Hey all, this all started a few days ago, I had gotten into the Android beta so I could get Nougat. It was running fine for a few days, maybe a week. Then after I rebooted the phone for something, it wasn't finding my cell network. I decided now was as good a time as any to root it and see what ROMs were out there, it had been a few years and I had never rooted my Nexus 6.
I installed Pure Nexus and it was all good for a day or so, then my phone kept telling me it wasn't rooted. Not sure how that happens, but whatever, I decided to go through the steps again and root it and make sure it was all good. Ever since then it has unable to find my cell network. It sticks on the initial search for the network when I boot up my phone. I'm on T-Mobile with a Nexus 6.
In Cellular network settings it can't seem to decide if it's supposed to use GSM or CDMA, keep jumping back and forth. As such "Access Point Names" disappears then reappears. Either way, it's blank. I've even manually added an APN according to T-Mobile's website, but it disappeared once it switched back to CDMA and back.
I've taken the SIM card out, put it back in, no luck. I've wiped, I've rolled back to my nandroid backup, I even used Nexus Root Toolkit to flash stock and unroot, still not finding my cell service. Any suggestions/thoughts?

If you have access to another SIM card I would try that. If you acquire a signal with another SIM card the one you have is bad. You could even try removing and reinstalling your current SIM card to see if that helps.
Flash factory images with out a sim and do a complete boot. I had issues coming to T-Mobile from Sprint on my n6. After first boot power down and insert sim, then boot. It should auto detect the APN settings.

If that still doesn't work, you could try flashing a different radio image from here: http://forum.xda-developers.com/nexus-6/development/fxz-nexus-6-recovery-flashable-fastboot-t3066052

Thanks everyone. I tried all of the suggestions, the first flashing without a sim, didn't work. I just wrapped up trying a new radio image, no luck there either.
Thinking it's probably just hardware, so bummed. Any other thoughts?
Thanks for checking in 31ken31.
Have ya tried and other known working sim cards on att or something to see if it finds that
Sent from my Nexus 6 using XDA Free mobile app
Just updating this in the event someone is routed to it through Google in the future. After flashing, trying to new sims, etc. it was pretty much guaranteed to be a hardware issue. The sim card reader is just not reading the sim cards. I upgraded to an LG V20 and am in love! Thanks for everyone who tried to help.

Been having this issue since before I even left the store with my new One.
Something like this would pop in the notification bar:

Also, I'd occasionally get a notification that the network didn't respond in time, the SIM card has locked and that I need to power cycle. Voice and data always worked. But either of those two would pop up at least once an hour. Yesterday, I pulled the SIM and and put it back in. That notification doesn't appear anymore, but I keep getting a notification that "the process com.android.phone has stopped", about every five minutes. My data connection will then tank for a few seconds and come back.
What could be the problem? I have no experience with SIM cards. Do I get a new SIM card?
Been getting random sim card errors as well.

I took the Sim card out and out it back in. Read somewhere that they come loose every now and then.
Sent from my HTCONE using xda premium
Taking the SIM card out and in at first stopped the invalid sim messages, but lead to the com.android.phone error like once every two minutes. Which sucked. Eventually it went away on its own though. But it came back a couple days ago, and happened like once every 30 seconds. It made the phone unusable. It got better by itself after about a day, the error is much less frequent now. PRL/Profile update did nothing.
I factory reseted, but both errors are still present.
What could possibly be causing this? Do I have a defective device? Sprint was clueless on the phone. It was doing this before I even left the store, but I wrote it off as nothing. Could I have a defective device?
Nahh i wouldnt even go to sprint. May have a talk with htc as they know a lot more than sprint.
Sent from my HTCONE using xda premium
Got the same error but not on Sprint. It probably an error on 4g signal. My solution is to switch back to GSM Mode only, or WCDMA Only (either of the two), then restart your phone. It might be an fault on a 4g tower.

Have Sprint check to see if the UICC on your account matches the one in your phone. This happened to me when I got my One and it didn't come with a SIM, so I took an active UICC from another One and mine did the same thing.
It could also be an issue with the card, or possibly the phone. Sprint has a pretty crappy system in place for this whole SIM card thing anyways.

very useful information, thanks, you save me the trip to Sprint!!!
Thank you so much for this advice. I had just taken my phone to the Sprint Store today after having my phone replaced and they couldn't figure it out. 10 minutes on XDA and I get the correct answer and resolved the problem by calling support. I should have checked here first!
I've been using CyanogenMod 10 on my Galaxy S i9000 for quite some time, and accepting the offered updates as they come in notifications. I used to use the experimentals and nightlies, but since the stable releases, I have only accepted them. But since the last two updates over the past two weeks, my phone now has the problem with being unable to save APNs and giving a message of No SIM Card. I understand these are related issues and was suggested to try APN Manager Pro to insert the APN data, but it won't even run, so I took the refund. SIM cards are ruled out as it gives the same message with 3 different SIMs that work in other phones.
I was advised to check for a good contact with the SIM card, and that checks out. CM advised checking to see if my radio file needed updating. When I first converted to CM, it took me a really long time to find a baseband that would work with this phone. So I have remained on this TUBJP9 for the couple of years that I have been running this phone on CM. GetRIL said I have RIL XXJVT, which I understand is the stock RIL for CM10.1. It suggested I match the modem, so I just now installed the XXJVT modem to match the RIL.
Since the phone won't work with 3 different SIM cards that work in other phones, it has been suggested that I simply have a hardware failure. Any suggestions would be appreciated.
Thanks.

Inserting Sim card in the wrong direction and Sim card holder getting damaged (contact pins twisted or broken) are quite common in Mobile phones, you need to eliminate them first.
since this happen on updates of a sudden (as you indicate) , its unlikely sim card changed direction or sim contact broke. I hope so, but no harm checking
so the easiest way to eliminate the problem is to downgrade it to Gingerbread Stock ROM and check if this problem is still there, if it is than likely you have a hardware problem . you can try this or switch it with JVT gingerbread ROM with re-partitioning
or if you had an earlier gingerbread nandroid backup, try restore.

I got your problem too..i've flashed few times my stock rom. Try to remove the sim before using odin and add it later.
Sent from my GT-I9000 using xda app-developers app
I was reluctant to go back to stock, but thought I had better in order to eliminate variables. Unfortunately this resulted in an Odin flash failure even though I included the pit file to account for the differences in partition layouts. So I was forced to go back to CM and accept that I have a Jelly Bean media player, or wifi phone at best. Having set it aside for a while, I was cleaning house and found an old out of service SIM. When I tried that, I no longer got the No SIM Card error. This was really irritating because my good T-mobile SIM also did not work in this phone, and when I took it in to the customer care center, they wouldn't listen to me about the possibility that a marginal SIM will work in some phones and not in others She simply took my SIM and said, look, it works in my phone and sent me out the door. Also I thought I had tested 3 good SIMs in this phone, but one of the SIMs I thought was good actually doesn't work in my other phone either. Still, out of 3 SIMs that work in other phones, only the one I just recently found works. I've heard of this kind of problem before. I just wish the customer care center would have humored me and let me try a replacement SIM. Then I wouldn't be out the $175 I spent for a replacement phone.
Hi everyone,
I gave my mom a Moto G 2014 for christmas and updated it to Lollipop a few weeks ago when the update was pushed OTA.
However, ever since updating, an exclamation mark appears next to the Mobile Network iccon and I can't connect to the internet on mobile data now, even though it worked fine before the update (no exclamation mark then). WIFI works fine though.
I really need a solution as right now we are paying monthly for data we can't use. I already tried the following:
Switching to the second sim slot;
Deleting and restoring APN's;
Rebooting the phone;
Clearing cache through the recovery menu.
Unfortunately, nothing worked. I don't want to factory reset if possible, as this is my mothers first smartphone and nothing is currently backed up. She really enjoys the phone as is, and I don't want to mess with it.
If you know the solution, please help out.
Thanks!

You said deleting and restoring APN's. Have manually edited the APN to the correct values?
No, I used the restore to default option. I contacted Motorola support and they sent me instructions per mail on how to delete and restore my APN's, so I followed that to the letter to no avail, unfortunately.

I experience some problems with my automatic network selection.
My carrier uses its own GSM cells for connectivity where they are available. But they also have a contract with a different carrier to use they're cells when a proprietary one is not available. This means that if the phone does not detect a cell for my carrier it will connect to a cell from the other carrier. But this will switch the phone to roaming, meaning different data plan and stuff.
The problem is that it seems the phone can not make a priority for my carrier cells and it often switches to roaming. This might be either because poor phone optimization, GSM signal or simply no cell available. But with my old phone this was not an issue and it rarely switched to roaming.
This might be connected to your problem and I hope for a sollution for this.

Ok, this is frustrating. I can't seem to get VoLTE working. Clean flashed, and in the hidden menu there's this View attachment 3217747. I didn't ever set it to ON, so I don't know why the OFF option is there. Whenever I make a call, the LTE icon goes away, and no internet.
Not sure if this will help as I don't know what steps you have already taken, but have you gone through these steps first?

No, no app. Maybe you should try enabling on stock and then flashing back to Euphoria. Maybe that will help.

Sent from my Nexus 6 using XDA Free mobile app
Before I would get the setting and it would be enabled but I coudn't do simultaneous voice/data. I flashed stock but now i get server error try again later each time. weird.
I'm completely stock verizon nexus 6 (recevied mine yesterday in the mail), but I was having same frustration you describe. Could not use hotspot and browse internet while in a voice call. And it was always in 3g.
I don't know if this will help but here is what I did.
first I did the hidden menu... *#*#4636#*#*
tapped the volte provision option and then I forced a power down.
After powering up I confirmed that the Enhanced 4G LTE was enabled in settings.
I went back into the hidden menu and confirmed that volte provision was turned on. It was because it now showed the "Turn OFF volte" option instead of "Turn On".
I retried using internet/data while in a voice call and the phone still would not allow data while in the call. I could only get 3g in hotspot and voice calls would still interrupt data.
I then learned that I had to enable HD or whatever the new service is called on my Verizon account. They said in the webpage instructions that I may have to reboot and check for system updates. And to wait about 15 minutes for it to take affect.
I rebooted, forced a check for new system updates (there were none), and then I tried retesting by turning on hotspot (still was just 3g) and trying to place a call while using hotspot and browsing from my laptop. As soon as the voice call was made I could no longer browse the internet using hotspot... basically same as it always had been. I was frustrated to the point of seriously considering returning the phone to verizon.
Then I went back into the hidden menu and changed the radio option to "USA" (the option in upper right corner of that hidden menu.) I don't know what it was set to previously but I never leave the country so USA is good enough for me.
I rebooted again and to my pleasant surprise, it showed nearly full bars in LTE and hotspot/internet worked great all while in a voice call.
*Solution? I'm not sure if it was just my repeated reboots that did it, or if it was that last radio USA option I selected, or if it just took 15 minutes or so for Verizon to update my account to enable the HD (or whatever it is called).
Again, I'm completely stock vanilla on Verizon. But my frustration sounded very much like yours so maybe this will help you situation. Good luck

This worked for a few people and it was confirmed having the same issue ur having.
People keep bring up these steps are useless but like i said i have people confirmed this works over the other method.
Hope it helps
I followed all of the steps in the tutorials with no success. I have MultiRom installed along with ElementalX as my kernel as it supports MultiRom. I installed Scott's 5.1 stock rooted rom as a secondary rom and made sure the settings were correct for VoLTE. HD Voice was working as well as voice/data over 4G. When I booted back into Euphoria, everything worked great. This is what worked for me, but your mileage may vary. It's crazy that people are having to do so many steps and workarounds to get the features active on the same hardware and essentially the same core software.
Hi All,
First off all a thank you in advance for any assistance given.
I purchased my beloved phone from DX.com, it came down from Singapore so i knew a gamble was being taken. I received my phone a couple of weeks later, and i couldnt get 4G. Everything else worked fine.
What i've done so far:
I have checked every setting under the sun to see if could enable 4G, every setting ive come across seem to be ok.
I have contacted my network provider and everything is fine on their end, (the sim was working fine on my previous phone)
I have check my fingerprint and phone details to check if everything is compatible, and i also updated my WW version to the latest. - see details here

Going from your user name, you live in UK? Depends what network you're on, this phone has no band 20. Which is fine if you're on ee, but other networks use band 20 for 4g... Google which network bands your provider use

My tuppenceworth, I'm on 3uk, and have no issues with 4g. I bought my rog2 direct from ASUS.
I have noticed some slight oddities between the sim slots though. Ie, my pin protected sim doesn't prompt me for the pin in tray 1. It just doesn't work. When I put it in tray 2, all works as it should. Have you tried swapping to tray 2? Failing that, you might just need a new sim?
EDIT. Just noticed you have tencent hardware, so all this advice may well be irrelevant.
I bought my from Asus, sure it had 4g to start with. Did an update and now it doesn't work.
I'm on vodafone in the UK
Update - 4g works at home. Weird as 4g was always ok on other phones at work. Must be a weaker pick up on this phone?
Odd at work, if I have phone set to 2g/3g/4g it sits on EDGE. If I put it on 2g/3g I get H+
You'd think the first would sit on H+
Annoying having to change the setting
i feel this phone 4g very week compare to my old pocophone....
Too many WiFi antennas and not enough 4g antenna? Guess it won't ever be a software fix?
Phones great, just super annoying at work I can't get 4g inside.
Go out the door and it's 4g no problem.
Everyone's iPhones, Samsung's etc.... All get 4g, just not me
