Hello
A couple of days ago I took out my sim card, then tried to put back in, but couldn't because there was some resistance, so I applied a little bit of force and put the card back. The force was not that much, I don't think I broke any of the sim pins but seems like I did, because no matter what I do sim is not recognized.
How can I make sure there's a hardware problem without opening the phone?
Same problem here. It appears to be something rellated to the IMEI and now I'm trying to recover it using QPST.

Hi everyone.
I got a Legend yesterday and since I needed to make some backups from my current phone I didn't put the SIM card right away on the Legend.
So I turned it on, did the First Time wizard, installed some apps, browsed the web, applied a system update (not to the operating system, I think it was a radio update or something) and when the backups on the other phone were finished, I slid the SIM card onto its bay, turned the phone on and it still reported that no SIM card was detected.
Restarted. Same thing.
Did a hard reset (factory reset). Same thing.
Am I looking at a defective phone? SIM card with problems? Anything else?
I didn't try any other cards, but will do as soon as I get home.
Thanks in advance.

Hey Mate,
This is a common problem, especially on Vodafone networks... I found this too, it's basically cause the SIM isn't as thick as it should be.
To solve it, rip a piece of paper up to be slightly larger than your SIM, and slide it into the slot before you put in your SIM. Then, pop in your SIM and you're away.
Make sure you leave a bit of the paper poking out so it doesn't get stuck in there.
Thanks owenw.
As silly as it might sound, when I got home I inserted another card from another carrier and it worked. Then I inserted mine and it started to work, so no need for the piece of paper, but very much appreciated.
My wife ATT S4 started to get the message that SIM card was not detected and the phone rebooted automatically after, after dealing with this for a while we took it to the store and nad the SIM card replaced, It work ok for a couple of days and started with the same issue again, we change the SIM card again with same results, so i decided to replace the SIM card holder i ordered the part and replaced it successfully and after a couple of days AGAIN start with the same issue.
The phone is out of warranty and i have no insurance on it, I have not reset the OS yet, any recommendations??
If i replace the motherboard will that fix that issue??
please any feed back will be greatly appreciated
Hi all, I have strange problem with my S4 GT I9505. I read various forums and searched but couldn't find a similar case to this strange problem. I am quite new to android and hope that maybe somebody of you would be able to help me or point me in the right direction to solve the issue below.
Issue
I had the phone unlocked from my provider O2 in UK and moved outside of Europe. My S4 accepted the new SIM card for the first 2 to 3 month. At this time my S4 was unrooted. Out of the blue it started with no sim card error, please reboot when using the new Sim Card.
Here is a list of all changes I done but it didn't help
- unrooted: Factory reset Kitkat, updated to Lollipop
- Rooted the phone as above didn't help, installed various custom ROMS, stock Lollipop, Google play edition. After I flashed the ROM I have for a short time network with the new SIM card but then it starts again with the No Sim Card Error. However, I have no problem with my original O2 SIM card.
- Changed SIM card, checked my new SIM card with other phones and it worked, so it not a fault on the SIM card
- Checked with my provider O2 in UK: phone is unlocked,
- Tried to open Service Menu but none of the codes worked, went to EFS folder/carrier/hidden menu and changed OFF to ON, still could open Service Menu to check if the phone was still blocked etc.
Any guidance how to solve this would be greatly appreciated.
Thanks, Frank
Hardware failure. Replace the sim slot. No messing with software is going to fix that.

Thanks, I will try this next, hopefully this will fit it!
No reason it shouldn't, and it's arguably the easiest hardware fix you can do since the SIM tray isn't soldered to the mainboard. Just keep in mind the following: when you purchase a replacement tray, don't throw out the old one until you peel the foam pad off the top of the connector and attach it to the new tray. That pad prevents the connector from popping off the socket it sits in.

I changed the SIM/SD card holder today, however, I am afraid it didn't take long for the no sim card error to return. Only difference today, it connects to the mobile network again after reboot.
The strange thing is, I don't get the SIM card error when inserting the original 02 Sim card, only when inserting a none 02 card (phone is unlocked)
Would this mean that the motherboard is defect?
Most likely, yes.
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
I just got an Axon 7, and everything seems to be working well. But I set up the "scheduled power on/off" option to shutdown at 3AM and reboot at 5AM, and so far (2 days), the phone has been showing "no sim card" every morning. The first day, a manual reboot detected the sim card. Today, it didn't. After powering down and reseating the sim card, it was detected, but I don't know whether the reboot did the trick or the reseating.
Anyway, does this sound like a hardware or software issue? Anybody else having it?
Happened again this morning. A manual reboot brought it back again. I'm going to disable the 'scheduled reboot' option and see if that 'fixes' it. But it doesn't seem to be a hardware thing, since most of the time, a manual reboot detects the sim. Could it just be done dodgy timing issue in the boot sequence. I'm running the latest B27 US build.

Okay, it's failing hard now. 4 reboots in a row with "no sim card". So I tried the card in my old phone - not detected there either. Can a phone fry a SIM card - because it looks like that's happened.

LG G3 here - half the time after a reboot, it gives me the same SIM card error. After which of course i need to reboot it several times before it will recognize the sim card again.
This looks like a hardware fault, probably a bent pin in the card reader, so i carefully cut off the cover of the reader slot with a dremel + small cutting disc, being very careful to leave the sides of the cover to hold the card in place while it's in - it doesn't seem to be the case, everything looks fine, and from the markings left on the sim card by the pins as you remove/insert it, looks like all the pins are contacting the points on the card itself.
Also very weird that it ONLY happens right after rebooting. The most probable scenario i can think of, is that the card is read on bootup, and not interacted with again during normal usage of the phone...? or maybe a glitch with timestamps? A few times, restoring the backup of EFS partitions "seemed" to fix the problem, but :/
so.... WTF??!?!??!?
Was it a used or new Axon 7?
If used, someone may have had an SD in with the SIM and damaged it.
I was running mine that way but was careful and it survived ok.
Have you tried the SIM in both positions as 1 or 2?
Also ensure it has a correct APN saved against that SIM.
UPDATE: (LG G3) Seems it's a software bug after all. I updated to a newer version of LineageOS, and out of 6 times i just rebooted to test, the "no sim card" problem occured once. So maybe it's not 100% solved, but at least i don't have to futz around for 30-40 minutes to get my phone working again after a reboot.
