[Q] Problem with not receiving calls/texts while on LTE - Nexus 5 Q&A, Help & Troubleshooting

I started to notice that I wasn't receiving a bunch of calls or texts on my Nexus 5 for a while, and then I was able to figure out that when I'm connected to LTE, my phone won't receive any calls, it just goes straight to voicemail and I never get a notification of a missed call on my phone. Also texts will be delayed until I'm not on LTE. When I turn LTE off and 3G on only, it works just fine. I'm with T-Mobile, but Sprint users have reported the problem as well. Does anybody else have that issue or have you heard of that issue? Is there any type of fix?
There's a link to google's productforums where a bunch of people are having the same problem when connected to LTE. but I can't post the link because I don't have 10 posts yet, lol. The title is Nexus 5 sometimes doesn't ring when people are calling it.
I'm wondering if it's not a more widespread issue but most people just don't realize they aren't missing any calls because they don't have any missed call icons or anything.

This usually occurs when you are on LTE only so I am guessing the issue is that its not switching to HSPA properly. I assume your device when its not on 3g only is set to use all networks. Hopefully this gets resolved for you.

if your phone is on lte only, you can not recieve phone calls or texts, it needs to be set on lte/gsm as phonecalls go gsm and not lte.

htc touch troubleshooting -- call issues EVDO to 1x coverage

can anyone help me with my htc touch issue? not sure where else to ask this
i recently started having issues with reception after having NO problems with the touch since it came out. i come home for the day and my phone shows the evdo icon, but people try to call me and my phone doesnt ring, but the caller goes straight to voicemail. then it goes to 1x and my calls/email sync are fine. in order to try and get around this i perform a soft reset. however, when the phone comes back up it goes back to evdo and tries to dial #777 and fails numerous times. i try to make phone calls for the first couple of minutes that the phone is on, and they immediately terminate before im able to connect. the phone then goes into 1x and i can get data and make phone calls.
it isnt necessarily a problem with evdo connectivity itself, as when im at work i can get phone calls and data with evdo.
i did a hard reset and the only thing i've installed is a touchpal keyboard, but the problem is still occurring.
i called sprint and did a prl update from my house, and the tech support person said im in an area where coverage shouldnt be an issue. even with the prl update, im still having a problem.
this is very frustrating because i am missing important calls from business contacts.

S5 wont Ring on incoming calls?

I can do everything else on it. Text, Place calls, receive text and emails, surf the web. It won't ring calls are going to voicemail. I got a replacement phone from best buy. I have spent 2+ hours with sprint CS resetting and upgrading everything. I'm coming from a S4 that has been wiped.
Has anyone else had this issue? Fix?
Thanks
Phone is completely stock.
Have tried:
Battery Pull
Update Profile, PRL, System update
Did the ##72786# "refresh"
HELP!
Had the same issue where my phone wasn't ringing on calls received. The ##72786# refresh fixed it for me. Has not happened again.
Yeah, i thought maybe I was imagining it but i had like 2 calls go to voicemail from a roadside assistance company i was waiting for call from last night. Thought it was odd but now you say your experiencing it too.

It resets the provisioning on the phone and forces it to re-download the activation settings. Aka kinda like a re-provision.
I'm having the same problem, but only when connected to LTE. Have you tried turning off LTE and seeing if you can get calls? Maybe we have the same issue with our phones/area.
same issue
It's been a while so I assume you resolved the issue.
I have the same issue. Switch to CDMA fixes the issue but then I have no LTE. tried the phone reprovision code. It worked but then stopped working after 1 call.
Same stupid issue
I have this issue and would really appreciate it if someone could share the secret to getting incoming calls.
Issue is with the service provider. In my case Sprint. Turning off Wi-Fi calling and Wi-Fi helps but CDMA only mode for places where there's only 1 to 2 bars for LTE Spark is the solution for now. Call up your provider and let them know about your issue.

Text Message and Wifi calling On

I have the T-Mobile Variant and was wondering if anyone else had this problem. I turn on the Wifi calling since my signal is low where I live at. But when I try to send out a Text message, I keep getting an error immediately that it fails to send. So I turned off wifi calling and then the text message goes thru. Weird but was wondering if there is a fix for this? I spoke to a T-Mobile rep and she couldn't figure out the problem either. I do like the Wifi calling feature but if I need to send a text message I have to turn off the wifi calling every time. Any ideas? Thanks in advance!
Based on my research, it comes with the territory. I wish there was a hands off workaround.
I've had the same issue with multiple Samsung phones (Sidekick 4g, s4 and s5), I think it's just one of those little pain in the *ahem* quirks. Super annoying
What's super annoying is it works as it should (text messages through WiFi on sprint) so it has to be something T-mobile did in their implementation.

Anyone else missing calls?

I'm having a bit of a strange issue. Not sure if it's related to charging or not, but I have missed at least 3 calls with no notifications only to get a voicemail notification. I believe the first two happened on the charger and the third just happened a little while ago definitely on the charger. Most calls seem to come through and my apartment can be a bit of a reception nightmare; however, my signal is always 3G at home to negate that and this wasn't an issue on my old phone. It seems that my device randomly drops onto a 2G not my network occasionally(Bell/Telus don't have 2G gsm towers, only Rogers). Roaming is disabled which would explain why I would miss the call entirely, but every time I check my phone, it's registered on the network it should be with 3-5 bars of signal
I get a lot of phone calls from work so it can be a bit frustrating... Thankfully they always leave a message. Anyone else missing calls?
Are you using a wireless charger? I've heard claims that wireless charging can interfere with signal. I can't confirm it for myself as I very rarely get phone calls, but I certainly haven't received any calls while wireless charging. I don't have voicemail either, so I could be in the same situation and not know it. :silly:
Yes. I am having the same issues of calls not coming through, but only being notified if a voicemail has been left. Though my issue does not just happen when my phone is being charged. I went into USCC and the associate could not replicate it as it occurs randomly. She called tech support and they could not come up with an answer. The associate when on to say it was the callers phones causing the problem and not mine. Yeah, right.
missed calls
I have a galaxy s6 active on AT&T and I'm experiencing the same issues. It has happened while my phone is not on or near any chargers. It also had full reception as I was in the same room as my AT&T microcell. My wife asked if I heard my phone ring, but it didn't when she called. She tried calling it while I was next to her. Her phone dialed and rang, but my phone had no incoming call. I also tried calling her right back, but it would not dial at all. I just purchased the phone and will quickly be taking it back to exchange for something else if I continue missing calls . Has anyone gotten feedback?
It happens to me. Usually when I'm in a building with a metal roof., but not always. It's random.

Me too
Just upgraded my S3 to S6 and I've been nothing but issues with missed calls. I'm usungOtter box case on my phone. My phone could be right next to me in the house or be in the charger and I'd miss the call. It never happened to me...ever in my house.
I haven't called Samsung yet for support. Not sure what they're going to say.
I had the same issue but it is rare. Updated my firmware helps with the signal.
Got a lot of missed calls on XtreStoLite 2.2 (see details at bottom) and sometimes answering calls not working too.
Was on a fresh original firmware before flashing rom.
I just updated to 2.4. Hope is related to Baseband Version. Will report later if still got same issue.

Same story with full LTE signal, wifi calling off. Incoming calls fail to reach my phone most of the time but outbound calls always work.
At my office a majority of my incoming calls do not come in... the people calling me report it "rings" 2 times and goes to my voice mail. The phone does not ring, show any notification a call is inbound, nor does it list the calls in the log.
Voicemail notification and SMS are the same story... I sometimes get a text message 30 minutes after it was sent by the person when the inbound cell stuff decides to start working.
Now if I make an outbound call, inbound calls and sms will arrive no problem for about 30minutes to an hour... but it eventually goes back to missing incoming messages.
I've gone through the agony of customer/tech support, switching on/off VoLTE, Wifi calling, call banning, Do not disturb, etc. but no luck. The phone seems to go into some suspend mode with the tower and nothing can get in .
95% of missed call issues are carrier based. You may want to talk to your carrier about putting in a network ticket or about getting a replacement sim.
That said, OP specifically, try putting your phone in safe mode when charging and see if it continues.
I forgot to mention this is a tmobile-branded device.
I was able to confirm that this is a baseband firmware issue (G920TUVU3D0I1) that incoming calls are missed and texts are substantially delayed after a certain amount of screen-off time. My original device and first replacement had this baseband version and had the same issue on two different sim cards.
The only solution is to get a device with the older baseband version (G920TUVU2COF8) which my second replacement had and has been working trouble-free ever since.
Patch coming to 5.1.1
Rogers just confirmed there is indeed a problem with the latest 5.1.1 causing the SMS and call issues and a fix is coming 11/16. We'll have to see when the other carriers push this out

Tmobile is rolling out G920TUVU3DOJ7 tonight, hope this is the same fix Rogers discussed on their forum
Before i start I'm not saying any of you are involved in any criminality but incase you are worried about your privacy/security in any way shape or form its worth considering what im saying, I'm sure you all know of ed Snowden revelations and you know that L.E. have the capabilities to remotely activate your phones mic. A friend of mine has been in this situation where when in a sensitive situation altough having full signal and in an open space and where not able to recieve any calls as the mic was already being used by some unknown entity. In these situations if my friend tries to make a call it doesn't go through the first try, it doesn't even go to answer service just cuts out. Next time he tries to ring out it goes straight away. Him making the first call cuts them off from listening through his mic. Things have then happened after some of these conversations that would have been impossible without the monitoring .
Again I'm sure none of you are involved in any dodgy dealings but it's worth knowing if your conscious of your privacy.

I can't make any normal call, but full network coverage, and internet 4G normal

Hi,
I have not been using my OP6 because of a strange issue with it since OOS 10.3.9 (maybe since May 2021)
This issue is: I can not make nor receive normal call with any provider. but my network bar is full and my 4G internet is running smoothly.
If I try to make a call, it just show the call screen, no calling tone and no waiting tone and the other phone doesn't ring.
If I try to call my OP6 from other phones, it just doesn't connect, no call tone no waiting tone... My OP6 also doesn't show any incoming call.
I'm sure my sim cards are OK, I have tried to put them in a different phone and they can make normal call.
If my sim card slots were broken, I would not have any coverage and my 4G wouldn't work...
I can receive SMS just fine.
anybody can help me?
thank you
I had the same issue, at the end oneplus said, bring it to a service center while there plenty or forum posts in their forums from technician saying it's the network chip, i got a new phone but will attempt to replace that chip once i got my replacement.
You could try other stuff, full wipe, other roms etc.
