Galaxy S4 - often no sim detected - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

I have Galaxy S4 and It's often occurs to have this message "Error SIM Card Removed - Unable to detect your SIM card".
Now I restored phone to factory reset and I replaced sim card with new one.
Today I replaced sim card slot with new one but issue always is here!

Does pressing on the sim card slot or sim card connection make a difference?
Was the phone dropped at any time? It's possible that something is wrong with the logic board.

Phone sometimes was dropped.
Do you where can I have new logic board at good price in reasonable time?
Thanks

I'm not sure that dropping it would affect just the logic board.
I'm not sure where you are located but you could try and find a used s4 with a broken screen and working motherboard. Swapping the motherboard is pretty easy. If you want to buy from an online seller, you could try eBay or Aliexpress.

X10 Sim Slot Broken After micro sim adapter stuck?

this is what happened. the micro sim adapter got stuck, and i tried my best to pull it back out extremely gently. after pulling it back out, i tried to start it with no sim card but it didnt start.
i took another full size sim, slid it in. it was extremely tight for whatever reason, but anyways after successful insert remove, its now a bit smoother. the problem now is, regardless if i have a sim card in there or not, it still tells me there is no sim card in the slot.
what do u guys think? did i break a sim card pin? i dont have a torx screw driver to check unfortunately...

[Q] S4 unlocked: reads original SIM but suddenly No Sim Card Error on new SIM

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.

SGH i337M suddenly doesn't read SIM and has no popups.

So I recently sold my SGH i337m and the customer has been messaging me telling me that absolutely nothing happens when he inserts his SIM card. No popup saying no sim detected, nothing. When he goes to settings > more networks > mobile networks there's a pop-up that asks him to "insert sim card", and that's about it.
I know for a fact I sold him the phone WORKING as I made sure multiple times to test the phone with my SIM card and everything worked before I sold it to him.
I've been troubleshooting with him but unfortunately I have not come to a solution yet.
Things I have tried:
Remove battery & SIM then put back in
Reboot in safe mode
Wipe cache in recovery mode menu
Wipe data/factory reset in recovery mode menu
Insert another person's SIM (still no pop up, even when he uses a SIM from a locked company, it doesn't even ask for the unlock pin)
I'm hoping some of you guys have a solution because I've been looking all over the internet and no solutions have worked thus far.
Thanks in advance!
Hardware failure. The SIM card tray needs to be replaced. The part is inexpensive ($10), and it's easy to replace, so long as the person doing the work remembers to remove the foam pad on the original tray and place it on the new one.

Hey, I contacted a local shop about repairing the sim card tray and they told me it would cost $90 and that it was a 50/50 chance that it would work and is very risky due to having to "replace the I/C on the motherboard". I looked up SIM card trays online and the piece is $5. Are these guys bull****ting me? Could I replace the sim card tray myself with ease? I'm kind of confused. Thanks in advance.
Shortly after I had gotten my S4, the phone suddenly lost the ability to read a SIM card for this very reason. After purchasing a SIM tray off Amazon, I took the back off the S4 and swapped trays. The nice thing about the S4 is that it's easy to get into with a screwdriver. The place wanting to charge you $90 is charging for labor. Not bulls#!^, but pricey when you can do it yourself. I did it, at a cost of about $10 and 15 minutes of my time, and so can you.

Indeed its bullcrarp to charge so much. Do it yourself, order from Amazon or wherever it is fastest to you. China to US can be couple of weeks atleast.. takes 10 min max.

I9515 won't recognize external SD card

Hello community!
I have the following problem with my S4 VE: It just won't accept my SD card anymore. My desktop PC reads it well, and so do other phones (tried it on a Galaxy S5). To be sure, i formatted the card again, no change. So I started to look for other issues, starting with software. I wiped my device and even flashed a new ROM, with no effect.
So I bought another card reader and installed it. But it just won't recognize it!
What other components could be involved? Keep in mind that only the SD card doesn't work, SIM does, although it occasionally gets "removed".
My next step would be to bathe the entire mainboard in isopropyl so it gets cleaned thoroughly. If that doesn't help, I'll have to buy a phone with a broken display and use its parts.
The SIM card removing itself is a classic indicator of a motherboard failure, so I wouldn't even bother with the isopropyl bath and head straight to buying the phone with the broken display and using its parts.
Just be sure the broken phone is the same model number as your failing device.
Thanks! Seemed like it. Is this a typical issue of the Galaxy S4?
I went for a I9505 instead of the 9515 so I could have decent customization options, starting with Custom ROMs as the display and touchscreen module (not controller) are the same. Works like a charm!
Smart move going with an I9505.
That problem isn't all that common compared to the other SIM card issue, where the SIM card tray itself fails and not the motherboard (characterized by the SIM card not being recognized when you next reboot rather than a spontaneous removal of the card), but it does happen more than it should.

I have an issue with my fiancée s8 plus

My fiancée s8 plus her SIM card got stuck in side the window card hole she used a pin to get it out in the process she tells me her SIM card tray got bent and the SIM card won’t read at all.
She took it to sprint they said it’s broken the unit and they did zero trouble shooting.
Before I order her a new SIM card tray to see if it works what can be done ?
Is the SIM card tray the problem ?

I've had all kinds of issues with the Sim tray on this device. I've replace mine several times. If it's needed up there's a chance. But no one can say yes or no without physically trying what your doing.
