Today i went to the gym, and when i was done and picked up my phone in the locker i needed to call someone. I called but it froze during the attempt to call so i turned the phone off (i could turn it off normally, so i didnt pull out the battery). When i turned it back on i had no signal at all, and went to mobile networks settings to check. I got the message that i had to insert my sim card to edit the settings.
My phone was running JM5 rooted. I tried switching sim card to see if my sim card somehow stopped working during those 2 hours but that didnt help either. I then tried reflashing (now have JM7 on it) and i still have the problem where it wont find my sim card.
Is there anything i can do besides send it to be repaired? I'd prefer not to do that seeing as i really hate waiting for it to come back.
You have probably tried it, but I'd get a cotton bud and clean the contacts both on the phone and the sim card. I've had that happen twice, but not on my SGS.
Yea tried that already.. thx for the suggestion though.
I guess i better hand it in to the repair shop.
I also have this issue with my SIM card, i go to flight mode and return back to normal mode seems to fix the issue ive also cleaned the contacts before and it didnt seem to occur again..

Yeah i have tried that, it's not working either. Tried several different Roms and different modem/radios too. This sucks.
I have the same problem. It started after I flashed JVK on my phone. I thought it was the firmwares fault, but I still have the same problem after flashing JS8. I think I'll be asking my provider for a new SIM. I have a feeling that the SIM might be the answer to our 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.
I have just received a Nexus 4 off ebay today. Said it was a month old, unlocked etc.
I got it for the Mrs. She powered it up, and inserted her O2 sim and it said "no service".
We haven't done a thing to the phone but turn it on. Is there a reason for this?
I've attached the software details.

Have you tried to set the Settings->Wireless&Networks->Mobile Networks->Network operators on "Choose automatically"?
It may have been set to another carrier by the previous owner.
Clicking set automatically doesn't seem to do anything. And when she clicks mobile networks, which usually shows a list, nothing happens.

Have you tried adding your APN manually

http://www.geeksquad.co.uk/articles/chapter/595-04-how-to-set-apn-settings-for-the-02-mobile-network
Take the sim out and make sure its in properly, then re insert and reboot, and try again to find network, try choosing o2.
I had this problem and it just seemed to fix itself while doing the above
Wait is the IMEI present in settings?(don't post a photo)

It does come up with a IMEI when I go into settings. As you can see from the attached, there is no signal at all. I've tried mine and her sim. This phone looks brand new, the guy said he used it for a month, it's running 4.3. Everything works but this.

Did you update the APN or are you just going to keep telling us that the guy used it for a month and that it looks brand new?
Whats the point of even putting in an APN when I have NO signal and it can't even scan for networks.
Secondly, I think it's faulty. I noticed the sim tray isn't sitting flush, with or without a sim card inside. And more worryingly, I just tried the to add an APN, it didn't even save, and there is this rippling effect on the screen if I press the back of the phone, or front. It's in the exact same spot. Even holding the phone in the hand and gripping causes the effect, It's like an invisible stick is poking at the screen, distorting it. Hard to explain.
Maybe all this is irrelevant, but I'm suspicious.
Have you tried performing a hard reset? It could possibly be blacklisted, amongst other things.

Looks like the IMEI is blocked. This can mean the phone is reported stolen and therefore the IMEI is blocked.

heres another way https://prod.eie.net.au/portal/template/MYMIMEIInquiry.vm
Thanks for that. Both tests included a seperate paid one, show no problems, no blocked IMEI.
The only road I can think of to go down now is the whole unlocking bootloader, flashing other modems/roms etc.

is that micro sim working in another phone? if your sim card works in anotger phone, then the n4 itself is the issue. my first n4 i returned within a day, it wasnt reading any sim cards at all.
Both sims work fine in other phones. I'm so annoyed by this, it's near mint condition. This guy had to know it was faulty surly.

it could be the phone itself then. the n4 has a known issue with faulty sim readers. btw, was your sim cut down to a micro size or is it an actual micro sim?
btw, this simms works fine too
It's a proper micro sim. I just want to be sure that it's nothing my end before I start moaning and getting refunds. But at the moment I think there is no other option. Would trying to flash another radio make a difference? Or is it futile?

the radios might play a role for a little better or worse reception, but one wont not give you a connection and another will is highly improbable.
It's imei related. Since you stated it's present & not erased, that means it can't register with the network due to a possible blacklist.
Also micro Sims and normal Sims that are cut will both function in the nexus(I've tried both).

Hi guys, this morning I noticed that I couldn't make any call or send messages and I discovered that the "not inserted sim" icon was showing on the status bar. The problem was that my SIM card was inserted. I'm not sure but I do think that this is likely to be an HW related problem and I've also red that I'm not the only one who faced it. The only thing I can think of is that the SIM card is not making contact entirely with the motherboard and that's why it is not recognized. However, luckily, this issue is easily solvable. What I did was apply 2 layers of tape on the SIM itself and then I inserted it back into the phone (It was a little bit hard to push in but this is probably the only solution possible). Now I'm not getting any error anymore, I'll report back if something happens again.
Do not apply more than 3 layers of tape of the SIM tray won't come out easily or at all
This guide (yeah, not really a guide, just a suggestion ) is for the people who do not want to send the phone to HTC and wait for its replacement.
What type of tape is used and did you cut the excess off?

I used the classic office tape the transparent one and yes, I did first applied it to the SIM and then I cut it the same size around the corners
I had that issue so I pulled the Sim and cleaned up the contacts with an alcohol swab. The swab was black when I finished. I haven't had a problem since. I figured it was dirt but after reading this it may have just been loose.

Just one question guys, is your phone branded?
Yep AT&T branded.
I haven't gotten SIM errors often but it does happen every once in a while.
EDIT: And then it happened just a short while ago, lol.

@matt95
I added the two layers of clear tape and will see how this holds up. I have network connectivity so it was able to be inserted in properly.
Ok I don't think my theory is correct, in fact yesterday night the issue showed up again... However I did install the ARHD and i have no problem at all, could this be SW related?

It doesn't make sense to be sw related especially if the disconnect error appears. The tape idea has some logical sense to it. It tries to ensure the SIM keeps in contact with the phone.
It seems to be working fine for me. I've had it in place since the other day. Which ROM throws the error for you?

Hi,
My galaxy s4's(european i9505) sim card related functions (calling, 3/4G data etc.) have stopped recently.
It's 3 years old but that doesn't neccesarily mean i should throw it in the trash can right?
When i reboot it, it sometimes detects the sim, but most of the times not. Sometimes it doesn't accept the pin code.
When i get lucky and it does detect the sim, it still doesn't function though.
i.e., i type in the sim's pin, but i get the following:
-no signal bars in the statusbar
-it does say it has signal strength in Phone > Status
-network unknown
-CM regularly pops up a prompt to restart in order to be able to use the mobile network, as if i just put in a new sim card.
I'm on CM11 at the moment, but the stock rom, and CM13 gave the exact same problems.
Could it be a faulty sim card module or antenna, or wouldn't it have any effect when i replace these?
The sd card reader does still work, and i have tried to push the two (reset?)pins on the back.
It only prompts again to put in the sim's pin but it doesn't have any further effect.
The slot seems to be clean, and the sim card isn't faulty, it works in my other phone.
Booting the phone in Safe Mode doesn't have any effect.
It'd be great if i you guys could advice me on this, cheers.
Do you have access to another phone to try your SIM in? If that works fine then you can rule out the SIM card being at fault.
Then I'd replace the SIM card holder, it's a simple job to do and the part is really cheap as well.

Yes, as i said in my 3rd last sentence, the sim card works fine in another device. The thing is that many people with an s4 have problems that are similar to mine, but they report that replacing the sim reader doesn't fix the problem, or only for a just few days. (some even said replacing the entire motherboard didn't fix it)
So that's why i'm hesitating to try replacing either one of these. If it's the only way i think i will try it though, it indeed isn't a costly part like you already said.

I do doubt it is a software problem.
Generally speaking, if it happens on various roms then it's probably related to hardware, or something that isn't affected by rom changes (like the modem, in this case)
Do other sims work on your phone?
