My phone has been playing up for the last couple of days with delayed texts but today has lost signal all together. When switching on, it says sim not recognised and then has no service. It will let me go on internet via wi-fi.
I am am currently using a turbo sim, so not sure if that is the fault or if it is the phone . It has been working for a week.
My sim card works in other phones, so that is not the fault.
Possible contamination of the contacts in the sim card slot? I have seen this before and it caused problems on other devices. Cleaning the contacts worked to fix the issue. A very, very light spray of contact cleaner always does the trick!

I've been experiencing a lot of radio issues lately. It'll work fine for a day or two, then show no signal and an 'x' in the data icon for a day or so, then suddenly start working. It's not affected by a reset.
i've flashed 4 different radios on it, and they all behave the same. i also have a Tilt and it maintains a connection while the 8525 does not.
could the antenna be loose inside? do you think the radio is going out?
Same problem here any progress? It do not have signal, then have signal...
same problem for me... please someone help us :-(
christmas is coming
Try flashing 1.48.00
Same problem here for about a month. Odd.
tighten sim card holder
I spent weeks reinstalling radios and roms and almost $100 trying to fix this problem. I finally tightened the sim card holder and it fixed all my "no GSM" and spotty coverage issues. The sim card is held in by two tin brackets. I bent them down a bit so the card was held in more secure and all my problems were gone! I really thought it was a software problem. It really still doesn't make sense because I had the problem with or without a sim card in it. But, who cares, now it works! God is good!
I saw this thread and its the same problem i was having, read through it and saw the post about bending the sim card holders down a bit and it actually worked, thanks for the idea
Hi I did the same thing. It worked for a while but started again. After opening the phone a hundred times, flashing a hundreds radios etc what i did and worked was clean the sim card with an eraser. Trust me, u will not get no gsn again and always give u a signal.
I have similar symptoms, although the major difference is that the device crashes and does a hard reset by itself.
Still, I'll try bending the SIM holders; there's nothing to loose at that stage...
Hi all,
Just got home, looked at my mobile and it said there was no signal - so I turned it off and back on again, then it said there was no SIM inserted. Keep restarting the phone, keeps saying the same thing. Why?!
Am going to try it in my old SE K850i to see if it's the SIM card or the phone at fault.
In the mean time, does anyone else know of this fault and how to fix..?
I didn't the drop the phone or anything, it was just in my pocket, on it's own - like it always is!
Cheers
Tried it in my K850, works fine. Please someone help
yeah i usually dont put the sim card all the way in but slightly in and it works
I've re-opened this thread due to me misreading....DOH! Apologies (Mental note to one self.......follow own advice and read before posting).

you could try to clean the contacts on the sim card connector of the phone with a q-tip, and see if that solves the problem.
also check if any of those contacts appears to be bent or something, and so doesn't make a connection with the card.
Everytime I open the back up to remove the SD card, I get the SIM card missing bit even though I have not touched it! My HD is only 3 months old and it has done this from the start. I just have to remove it a bit - shove it back in and the phone accepts it is there. Annoying but not enough for me to send it back.
hmm, maybe try to make the sim a bit thicker so it doesnt move around (it shouldn't move by removing the back cover, but it seems to happen on your phone / sim combination.
try putting a thin piece of paper on top of the sim (not the contacts side, but the side facing to the battery cover)
maybe that prevents this problem?
Missing simcard
I have the same problem with my simcard. Though something strange happens when the phone is off for more then 10min, it works fine and notices there is a simcard for like 30 sec after which the error pops-up again. I have tried all of the above things, my simcard works fine in my other phone, adding some paper to thicken it doesn't work either
Anyone who could help me with this?
P.S. sorry for the bad english
As in post 7# written, put some papersheet in the simholder above your simcard to increase the contactpreasure. This surely helps.
Tis trick is also useful for all dualsim users who thik the dualsimadapter does not work in their device (but after using this trick get astonished!)
for Thysiey:
Try to switch to Gsm mode to test . Maybe you have bad umts signal? Happens at other places too, or only at one place?
Got the same issue here...
I cannot move the SIM because it is being hold in place by the battery. (to little room)
Adding a piece did not work either.
Anyone got another solution?
anyone? My mothers HD just got this problem now. She has a new phone and for the contract renewal she had to read the backside of the sim. The phone all of a sudden didn't recognizes the simcard anymore.. I tried a few other simcards but it won't read it anymore.
My plan was to sell the old phone but now it's almost worthless just a shame it is still a great phone to operate.. handy with the navigation and all
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.
Sent from my GT-I9100 using xda premium
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.
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?

Facing the problem of no service and no sim card detected on my v20 after a reboot or randomly ,i ve tried every thing and found out that the problem is coming from the sim card reader ,there is a space left between the sim card and the reader causing the problem ,the fix is to full the space with a small paper or something to force the sim card into the reader
I know this is a necro post, but I wanted to confirm that this DOES indeed work. I got a second hand V20 from eBay today and couldn't get the thing to recognize the SIM Verizon was giving me at all. Gotta go back tomorrow to have them activate it now that I know this trick works on this phone!!

I ended up sending the phone back for exchange, after a small 1" drop the SIM was dislodged and the adapter broke and got a new one which didn't have the issue, so I unfortunately don't have any pictures. The best way however to place it is to ensure that it is directly over the SIM card and goes into the slot with your SIM, it should be providing some pressure on the back of the SIM to push it into the slot firmly, but not bulge the MicroSD adapter's metal too much, if you've done that, a fall may just break your SIM reader.
