Hi,
Just writing this if anyone has an idea.
Some weeks ago, I bought a Nexus 5 for my daughter. It was a used device, but in good shape and perfectly functional.
My daughter is a bit clumsy... After 10 days I gave it to her, she said "Dad, I have no connection anymore".
And indeed, the carrier signal sign showed "empty".
Here's what I did to troubleshoot the problem (at least to try to troubleshoot it as it is still there) :
- 1°) swapped SIM cards : put mine into her phone and hers into mine : result, her SIM card is working in my phone ; mine isn't working in her phone ;
- 2° re-installed a Google Nexus 5 "Factory image"... so system is brand spanking new here
Here are the exact symptoms :
- 1°) with no SIM card the phone shows "Missing SIM card" symbol ;
- 2°) if I insert a SIM card, the symbol changes to an "Empty signal" symbol ;
- 3°) a message says : "No connection"... but this is followed by the carrier's name...
So I suspect that the card is working and is recognized, but that the antenna (or what ever it is) is not connected anymore.
Anyone knows if there's a simple fix to this ?
My daughter said she dropped the phone a couple of times (as I said, she's a little clumsy !).
Any help would be appreciated from this great community
Regards.

Hi there,
Just replying to myself.
After doing some researches, I also tried to enter my carrier's APN manually.
That did not help unfortunately
Any other suggestions ?
Regards.

A few key details:
I purchased my device via Google Play.
I'm using a SIM card provided by Sprint.
I'm not rooted. This device is completely stock.
I've tried reseating the SIM card as well as Factory Data Resets.
That said, here's my issue.
Every time I boot my device, even after a Factory Reset, a while after it's been connected to 3G (it also won't connect to LTE unless auto-activation is in progress, that's a whole separate issue), it displays an empty alert box with a SIM card icon at the top. After closing that box, it displays another one that reads some error about my SIM card being locked and that I need to power cycle the device.
I've tried everything and this error is still popping up. I'll be contacting Sprint later today about the issue but I figured I'd come here first to see if anybody knows about this issue.
Pretty frustrating, Sprint sucks, yada yada... the basics. Can anybody help?
Have you tried unlocking it yourself online under your account's page?
There should be a link next to where your device is listed.
"Get my PIN1/PUK1 unlock code" should give you the required codes to unlock it.
Might also be a bad sim card.

Does that Sim card was already activated on another device? Or did they gave you a new one?
There is a similar problem when people try to use a sim card from a current device, that will trigger that same message like yours.

Hello all!
I am in possesion of a Galaxy S5,that has a very special problem.
It got to me restarting periodicly (15sec to 3 minutes) an a forbidden sign instead of signal icons.I tried houndreds of firmwares,most of them failed at writing in odin.When I type *#06# in order to get the imei it shows null/null,and also it has no baseband(signs of missing efs partition).Here it comes interesting: after some charging cycles,it suddently works,shows the signal icon and missing sim message..if i restart in order to put a sim in,the problem gets back.It worked for a day in a particulary case with a sim card in,but he restarted when i put in the mobile data settings,and then it get back to the null imei/unknown baseband.
Please give me some answers or solutions...Im desperate
Best regards to all of you

People,
I hesitate to ask the question again, but I promise you that I've read everything on the subject that I can find (including many of the 171 pages of the "Nexus 5 Flashable Modems and EFS Backup" thread...) and also on a lot of other sites.
My son's N5 on 5.1.1 ran out of battery a month ago (it worked perfectly for the 15 months that I had used it) and when he recharged it he'd lost mobile data. He had the mobile service triangle in the notification bar, but empty. No service.
I have tried absolutely every suggestion that I've read. Airplane mode on/off. Flashed 3 older radios. Installed older Lollipop & Kitkat 4.4.4 from Google Nexus factory image site. Installed the latest nightly of Cyanogenmod. Installed MPZ79M. Rooted it. Nothing works.
I don't believe it's a hardware problem - when I remove and replace the SIM the notification goes from the square with a diagonal bar across it ("no SIM") to the empty triangle. But as soon as I reboot (not just screen off & waken, but full restart) the triangle is replaced with the "No SIM" square again. The same reaction happens on the initialisation after a factory reset - at the "Register SIM" screen it says "No SIM", but extracting and replacing the SIM starts the "Attempting to connect to service" sceen, though this just does nothing until my patience runs out and I skip it. The SIM itself has 3 scratches along it, so all in all I don't think it's a contact problem, but something in the software. The SIM works fine in the Nexus 4 that I've given him.
EFS - I don't know enough about it still, but the phone displays the correct IMEI, so I'm hoping that this means that the EFS is not corrupted?
I know that this is a well-known problem, but on the off-chance that somebody has read a solution that I haven't found...
Thanks for your patience and any help you can offer.
Oh well...
...I guess I have a £350 paperweight?
I suppose at least I can use it as an entertainment console, since wifi seems to be ok. But a terrible shame to waste such a beautiful device.
Maybe you already tried it... Just to be sure:
a) You have incorrect APN configuration, to solve this try resetting your APNs via Settings > Wireless & networks > More > Mobile networks > Access Point Names and then click in three dots above and select "Reset to default".
b) Your mobile phone antenna unit is not working properly, solving this is pretty easy, shutdown your phone, remove your phone's back panel very carefully (using a plastic material..i did it using guitar pick) and then you'll see two wires adjacent to edges of your phone, just remove and refix them gently and reboot your device.
c) Reboot in safe mode and try to play with the preferred network type.
d) I had this problem "No service and no signal network in nexus 5" after restarting phone.
I tried to restart phone few times again and reinsert sim card. No luck.
Then I took sim card out while phone was on ( I forgot to turn it off) and reinsert it and now it's working fine.
It must be a contact problem. Just not shure how long will it work.

Thanks, Primokorn, I'll give your suggestions a go - appreciate the ideas.
I have tried the APN settings, but since there's no SIM (huh!) it's greyed out, though it's temporarily updateable if I extract/replace the SIM while the phone's on - but it's grey again on the next reboot.

Primokorn,
No luck. I tried all of these with no result at all. It looks as if this is a very serious flaw in the Nexus 5 - I had my doubts, to be honest, when my son said it started after the phone ran out of battery, but I see exactly the same explanation from other people in the huge number of threads reporting this no-radio problem. How can Google issue such a good phone with such a lousy bug in it...? No point in even asking them (though I've seen at least one person who tried with an impressivly helpful response from the Google support person) since not only is the phone out of warranty but it has been rooted.
Oh well, I enjoyed it while I had it...
Heres whats going on
I have reset the N5, and flashed the July MM image. Everything flashed fine.
I insert SIM before booting, Android doesnt see SIM... so i pulled out the SIM and reinsert while on, and it sees it.
The Signal goes into an empty triangle... It says you have voicemail. And nothing else happens.
No data, no service. *#*#4636#*#* shows the right selection, it gives me the option to turn on the radio, but if i click it, nothing ever happens.
Under phone info, it sees my phone number, the IMEI is fine, and its not blacklisted when i check multiple carrier's websites.
I just cant seem to figure out why it wont just acquire service signal even when APN settings are right.
Anyone got any tips, tricks or solutions to this?
Possibly damaged sim card or sim card reader?

dont think so, i think its software maybe.... When i do *#*#4636#*#* it will show my phone number on the top... if i remove SIM, the number becomes "unknown"... so i dunno
If it happens with all SIM cards, it could be a damaged sim reader as different areas of the SIM card contains different information? Not sure.
I have similar problem with MOB30P on T-Mobile network. The 4G LTE would work just fine (I can browse web etc), but the voice is where it is failing hard. I would have dropped calls along with calls not coming through (both calling out and receiving calls).
I downgraded to MOB30M and everything appears to working fine now. I have not opened any bug against Android yet, because I am not sure if I am the only one experiencing this problem.
Hi, I was googling for a problem like your one. My N5 does not recognise the sim at boot, but only if it is "hot". If I put it in the fridge for ten minutes and then reboot, all works fine until the next shutdown. I'm sure it's an hardware problem (already tried different sim) so I disassembled all the phone, and it looks perfect. With some cleaner for electrical contacts it can survive for some days, and then starts again. So sad, I don't want to change phone just for this stupid problem XD
I'm getting exact same issue with my Nexus 5 since CM13 0803 update, which brings MOB30Y to my phone I believe.
At first my phone could still recognize my carrier (China Unicom), but there is no signal.
Then I flash radio image from MOB30Y and the phone now cannot find SIM card completely.
Even reflashing factory image doesn't help.
I'm now trying to reflashing MOB30P to see if it helps.
Update to latest August security update radio and bootloader
Hey!
I have a strange problem with my Mi4i (MIUI 7.5.2.0). The phone shows "no signal" or "emergency calls only" with a specific sim card, which works in other phones and used to work in the phone in the past.
The device works well with other sim cards too, even from the same provider. Just not with the specific sim card, which happens to be the one i would like to use. I cannot remember if the problem occured after an update (ota only).
I have tried so far, without any effect:
- a factory reset, without deleting the personal content.
- ordered and tried a new sim card from my provider
There seem to be similar threads in this forum, but they do not adress exactly my problem afaik.
Does someone has an idea what else i can try? I will provide further information if needed.
Thanks in advance!

Might be an unsupported band. What phone have tried the sim with?
Thanks for reading . Oneplus One, iPhone 5C. Sorry i forget to tell the sim card worked in the Mi4i. I didn't use the phone for a while and i might have updated it (ota) when i turned it on again recently. I guess the problem persists since then.
Any chance the update caused it?
did a full wipe and reinstalled miui (7) in fastboot mode. no change. the sim card works fine with other phones. the phone works with other sim cards fine too. just not with my main one
