NO SIM Card Inserted

Hey,
I keep getting this annoying message " NO SIM Card Inserted " and my trick is to turn the Airplane mode on/off for a couple of times so the SIM card is recognized again. But this is getting worse, I'm having this error the 4th time today and having to switch the airplane mode on/off for countless times before it works.
Anyone else having this problem?
Should I get my tab to service?
Samsung Galaxy Tab 2 7.0 P3100, Android 4.0.3 stock

Noboby having this issue?

I have it too. I think it's just the default message if there is no sim card inserted. When you put one in, it goes away. I don't really mind it. What I DO mind is a "--" symbol in the bottom notification bar. I used to be able to see the Weatherbug Temp or the Battery status percentage there, now I can't. Can't figure out how to get rid of it. (--)

Maybe I wasn't that clear, but I have an Orange sim in it.
Yesterday this problem with the sim was worst than ever so I'm going to Orange for a fix. Hoping that another sim will just do the trick.

i got a broken sim once after some rooting and flashing custom rom's
in my case it was clear the sim (because everithing worked well with an other sim)
and my sim was relay old (around 7 years). So try with another from a friend and you know. :good:

So it seems that I had a faulty sim and everything is ok since I got a new one. Problem solved.

Nexus 4 - SIM problem

Hello,
I just got a Nexus 4 16GB (had a 8GB before) and I've to reenter my PIN code almost every time I'm unlocking the phone when it has been in deep sleep. (the card is locked and the phone is disconnected from the network)
I first thought it's caused by custom ROMs, but it's even happening on stock ROM/kernel...
Am I the only one with that kind of problem ?

If you get the sim pin wrong a couple of times, the card is locked and you need to call your provider for a personal unlock code.
If you keep trying to unlock it eventually the sim will simply become inoperable and you'll need a new one.

I can unlock it without a problem after entering my correct pin.
So it is not a problem with the SIM or my provider.

Go into Settings > security and then there should be an option along the lines of Sim card lock. Try checking in there.

Disabled the pin lock for now.. But the signal still drops when the phone is longer in deep sleep.

I had the same problem!
I don't know if this is rom or kernel related, but since I switched to ParanoidAndroid it's gone....

Ah finally someone with the same problem.
I've already been running PA, but the problem did still exist.
Did you change anything else beside that?

i removed my SIM again and cleaned it.

i've also had that issue the second day after receiving the phone. I removed the sim, put it back in but that didn't help - i looked at my sim card tray and i realized that a one side of the sim card chip was close to one metal side of the tray and i figured that could be the issue - so what i did is i took a stripe of adhesive tape and made sure they wouldn't touch - I haven't had the issue again and it's been more than 2 weeks.

Uh...I remember a kernel arg from my old HTC Topaz WiMo-Device, which was able to run XDAndroid.
The argument was pm.sleep_mode, and it is still available on the Nexus 4 and set in the system/build.prop
It controls, how the device handles locking, usually it is set to 1, but, i think, it goes from 5 to 0, where 5 is "stay on all the time" and 0 is "shut down everything when locked".
You could try to swich it to 2 or 3, maybe it helps.

I got a replacement phone which is working fine now.
Thanks for the tips anyway

hmm got a 16gb one and the Sim keeps disconnecting even without deep sleep.
might need to send it back too. poop

Hi,
I got the same problem too.
Sometime, it's getting worse and worse so I have no other choice but to reboot the phone --> When I put my PIN code and press the validation button, the screen doesn't go to the main menu but asks me again about my PIN code. Infinite loop...
I cleaned the SIM card 15min ago and no problem since (fingers crossed). I read an alternative version of android solved the issue in one case but not always. I won't take that risk if I have to send it back to the manufacturer. Before I do that, could you suggest me something else to try ?
Many thanks for your help.
Best,
Valentin

I had the Nexus 4 since December and yesterday for the first time the phone asked for the PIN code and lost the connection to the network. And like posytryon I had to enter the PIN more than once (in my case it was "only" twice). This morning it already happened twice again. Never rooted the phone, stock Android on it. What is going on?

Why are you people so paranoid? I've never used a lock on mine. In all these years....
Just asking for trouble using sim lock IMO.

What kind of silly reply is that? Why is it asking for trouble using SIM lock??? And if you read through this thread, someone had the same problem of the phone not connecting anymore even without SIM lock.

I pulled my sim yesterday because I switched users now it says no sim I put old sim in same problem flashed new rom nothing...
(CRAZY TIMES)

I'd noticed the same thing, and insulating the SIM from the holder resolved the problem for me also.
I also found an app for monitoring and alerting if the phone switched back to asking for the SIM PIN, this might be useful for others.
SIM Locked Notifier - https://play.google.com/store/apps/details?id=org.slaytanic.SIMLockedRingNotifier

Finally put some adhesive between the tray and the SIM card. Worked perfectly for me too, no SIM problem for 10 days now.
Thank you so much, Lucker#1.

No Sim Card

Hi everyone,
Yesterday my phone stoped to recognise the sim-card.
At first i got a message with sim-card problem and the phone need to be restarted.
After that sim worked a day and now i cant use any sim in this phone. I tried it with 4 cards.
I've tried new roms , and paper on sim-card reader. Still "no sim card"!
Is it possible to repair it or is it Motherboard problem?
Thanks.

Have it checked in a authorised Samsung Service Centre mate. I had that problem twice in one day few days back, but since then its running fine! I was really scared, thought I would have to visit SC, but it went away on its own! I don't think Motherboard needs to be changed, only the SIM slot if its damaged.

Thanks for your answer. My phone doesn't recognise any card now. Since 2 days. I don't think it can go away on its own

Got the same problem. Probably your sim card slot got some loose like mine. I put a little piece of paper into it on the back of sim card. It caused that my sim card was inserted tighter into slot and it is working again.
It occured that it was the sim card problem. I had it again but it was strange because it worked on my sony xperia sp. But my note 4 didnt see it. I checked other sim card and it work flawless

[SOLVED ]Nexus 6P - No service message

Hi all!
I've bought a Nexus 6P in september 2016, worked fine in every part until yesterday: my phone stopped showing signal strenght and says "No service" in the upper left corner of the screen.
I was on a custom ROM (Pure Nexus) but:
- Restoring factory images didn't help
- Restoring the oldest Marshmallow factory image didn't help either
- Erasing cache didn't help
- Switching to 2G and 4G didn't help
- I did a network settings reset, nothing changed
- I've switched to a new SIM card, nothing happened (old SIM card worked well on other phones, like this new one)
- I've never touched EFS partition but my IMEI is still there, so i don't think it's a network problem
So... Any ideas?

Oh man... I was hoping it was just me. This has happened to me too within the past few days, twice.
After waiting a few minutes it came back. It *May* be they are doing tower work. That's what I'm hoping.
I am on Verizon Wireless on the 3.79 radio if that helps add info to the pile. What radio are you on?

I'm on the same radio, latest radio in latest 7.1.1 release, january security patch, as i said before, installing the oldest Marshmallow release (so the first radio released by Google) didn't change anything!
My provider is Vodafone IT, I don't think they are doing some tower work, because everything works fine on other phones and the same SIM card in!

Good day,
Got same issue few days ago, after phone restarted due to installing January security patch. Phone was not rooted on stock firmware 7.1.1 with locked bootloader.
Cellular network don't work at all, if try to find network manually it return: Error while searching network.
In *#*#4636#*#* all switches in OFF position and cannot switch on. IMEI available.
Also when try to make a call(without network of course) it return: Turn off airplane mode to make a call. Of course it not turned on.
I try flash vendor, bootloader, baseband/radio(3.72, 3.78) previous stock firmware 6.0 and 7.0.
When flash cyanogenmod 14.1, SIM card was not detected.
Carrier Elisa (Estonia), bought in November.
Any ideas?

If you're not on Verizon, I would just switch back to 3.78 radio. Flash it manually. Don't see how that wont fix your issue

Hi mate, a friend of mine have a Nexus 6P, we are on the same carrier and the same 3.79 radio, everything works fine on his phone!
So my problem is not radio realated!
Radio 3.79 is also good for other carriers over Verizon.

Hardware problem with Huawei. The gold contacts on your SIM card are not making contact as they should. Likely a problem with the SIM tray.
Eject SIM card and put some scotch (cello) tape over the card to hold it in the plastic tray. You may need two strips (I did.) Now reinsert the SIM tray. All should be well now with your cellular connection.
Added thickness of the tape holds the SIM contacts to the connectors inside the phone tighter when the tray is closed and the problem is solved.
I did this about three months ago when I started having this problem and have been fine since.

Yeah, me too, I've bought my Nexus 6P trough eBay and was a private seller, it seems that private sellers are not required to provide a warranty...

If you buy from EBay your only warranty option is Square Trade but if your phone was bad when you got it you can file a buyer protection claim

UP!
Noone else had this problem?

It seemed like other people did report having the same problem and their solutions, if they had any. Maybe you should contact your carrier. They might see a problem on their end.

I know you tried an old SIM, but have you been up to Vodafone to get a new replacement SIM as the next step? In my experience they are happy to replace at no charge. If Vodafone IT's new SIM doesn't work, just try a 3 ITA or TIM.

had this issue ONCE, and flashing the proper vendor file again fixed it.
no idea how or why

Thanks but I've already re-flashed factory image, so vendor is built in the restore procedure!

So I had an interesting experience with the same thing. Was running a custom rom that is very close to stock and updated to the most recent security update. Shortly thereafter, my carrier connection would drop (didn't notice at first because if I was connected to WiFi, it would be hard to tell). Only a reboot of the phone would fix it, for often no more than an hour or 2. So I started by wiping the device. Then I went to a different custom rom. And then finally, I went back to stock using "flash-all.bat" from the factory image. But alas, the issue continued. The last thing I did, which seems to have resolved it so far (12+ hours without a disconnection), was to relock my bootloader. Just in case it helps someone else. Is it possible that the new radio + an unlocked bootloader is causing the issue?

locked and unlocked bootloader,
hard factory reset,
flash google factory image and erase all internal storage,
wiped dalvic/cache,
flash vendor image,
flash different radio and bootloaders,
but still no service and no data. i think it's hardware issue and i have no warranty

Not Recognizing Sim Cards

I have an unlocked sprint LG G6 I got this past fall. I've used it as a WiFi device until now but wanted to make it my daily driver for a while. For some reason it isn't wanting to recognize sim cards.
I did a factory reset and it recognized my sim card then upon a reboot it no longer will no matter what I do. It just says no sim card no service. Another hard reset trying the other sim card fixed it again but once I restarted the same thing happened. Upon restarting it does give a message saying "The sim card tray must be fully inserted to help prevent water damage. Make sure the sim card tray is not inserted upside down" but it's inserted correctly.
Has anyone experienced this or have any ideas? Thanks.

have you found the fix? been having this issue since i bought it. hard reset works but restart does not! so if your phone is dead of battery, then you gotta do hard reset which is a pain to transfer data/reinstall etc..

No one has had any suggestions. I contacted LG who only offered for me to send the device in for repair which I may do next month.
