[Q] LTE - Nexus 5 Q&A, Help & Troubleshooting

Hey guys,
I'm hoping someone can help me because 3 hours later, 2 Google Play representatives and 3 online chat customer service O2 workers couldn't help me out.
I have a Nexus 5 and I'm on O2 here in Berlin, Germany. My Network Mode is switched to "4G" and my APN (as per another post) is correct. The plan is an activated LTE and the coverage in my neighbourhood is perfect according to the guy at O2.
I still don't seem to be getting LTE on my phone. Neither the LTE logo above the signal bars, nor the speeds (supposedly 50 Mbps).
Thanks.

Tried removing and reinserting the simcard? Or go to settings/mobile network and change from LTE to 3G and after that go back to LTE and reboot.

Tried, failed.

Just removed SIM, asked me to restart the phone...still on "H".
Every time I switch the Network Mode from 3G to 4G it automatically changes the APN to another option.

Go to a O2 store nearby and have them check the settings on the phone and get LTE working.

Thank you

So I visited the O2 shop and the guy had absolutely NO idea what to do. He barely even knew what the Nexus 5 was!
He first thought it was a SIM issue but since the SIM is only 2 months old, it's 100% LTE compatible.
One more try with the online chat help and he said my area had a weak LTE signal and I should go somewhere else and try it.
I haven't done that yet but will try later today.

So you have to move to get LTE working Does O2 provide you with a suitable place to live in? What a stupid response from the guy. If they offer LTE they have also have to deliver it imo!

So apparently they're setting up a tower next to my apartment on the exact same day I'm moving out. -_- I've been frustrated all day trying to get this to work. I'll travel to one of the upscale areas now and see if it works. I don't need 4G at home anyway, it's only for when I'm out.
Will be back with updates later tonight.

Issue Resolved

So apparently the problem was the coverage in my area. The more heavily populated and "cooler" parts of Berlin have a fully functional super fast LTE.

[Q] Desire s stuck on gsm only

Hi there,
Hopefully someone can help because my brain is melting here. Basically I spoke to orange customer services the other day because of totally poor signal. He told me to switch to GSM only, which was fine and I know it can improve your phone signal. The thing is, it's now stuck on there, whenever I try to change it to WCDMA it automatically switches back to GSM?
Any body got any ideas?
Cheers
Ian

I feel your pain. I am also a long-suffering Orange customer. Everything was fine until they climb into bed with T-Mobile. Since then my signal has been so erratic I simply can't trust things like Google Maps to work as navigation. Orange have left me stranded twice bombing out the 3G just as I need it to get home.
Anyway, how exactly did you switch to GSM only? There are a couple of ways of doing it.
Menu> Settings> Wireless & Networks> Mobile Networks> Network Mode = GSM/WCDMA auto.
I suspect it was this one. If this is the method that is changing back to GSM, then try this one;
Open you dialer, and dial *#*#4636#*#*
This will open a hidden testing menu, from this select 'Phone Information'
Scroll to the bottom and see what the 'Set Preferred network type:' is set to.
Mine works well with both GSM auto (PRL) and GSM/CDMA auto (PRL)
See if selecting one of these helps.
Let me know how this goes.
Hiya mate,
Yeah I gave that a try earlier. It seems I have to either have a good phone signal or crap data and vice versa? Pain in the ass. Orange told me that it was because of a faulty telephone mast in my area that has been off since last week. Can't see that being right to be honest, since my signal has been ****e since I first got it in April. Thing is, my sister was having the same problem with poor signal, and she wrote to some higher up person at orange to tell them about it. It ended up with her getting out her 2 year contract, bonus! I'm just going to ring and keep complaining and then write to this person my self, and hopefully I can get out of it my self. Orange is the worst network I have been on!
Cheers for your reply
I might give that a try. I still have a year left, but would love to jump ship and move back to Vodafone. I only went with Orange as my girlfriend was on Orange and magic numbers meant free calls. She then went and screwed things up by moving in! Now I don't need to ring her so much! (facepalm)
My housing estate has a dirty great big cell tower mast at the top of it. My fillings could receive a text message. But even with max strength signal still the 3G is off and on so erratically it's not worth using. They keep telling me that "the cell tower in my area is being worked on" too. That's been their excuse since February.
I have no idea I'm afraid why your phone wont stay on a WCDMA setting however. How are your APN settings? Mine once roamed to T-Mobile without me noticing and would only do 2G.
Yeah my girlfriend is my magic number too, and I live with her as well.. Doesn't make a great deal of sense really does it?
I think you may be on to something with that tmobile thing. Does tmobile allow wcdma?

When I used to do a manual scan for other Networks the following would show up;
Orange
Orange 3G
T-Mobile
T-Mobile 3G
If I try to connect to T-Mobile 3G it wont let me. The one that is just 'T-Mobile' doesn't have anything more than 2G. What happened was my Orange signal dropped out, so it jumped onto the 'T-Mobile' one without me noticing. It then didn't go back to the Orange 3G when I got home.
I just tried it again and got;
Orange
T-Mobile UK
The 2G/3G variants seem to have been dropped and merged into a single provider for each network. I can connect to T-Mobile but still only seem to get 2G.
See which one your connected to. It might be that although we are allowed to use T-Mobile for calls/texts the deal doesn't include 3G.

Yip, that's exactly it mate. I go on tmobile and I can get only 2g, I connect to orange and it let's me have 3G. It jumps between the two networks, and as I have poor orange signal all the time it auto jumps to tmobile! So basically it looks like I'm stuck to 2g if I want to actually speak to anyone! At least now I know what the problem is, but it still doesn't make me feel any better about having to make the choice, and having to constantly check which network I'm on before knowing why I'm getting either poor 2g or poor phone signal. What a headache!
Cheers for your help, much appreciated!
This sounds like some bulllllllllllllshiiiiiiiiit.
Orange and T Mobile have both always been ****.

Lately, I've noticed some **** with o2 as well which as I previously recall always had good service, since I been with them for as far as I can remember. I'll have full 2G signal, and randomly the data will shut off. Sometimes for a few minutes, sometimes for hours. But the phone signal remains on full... it's weird. And 3G coverage seems to be getting worse instead of better. None of this makes sense either since in March o2 apparently rolled out 900 Mhz 3G across most major UK cities, meaning 3G service on a 2G band, meaning much better 3G service in areas where only 2G service was previously good. I ain't seen **** all of an improvement, like I said it seems to be going the opposite way.
UK used to be ahead of the game when it came to cell networks, it seems most other countries have not only caught up, but jumped miles ahead. 4G is pretty standard in the US now, and they were so far behind in cell networks only a few years ago.

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.

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.

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.

BAFFLED: no LTE, tried everything

(well, everything short of new SIM card)
The situation:
-bought a 32GB N5 from a guy
-I'm on Rogers in Canada
-on Lollipop
-cannot get LTE, only 3G and 4G (H)
-APN is correct
-checked everything in *#*#4636#*#*
-cleared cache
-reflashed facotry image
-tried Cataclysm
SOMETIMES, I'll get "LTE", but it's a phantom - there actually isn't a connection at all.
I've swapped phones many times before; never had an issue. I read in threads someone saying that on AT&T that you need to register IMEI with them to get new device working with LTE. I never had to before, but called Rogers to check if this is something they've started doing.....no.
Under device model, it doesn't say either 820 or 821. It says "Nexus 5"
I started thinking that I stupidly bought the international model off the guy, but then when i was in fastboot mode I saw that it did say 820.
So.............I'm stumped, puzzled and pissed.
Does anyone, ANYONE have suggestions or ideas? Many thanks!
Sanity check but worth investigating:
- Definitely have LTE coverage in your area? I assume other phones around you connect to same LTE network no problem
- Does the SIM connect to LTE in another known working phone?

Yep, coming from my old phone. Have always had coverage in all the areas I've been with this new phone. LTE SIM, LTE area...it SHOULD work, but is not.
Try a new sim at the store, if it doesn't work return it on the spot. No harm, worth a try
Does 3g work? What bands does your carrier run in your area? You might try the diag LTE screen (requires root, there's an app from the Play Store) and see what band it sees. Also have you tried doing a scan of which carriers are available?

3G and 4G work.
I went to Rogers store and got a new SIM. No change.
Same thing...
I'm just posting to let you know I've had EXACTLY the same problem..
Mine occurred after I smashed the screen and sent it away to a company to be repaired. My N5 came back with a new screen, so immediately I upgraded to lollipop...
Then the LTE stopped working. Occasionally the device would say it was connected to 4G but, like you, it didn't work when it showed this. I tried everything, flashing, checking access points, flashing different radios...but nothing worked.
Now I can't work out if the repair company had somehow damaged the 4G antenna when they were fixing the screen. So I sent it back to be repaired (again)
Now i've got it back. 4G works but it has lost a lot of speed. Where I was getting 25mb/sec on average, I now get 10 max.
I've e-mailed the repair centre to find out what they did, but honestly, I've given up a bit now...
Wait, you upgraded to Lollipop? You realize that they included a new radio right? Try reverting modems.

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?

Its only LTE that I don't get, but it was only after I updated to CM12. I reverted back to kitkat right now and I no longer get LTE.

No you didn't, you said you used the *#*# setting which is NOT the same as APN setting in the Mobile Network settings. Before insulting people do your homework.
APN worked!

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:
