Samsung Galaxy S Captivate not recognizing sim card.

i have torch v1.5 on my phone. when i took my sim out, put a friends in so she could use it, then put mine back in, it didnt recognize my sim. i cant access the APN settings to change those back to rogers, because it says "insert sim card to access network services". can someone please help me with this as i NEED my phone for this weekend.
Cheers
Get a new sim card?
Does your sim card work in a different phone?
That happened to me once. I had to return the phone. I was unable to get it to recognize the sim card.
Different rom didn't help either. Even when I flashed back to stock... no sim. It was a refurb so a new one was easy to get.
Hope you get it worked out.

This happened to me earlier this week. Flash to stock and then back to the rom worked for me

Clean contacts on sim card. Factory reset. If that doesn't work call Rogers for replacement.
No warranty you can replace the simcard slot its a daughter card I think you can order from globalpartsdirect
I have the exact same problem. Again it happened with a warranty phone I just received today. It occurred while trying to root the phone. The SIM card from my wife's iPhone does not work in my phone either. However, my SIM works in her phone. I've tried just about everything I can think of at this point other than running Kies (my next try).
BTW,
Unlike my original Captivate, this one came to me with Froyo already installed.
Under Menu /Settings / About phone /Status /Network what does it say ??
If it says "Unknown" you could try just flashing ur modem again.
I am having the exact same issue with a refurbished phone from AT&T and insurance gone im out of luck unless there is a easy solution.
Hello Everyone, So this is my situation so far:
I have a Samsung Captivate with unbrickable mod added. I flashed with Heindall to 2.2 froyo on linux. The SIM card is not recognized. I have triend 2.1 and 2.2 and 2.3 one clicks in windwons with no luck. I tried to mess with IMEI and elfs file. Results were that the lines i was suppose to change on nv.bin did not exist (no lines in file i was attempting to correct). So at this point and time can i conclude this is absolutely not a software issue? Problem two is if this is a hardware issue and not a software issue. Where do i begin? how much is the price for replacement? How hard is it to do? I have tried flashing with everything off the phone (sim and sd) Im a bit lost at this point. Any help would be great.
Update: Spoke with Adam and he says its not a software issue. I also spoke with the guys who did the soldering and said the issue is not coming from the soldering. I am thinking maybe when the phone was taken apart something got loose? Any thoughts anyone?

[Q] Droid Bionic: SIM card is from an unknown source

I got my Bionic in the mail from an online reseller yesterday and, so far, have been unable to get past the Welcome to Droid Bionic screen. When I originally took my Bionic out of the UPS box, I didn't see that there was a small SD card burried under the packaging, so I went to VZW store to get a fresh one. They were able to deactivate the old SIM card and activate another one and popped it in. Unfortunately, the new card is not recognized by the phone. They tried a second card and it does the same. The phone says "SIM card is from an unknown source." They VZW techs told me it was the phone and I needed to return it.
When I got home after spending hours at the VZW store, I found the original SIM card in the UPS box and popped it in. The phone recognizes this original card and tries to go through activation but, naturally, fails since its number was disabled at the VZW store. I'm wondering if it's worth it to try to go back to VZW again to try another card now that the phone has shown that it is capable of recognizing SIM cards or just scrap it and send the phone back for a replacement. Maybe there is a trick I can do to get things working again with the original card?
Any suggestions or past experiences with this would be helpful.
Thanks.

Bumping because I've had a similar issue. Must suck not being able to use the phone
perhaps you could name the online resaler as to avoid headaches for other consumers
i had similar problem. had to go get new sim card. then it wouldnt activate. the verizon store people told me it was the phone and to send it back. i told them i wanted a second opinion and made them call tech support. while i was waiting for them to ansewer the phone. i did a factory reset. it booted and activated no problem then.
mine was from letstalk.com. but i think it was my fault i needed a new sim
The reseller was LetsTalk.com but I don't think that it is their fault. I'd like to say that there is just something going on with the card registrations. The phone has proven that it's able to recognize SIM cards. I just need it to recognize an active one now.
I will try a factory reset once I get back to the VZW store and get an active SIM card to pop in.
UPDATE
I was able to get the phone to recognize another SIM card after having registered the original one with the device. VZW activated a new card and got it up and working.
If anyone else is having this problem, I would suggest going through the motions of activation with the original card (assuming its not recognized as being from an unknown source) and then having VZW activate a fresh SIM.
Thanks for the input.

Kernel Panic Upload Mode

Hello,
My galaxy s3 LTE keeps randomly loosing reception and on a rest goes into kernel panic upload mode. It is rooted and has TWRP, it is currently running the sentinel rom. I feel as though it may be something with the sim card slot. I cut a normal sized sim to fit in prior to getting a proper micro sim. If I reset it goes into the panic mode and will stay there until I boot without a sim card, shutdown and restart with the sim card in. I have formatted the data and system partitions. It only happens maybe once a week, which I dont mind. Has anyone else had this issue?
Thanks
James

Hi James,i have the i9300 but i guess this is the same issue.
Mine when i had my homemade sim,kept on loosing signal sometimes and showed the message:
"Sim card has been removed."
And forced me to reboot my phone! -.^
Anyway,it hasn't shown this message to me since i got a proper sim card and i suggest you do the same. (it costs around 5 euros here,kinda cheap)
I have a proper micro sim now. It seems to have the same problem. Much less often than when I had my home cut sim

Note 5 Sim Card Removed errors! Help!

Hi, I bought a used unlocked T-Mobile Note 5 a few months ago and for the first month or so it worked great. Then I started getting this Sim Card Removed error occasionally. After a restart it would be fine for a while and then pop up again. Now it's basically constant, several times per hour I get this error and have to restart the phone, sometimes even immediately after a restart it pops up again, other times it'll go a few hours without popping up. I tried a fix I found online of taping the Sim Card into the Sim tray so it can't move, and it didn't help at all. The Sim card works just fine in my Nexus 6p, so it's not a sim card issue I don't think. Any help would be appreciated!!
Anyone got any ideas on this issue? I got a new SIM card and it's still happening.

My G6 Shows 'Corrupt SD Card' Error but Fails to Format it

My G6 says that my SD card is corrupted, so when I go to format it the percentage completed immediately shows 20% then, after about 10 seconds, the formatting screen closes before it completes the format, and the whole time it shows that it's formatting it is always at 20%. Then my G6 acts as though there isn't an SD card in the phone, it only shows up again after I power cycle the phone. I have tested multiple MicroSD cards on this G6 and the same thing happens for every single one I tested, but I happen to have (limited) access to my mom's G6 and when I tested the same cards on her phone it says the SD card is corrupted, but successfully formats it and mounts it.
The MicroSD card that I would like to use with my phone is a 200gb SanDisk card.
Thanks in advance.
Update 7/2/2018
Hey, Can it be read/formatted in a computer with your sd adapter like a flash drive? if it can try reformatting it there then see if your device can recognize it. if it can't or it says corrupt / needs to be formatted and craps out... it's your SD card. it is the same one I had (probably..with red lettering on it?) That's the bad news, the good news is you can still go online and register it with SanDisk and they will send you a new one for free (cost of shipping to them the corrupt one, you have to pay.) But they will send a replacement, I think it took about 2 weeks to get one back.
Take care.

I can plug it into a computer and format it successfully, it works in literally every other device that I've tested it in, including my mom's G6. That's why I have a feeling that the problem is being caused by some sort of issue with my G6. I have tried factory resetting my G6 two times already and it failed to fix the issue. I want to root my phone, but my software version is H87211h, and the method mentioned here has (as far as I know) only been tested on devices running H87211g.
Hello there. I have same problem with my LG G6, It shows every SD Card as corrupt and tap to fix. when i try to fix and format it get stuck on 20% its been more then two months and i am unable to use the memory card on it..
There is nothing wrong with Memory cards , it is the problem with the LG G6 either it is software issue or may be due to the fact that i have changed the Sim Tray as my sim tray was broken... The Network sim card work fine only problem is the Sd Card.... If any one have the sim issue or any solution .. Please share.. Thanks

Same thing happened to me, my SIM Tray broke and I bought a replacement from Amazon and that's when the issue appeared.
I updated my G6 to Oreo and now it shows what command is causing the formatting app to crash. I've attached a screenshot.
OK, so with the new info (sd tray breaking) I think what happens is when the SD tray is breaking, it's getting caught up on the little pins inside that contact the SD card and bending them a bit, and then that pin or pins are screwed up so it can't read the SD, and because it detects that there is one in there, begins to format and go thru the sectors when it gets to the messed up pin it craps out because it's not reading anything so it's saying the card is corrupt at that point. You have to send it into LG for a warranty repair. I had to do this too. go on the website, register your device, tell them the SD tray broke inside and it won't read the SD card or the SIM, and you will get a repair number within 24 hrs or so. Send in the device and you will get it back about a week turnaround time.
Good luck.
Most every time I've had this issue has been after an update or switching ROMs or kernel update and usually the issue is the kernel.
So basically speaking if you have an SD card corruption after any of these particular events reflash your kernel first.
I just bought a new Samsung 256GB microSD. I copied everything from my old card onto my PC, then onto my new card, and then put the new card in my phone. Android says it's corrupt and needs formatted. I try to format it and it always gives an error saying the command failed. Put the card back in my PC (which now can't use the card either) and performed a format (without the Fast option). Android still says it's corrupt and always fails to format it. So I put my old card back in the phone, and now it says it's corrupt too...
I had noticed that when I first opened the tray door it was being janky and wouldn't come out but a half inch. After reading this and getting the error for my old card too I decided to take the tray all the way out. Wasn't easy getting it out and now it's broken. Or already was broken. I tried cutting off the broken part and put the tray back, but now it won't even see a card or my SIM. So I've ordered a new tray. Hopefully that will solve everything... Unless my pins are jacked up as suggested earlier....
Well, got a new sim tray, and now it can read the SIM fine, but every SD card still says corrupt, and it fails to format it each time.
Out of warranty -- I bet the repairs cost half what I paid for the phone (like $200, crazy sale, two years ago). Sigh.
Any other thoughts on this?
The same problem with my lg g6 dual , did you have solution ?
Thanks to everyone pointing out that broken tray that damages the pin's issue. Seems that exactly what happened to the phone I gave my mom. Little to no chance here in South Africa that we could get it repaired for any reasonable price. At least this thread stopped me hunting around for a solution to the "keeps-formatting" but not working issue. Bit of a waste that I bought a new memory card, but not the end of the world. Wasting a few hours on a lost cause is much worst.
So glad I found this...
Unfortunately I already bought a new tray to replace the broken one, but now at least I know not to spend hours and hours on an issue I couldn't possible fix myself...
