Bionic w/CM 11, orange LTE signal bars

My wife's Bionic is on CM 11; however, it seems to have a hard time staying on LTE - it keeps showing orange signal bars, and when that happens internet is lost.
Is there something I can do to fix this? I heard something about replacing APNs, but not sure if this works for the Bionic, or exactly how to do it.

What carrier? Have you tried reactivating it?

Verizon... and of course it has been activated, she's used it for quite a while. I did try the *228 option 1 and 2, although I have heard that that doesn't work or do anything for LTE phones.
Note: On my Razr CM11 I actually have an APN option under settings... mobile networks; but that option doesn't seem to be on the Bionic.

Try a new sim card. They usually will give you a new one for free at your local official Verizon store.

Has anyone found a fix for this? I experienced this a lot on cm11 m10+ on mine and another bionic and was annoying till I switched ROMs

Connectivity issues on 3G/4G - anyone else?

It looks like there is an issue with 3G or LTE connectivity. About half of the time internet connection is extremely slow or there is none at all, even though there is 100% reception. It doesn't apply to a particular app but to the whole system. Again, only with 3g/4g, but not on wifi.
It's an international version Nexus 6, bought in the UK, factory unlocked. It's running stock 5.0.1, not even rooted (for now). I've tried reflashing stock and nothing.
Anybody has experienced something similar?

maybe its your local network service thats at fault? have you tried calling your provider? its not here, i just got 55mbps download speed in a speed test.

Thanks for that but no, that's not the issue.
I swapped sims with my previous phone, which worked perfectly fine. That same day I experienced the issue with the Nexus 6 so it's not really a network connectivity problem. I may try getting a new SIM card but I suspect that's not it - otherwise there wouldn't be connectivity at all.

if you are on android 5.0 still, then your speeds might be a little slower than before(mine was slightly slower, not extreme). i had the same when i was on stock 5.0. after 5.0.1(ota just started, factory img available to flash as well), you should see a little better data speeds. i did at least, after flashing the radio that came with 5.0.1. if its not about data speeds, then i dont know, sorry.

? Question about Verizon and data roaming

Using my N6 on Verizon, I frequently get messages that I have left my home and dont have data roaming enabled. I don't understand because my note 3 had no problem with Verizon. If I turn on data roaming for data might incur charges from some other provider? On the status bar it used to say either T-CDMA or Verizon Wireless, now it says 3100. My SIM is the same one I used in the note 3. If it matters I am using Liquid Smooth ROM and Franco r2 kernel. Voice seems to work. Any suggestions are welcome.

I'm having the same problem. I have to keep going back to stock to get LTE. I've tried liquid smooth, validus, and bliss pop and all gave me roaming and no LTE. All are their latest builds too. I've also tried popping in and out the sim card with reboots as well.

That is exactly what I am seeing. I'm on WiFi 99% of the time but when I leave the house I have no data.

Good ole Verizon making it impossible to do anything without them approving first. Its probably because Verizon doesn't want people to use the phone on their network before they release it.
They've never been good about nexus though. If you don't recall the whole galaxy nexus debacle

I had the galaxy nexus on Verizon but don't recall them interfering. I do hope that once they offer the 6 that our network access is unfettered, or the community will figure out how to make it work with custom ROMs.

Your roaming goes away? I can't run any ROM without roaming on Verizon...

I noticed this issue on CM based ROMs. Any that are stock based are not effected by this bug, for me at least. I have spent a couple of hours trying different things out that people suggest but none of them have worked. I was able to get 3G to work on liquid, but no LTE. and it reverted after a reboot. I sure hope someone can get this fixed soon.

im running cm12 on my n6 and using verizon and it works perfectly. No issues.

on Bliss Pop the Status Bar icon is NOT roaming but if you pull down and check the tiles it says roaming. I dont think its actually roaming though...LTE Discovery tells me I am still LTE and so does Network Signal Info.
So I think its just in the UI.

You think it is still on vzw when it thinks it is roaming. If I enable roaming data I won't get a huge bill from some provider?

Well, I cant swear to it for sure, but I from the apps I have I am still attached to the same cell tower, so not sure how that would equate to roaming.
LTE Discovery also shows as roaming, but all the other info also shows LTE. Same for Network Signal Info.
IANAL , but if your attached to your normal home cell towers, it would be hard for us to be roaming I would think....and hope

It may have to do with LTE vs 3G. When not on LTE it says 3100 (or 31000?) and that bus when I am "roaming". So confusing. I've gone back to stock rather than Liquid Smooth. I will try an AOSP ROM like Pure to see what happens. Although I'm not missing much on stock.

So all I can add is that I just looked at my bill which ended today. I have been using BP for the last several days at least, and I have 0 roaming charges FWIW YMMV all those caveats....I have a Nationwide Talk 450 Min plan with the standard 2gb data.
HTH, but remember I added the caveats, caveat emptor

Any update?
I have same kind of problem too. Im afraid the bill will goes up by this.
Please let us know if there is a fix for this

Yeah same problem... I don't get why some Verizon users agent having the same problem. Would unrooting and doing a factory reset maybe fix the problem? Frustrated that I can't run a custom ROM without roaming...

Go take a look at your bill/usage online and see if things are showing as roaming. like I said mine looked fine. And it seems like an issue with quite a few roms from understanding.

I just tried out Broken and it has working LTE on Verizon! I'll have to look at my bill, haven't been on a custom ROM with roaming in effect for very long though, so I probably wouldn't be able to tell very easily.

I have a Stock Rooted, Unencrypted N6, with a few custom Tweaks. On VZW have not had ANY issues whatsoever with my service or LTE. Perhaps some custom ROM/Kernels might be causing these issues?

Stock seems to not have the issue. It is said herein that AOSP based ROMs don't either but that is not true in my ecperience. LTE Discovery says 31000 is Verizon Wireless so I believe that even though it thinks it is, it isn't roaming from VZW. I enabled data roaming and switched back to Liquid Smooth and I should be alright. Thanks to everyone for the insights.

[HOW TO] Fix LTE Issue with CM 12.1 based ROMs and Sprint as your carrier

This may fix jfltespr on the Sprint network always worked fine with LTE on most ROMs, but not with very many ROMs lately.
It seems that the APN had one slight difference between ROMs that worked with LTE for me (older CM, stock TW, GPE), and ROMs that had no LTE or eventually dropped LTE (CM12.1 based). The bearer was not set to LTE in the APN profile for the ROMs that do not work for me. Changing that quickly fixed the problem (figuring it out took me much longer). I looked around a bunch when I had this issue, and found people with the same issue, but no solutions. So, that's why I post this here now. Here's the How To if needed:
Go to Settings, Mobile Networks, Access Point Names, and Sprint LTE internet.
Scroll down to Bearer and see what it is set to. Mine was Unspecified, and that's what was causing the issue. Set Bearer to LTE
Go back to APNs, and also set Bearer to LTE on Sprint EHRPD internet. I know that's not the normally selected APN, but if you only change Sprint LTE Internet, it seems to automatically change to this EHRPD one, and it still doesn't work.
That's it for now. Enjoy your LTE again on 5.1.1. It seems to be much smoother.

I'm on an LG G3 but this APN/LTE issue seems to be affecting a lot of people on Android 5.1.x. I've been searching for solutions for days. Unfortunately, I have to report that your method did not work for me. With the Bearers changed to LTE I'm not getting any connection at all, but with them Unspecified I'll get a connection for a small time (<1min) after switching preferred network from 3G back to LTE before it drops again and gives me the exclamation point. If I leave it on 3G I have no problems retaining a 3G data connection. Nexus owners appear to be having this issue en masse with their 5.1.0 & 5.1.1 updates from google so it doesn't appear to be a CM issue, though CM had some APN related commits on July 1 that also seemed to cause problems for people and were undone by devs of some CM-based roms.

Yea that's a bummer. Thanks for sharing though. Maybe having it happen to so many people means that it will get fixed sooner than later, but I can only hope. I can only speak for the Sprint version of the S4 running on the Sprint network. It seems that people with this exact phone are okay on other networks.
This fix wasn't 100% for me either. Every once in-a-while, I think mostly in particular locations, it'll get stuck on the exclamation mark, and I'll just have to throw it into airplane mode for a moment.
If you haven't tried yet, make sure to put the bearers to LTE for all APNs that have the same DNS name as the normal one that you use, and the others at their defaults. It's probably not the case, but your results sound similar to mine when I only set one of the APN bearers to LTE. I thought that might be worth a mention, but I'm sure there are deeper problems. Sounds like you probably already did that anyway...

I've been having problems with this too and I tried your method but it didn't help me. It's really frustrating when there's so many great roms that are useless but thanks for trying though. Hopefully it gets resolved soon.

AOSP automatically selects the correct APN as long as the bearer is unspecified. You can hard code the bearer, but then that APN is only valid for that bearer. In other words, setting the eHRPD bearer to LTE will make that APN only valid for situations where the radio is connected to LTE. However, the connection will fail because the APN settings are wrong and the system will automatically move to the next APN with the bearer set to LTE. This time the connection will succeed because the next APN is the LTE APN. If you set the eHRPD bearer to LTE then you will never get a 3g connection.
What exactly are the symptoms you guys are seeing with LTE? My wife and I are both running CM with no connection problems whatsoever.

For me, I just randomly lose data connection, both 3G and LTE. It will then reconnect a few minutes later. I tried removing the other APN like the freedompop & ting leaving only sprint APNs thinking that might help but it I still lose data.

Do you get an explanation point?
Take a modem log right after you lose data and send it to me in a PM.

MMS ???
Hi. I am running CM12.1 and have tried other Lollipop roms. I am using Ting as my provider. I have two issues.
1. I don't get voicemail notifications. I can live with that.
2. Picture messages don't show. Texts come and go with no problem, just not picture (mms) texts.
Would these fixes help my issue? I have had no issues with 3g, which is most of my coverage area. I am usually on wifi anyway.
Thank you!

Cm12.1 ignores the voicemail notification from the carrier. The MMS issue is an incorrect/missing APN. If you can figure out what it should be we can get a patch submitted.

Here is a jfltespr build that fixes Ting data/MMS. I strongly recommend a clean install. If that's not possible, be sure to reset APNs to defaults after you flash and then reboot. It will take a minute or two to get data after the reboot. Please let me know how it goes. If this does fix it, I will submit the patch. If not, I still have some ideas.
Be sure to make a nandroid backup as I couldn't get my wife's S4 to test it with and this was the first time I have built for the S4 on this machine.

This build is up to date with CM sources as of last night.

I am downloading now and will try it tonight. I appreciate the quick work. I am on Octo now, but really prefer CM. I will clean install. Thank you!

I loaded it on and everything works except for mms. My 3g is good, wifi, texts, internet, calls ... just no pictures in texts. Something I noticed was different from the other CM12 versions is that now I can see that the text was sent, I just can't download it. I tried these settings from this page - I used the EHRPD settings. They were able to make mms work using the Octo rom.

What fixed your problem? Setting the 3g bearer to LTE? That means the freedompop LTE APN is wrong and should be patched in the code. If we could get more input on this we could fix it for good.

Tap airplane mode, then tap again to turn airplane mode off. Then go into your APN menu. Your APN's should appear.
I'm running the latest CM 12.1 nightly. The stock APN's work for me, but I rarely get a LTE connection with them.
I've flashed the APN fix that's floating around, and it worked in older builds of CM 12, but recently the fix just disconnects and leaves me with no signal.
If I do what OP suggests, I'll get an LTE connection, but that leaves me with no 3G where LTE isn't strong.
I guess the problem with CM is that it cannot successfully switch between LTE and 3G correctly.
If you're not all that concerned about getting an LTE connection, I'd recommend just sticking with the stock APN's. Once you start flashing fixes, you're gonna have a problem.

Cell signal keeps reverting to 3G

Hi,
So I'm having an issue keeping an LTE signal. I use straight talk with at&t and I can get LTE if I turn the radio on/off, but it will always switch itself over to 3G at some point in the same location. There are apps that can force it to do LTE only which works, but I can't make or receive voice calls over LTE.
Does anyone know how to fix this? This never happened on other phones on the same network. In my specific location I get 2-3 bars of LTE and 4 bars if switched to 3G. I guess it wants to keep using the better signal.

Also at home where I have full signal LTE and H+, it will choose H+ over LTE.

Had same problem. Switched sim slot to the other. 4g again. Try IT?

Did you try different APN settings? I'm guessing you already checked the preferred network option.

APN settings are good and I can get LTE if I flip the radio on and off...it just always wants to revert back to 3G at some point. Same thing happens in sim card slot 1 or 2

Which rom are you on? I remember there's a specific rom that has a bad modem file. Trying updating to the latest version.

Maybe you can solve it by going to APN settings and set APN protocol -> IPv4 and APN roaming protocol -> IPv4 . That worked for me. I had the same issue.
Or try IPv4/IPv6. That's network related and maybe IPv4/IPv6 is correct for you.
I have to set it every time I flash EU or EPIC rom.
Good luck.

did you ever figure this out?
I'm having a similar problem on a Note 4 Global. Only it switches to 3G for a voice call and never switches back.

I've updated it, and it's all the same. Once in a great while it will switch over to LTE on its own, but 99% of the time it will just sit on H+ forever even though I know the LTE is fine wherever I go.
I guess this is just how it's going to be.

I finally fixed this by wiping everything in twrp and flashing a newer version of the global stable rom. LTE works fine now, and it doesn't stick on H+ when I make a call anymore.

That's interesting. I guess Xiaomi fixed the bug in one of the releases. I wonder why you had to wipe everything though. What if we try to flash the latest modem. Is there a link to that? Would that work?

Would modem be the same as firmware? There's a thread on here that has those. None of them did anything for me.
My LTE problem is isn't fixed after all I guess. Once it loses LTE, it still never reconnects to it on its own and goes to H/H+ forever.
I guess the only thing that I've fixed is that it actually switches back to LTE after a phone call.
