Can't find a fix to this anywhere
I can't make any calls or connect to 4G. So far I've tried resetting network settings, triple checking my APN settings, I've even got a new sim card but still nothing.
When I make a call it says 'not registered on network'
It won't even let me automatically connect in network operators.
I've even done a full factory reset but that didn't work either
Last week the phone worked fine but now the only thing that works on it is WiFi
Anyone know how to fix?
Where is the phone from?
Not sure too be honest. I bought it on eBay about 6 months ago. It's worked perfectly fine up until now.
Don't understand how it just stopped working. I've even updated it to the latest official firmware.
go to settings --> apps---> show the system apps and go to phone app and clear data of it
go to sim toolkit then and clear the data too if there are more then 1 then do it for all and try to reboot
if that doesnt work
type *#06# and check if u see ur imei
if u dont see it ur ****d up ur efs
Thanks for your reply
It didn't work though. I cleared the data on 3 of the phone apps data & 2 of the sim toolkit.
My imei does show when doing *#06#
When I restart the phone I just get a ? symbol top right. It eventually disappears and I have 2 bars signal but I still can't make any calls, texts or have 4G though
Just to confirm it IS my phone causing the problem as my sim card works fine in my wife's s8 plus. It's not the sim tray either causing the problem as I've tried hers with the same result
Anyone?
I'm desperate for a fix
Many many thanks for all your amazing help ?????????????????

Check if your IMEI is not blacklisted.
Found out it is blacklisted!
Anyone recommend going here

On what network was this phone previously used. The best thing to do is to contact the carrier and try to fix it with them
My understanding is IMEI blacklisted is usually when phone has been reported stolen, it's intended to render the phone unusable on any phone network.
Same
I have the same problem, is there anybody here can help me? Wipe data: done, reintall stock firmware: done, device info app installed and shows sim infomation with signal strength-141 Type lte, but, cell identity 0, lac 0, psc 0.
Wifi It's all right.

My IMEI still shows up and I can connect to WIFI and bluetooth. The only problem is I can't get a signal, not 2G or 3G (even LTE)
This started happening out of nowhere, I tried taking out the sim, factory resetting, wiping caches, changing the APNs, restarting the phone, and I even put the sim in a new phone (It got signal).
If anyone has any ideas I'm all ears! What's the point of this amazing phone if I can't call people with it?
How long did you have the phone before this happened? Did you dial *#*#4636#*#* to check the phone info and change the network type?
I had a similar issue, but I think mine was a lot worse due to a dirty flash. I ended up having to do a fastboot recovery to restore it to factory.

What service are you with? I had this same exact issue a week ago with an LG G2. My Sim card would work in my Nexus 5 but wouldn't work in the G2.
After numerous factory resets I eventually called Metro PCS (my carrier) and I was told that whenever I put my Sim Card into a new phone I must always contact them and give them the new IMEI # so that the phone can work.
The Metro PCS rep claimed that they have a feature that disables the Sim from working in an unauthorized phone. I guess its to help with theft.

Hi, were you able to fix your issue? I am having the same exact issue and have done all troubleshooting I can do on my own but still nothing works.
If you have a method of fixing this please share.

I know this is really OLD!!!!
but i just had the same issue today
with a NEXUS 5 running stock marshmallo 6.0.1 with the latest patches
, and yes... is not the phone is the carrier
MetroPCS do IMEI lookup
i had another phone before the NEXUS 5
so it is no just matter of swapping the SIM card from one phone to the other
you need to call CS and you told them that your phone is not registering on the network
and that you just swapped phones
So they ask you for the IMEI of the "new" phone
and your SIM card #
you reboot your cell
and VOILA!
now the phone registers in the network
Yes, Metro do IMEI authentication
Hi guys,
I've been having this problem with my N5.
Its a d820 model, unlocked and rooted.
I have no signal, cant register to the network either.
I can use wifi with no problem too.
I changed the micro sim card with other carriers, same issue. I asked for a new micro sim to my carrier too (not cut), but still getting the same problem.
It's worth mentioning that the micro sim works flawlessly. Im using it everyday on an HTC One S and signal and data works perfectly.
When I first get the simcard on the N5, it asks for a reboot, after it comes back up, it shows strong signal, but I can't make any call or receive, no messages either.
After a few minutes, the signal goes down and it shows only emergency calls.
Going into mobile networks and searching for my carrier takes quite some time, but no matter how many times I try to select my carrier,it always comes back with not able to register in the network.
I did a factory reset, and went back to stock, and then performed the system updates to 4.4.4.
I flashed a couple of radios as well, but no luck.
The IMEI shows well, and its the same that shows on the box, so I guess no problems there with a corrupt IMEI.
Has anyone else had any problem like this? Any suggestions?
I've been reading some threads here, and I still have to try a different kernel/ROM, but if anyone else knows of a similar situation, I would appreciate any suggestions.
May be it has something to do wid preferred network...
If u use 3g go to dialpad
Type
*#*#4636#*#* phone info
Select modem as wcdma only...
If u use lte select lte only... See if this works
I think I already tried that, but cant remember for sure
Will give it a shot, thanks
Is the phone second hand?
Have you checked if the IMEI is blocked by the network?
sounds like you bought a used phone that has been blacklisted. if blacklisted, your phone wont work on any US carrier, and many Canadian carriers.
Yes its a second hand phone, and I don't know if it is blacklisted on USA, but Im in South America, so that shouldnt be a problem
And there are no carriers here working with N5 so they cant blacklist the IMEI either
(This doesnt mean that the phone doesnt work here, actually, my wife has another N5 that works like a charm here)

the carriers dont have to work with the n5 to blacklist it. in other words, they can blacklist any phone that connects to their network. as soon as you connect to the network, they know your imei and other info about your phone. anyways, they blacklist your imei, so when your phone tries to connect, it cant. the agreement that carriers have in the US and Canada, could possibly be for all of the americas, or, in south america, they could have their own blacklist.

googling, i found that carriers worldwide are sharing blacklists.
The GSMA, an international association of wireless carriers, also keeps a database that wireless carriers worldwide could check to prevent stolen phones from being reactivated on their networks.

I will check on that, I think I can just call my carrier and ask if that IMEI is blacklisted or not

yup, thats the best thing to do. the people that first answer the phone, customer service, probably wont be able to help, maybe someone in tech. or, use this website to check(there art other sites as well).. http://swappa.com/esn
Well I just checked. IMEI not blacklisted on my carrier, also checked with swappa, not blacklisted either.
I used the *#*#4636#*#* to select wcdma as well as other options there, but still no go.
Also, under Mobile network settings, changed the preferred network type to LTE, 3G and 2G, but no luck
Tried Choose automatically the network, but still getting the message that its unable to register to the network right now and that I should try again later
I guess Im left with flashing some other ROM/kernel to see if it helps, unless someone has any other suggestions

also, what kind of nexus 5 is it, a d820 or d821? it would make a difference signal-wise. ones for north america, ones for europe. honestly, i have no idea which you would need http://www.phonearena.com/news/Differences-between-the-two-Nexus-5-models-D820-and-D821_id48985
I don't know if the problem is with the carrier, since I'm using the very same simcard with another phone and I have data and network with no problem.
The phone is d820, but I know it works here (my wife has the same one), network 2g and 3g work well here, LTE is the only thing that won't work here with this phone but I don't care about that
I'll keep looking just in case, and I guess tomorrow I'll flash different ROM

If the problem is wid radio flashing a different rom won't matter ..
Have u tried flashing a factory image ?
I know flashing a new ROM wont help with radio, but I've seen that using *#*#4636#*#*, going into phone information and then Select Radio Band, gives me an error and force closes.
I've seen some threads about that, and someone saying that it was working on a CM ROM, so I was thinking of trying that in order to be able to select the radio band and see if that helps.
About the factory image, yes, I used the google images to go back to stock, and then performed the system updates.
Well I flashed Slim Rom, and was able to get into *#*#4636#*#* to change radio band. Tried them all, no change.
Played around with the preferred networks and no luck either.
I'm officially out of ideas, but I'll keep digging around to see what I can find.
Any suggestions welcome.
Also, I know that there is a known issue with the GPS signal on some Nexus 5, and there are a few videos on Youtube showing how to fix it (basically opening the back of the phone, and sticking a piece of paper under the connector).
Does anyone know if there is something similar happening with the radio? Does anyone have a photo of the phone showing which part would be the antenna?
One additional thing I noticed.
If I switch, or just take out and reinsert the micro sim, the phone asks for a reboot. After doing that, when the phone boots up, I see I have network (full bars), going into mobile operators, I can see my carrier, and I can register too. But I cant make or receive any calls or messages.
During this 10 minutes that I have this sort of fake signal, if I go into *#*#4636#*#* and phone info, I can see my carrier, but it doesn't show my phone number. Weird.

i am facing the same issue with exus 5 .In my hometown in India,the phone simply shows "Emergency calls only" and shifts to normal working mode with full network coverage once i travel to other parts of my state (parts which probably has a better signal strength ,i dont know ).i have tried out changing the sim card and a factory data reset ..Both didnt help ..

Has anyone been able to track down the issue and get it resolved? I'm facing the same situation, and almost taking it to an authorized LG support so that they can change the motherboard.
So my Vodafone SIM gets detected when inserted but doesnt connect to network.
On searching networks it doesn't show up either.
Weird facts:
My SIM works fine on my Nexus 4 and other Nexus 5 (only 1 I've tested on)
Other SIMs work fine on my Nexus 5.
Tried various ROMs and radios, but same result.
Another weird fact:
Once on roaming I had connected the SIM to my N5 and the moment I left my state it got connected to network and as entered back it stopped again.
SIM has been replaced, Vodafone blames the phone and I don't know what else to try out.
Any thoughts?

In settings can you see your IMEI number ? if you don't (like mine showing 0) you never get any signal , you've got to send it back, it's bricked then...

IMEI is good, its works fine on other SIMs and mine works fine on other phones too as mentioned in OP.
What's your current network mode in *#*#4636#*#*? Try any of the modes but CDMA (WCDMA is fine).
I have the 920F model and activated it with a UK sim a few months ago.. Have been using a US sim for the past 2 weeks, but today I went into an area with no service for a bit. Went back into an area with service and suddenly it says 'Not registered on network' when I go to make a call and 'No SIM card'.
I have gone into flight mode, cleaned and checked SIM (not a problem with the card), and then when I went to check the APN settings I noticed there was no way to get into my 'Mobile Network' settings! Its just gone!
Is it possible that it has reverted back to the European region lock and is awaiting a European SIM to be inserted before I can re-insert my US?
If it is a region lock, is there anyway to unlock it without using a European SIM as I no longer have mine and dont have quick access to one either.
Any help is appreciated. Hoping there is an easier fix.
I think airplane mode disables that menu. Did you try to take it out of airplane mode again before looking for the menu?

Im currently having the same problem with my 920f. I dont think it is region lovk because i am using mine in the same region that it was produced for. If you have fixed the issue pls tell me how you did it. I also noticed that whenever you connect it to the pc, it is not being recognised.

SN and IMEI is good in about the phone, when dialing *#06#, and in service mode (*#0011#) says IMEI: OK.
As for sw, I don`t see anything that is not good, anymore.
For half a year I am trying to find a solution to this issue, tried almost everything, even writing clean cert.
Last thing I am going to try is sim reader replacement, at the begining of next month, and see if that will help.
any progress on the issue? im having the exact problem,was using it one day and it just started saying 'no sim card' inserted even tho when i put in a sim it says 'sim card added' but right after goes back to saying 'no sim card inserted' , plus the mobile networks option had disappeared from settings. also, mine does not connect to my computer and it charges slow. my technician diagnosed it as either the mother board issue or the usb port and sim card reader issues respectively. will try a factory rest and see if that's any help.
*update* factory reset did not help.
I just upgraded to 6.0.1, canadian G920W8, I put it in airplane mode, I removed airplane mode and the cell network never got back up.
Thoughts?
I was able to get my connectivity back after a factory reset from the recovery partition. I am now afraid to push on "airplane mode" as I fear I will be locked out of service again...
factory reset did not work for me, tried both from recovery and settings, any other solution?

Has anyone got any solution of this? It's been quite a long with this issue, I've searched a lot of topics but no solution.
I have the same problem. Phone don't see simcard somehow. Flashed latest original firmware works for 1 min. Pull out trace with sim insert it again works for 2 min and stops working. When it works for small amount of time i think IMEI its not blocked and almost sure its software issue. Yesterday flashed different roms and CSC and modems no luck. SimCard changed for new one. Have someone some clue what to do ? I can provide logs if needed.
After instaling Samsung Phone Info app from market gsm wen't back online. Probably a coincident but when I go to Hardware screen ther was no modem model. I tap it few times. Close apk run it again modem went show itself after a while GSM signal is back.
After reboot no signal again. Then i make magic with phone info apk again and signal want back.
This apo make some sort of device discovery and reset modem device / driver or this is pure luck.
