I have started having SIM card issues about a year ago, and it started with their new SIM cards. They advised me to get a new one, so I could use tethering. Since I have, I kept randomly getting "No SIM detected, please restart to detect your SIM" randomly, and it has been really annoying. I have replaced the SIM slot, and cleaned it multiple times, sometimes it works afterwards sometimes not. It seems to me like this would be a hardware issue, but could it possibly be software?
I notice on the different SIM slots I have bought, there are different revision numbers. What is the latest revision, that has the best contacts? Taking one apart, I noticed the contacts are crap. VERY small, that barely make contact. I was thinking of de-soldering the crappy SIM tray, and finding an SMD that has ball-bearing contacts, has anyone ever done this?
Last month, I accidentally left my SGH-M919 in my pocket and the motherboard was fried when it got put in the wash. I tried resurrecting it with the RIFF, but the eMMC was dead. Anyways, I managed to find a new motherboard with a clean IMEI, and got the lowest android version possible (so I could use "CF Auto Root" and "Region Lock Away").
I can insert my SIMple mobile SIM and it detects it, and it detects my old T-Mobile SIMs, but it will not detect my active one. The version I had that partially worked of Android was 4.4.4, this "new" motherboard has 4.3.
Is it possible that, since the board has older baseband, it will not detect new SIMs? I am afraid to upgrade to the latest OTA as then I most likely cannot use "CF Region Lock Away". Can I root it first, then use the latest custom MOD, or must I do the OTA to get the baseband and low-level radio / SIM interface upgraded?
I was told by T-Mobile that this is a known issue on the S4, and should buy a new phone (of course). I haven't the means, and am trying to get this fixed, as it's really annoying. Anyone have this same problem, and have any ideas?
Thanks,

I broke and replaced the screen in my unlocked upgraded flashed-ROM wallaby and the unit now starts up and reports invalid SIM.
Is there any solution or should I re-flash the rom again and see if that works, hope for the best?
Try the SIM in a different (unlocked) phone, to make sure the SIM isn't fried. If the SIM is fried, you can get a new one from your provider. SIMs do get fried sometimes -- it happened to me a couple months back. Fortunately my provider (Cingular) has a shop just down the road from me, and they burned a new SIM in 5 minutes.
I apologise, I should have said
Sorry, I should have said, it does work in another machine and as I said, it did work immediately I used the xda flashing process to upgrade the ROM in this very unit before I dropped it.
Everything else in the new ROM seems to work which makes it infuriating that it wont recognise the SIM. I even tried calling T-Mobile and asking them if they could see the SIM on their network and they couldn't.
(I even have one of those SIM copying devices they send you free for some unknown reason when they want you to upgrade your service to some kind of higher level SIM card. I was wondering if I should try to use it again but as mine does work, this, like the whole copying device, seemed a bit academic)
I just bought a used G2 for my son to be used as a wifi phone. I successively rooted and have Andromadus jellybelly on there. The phone was sold as unable to read the sim card, and I am wondering if there is a method to figure out if the reason is software related vs physical/hardware related? Any suggestions on what to try?
If it didn't work stock and still won't work after tooted and custom rom I doubt its software/firmware
So that leaves hardware, it seems the sim tray comes detatched from logic board on some of these, you can try and resolder the tray or pick up a new one. Possibly something else but it will be hard to determin other than trial and error

Look at the contact pins in the sim slot, make sure that they're straight and "up". If there are any that are bent over or not sticking up properly, those aren't making contact and therefore the sim won't work.
I have root, thats it, i get NO SIM in the notifications and have no data. Every now and then I would be able to restart to fix it,but now it seems its working either. ICCID is unknown in About phone. Everything else seems alright.
This is almost a brand new phone, only rooted. Had no new ROM installed on it. I restored it to the very first backup i made after rooting, same issue. I have a pending 4.3 update,which I have not updated yet.
Any idea what's going on ?
No one?

My son was having issues with his HTC One's SIM card. Data was sporadic, no LTE, and he would get no SIM card errors. We took it in to the Sprint repair center in the area and they first tried blowing out the SIM card slot but ended up putting in a new SIM card which fixed the problem.
Hopefully the person who looks at your phone is competent as we had to make a few trips as we were told at one point that we didn't even need a SIM card since we were not going Global - this older guy was wrong. We ended up having this young woman take a look at it and she swapped it out ASAP and we were good. I'm going on a bit but I was somewhat floored that their repair tech gave info that was just wrong. I've had to go back a few other times (for other reasons) and I avoid that dude at all costs (straight to the young woman).
Unfortuantely, on note 2 the sim card is not even accesible. Its buried/sealed inside, unless sprint techs have a way to access it.I am surprised this is such a low occuring issue, that no one in this forum has this.
Same thing
Same thing happened to me 2 weeks ago, i had to order a new card

The "techs" there are a joke. The only people who can REALLY help are devs who they probably keep locked away in a safe house abroad. There hasn't been a single time when a phone carrier tech was remotely helpful for me.
And the SIM is on the same module as the SD card. IIRC they can swap out this entire module. How will they replicate the same iccid onto the new one? No clue. If they replaced it and your issue was fixed though they did it somehow. Or else your authentications would be all messed up (meid> mdn>min>HDR AN>profile 0 and 1>iccid...probably more I'm forgetting)

I lost my P3XL on a accident and recently, after 8 weeks, I got it back when someone found it laying in a Bush near the place where the accident happened - it's summer time fortunately and except a little dirt the device is fine, everything is working and no water damage!
The person who found it saw the emergency information and brought it to my address, big luck!!! 8 weeks outside, 3 times heavy rain, the fabric case it had was moulding but the device itself is just fine, crazy!
When the device was lost I locked the Sim inside the device via the provider's homepage, so I got a replacement SIM a little while later... The usual stuff what people do in situations like this
Now the problem I have is the new Sim, the provider told me that it's a new generation of Sim and the module on the Sim looks different, it's silver and the module (chip on the Sim card) has a different setup, the lines are very different! According to the provider (O2 germany) the Sim uses less electricity than the previous generation and unfortunately it's not detected by my device at all, no reaction, nothing, like there's no Sim inside...
- I reseted the network settings
- factory reseted
- upgrade to Android R
Nothing helped, however the Sim is detected immediately by my 3 other Android devices and the Pixel detects all 4 Sim cards I tried, it's only the one Sim I have a contract with that makes issues. The provider sent a new replacement Sim which looks exactly like the previous one and is also not detected.
I don't think it's in relation to the weeks it was laying outside as it's only this specific Sim card, again, the card works in all others device and the Pixel 3 XL detects all other Sim cards I tried...
I luckily found a provider that offers eSim so I could register at least the virtual Sim to make calls and have data (I wanted something that is prepaid and where I can leave every month and is not to expensive, it's 'simquadrat' now)...
It's like the hardware is not capable to detect certain Sim cards with a specific module (chip on the Sim).
Any ideas, someone else with this specific issue?
Interesting problem. Do you think the provider has blacklisted your device on their network due to the supposed loss of the phone? The sim needs to detect the IMEI and perhaps that's become the issue?
I updated my pixel to A13 last week and on restart was prompted to enter my sim lock pin, all seemed well but it wasn't. Somehow, my sim stopped working although my phone recognises it. Could it be the update broke my sim or is it just coincidence?

If you've tried the SIM Card in another phone & it's still not working, my guess is that it's a coincidence.
I'd reach out to your service provider for a new SIM Card, especially if the one you're using is more than a year old, it may not be able to fully take advantage of any/all of the newer/5G Bands on your network.
I know that this is recommended for T-Mobile US.

I did try my sim in my old Samsung S7 and it didn't work. It just seemed strange that it broke after updating my phone but yes, it most probably is a coincidence

FWIW, I've run several betas of 12 & pre & post stable 13,including stable 13 & haven't had any connectivity issues. The SIM is new, used the one that came with the phone.
Since it's not working on another device, I'd chalk it up to pure coincidence.
Before responding, I did a bit of Google-Fu, as I'm sure you did as well & didn't see anything pointing to the update causing the problem.
Now, wireless charging, especially with Google's 2nd Gen charger, that's another story.......
