[Q] SIM card error! Please Help

So out of nowhere today, i awaken my phone and I see an error "SIM card removed, reboot phone" I reboot the phone and now I have no signal and a SIM card symbol in the notification bar. I didnt remove the SIM so I dont know what happened or how to fix it. Anyone know how to fix this?
EDIT*** Nevermind. I removed the sim, then put it back and that solved the problem. Probably should have tried that before posting lol

happened to me a week ago. I was puzzled. I removed the sim and battery at the same time like 10 times. So I flashed back to stock and took it in. The guy plugs the phone in (probably checking for root) and then unplugs pulls the sim and battery and turns it back on. All working like nothing happened.

[Q] No SIM card - Emergency calls only

Hi, everyone, sorry to bother you, but I'm in a bit of a pinch.
My unrooted stock Nexus 5 was running smoothly with then latest OTA update 5.0.1 until I got No SIM card error. I eliminated SIM card as problem source, removed SIM, discharged it completely and after few days turned it on and it was working. But problem returned soon and same method didn't show result. So things I already did:
- check my card in other phone: works
- check other cards in my phone: doesn't work either
- left it off without SIM for a few days
- erase cache
- upgrade to OTA 5.1.0
- factory reset
- unplug battery from motherboard for some time
- flash stock 4.4.4 from developers google com
- put some tape on card to make contact better
in this order. My next move would be to check if SIM card case pins are broken. Warranty expired month ago so there's that. Do you have any advice to give me? Is there any part of the phone that could've stayed not wiped during 4.4.4 stock flash and that's the reason problem remained?

You have a weather widget, clock, GPS location app that is causing the issue. Try uninstalling one at a time until you find the culprit. For me it was transparent weather clock widget that was causing this. Something about the way the app polls the GPS location causes problems.

I flashed stock 4.4.4 and only stock apps are present. I can either uninstall upgrades or root and delete gapps for good. What say you? I think phone somehow got "stupid" hard and I have to reset certain part that wasn't affected during flashing because it haven't once worked throughout process.

My nexus 5 is doing the exact same thing, exactly as you described, since the update. I'm losing my mind
Seeing as we both have the issue I don't think its a problem with your phone in specific. If anyone knows please help! I've tried uninstalling every app, going on safe mode, swapping sims etc

If it happened immediately or just after update try flashing stock KitKat.

Got the same trouble
The problems begun 1 week ago with interruptions with the radio, i have to restart the phone with Stockrom 5.1 self flashed and uber-kernel to get any connection. Switch the airplane mode often to get any radio signals. I ask my provider o2-germany for some trouble in their radio stations - and there was, just a few hours it worked. In a few days ago I traveled across germany, from the south to the north and back, got while traveling no good receptions, only gprs and edge. And now I switched from stock-rom 5.1 to OptiPop 5.1 the trouble begins with no-simcard ...
I will try xTraSmooth 5, when this ist not working i try an older image...
Edit:
OptiPop working now without flashing UBER Kernel. Now Issues so far!

Mine is absolutely stock on 5.1, not seen it once in 18 months and now it has done it twice in 12 hours.

I've always been completely stock and my phone started doing this every time I reboot it. Any more word on this? It also does seem my GPS looses lock on a lot too. This seems to have started since the last OTA update a few weeks back or so.

after i flash latest factory image mmb29v I got No SIM card error. There is an error in Safe Mode and SIM card not detected .pleas help me

N5 has No service, No data and SIM card sometimes not recognized

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

[delete] Sim card stopped detecting - Android P beta

I was on Android P beta build, today morning I felt a small lag in the UI and so I restarted the phone. Data connection was turned on and being used during this period of time. But since after the restart, my SIM card is not detecting. I powered off and on restarted several times but no luck. What is the next possible diagnosis to sort out this issue.?
I am from India and my operator is Idea.
Edit: Issue was with my operator. They provided me duplicate sim card and the issue has been resolved. Please delete the post.
