G920I - No SIM Found - Galaxy S6 Q&A, Help & Troubleshooting

Hi guys,
So the other day, phone was working fine. All of a sudden, it comes up saying 'No SIM Found'. The phone is pristine, have never dropped it, not a scratch on it. Have had the SIM replaced, no dice, works fine in my Note 4 though... Also tried the whole 'jam a little bit of cardboard in' caper, in case the SIM wasn't making contact with connectors. Have flashed stock firmware on that too, nothing...
I've read a little on region locking and the like but it doesn't seem to be the case - though I'd love to hear if anyone has a potential fix associated with this so I can try it.
Anyway, long story short, has anyone come across this and has anyone fixed it? I took it to Samsung and they say that they have to replace the mainboard of the phone...
Thanks in advance guys.

Anyone?

SIMs can suddenly fail. Have you tried getting a new one?

Try installing a custom rom. Your only option left without sending it to samsung

Did you found any solution to this?

Hi,
I am wondering if there ever was resolution to this issue. I am running into same exact problem and tried most of general items, except re/soldering the sim reader again

I took it to authorised Samsung repair shop in Croatia for sim reader replacement, and they replaced whole motherboard in factory warranty, even thou I told them I bought the phone over ads and have no warranty.

SIM Problem - PLEASE NEED HELP

Hi,
Suddenly out of the blue my Touch-Cruise decided it does not find the uSIM card anymore.
tried anything i could think of:
tried the uSIM on another phone - ok
tried another uSIM on my Touch-Cruise - no SIM was found.
tried reflashing the ROMs (original ROMs - WM6 and afterwards the WM6.1 versions) --> nothing still not SIM is found
Has anyone else ever encoutered such a problem - it just happend with NO apparent reason one second it seems find the next i suddenly see the the device shows NO-SIM.
Please if anyone has any idea.......
Looks like hardware error...
Are the SIM contacts (the little metal prongs where the SIM goes) all in the correct place? They could have been damaged.

Yep, my Touch-Cruise is learning that trick too. It drops the phone connection and lately asks me to insert a SIM card. The problem seems to get worse, I think repair is needed. Will let you know how I go.
Repaired within one weak. The repair company reported a "weak signal" (?) and probably inserted new motherboard. But it works well again!
This is what happened with my Nike. It all of a sudden stopped reading any SIM card I put in it.
(Selling for spare parts if anyone is interested).
HTC repaired
My Touch cruise has been repaired and works fine with my SIM-card again!
Same problem happens to many of us... (just check the threads...)
I wonder what's the cause of this problem... since nobody knows and many people have found to replace the motherboard fixes the problem... But this is like buying a new Polaris... But what about if you have no guarranty at all...?
Well.. you can ckeck on my posts to know what I have tried so far in order to solve the problem and nothing still has worked out.
I'm having a wonderfull piece of HW and also my old mobile too... :-(
Regads,
Vissi
My phone had that problem too. just sent the phone in for repair. I will update when it comes back.

"No Sim" ?!?!?!?!?!?!?!?

Hi guys,
using this device for a couple of month now without problems
today when I was driving I guess I pressed something wrong 'cause the phone network settings popped and I accidentally chose the wrong provider and now the phone says there is NO SIM!!!! ahhh
Tried shutting it down, restarting it, taking battery & sim out, resetting the phone for yesterdays settings, resetting it to manufacture settings and nothing helped still a message saying NO SIM
so.......... I got to options either the sim went dead in the middle of the day 'cause I told it to use a different provider then mine or the device is a goner.............
tried installing an old sim (not 3.5G) and it still said NO SIM
what say u ?
oh and pls help me
thanks
have you warranty for your phone? looks like you have hardware failed.
well I think the device is in warranty (two and a half month old) the problem is that it was a prize in a competition in the grand nation of america and we are far away from there.....
could it be malfunctioning in the software ?
I am upgrading the rom now maybe it will reslove itself
well updating the Rom to the latest with WM 6.1 didnt solve my problem
is there anyone here who has a similar problem with this or any of HTC devices (Lost the ability to recognise SIM cards) ??????
I've seen a few posts on this forum, complaining on a SIM troubles. If i remember correctly, the reason has been a bad SIM holder socket or something similar. Try looking for those forum threads for more info.
Anyway, the first thing i would probably try is carefully cleaning the SIM socket contacts as well as the actual SIM card contacts with alcohol or something, just to make sure it isn't just a bad contact.
I have been there. My device has been repaired twice and works fine now. The last repair concerned the socket indeed. Maybe that's your problem as well, so check:
- does your SIM work in another mobile?
- does another SIM work in your TC?
- did you clean, reseat your SIM card, try a few times!?
Good luck!
I've polaris too and i've already replaced the sim socket, which malfunctioned..2 weeks after replacement weird things started to happen. I would loose coverage while having a conversation in a place, where all bars are full. Then, after restarting the phone it would show that no sim is inserted AND here's the funny part, after the next restart, the device would return to normal. I could make calls for another day and then it goes again..Right now a week has gone by while i'm restarting my phone every day. The problem is, that right now i need to restart my phone 3-5 times for it to start working normally again (without saying that no sim is inserted).
I can't work out why would this be happening, because if it would be a bad socket, i couldn't use it again after restart, but i CAN.
Can anyone give me advice? Maybe there's a virus from which you can't recover just by flashing the rom
I had the same issue! Therefore I had the phone 3 times in repair under warranty and the issue wasn't rapaired until the third time! All together the phone was in repair over more than 2 months!
I'm pissed off on this lousy service at HTC!
I'm hoping for you not to have such a misfortune then I...
I had the same problem after dismantling.
For me it was that the SIM cable that is going to the motherboard was way to inward. I just withdraw it a bit and that did the trick.
try to install new radio..
if still doesn't works, maybe ur htc hardware problem
I agree with wakhairul2,
if it's not the Radio Rom (GSM depends from it) so it's the hardware!
if it's the second, this is common, Simcard Holder Flex for the Touch Cruise fails easily! but it's also very easy to find a cheap spare..
Anyway, if you have warranty and is less costly then go there..
Else, for a new Simholder hardware check the ebay, Click here to view
You can find for lower than 15 Euros.
Good luck

Cant connect networks! Help please!

So, bought the phone few days ago, and it arrived today. It seemed to work just right, I dont know who the modded the phone, but he did sim mod on it. After putting sim card to the phone it seemed to work just fine, connected to networks and stuff. So I decided to unlock the bootloader and put cyanogenmod on the phone. It worked fine for few hours but now I lost connection to sim card, and I shut down the phone. Took sim card out and put it back in, it did recognize it, but I couldnt contact to any networks, I tried to swapping to GSM only and stuff, but nothing seemed to help. I tried re-flashing CM, but it really didnt help. When I changed the connection type to GSM, it connected to the network for few seconds and then disconnected again. Im gonna try flashing stock rom on but seems like there is something wrong with the phone. Has anyone else had the same problem?
E: Couldnt flash stock rom on the phone using MIUI now and constantly getting messages for "SIM card removed"
So seems like problem is in the sim card holder.
Case of bad luck/coincidence.
Try applying pressure to the SIM (you can remove the back). This way you can find out if it's the holder. I had also had this problem. Not sure if it's a type of holder or just a bad mod. But Cornholio fixed it for me. Contact him, maybe it can be fixed easily. I just sent him my phone since I also had a Photon who needed a new mod.

Probably trying to get the seller to refund to me, seems like he had same problems that I just got but he didnt tell me first, but started to tell me that he had just the same problems earlier. Well, I really wouldnt like to open the phone before I can see what he thinks about the refund.

No need to open the back. Get a very thin knife or something like that. Pry it between the cover and the SIM. it will apply enough pressure to see if that's the problem.

[Q] No Service following Screen Replacement

Hello,
I've just replaced the screen on my Nexus 5 myself, however having searched through this forum for an answer to my problem I'm left kicking myself and wish I'd just sent it to LG as per many recommendations.
The replacement seems to have been quite successful, everything works, apart from I now have 'No Service'. I've removed and inserted the SIM and the phone recognises that a SIM card has been inserted but will only allow Emergency Calls to be made.
Its all been to bits again and put on to the old screen, the problem remains. Very frustrating.
I don't suppose anyone might be able to help me diagnose the problem?
Thanks,
Will
You probably damaged a ribbon or soemthing, the only thing I would suggest is running a full restore by flashing the stock google image and seeing if that helps otherwise take it to an aftermarket repairer
Sounds like it'll have to go to LG anyway then sadly.

[Q] [HELP-Stock ROM] Google Nexus 5 cell radio off. Cannot Make Calls, SMS, or Data.

Hi guys,
I've been a lurker on XDA for quite some time, and I just want to say, I absolutely love you guys. You're all very helpful and so knowledgeable. I can finally say I have an issue, I'm hoping is a software issue only, that I need help with.
Last week I was running Stock Rom Lollipop 5.0.1 on my Google Nexus 5 and now I cannot get a GSM signal AT ALL. No Calls, No SMS, and No Data. The same SIM card can work just fine on my unlocked Nokia Lumia 635. I am long past my RMA. What can I do to try getting the GSM to work and TURN ON MY GSM RADIO? I'm sure if the radio turns on, everything else should work as well.
Brief History: Phone has been dropped on cement before and got Screen replaced. My internal speaker got loose and I just got it readjusted by a nice technician near where I live. I've survived with this phone from Day 1 until now with some cosmetic wear-and-tear, but it was only from last week before I left work, AFTER I UNPLUGGED MY PHONE FROM THE WALL SOCKET that the GSM signal just dropped.... permanently. And what I mean by this is, the "radio" is off permanently (I cannot turn it on even with the option in *#*#INFO#*#* with SIM card inserted) even after reboot, airplane mode on/off, and APN setup (which can never be saved and hangs when selecting automatically 'detecting'). Note: The Phone can charge just fine and connect to the computer perfectly fine as well (in case you guys think it may be related to the microUSB port assembly). I have been taking out my SIM frequently, so I'm still not 100% sure if it is or is not my SIM Card Reader pins that have an issue.
I have fastbooted several factory images on this device many times from the Google factory images repository, mainly going back and forth between 4.4.4 and 5.0.1 which I believe are the best releases so far IMO. Even after installing the factory roms on this phone, (no root) I still get no signal no matter what I do. When I remove my sim card tray from the phone, I get "No SIM Card". When I put it back in, I get that message going away, which gives me the impression the SIM card reader is fine. My technician took a look at the entire phone hardware and said he didn't find ANYTHING strange. He tried using a known working back-cover with antennas to debug the issue but that didn't help. I don't remember what he said about the sim card reader, but I think that was also fine (will double check next week). When I got the phone back from the tech, he just told me that there are no "hardware" issues he knows of, and so this must be "software".
Any leads you can give me? I'm pretty tech savvy, and do understand things like partitions, fastboot, adb, etc, so any solution, even abstract, I'm willing to try. Google reps were pretty clueless on helping me out here, so I'm looking for some support, please!
I've also heard that this issue is not uncommon on Nexus 5. Is this true? How many users have been having this issue? I thought Nexus 5 should have been built great to last a long time... guess I was wrong.

Same situation on my Nexus 5 that started a few days ago. Thought it had something to do with the 5.1 Lollipop update and saw some users were having similar problems. Tried flashing different radios/basebands/roms/kernels to no avail. Currently running 5.0.1
Hoping it is not a hardware problem, going to take it to a local technician today. Also beyond warranty. Everything else works fine. Has always been in a hard case but dropped a couple of times with no prior issues. Any insight?
5.1 is the best software. If it's not hardware all I can suggest is a full factory reset. My SD card was not acessable and pple said try this and that command. No luck. Did a factory reset and got the SD back Oh and screen shots which had gone as well.
