LTE not working?! Manual Programming codez (updated)11-7

I got my Nexus 5 yesterday and finally got it working. I live right next to a LTE tower and I can't seem to get LTE.
1. Checked PRL
2 Checked Sim
3 Checked Profile
4. Called sprint
5. Checked network settings.
When i put the phone in airplane mode, and back off. It jumps to LTE for 2 seconds then 3g
Anyone having these issues ???

*manual re-fresh*
*#*#72786#*#*
after that, phone will reboot and "re-fresh network"
Also, my phone wen't into global mode, which you will need to change that back to LTE mode.
- Still isn't fixed ...
will report back ..

Manual Programming Code
*#*#675#*#*
edit: MDN = phone number
MSID: split

UPDATE
doing *#*#4636#*#* and selecting LTE only does indeed make LTE work both visually and functionally, with a loss of voice of course, but as soon as you go back to LTE/CDMA auto it'll require a reboot to take effect and LTE is once again not working.
(from sprint forums) - confirmed

I'm having these issues with Sprint as well. Thanks for your updates. I'll let you know if I learn anything.

You're Welcome,
Yes, this is very aggravating. My friends have LTE sprint phones and get LTE standing right next to me.
There is something wrong here! :/

On phone with sprint now, I hope they have an update.
Will report back.

Here is how I fixed it for myself on Sprint.
Settings > More > Mobile Networks > Network Mode
Change Network Mode from Global to LTE.
It will still connect to Evdo, ehrpd and Lte and switches between them as needed.
Luckily I haven't got hit with 1x since trying this out. My area has maybe one or two spots where I'd get 1x instead of ehrpd.
Settings hold after a reboot. I was driving to work today with my phone playing my music and it seemlessly switched between 3g and lte on it's own.

We are not having the same issues then. In post #1. I've referenced checking the network settings. I've done this over and over.
Lucky you!

I guess so because I was having that same initial problem you were where LTE would connect for a few seconds then when I tried to do anything with data it stalled out and went to 3g.

Mine does that too.
BUT, nothing in the settings has been able to fix this.

How long since you activated? Mine would not connect to lte at all until last night... about 30 hours after activation.
Now it connects fine. I tried everything including flashing the modems posted in dev, swapping sims, trying every different network config and nothing worked except lte only mode which then kills 3g and voice.

I too am having the exact same problem as the OP. I can change the setting from Global to LTE and the phone will connect to LTE for a few seconds before switching back to 3g.
I am coming from the Note 3 on Sprint that got great LTE here at home, about 16mb down and 4mb up but I am hoping this gets resolved quick.

I'm on T-Mobile and it favors sticking on HSPA+ instead of LTE. If LTE gets down to one bar, the phone decides it's time to switch back. Compare this behavior to my Nexus 4 and it would stick on LTE come hell or high water. I would stay on LTE while in the office and this phone refuses to even get on LTE in the office. I don't get it.
Some have suggested this is a "power saving" feature, but I call BS on this because my Nexus 4 wasn't even intended to have its LTE radio used and LTE really didn't impact my battery. It felt like it lasted the same as it did before I enabled LTE on it.

Possible Sprint Fix
Customer: Is the SIM device specific? I reused the one from my Note 3. I have seen other information that the SIM's for the Nexus 5 are device specific.
Mitchell C.: Yes, you can get a SIM for the Nexus from a nearest Sprint store. I can fix an appointment for you.
Customer: so they are device specific?
Mitchell C.: Yes, they are.
Mitchell C.: We've come across a lot of these issues today.
Customer: SO just to be clear, I need to ask for a SIM for the Nexus 5?
Mitchell C.: Absolutely.
Customer: ok
Customer: that should correct my connectivity problem?
Mitchell C.: Yes, every service will work fine after you get it.

Well, I got my sim card from a sprint store 2 days ago and I am still having issues. I have been emailing sprint care but no luck.
I hope they fix this soon! Maybe they gave me the wrong SIM? Idk

Doubtful Mitchell knows what he is talking about. People have used HTC One SIMS and GS4 sims and have LTE. But, today is the big day the Sprint phones go on sale. Will be interesting to see if any of those people have the issue.

Still stuck on 3G after activating around 72 hours ago.
To follow up on the Nexus 5's "special" SIM card. I'm also skeptical about this. I'm using a SIM from a GS4 (part #: SIMGLW206R) which is the same SIM mentioned in this post about activating the Nexus 5 on Sprint: http://qbking77.com/google-nexus-5/activate-nexus-5-sprint/.
However, I called a nearby Sprint store to ask if they had any SIM cards available. They said yes but when I mentioned the Nexus 5 the representative seemed to think there was some additional procedure for coupling the phone and the SIM. I don't know any more about this. Could be misinformation of course.

Shield LTE on T-Mobile issue.

Just got my Shield LTE today. This is my first tablet ever as well as my first unlocked device ever so I've never really had to mess with APN settings before. Long story short, I can connect and get HSPA+ ok but the speeds suck and no LTE at all. My Galaxy S5 can pick up LTE fine and get around 50Mbps down, but the Shield gets only about 5 down on HSPA+. When I search for network operators, my only choices are T-Mobile (2G/3G) and AT&T (2G/3G/4G). Any ideas as to why it can't find T-Mobile LTE network?

Does your phone work with LTE in the same spot? I got my tablet yesterday and moved the TMO SIM from by iPad to the Shield. Got LTE right away without doing anything with APNs. Depending on where you are, TMO LTE coverage is spotty.

Yes. My Galaxy S5 gets about 3 bars on LTE while sitting right next to my tablet that only has 2 bars on 3G. Just got off the phone with T-Mobile and they said they could see me connect to the LTE network and I did see LTE come up on the Shield for a moment but then it almost immediately dropped back HSPA+. I think its an issue with the tablet itself. I'm on hold with Nvidia now.

I'm still trying to get my Shield LTE activated on T-Mobile for the 200 MB free data for life deal. T-Mobile told me that their system saw the Shield's IMEI as a phone, not a tablet, and to bring it into a store so they can see that it is indeed a tablet.

The APN Settings came down by default for me and appeared correct with what I've searched online, but I'm having the same issue where I'm not getting LTE here in the PHX market, in all the places my phone gets full healthy LTE.
I don't want to complain about my H+ signal, but it's just not cutting the mustard if you will.
You find/hear anything useful here Hoju?

I'm seeing the same issue With LTE/Tmobile alsnly HSPA+

I've been in contact with Nvidia support since last week and they have had me send them numorous diagnostic files and bug reports. From what I can tell, the Shield is using NVIDIA
's Icera i500 modem which can be thoroughly tweaked through software updates. I'm hoping this issue can be resolved with such an update. Nvidia level 2 support told me that I was the first case of this reported, so I urge everyone suffering from this issue to contact support so they can see that the problem is not an isolated incident. I'm hoping to hear back from them today regarding this. I will update the thread when I do.

T-Mobile setup my imei number as an iPad to activate sim and didn't give me the pin, called T-Mobile and got it fixed, the pin turned out to be 1234, once he fixed the imei and changed pin, internet started working well and LTE is working as well. Also logged into T-Mobile.com/connectme I'm not sure if that's required but that's where you can buy more data. Hope that helps someone

Hi there, T-Mobile retail dealer here. I've tried 4 different T-Mobile sim cards (2 $50 simple choice plans, 2 $70 simple choice plans) along with 4 of their MVNO's sim cards (Univision Mobile, Straight Talk, Ultra Mobile, Lyca Mobile) and they all had LTE.
With all of the T-Mobile sim cards, the standard APN that's loaded in (fast.t-mobile.com) works perfectly for me.
For the MVNOs, using their respective APNs allowed for LTE, while using "fast.t-mobile.com" on those services only gave me HSPA+
I'm also located right outside of Philadelphia. Not really a populous area but we have good coverage with T-Mobile around here.
Hope this helped.

I also just added ro.ril.fast.dormancy.rule=0 to my build.prop, result so far is stable connection on h+. Without that it was flipping between 3g and h+ constantly and connection was unstable. ive been streaming music and it did change back to 3g, but not back and fourth like before, ill keep an eye on it.
maybe i spoke to soon, i still see it switching. Ill update after some more testing if this did anything or not for me.

Not really, guess it was a placebo effect at first and just happened to stay on h+ for a while. from what i have read over the last few days is that on t-mobile's network it switches to 3g to save battery. I just removed the line i added, streaming music right now and just got a drop out. If someone knows or comes up with a way to force it on h+ I would happy, i could care less about battery savings if i just have this thing on my desk plugged in all day.
I got some time today, going to try staying off of wifi all day and see how it acts, might try a couple things if i can find some other options to test. if i find something ill let ya know.

Thanks for the response. I ended up exchanging mine with a new one that I just received last night. Right now I'm still testing and hopeful it will shape up, mine would drop from H+ to Edge, I do get LTE from time to time but it's very sparse. So far the replacement is doing well but i'm more and more convinced this is a radio issue as the tablet was really certified on AT&T. I've filed a ticket on my old one with Nvidia, no eta on a fix. Anyone that's seeing this go through nvidia support and file a ticket. Hopefully they can get it fixed in the next OTA.

I, too, only get H+ signal from TMO on my Shield. While it's normally fast, it sometimes drops and goes to E(DGE) or none at all.
EDIT: TMO could find nothing on their end via online chat. I'm going to test the SIM in another LTE device, and see if its a SIM issue. Waiting to hear back from NVIDIA. Really hoping our coming-soon 5.0 update fixes this!
EDIT 2: I just heard back from them that the TMO issue is an open bug "and will be fixed in a future update".

shield vs lte?
Yours at least connects, mine wont even do that I probably go to local branch again tomorrow if things wont change by the morning. I hope it works, but i cant activate the sim. Shield recognizes the card, under connections it says T-mobile but every time i turn off WiFi and try to activate the sim via cellular data, it keep telling me theres no connection yet i have 2 bars of their signal

So this means that I could but the 30 dollar a month plan? 5GB data, 100 minutes and unlimited texts?

Did anyone that was having a problem with LTE ever get it resolved? I just picked up the LTE version of the Shield tablet and have yet to see LTE and my phone is getting it fine. I hope a solution was found.

Yep, I'd be interested as well. I got that tablet since a few months and have problems with the radio too. I'm running LingeageOS 14.1. The latest few builds didn't even find the sim card anymore. Today I got back to stock rom for testing. Sim card is there, but it loses the radio connection every few seconds.

I just tried T-Mobile: works like a charm. It seems like Vodafone is causing the trouble. I've tried two different SIM cards and have the problem with both. Country: Germany.

What LTE band is your phone connecting to? I'm assuming you are T-Mobile? If you're in a band 12 area you might be out of luch as the North American version supports bands 2, 4, 5, 17, 7.

Dropped calls when going from lte to hspa/hspa+

Just recently I've noticed that I drop calls when I'm on a LTE signal. It is very annoying. Is anyone else having this problem. Does anybody have any idea what is going on here. I notice if I have a HSPA/HSPA+ signal I don't drop calls.
Actually I noticed if I turn LTE off I don't drop calls at all. I am on the AT&T network if that matters.

Same network, similar but different issue. Within the last couple of days my phone now hangs up the call after a few seconds. Sitting at my desk, signal strength is in the -70's, a call comes in and the LTE symbol drops to HSPA or HSPA+, (good so far) then no icon shows then the signal indicator goes completely blank, the call hangs up then after a brief pause the phone reconnects to LTE. I'm completely stock, running the latest CM 11S and I've tried everything I can think of to figure out the problem. I've wiped the phone, stopped using Google Voice, I have not added new apps lately, swapped out my SIM card into my OPPO Find 7A and it works flawlessly...I'm at a loss. At this point pre-ordering the N6 can't come soon enough for me.

That is actually what happens to me but I couldn't explain it as well. I'm on a cm11 rom.
I'm wondering if it has something to do with AT&T.

Have you updated to 38r?

Yup, updated as soon as it came out so it's been a few week now for me. Had the phone since early June, this has been my real first issue I can't overcome....pissed

Have you tried to turn off lte and just run it on 3g?

No and at this point I kind of don't care since I'm getting the N6 as soon as it launches. I can make due with my Find 7A for a few more weeks. In some regards it's actually better as a phone than my OPO. Probably going up on Swappa soon!

I was just wondering if yours is acting the same way with the lte deactivated.

Yep had this since i got the phone, sometimes on lte it just wont let me call and say " mobile network unavailable ", been on 3g for a long time and haven't had any problems.
probably because lte coverage where i live is meh.

Yeah but WTF, this is bull**** to have an LTE phone and force it on 3G. I'll put the SIM card back in and try on 3G for a bit but if I get frustrated and throw the thing out the window its on you : -)
---------- Post added at 05:48 PM ---------- Previous post was at 05:19 PM ----------
So far so good when selecting 3G the phone holds the HSPA or HSPA+ signal.

Looks like on the 1 + forums there's a lot of people having the same problem. Someone said it's going to get fixed in the next ota. Looks like the last update 38r boogered something up.

I just want to say that for those who are not aware if your phone shows low LTE signal, that has absolutely nothing to do with voice services and the quality of voice services you might get. As soon as you type in a number and hit call the phone automatically hands off connection from LTE to HSPA or 3g to make the call. This is 100% normal. VoLTE is not available on our phone nor is it activated on Tmobile yet I dont think but likely soon.
I expect that once we get official Lollipop and tmobile works out their nexus wifi calling dealio they got going on then we will also be getting the same wifi calling and texting magic. No need to get freaked out people.

I was aware that there was no Volte. I know that it is normal to go to 3g but it never dropped a call doing that before. I must disable lte so the call doesn't drop. I know this only because I have an att microcell and it forces my phone to 3g for full 5 bar voice service.

Yea microcells do weird things, the hand offs are messed up in general in android I think with them. Sorry thought you were on tmobile. Still not use to being in a forum with an unlocked phone

Birdsfan or others,
By chance did you have wifi off? I just been doing some testing and noticed this:
wifi on/lte on = no dropped calls
wifi off/lte on = dropped calls
wifi off/lte off(3g only) = no dropped calls
If you want lte activated and make phone calls without it dropping calls then turn on wifi?
Check it out, see if it works.

I found the exact same results as tdamocles

Left the house and learned that there needs to be wifi in connected state for calls not to drop.

I just started having the same issue, exactly as described.
WiFi + LTE, no prob.
H/H+, no prob.
LTE without WiFi, phone switches to H/H+ and connects for about 2 seconds then hangs up while the signal icon goes blank, then back to LTE.
I tried reflashing stock 11S with a clean wipe, 38R.
I tried the latest nightly with a clean wipe.
Really at a loss here.

I really like the phone and CM but I need my phone to work as a phone....I'm done I'm pre-ordering the Nexus 6 Wednesday.

I dunno, I just tried reverting, via clean install, to 33r and the issue persists (did NOT go away).
Makes me worried it's a hardware thing.

No more LTE connection after upgrading to cm12.

As the title suggests, I no longer have connection to LTE services, beforehand I could get full signals.
I downgraded back to cm11s, and installed the previous XNPH44 modem, still no luck.
I have also tried XNPH33, 30 and 25. I have even tried the ColorOS modem as well as the M9.
Furthermore, I have tried the *#*# secret settings, currently it is on LTE/WCDMA. I can reach H+ connectivity but still not LTE.
I live in Australia, and am with Vodafone. Meaning Band 4 is the one I need to connect to, (1850mhz I think.)
Please advise on what I should try next.
Thanks.

Haha, you're not much help are you.
As written above I used to get full LTE coverage in my area. I even included the LTE band that the LTE broadcasts on.
It is also confirmed on Vodafone's website if you want to have a look.

Is your issue similar to this thread or do you simple just not have LTE, only and never get it on CM12?

Thank you!!! I have had my OnePlus One on cm 12s for about a week and the LTE has never worked since I upgraded. Just H+ works. And more than that - it keeps turning the H+ (3G) on and off which I think it's really killing my battery life!!! I have been trying loads of things to get my battery life back to what it used to, huhuhu. Turns out my APN got set to T-mobile somehow! I have Red Pocket mobile GSMT which runs on T-mobile and I always got LTE with it till the upgrade. (I'm in USA.) Just had to switch the APN from T-mobile back to Red Pocket 4G. The LTE works again and never cuts in and out!
:good: :good: Thank you! :good: :good:

LOST my LTE connectivity
LOST my LTE connectivity after upgrading my oneplus to CM12,my oneplus originaly came with chinese color os ,,after i install cm11 then cm12,,I put LTE only mode using *#*#4636#*#*,no signal,Im in srilanka ,using Dialog LTE band3 1800mhz

Same situation, with Vodafone in Italy.
Maybe the last OTA upgrade introduced this issue.

OP6 connectivity issues

Hello,
I have for the past 1 and a half years an OnePlus 6 which since the start I have an issue related to 3/4G speed outside of my home country.
Now please don't start about turning on roaming in order to have internet. I have done that since I've got my phone.
I do have internet, however the speed is absolutely terrible. It is always on GPRS and goes with bytes per second. Texting goes sort of alright, loading sending images takes up to several minutes. Beforehand I had an iPhone and I used to have 3/4G with the same simcard.
I also have a work sim which on my work cell has a good range but on my OnePlus.. again I get hooked to GPRS and it goes on a terrible slow rate.
I have reinstalled my phone several times. Went from Android 9 to 10 and the issue is still there.
It also isn't country related because I have this issue in.. Germany France United Kingdom Italy Austria Hungary Poland. More countries I was not able to test yet sadly.
Does anyone has an idea what this might be? Is this a setting somewhere what is enabled on default? I know multiple OP6 users with the same provider as mine i compared some phone settings and they have a normal speed while I don't. So actually I don't know anymore what it could be.

I also have a work sim which on my work cell has a good range but on my OnePlus.. again I get hooked to GPRS and it goes on a terrible slow rate.
I have reinstalled my phone several times. Went from Android 9 to 10 and the issue is still there.
It also isn't country related because I have this issue in.. Germany France United Kingdom Italy Austria Hungary Poland. More countries I was not able to test yet sadly.
Does anyone has an idea what this might be? Is this a setting somewhere what is enabled on default? I know multiple OP6 users with the same provider as mine i compared some phone settings and they have a normal speed while I don't. So actually I don't know anymore what it could be.

Try forcing your phone to LTE Only
Dial *#*#4636#*#*
Go to phone information
Set preferred network type to LTE Only for 4G
or LTE/WCDMA for 4G/3G
In LTE Only mode, you may or may not be able to receive or make calls.

I don't see any error. It is working correctly as I can see. Your data is off. It's UMTS that is likely to be H+ network i.e. 3G.

Also Phone 0 is your sim 1 and Phone 1 is sim 2, FYI just in case.

I know everything looks fine. My connection says R
However I just don't have any internet with either sim ad soon as I go over the border.
If I put my sim in another person's phone it works. Their sim in mine nope.

Some networks doesn't provide data services while in roaming.
As you say it works in other phone. It seems your device is faulty.
You said you reinstalled Android 9 and 10. How did you do that?
Did you use MsmDownload Tool? Or just zip flashing? Or fastboot rom?
I would suggest to backup all data and completely wipe your phone using MsmDownload Tool.
If you've already done that then I'm afraid Network Module/Chip (usually referred as Modem) is faulty.
You will have to visit service center or repair shop to know exact fault.
