[Nexus 6 Q&A, Help & Troubleshooting] seeansea:
I switched from AT&T to T-Mobile in early April. I have had issues with texts failing to send since I received my Nexus 6. Two weeks ago, fed up with the text issues, I flashed the factory images for 5.1 and when that didn't fix the issue I flashed the 5.0 image and let the T-Mobile OTA to 5.1 occur. Again, did not fix the issue. I then had them replace my SIM card, again no fix.

Then, soon after the new connectivity service app was released I also started to enjoy frequent periods of no signal at all, or the ! signal and no connectivity.

I experienced this in the Seattle area, and also now during my travels in Hungary and Croatia. My wife, with her iPhone 6 has not experienced a single issue while I am frequently fiddling with my phone to establish connectivity.

After having a slew of issues with my Nexus 4 perviously, and no issues with my own iPhone 6 just prior to obtaining the Nexus 6, I have to say I have really begun to doubt my faith in Android and the Nexus program. I sincerely hope this will be fixed soon and I'll watch this thread very closely in the immediate future.

FWIW: carrier is AT&T. While I've lost my signal and had to reboot, it's very infrequent, and it's always been in a very weak LTE signal area.

LMY47I with 95R radio.
[Nexus 6 Q&A, Help & Troubleshooting] psak:
i've experienced similar behavior & noticed that at least in my situation(started with an introduction of either 5.0.2 or 5.1), phone didn't stick to a proper APN. once the phone call is made or the phone comes off a WiFi or jumps from LTE tower to lower grade 3G tower(phone forced to switch modes due to losing a signal with a tower for a moment). that is when I notice that the phone wasn't assigning itself to the APN that was chosen previously.

t-mobile example: phone chooses/drops back to top of the list APN, even if I was on 3rd or 4th APN that I have in my phone . after clearing or rearranging my APNs, so that LTE fast.t-mo APN is top entrance, I no longer experience connectivity problems. currently running benzo 5.1.1 LMY47V with .95R radio, VoLTE checked on.

[Nexus 6 Q&A, Help & Troubleshooting] v8dreaming:
I'm on T-Mobile. This happens to me when I'm using Wi-Fi. After a while of the phone sitting idle, I lose connection to Wi-Fi and cell data. If I turn off Wi-Fi, cell data will come back. It doesn't matter what ROM I'm on, and it's been happening since I got the phone in January.

Same problem with Sprint as well. Anyone else having issues trying to do the device config or Updated PRL? I have to call Sprint for it too work.
[Nexus 6 Q&A, Help & Troubleshooting] meh3884:
These are not solutions to this problem. This issue is a specific problem that started around May 4th. It's not an APN or SIM card issue, root issue, build specific problem, it isn't solved by any of the standard solutions to the many previous Nexus 6 intermittent signal problems that have been occuring since the phone's release.
[Nexus 6 Q&A, Help & Troubleshooting] WhatAmI:
It's not just the USA (as for most of you) or anything to do with a certain carrier.

I'm in UK and just like everybody else my N6 started giving "!" on the cell and wifi icons.

This is 5.1 - not the later 5.1.1

There are other people in the house connecting ok to exactly the same carrier/cell tower and wifi with no problems.

So the problem is on the device - and given that's it all just started for everbody it means it must be a software issue.

I found switching off the Wifi and then switching it back on again cleared the error - until it happens again. No need for a switch off restart.

I tried disabling various options to do with wifi/cell switching and stopping location options etc etc but nothing seemed to stop the problem. So it's something deeper going on with a recent Google App update.
[Nexus 6 Q&A, Help & Troubleshooting] gooface:
This has been happening to me all the time as of lately, I am on T mobile and still on 5.0.1

I will be using my phone and the data stops working and then I shut the data off then back on and the "!" symbol appears. I will then proceed to restart the phone and when it comes back on its working again.
[Nexus 6 Q&A, Help & Troubleshooting] frapfreak:
This is happening to me, too. Tmo, OTA 5.1 update.
[Nexus 6 Q&A, Help & Troubleshooting] noutoo:
I've had this going on for almost 2 weeks. I blamed Verizon. Seems to happen when I have a weak cell signal more. flipping to airplane mode fixed it most times but a few times that caused my phone to reboot. N6 from motorola running 5.0.1 Pure Rom.
[Nexus 6 Q&A, Help & Troubleshooting] rbox:
So I tried with the 5.0 radio and within a few minutes of getting to work my connection had dropped. Right now I'm trying with forcing it to 2G only. So far it's been like an hour and it's good. That's an awful solution, but it's an interesting data point. I tried it last week but didn't keep it for long because of how slow it was. I have a rock solid EDGE connection though, so if it works in this situation, I think it might prove somewhat it's related to signal strength.
[Nexus 6 Q&A, Help & Troubleshooting] rbox:
So it's been a few hours and I haven't dropped yet. I think setting it to 2G only might be a workaround for the people who are losing the ability to make and receive calls if it's important for them. Obviously the data is dirt slow, but I think a few people were having issues at home, and people at home would probably be on wifi anyway.
[Nexus 6 Q&A, Help & Troubleshooting] jbdan:
This works for me because I have done it previously with another device. I'm just so stubborn to have to make that compromise with my expensive electronic toy :sly:

[Nexus 6 Q&A, Help & Troubleshooting] midwestkel:
I'm glad it's been at least acknowledged. Hopefully it gets fixed quickly as well. Is it just me or has Lollipop had a lot of issues vs other versions? On 5.0.1, Chrome and other Google products would just crash on me all the time. On 5.1, my house didn't work as a trusted place so I would have to put my pattern in every time I went to unlock and now this. I didn't even hear anything from Google on the trusted places thing, it just started working again a couple of weeks later.
[Nexus 6 Q&A, Help & Troubleshooting] seeansea:
I don't know if this will work for you, but I had this same issue and my fix was to set Home as a trusted place AND manually drop a pin just a hair off of the home location. Having those two made the trusted place work flawlessly for me.
[Nexus 6 Q&A, Help & Troubleshooting] midwestkel:
Thanks for that. I haven't had the issue since it started working again but if it happens again I'll give that a shot.
[Nexus 6 Q&A, Help & Troubleshooting] Unclean009:
Have you guys tried uninstalling the update to Google Connectivity Services?
[Nexus 6 Q&A, Help & Troubleshooting] meh3884:
I am glad Paul responded, but we all know that's not just inconvenient, that is no solution at all. We can't watch our phones 24/7 to see when it loses connection again to restart again. In the meantime, we're continuing to miss phone calls and messages.

In any case, as an update from me in Seattle today, I was home yesterday and noticed that the issue seems *reduced*, as in, I'm not seeing the "!" so much, but it still shows up randomly from 3G/H+ signal and I still need to reboot to briefly fix. But I've noticed I am able to maintain an LTE signal much more than I was the days before. Hopefully this means they're doing something.

On the flip side, I had one instance yesterday where I had a working H+ signal. I was connected to the internet as though everything was fine, receiving emails, etc. However, I went to send an SMS message and found that SMS/Voice service was not working. I tried to make a call, sure enough didn't work. I needed to restart again, and then got a missed called and two SMS messages I had missed, so it must have been out for a couple hours. I don't know if this was a coincidental blip or, more hopefully, shows someone somewhere is working on the issue.

I'm also going to share this reply in the product issue thread.
[Nexus 6 Q&A, Help & Troubleshooting] WhatAmI:
Just to add some strangeness to this (in UK).

Normally I see "4G" overlayed on the cell/mobile icon.

During these problems it changed to "LTE" .

I know they are similar/same - but a strange coincidence.

Also, now it's showing 4G again and the connection is stable with no "!" appearing.

All very odd.....
[Nexus 6 Q&A, Help & Troubleshooting] JohnCorleone:
That's how I have had to use my HTC One M7 since late January on T-Mobile... toggle to 2G to make and receive calls and toggle back to LTE for data. Fortunately for me the custom ROM I use has a 2G toggle but it gets more annoying over time. It seems widespread and now I am second guessing getting this device on Thursday. I was told that it was addressed on Twitter by the askdez guy or whatever his Twitter name is...he is a T-Mobile employee or tech guy

---------- Post added at 10:22 PM ---------- Previous post was at 10:15 PM ----------

I have had the same happen twice in the past 2 days. It cycled to "H+" and "3G" which I hadn't seen for months. It briefly worked and then I was back to spending most of my time toggled on to 2G to ensure that I am not missing calls and texts...well actually texts are fine on LTE. It's only a making/receiving calls issue for me. I was told that T-Mobile is experiencing technical difficulties with WiFi calling but I don't see how that could be causing a problem on the Nexus 6 which hasn't gotten the WiFi calling update yet...only more frustrating. A direct answer would be nice before I lock in to another 2 year contract

I sent my message. Hopefully they can find answers. Today I went to T-mobile and paid off my Nexus 6 EIP in anticipation of needing to sell the sealed warranty replacement arriving tomorrow so I can get a different phone. I got a new micro SIM to test my somewhat broken Nexus 5. I will report back on whether the Nexus 5 gets the same problem here in my house. So far, I am still getting the 3G signal on it that I've been getting on the Nexus 6 before failure. Prior to May 4th, I used to get a consistent LTE signal here.
[Nexus 6 Q&A, Help & Troubleshooting] inick73376:
I also sent mine, I don't have the problem often just here and there. When I go and check my phone I see no signal when my Tablet does with LTE.

Screen shots of my phone when it happens. I'm unable to receive calls, or texts, and data doesn't work. Edit: Just realized I put my phone number on here. Haha Had to delete that one.
[Nexus 6 Q&A, Help & Troubleshooting] meh3884:
So far so good on the Nexus 5, I think. I did disconnect for a few minutes earlier, but not the "!" issue, just a loss of data connection. Toggling airplane mode brought it back and it's been fine since, about three hours now. 48 applications updated. I stopped by T-mobile to pick up another SIM for the 6 so I can switch back when I'm done testing the 5. The lady at the counter looked overwhelmed by what I was telling her, went straight over her head. Kept saying she didn't understand what I meant by "SIM status" and signal status. They also said they have had no one else come in an complain and wouldn't bother to pull up my T-mobile support thread or look at this thread. They *did* send an email to the T-mobile engineering team, but I didn't get any input so gosh knows what they wrote.

In any case, after doing research on the phones selling on eBay, I plan on going back tomorrow with my sealed N6 warranty replacement and playing hardball to get my $770 ($699 + tax) back or exchanged for an equal value phone. She was trying to tell me she'd only be able to give me trade in credit for the brand new, sealed replacement phone. I don't plan on losing over $100 selling the phone myself, T-mobile owes me a phone model that works. I'm certainly not doing this hokey pokey through 3 warranty replacement phones, which they say they require before considering trading for a different device. I think I am giving up my battle to love this phone.

Sorry for the rant. Wish me luck.

Over the weekend I tried disabling Google Connectivity and flashed back to 5.0.1 for which that app isn't compatible. It didn't solve this problem for me or IIRC a couple other folks here. Who knows how many issues there are with this phone - seems like more than a couple.

Amazing how few of them know even basics about cellular technology. I've been to T-mobile 4 times about this problem, talked to 6 or 7 different reps and only one guy had any knowledge or interest in the problem.
[Nexus 6 Q&A, Help & Troubleshooting] JohnCorleone:
I'll tell you what guys, I will have some answers on Thursday. I am getting my device from the T-Mobile store in Newport Beach, CA and one of the guys working there said that all of the management at that location are using the Nexus 6 and love it. If they are having the issue, they will want answers and be able to get them if T-Mobile is quietly having problems. I heard that they were phasing out 3G in place of a "3G+" so HSDPA could be getting overloaded.

As per the screenshots posted above, that is EXACTLY how my old Sprint device looks running on WiFi only except I even get the "!" to disappear without doing anything and this old device isn't even connected anymore. I just wanted to run CM12 on a device and its as smooth as can be on this phone...not so much for the T-Mobile One M7 that reached EOL...that ultrapixel camera has been all headaches for devs which is why I want to come back to a Nexus.

Edit...unless MarkAtMoto gets some answers first.

[Nexus 6 Q&A, Help & Troubleshooting] JohnCorleone:
This is so true. Many of the in store employees are only doing partial activations on some devices. Then when you call in many have to finish activating the device because no info shows in their system. If having a problem when you call tech support and bring up a full diagnostics check and manual reprogramming a device through dialer codes and the IMEI, many techs aren't even familiar with the procedure and tell you to "try getting a new SIM card from the local store." If your device isn't from T-Mobile, good luck getting any help. You had better know your stuff and hope you can fix it by going all the way back to stock and know a little bit more than how to root. Most manufacturers are making carrier specific devices with only select radio bands etc. That's why many people are coming back to the Nexus.

I really should say that it depends on the store and the rep who you happen to get though. A few times I got a tech who knew everything. If you are lucky, you get an in store employee who actually roots because then they know 10x more than the others

Nexus 5 is working so well I kept it today at work. No "!" so far. I reverted it back to KitKat, restored my apps + rooted and am not even having the crash/bootloop problems I *thought* were due to the notorious powerbutton/mobo problems, lol. At least not yet. This was/is a great phone.

Tonight I go to do battle with T-mobile over my warranty replacement. I hope we hear something by then. An admission from someone that this is a problem would go a long way for me convincing them that it's not my device that is a dud and let me just return the phone.
