My N4 got here today and put my t-mobile sim card in, but I'm not getting any service at all. Even with the sim card inserted, it still says "Emergency Calls Only." I tried connecting to tmo manually in the mobile networks page, but it just errors without connecting. What's strange is that on the phone status screen, my phone number and IMEI are displayed correctly so I don't think my sim card is the issue.
It shipped with 4.2.2, so I tried reverting back to 4.2.1 since I saw a couple comments about how the 4.2.2 update was causing reception issues, but still nothing. Tried flashing different radios/kernels/roms, but can't seem to get anything to work. I'm not having any other connectivity issues (wifi, bluetooth, etc) either. Could anyone shed some light on this issue? I'm stumped.

Did you get the N4 from Google Play or T-Mobile? If not, check that the IMEI is not blacklisted.
http://www.t-mobile.com/verifyIMEI.aspx
Is this a MicroSIM, or a cut down MiniSIM?
Cut SIM's known to have issues.
When you reverted to 4.2.1, did you flash the radio image as well?

Unless you need LTE, I would re-flash JDQ39 and re-lock the bootloader
https://developers.google.com/android/nexus/images#occam
If T-Mobile shows in a network scan, you should be able to connect. Visit a T-Mobile store to swap SIM's, otherwise you may need to RMA it.
I bought it on ebay. Checked to see if the IMEI is blacklisted but according to T-Mobile the IMEI is clear for use.
I am using the same sim card from my galaxy note, but I had it cut at a t-mobile store. The guy even verified that it was cut properly by putting it in his galaxy s3 and it worked fine.
When I reverted to 4.2.1, I tried using both radios 0.48 and 0.33, but neither did anything.
I'll try your last suggestion and report back.
Thanks
The N4 is super picky about cut Sim cards
Even if it works on another phone , it probably won't work in the Nexus .

Make sure the gold contacts on the back are all getting touched , you should see lightly indented lines on the back from putting it in your slot , if it doesn't work try to get a precut micro sim from T-Mobile

Hi, My Nexus 4 got no service already 1 week++. I already tested with the other SIM card and I also do a research on Internet. On Internet, also got many people faced this problem. On Internet, many people said the nexus 4 cant accept the SIM card that is normal SIM card cut into micro SIM card, must use the original micro SIM card. I also try with the solution and I bought a SIM card that is original SIM card but the micro SIM card also doesn't work. All the SIM card are cant detected by he nexus 4, will the Sim Card tray broken. My phone are protected by cover since day one and never dropped into water. I wish LG can fix this problem and help me to fix this problem, this really cause me a lot of problem. Regards, Tang.

For what its worth
I cut my micro sim ( with a punch ) and it works fine
check in settings if you have a baseband installed sometimes it uninstalls by itself so that could be the problem

Hi, thanks for reply.
Where to check, in setting app? Or Installed apps?

Settings > About phone > Baseband version
Does the phone ask you to insert SIM, or are you unable to connect to your cell provider?
If you are asked to insert SIM, you may have a bad SIM slot (broken pin contacts), or the SIM is placed incorrectly in the slot.
If you just have no service, check your phone number is displayed correctly in "About phone" and try to scan for available networks in:
Settings > Wireless & networks (more) > Mobile networks > Network operators
then use "Choose automatically"
Will the sim tray broken. My nexus 4 is running JB Stock and no root.

You need to flash a radio.

Had the exact same problem. Had no service at all (the network icon was just a triangle), no baseband, no IMEI. This is what I tried so far. My phone was stock 4.3 before my experiments :
1. Tried toggling *#*#4636#*#*, tried all the options there - no luck. Radio was "off", and no matter how many times I tried to click on Turn On Radio, it wouldnt start
2. Tried switching Sim cards, from same operator and from a different operator, no luck
3. Did a factory reset using the settings menu - no change
4. Finally, rooted the phone using http://forum.xda-developers.com/showthread.php?t=2010312 (First time ever, complete noob here). Everything went smoothly. Installed all the standard stuff from the 4.3 image.
Now, I could see the radio intermittently turn on and off - what a relief ! Atleast I knew there exists a chance this is not a hardware issue. I was getting service for 10 seconds, then it was going off for 10 seconds. This was happening continuously.
5. Tried *#*#4636#*#* and toggling all options again, (even GSM only, WDCMA only, preferred etc). I am in India and using Idea Cellular.
6. Searched like crazy on the xda forum for possible solutions - decided I'll try out a different radio version (I had 0.84 on mine) from here : http://forum.xda-developers.com/showthread.php?t=2087227 - If you're a complete noob like me and dont know what the hell I'm talking about, trust me, flashing a radio is not that difficult. Just refer to my earlier thread link
7. Tried flashing each and every radio from 0.24 - 0.84. Mixed results. Except for 0.83 and 0.84 all other radios atleast maintain signal throughout. However it never turns "blue" - I cannot access the internet from my phone - I have a data plan, the apn information is correct and every other setting is proper (airplane mode off, data on etc). The other odd thing is I can call and receive calls, however there is absolutely no audio !
By elimination - I think there are only two options here - either this has something to do with the 4.3 update altogether, or this is a hardware glitch on the nexus 4 which is activated by some unique sequence of steps. Please note I did NOTHING "illegal" on the phone before this problem - no rooting no custom software, not even any apps which mainstream users would call "shady" - just the usual FB, Mail apps, my corporate mail account.
Any ideas here - I am going to go ahead and try flashing my phone back to stock 4.2.2 again, and hope that works !! Please help ! And apologies for the tremendously long post first up

NoobNexus

In the off-chance you might still read this: I'm having the same problem, just as some other Nexus 4 users: http://forum.xda-developers.com/nexus-4/help/nexus-4-service-t2501076/post61681896#post61681896
Was this issue ever solved for you?

i recently buy a nexus 4 from ebay, only for nostalgia, so, when i receive the cellphone, i turn on without a sim inside, connected to wifi and the phone request for 3 upgrades of security, the nexus was in 5.1.1, the last than ir support, so i accepted the upgrades and the nighmare start, when i put my sim, the nexus not recognized it, i try everything, put in airplane mode and back and nothing, full reset from recovery twice and nothing.
So, i unlock the bootloader, install a recovery (clockwork) and root, after download from google the formware 4.4.4 for nexus 4, start the downgrade, when my nexus wake up in kitkat with my at&t (mexico) sim inside, the same problem, still not detecting simcard, i connect to wifi and the cellphone request for an upgrade, android 5.0.1 , click in next and the nexus start downloading and installing the upgrade, after 15 minutes, again with the sim indide, wake up with lollipop and the signal come back again ¡¡¡¡¡¡¡
My nexus after 24hrs is still with signal, whitout problems, but still request for the other 3 upgrades ( android 5.1.1 and other two upgrades for security), but with previous experience.... i will keep in 5.0.1......
Using Cyanogenmod M12
4.4.4
Have been using cyanogenmod since a year. Updated to M12 a month ago
Phone was working perfectly when the signals stopped. I restarted the phone and signals came back. This happened once more, then I couldn't get signals.
Then I took out the sim card, reinserted it, turned on the airplane mode and then turned back to normal mode. Signals came back but then signals started dropping until they disappeared.
I haven't been able to restore signals until then.
No recent updates /damage
I tried the sim card with other phone, sim card was fine.
I have been using phone since I bought it slightly used in 2012
I have also checked with my country's telecom authority, phone had not been blocked.
Any suggestions?
Hello,
I own a N910CQ for 1.5 years now.
Two days ago, suddenly my phone started to disconnect from the network. Neither incoming/outgoing calls nor mobile data works *seamlessly*. The network connects momentarily and disconnects not so long after.
Some non-authorized fixer said that that was a typical Note series problem and asked me if I wanted to proceed further because he had to remove the front glass to try to fix it. I did not allow him to do it so I am stuck with a working but useless Note 4 right now.
Have you ever encountered such issue and if so how did you overcome it?
Thanks in advance.

Go to settungs/back up & reset and factory reset erase everything and try diffrent sim card also.maybe software or sim card issue.
No luck.
I switched from Polish ROM to Turkish one (both 6.0.1), do you think modem files might be causing such issues?
Fixer said nothing visible seemed like the root of the problem and that if I took it to a Samsung Service they would most probably like to replace the motherboard and that would cost almost as much as a new phone.
Hi XDA
So i came across a very serious issue 2 days ago basically rendering my phone almost useless as calling is very important to me.
I have been running purify CM13 rom on my samsung note 3 N9005 Snapdragon flawlessly for 2 months and out of the blue yesterday my phone displays Emergency calls only- then my service provider name, i tried the sim in another phone and it worked i also tried other SIM cards form other service providers in my phone and they all show the same thing but the phone can actually identify the network provider also when i remove the sim it says no sim inserted.
Hours upon hours of googling and troubleshooting and still no luck in fixing this issue whatsoever. I tried a lot of stuff like resting the APNs, manually setting the network, Switching form 3g to 2g and even wiping my device and flashing the newest version of the rom again but the problem still presists.
At this point i have no idea what to do, any help is appreciated.
