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?

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
As the title suggests, my phone is coming up with "No SIM Inserted" warnings, and forces me to restart two or three times to get the problem to go away. This happens pretty much daily, at the minimum.
Restarting takes an annoying amount of battery and time, so it's a bit of a pain. The SIM eventually works, but it's not a good sign.
Since the card eventually works, I'd imagine that this is some sort of Firmware issue? My internet is horrible, so downloading it from sammobile would take forever. So I thought that I'd come get your guys opinion on it first on whether it's a hardware issue, or a software issue.. I've noticed a lot of other phones (such as the S4) having this issue, and I'm wondering if anyone has had any experience on fixing it?
It's unrooted so it's still under warranty.

First thing I would try is clean the sim card then factory reset with the sim inserted. I had to do this with mine (once) but thought it was just a glitch so never posted about it. After that I'd try another sim to test the handset or replace the sim card if it was the same.
Had this problem in one of my older phones, can't remember which.
At some point your SIM will stop working altogether and reboots just won't fix it anymore.
I contacted my provider and asked for a new SIM and that solved my problem.
I think it's worth getting a new SIM, or at least trying with a different one.

I'm not sure how I'd clean it, exactly. So I just sorta blew on it, and the tray. If it happens again I'll probably just get a new SIMcard.

The SIM is barely a year old, so it's a bit of a pain if I'll have to get a new one. However, it'd cost me nothing to get a new one, anyway.
Thanks a lot for your input. It only started happening about a week or two ago, so it probably is the SIM.

When I had that issue, it was with a few days old SIM, sometimes they're just defective. I know what you mean about the hassle though.

Clean the SIM with a pencil eraser.
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.

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.
Hi friends,
I've just upgraded my Sony X Compact (F5321) to latest Android 8.0.0, version 34.4.A.2.85, via OTA, and SIM card is not detected anymore. I've tried to restart the phone several times, also tried to stop "Xperia Assist" app (it was not stopped). I have removed the SIM card and re-inserted, . I have also tried Repair with Xperia Companion and Factory Reset as well. Nothing worked: SIM card is still not detected. Did anybodu experience this? anybody solved it?. Thanks a lot in advance for an urgent reply. I work with the phone
Have you tried a different SIM card in the phone? Just trying to rule out a defect in the card itself.

Dear,
I have tried the obvious checks: I tested my SIM card in another phone (it worked). I have tried another SIM card in my phone (it didn´t work).
Thanks anyway
Yes, it really does sound like a hardware failure, perhaps at the point of contact with the SIM card metallic strips. It might be possible (but risky) to apply a thin shim to the side of the SIM opposite the contacts, BUT you risk damaging the delicate tray mechanism. There could of course also be a component-level failure. I have had my XXC suddenly stop recognizing my SD card, but it was only a transient problem, and did not recur.
EDIT: If you decide you want to try the shim, best to apply an exact-sized piece of paper to the all-plastic side of the SIM itself. If that doesn't work, you could apply a second layer, but that would almost certainly be the limit.
you can try to get to the previous version of oreo

yes, but I would like Sony to do the downgrade, if It unlock bootloader, I will void the warranty. Anyway, I have tried, and I had issues with S1 fastboot driver to be installed in Windows 7. if I don´t get an "official" solution from Sony, I will go back to that option.

do you have a have a video link that explains that procedure? thanks in advance
No video, but by applying a thin shim to the backside of the SIM card you would in effect be pushing the card just slightly closer to the points of contact within the phone. However, seeing as a number of people have experienced this problem suddenly upon upgrading the firmware to ...85, I am now inclined to believe there is a software problem in certain versions of the firmware. I guess if it were me, I would try using flashtool to install the ...70 version of the firmware first and see if that solves the problem.
You don't need to unlock bootloader to perform a software downgrade.
Bought a second Xperia X Compact for a family member, and it has the same problem as yours had. In my case I did reflash with a slightly earlier firmware (...70 rather than ...85), and the problem persists. I also tried using a single paper's thickness as a shim, applied to the back of the Sim card. Nothing has worked, so the phone is being returned. I wouldn't be surprised if the problem is a bad batch of phones, or perhaps a flaw in the design which makes this problem more common than it should be.
