance!

Hi I'm not sure but I there was a thread here in XDA that says it's still difficult to change the LTE (RoW to US, and vice versa) bands because developers couldn't find yet which part of the code to modify... It's not also confirmed if it is indeed possible to change the LTE bands to support.
So basically, flashing RoW LTE on US LTE device will still result in US-LTE supported bands. That's what I understood.
But what you did is quite a revelation. Can anyone else confirm that modifying the build prop will work? Boy I'm excited!

Hi @Son-j -
Thanks! Do you happen to remember which thread had those two buildprop edits? I found them after seeing a post from you a few days ago, but now I can't find it at all. My google mojo has fled me.
I'd like to have a link there so others can see the original source.
It would be nice to get LTE speed, if someone knows how, but most places where I use the tablet don't have super fast LTE, so the difference for me isn't enough to make me downgrade to the marshmallow US LTE build. I'll stick with nougat for now, and hope eventually to get full speed. Who knows, maybe ATT will eventually release the 5.1 US LTE build...

For clarity here is the set of APN settings I'm using. I'm going with the column in the center at the bottom for Tablets:
https://www.att.com/esupport/article.html#!/wireless/KM1062162
All of this was correctly entered by default except I did need to edit two keys:
APN was listed as broadband instead of Broadband (yes, I'm picky, but wanted to match case)
APN type was listed as just default. I edited it to match the listed setting of: default,mms,supl,hipri,fota
Also I'm set to LTE for "Preferred network type"

Ok I think there's a misunderstanding. Uhm, I'm trying to look for the related posts here at the Nvidia threads but it seems to have disappeared.
Just to set something straight, LTE speed is influenced by:
1. LTE device with specific supported LTE bands
2. LTE sim
3. Location with LTE signals
I take it that for your specific device - US LTE Shield Tablet (just like mine) - you satisfy all 3.
For the record, flashing RoW LTE on our US device won't change the supported LTE bands (check baseband code in About Tablet section of settings). So if you used to have AT&T LTE speeds/signals using US LTE ROMs, it shouldn't change if you flashed RoW LTE ROM on the same device.
We are speculating though that there might be a way, software/firmware speaking. We are hoping it's not hardware-baked.

Thanks Son-j. It kind of freaks me out that just a week ago I found the thread that recommended those two changes in buildprop, but now I can't find it, and apparently neither can you! So maybe I'm not crazy, since it's more than just me having problems finding it.
Anyway, yes, I used to get the LTE indicator on the tablet, when in an area that has decent reception of those bands. At my workplace, which is a building built like a Faraday cage, we can get only ATT service, via repeaters spread throughout the building (I switched from Verizon in part due to this). Phones almost always report ~3 bars of LTE in places I usually find myself within the building. However, speeds tend to be <10 Mbps (tested using Speedtest.net from either my phone or tablet). So, despite getting "LTE service" there (prior to my software update), the speeds were nothing so great. For this reason, I'm not TOO worked up that my US tablet running ROW software isn't reporting LTE... most places where I use the tablet don't have blazing fast LTE, and the difference between the 4G service it actually gets and the LTE it "used to get" is not that great.
I would like to fix the problem if possible, but it's not a critical thing, and I may just put it on the back burner until the US LTE 5.1 image comes out, then flash back to that. I've got lots of other fish to fry these days.
Always interesting discussion. Thanks Son-j!

If it's just a speed issue, that will be the provider's end. If it's a signal issue, that's device problem.
It's possible to get an LTE signal but with HSPA speed in some areas.

There is an app called LTE Discovery. It will tell you which band it is currently connected to. I've got it on my tablet on T-Mobile. I am having problems with it connecting to anything other than 3G. But I have read others with the Shield tablet having similar problems with T-Mobile.

Thanks @caseyatbt,
I was unaware of that app. I downloaded it on my phone (which gets LTE just fine at my house, most of the time) and it reports all kinds of fun stuff about the LTE signal it's connected to. On the US Shield tablet running ROW stock, this is what I get, which frankly makes me think the tablet is connecting via CDMA of all things, despite having chosen all the correct options in the Settings / Mobile section:

The fact that my radio seems to be connecting to WCDMA instead of GSM is kinda freaking me out, folks.
I'm tempted to try flashing the US LTE device Marshmallow recovery image, and see if that fixes it. I understand the flashes don't change the baseband, but since I flashed 5.0 and the the device did an OTA update to 5.1, that might have changed the baseband, eh?
So, if me flashing the marshmallow files doesn't fix it, I might reflash an earlier edition and let it OTA to latest edition, which presumably would install correct "latest" baseband for the model.
We'll see ... I'm still not committed to one direction or another.
Marc

OK, I just flashed the 4.4.0 version of Marshmallow. (full flash of all Nvidia recovery image files). After letting it reboot the first time, it checked for update and found none, as expected.
NO LTE. Downloded the LTE Discovery app, and it still only sees WCDMA signals. Uggh.
Now I'm going to install the 4.3, and let it OTA to 4.4, and hope that refreshes the modem/radio. If anybody is following this, wish me luck!
EDIT: OK, I'm in idiot mode. I downloaded what I thought was the 4.3 US LTE image and it was actually the 4.3 ROW image. I didn't notice this until after flashing, and seeing the H+ icon, and noticing lack of ATT usage tracking app. Oops.
I don't see the 4.3 US LTE image on the site; I'm now downloading the 4.1 image, and will do OTA updates from there, checking as I go how which signal my radio is getting.

No Joy.
I flashed US LTE 4.1 image. AFter the flash, LTE Discovery still reports just HSPA+ signal from WCDMA towers. I then let it take the OTA for 4.4... the latest available for the US LTE tablet, and after it ran through its update process, I'm still on WCDMA.
Uggh. I doubt there's any WCDMA signal where I work so I may have killed my tablet, at least as far as using it at work is concerned.
I'm sure there IS a path back, I just can't imagine what it might be, at the moment. I'll start a new thread to be more specific to this current problem.
Sigh.

Eventually found that thread with the buildprop changes, see here if interested or if you ever need to find it.

I just checked my Shield on T-Mobile. In the same area on LTE Discovery that yours says W-CDMA mine says the same thing (under Neighbor Cells). When you scroll to the bottom, what does it say for carrier?

Carrier: AT&T (310410)

Here are screen shots of my sim status (personal details redacted) and the LTE discovery window:

I am thinking that it is possible that W-CDMA doesn't mean what we think it means. It shows you connected to AT&T so you are not on someone elses network.

I talked to ATT. It's sort of their backup network, not available everywhere. My other devices definitely show LTE. Will post a screen so from my phone a bit later which shows that.

Here are some pictures taken from my phone, which is working properly. In settings, you can see the LTE network type and in the LTE Discovery app screen capture, all the LTE towers.
ATT maintains a "vestigial" WCDMA to allow some level of connectivity by devices that don't have GSM/LTE, but it's not everywhere and it's pretty slow.
The Shield used to show LTE in the Settings Cellular network type, as well as giving the LTE icon, when appropriate. Now it's just HSPA. Sigh.

My T-Mobile phone shows similar to your phone with LTE. T-Mobile must have a similar vestigial WCDMA that is showing up on my tablet. I still haven't found anyone that was able to get T-Mobile LTE working after it was only giving them 3G and HSPA. I have heard it either worked or it didn't.

Can't make or receive calls from a few select areas.

Strange problem. I tried researching this problem and found nothing.
My OPO works just fine at everywhere except home and another location a few miles away from my home. At these places I can't make or receive phone calls. Data works fine. I flashed the newest resurrection remix, with full wipe. I also tried flashing 3 different modems.
I called T-Mobile and presented them with the problem and they said my phone many be too old and possibly not support T-Mobiles' new LTE bands. So, I asked what band am I receiving at home and they Dont know... I dropped down to prefer 3g and still no luck.
Anyone with a similar experience or may know what I'm dealing with please help. I still love my OPO and would prefer to not buy a new phone.

You might not be able to use Lte perfectly on T-mobile(as they already said) since it uses LTE band 12 mostly which OPO doesn't supports..though I guess 3G should work fine.
Also,I guess T-Mobile uses VoLTE to place calls,which again,OPO doesn't support.
Can you list out the modems/firmwares which you've tried so far?

4.0.1.c7-0013.zip

Thanks for the info. I guess its time to buy another phone.

Can't you just change your Carrier instead?

LTE discovery app shows i am connected to LTE Band 4. 3 of 4 signal bars. Is it possible that t-mobile uses band 4 for data and band 12 for voice?

I am in USA. The next biggest carrier is Verizon which dont work on OPO. Metro PCS is the same as tmobile. I am not going ATT. OPO dont work on Sprint either.

Yes,it could be possible.
Good luck for your new device.
