I have a Samsung Galaxy A5 2017 SM-A520W, which I recently bootlooped and had to reinstall the firmware using Odin. However, when I restored my nandroid backup, the SIM card refuses to be recognized. It works in my other phone however (which I temporarily switched it while I fixed the samsung). So I tried resetting network settings, clearing the cache and other suggestions, until I finally decided to just factory reset the rom and see if it recognizes it from a clean OS, and it didn't. I can't see any reason why the hardware would be broken, since all I did was take the SIM card out and put it back in.
So then I thought about the firmware. I got it from here, which has a ton of different product codes for different carriers and countries. I'm in Canada on the Fido network, so that's what I chose (FMC). But Fido is owned by Rogers, which is a different product code (RWC)... So I'm wondering if choosing the wrong firmware will actually prevent the SIM card from being recognized? I can't understand why it's not recognizing it. >.<
Any ideas?
Thanks!
Have you checked the APN name and settings?
Hmm, I'm not sure I understand, can you explain further?

I mean the settings for the carrier like mmsproxy and ipv4, etc...
It's a longshot but it's in settings and network settings - mobile data.
I do not know exact english words used... Accesspointname if directly translated.
Describe more about phone behaviour.
Do you get same notifications as when no sim in phone?

Hey folks, i tried searching here for my issue. I found many similar threads, but nothing that solves my issue.
Two days ago i started having issues sending picture messages, today i start losing network signal until it cut out alltogether.
I tried multiple sims from different carriers and got nothing. Ive tried the following:
Factory reset.
Rebooting and reinserting sim
Resetting apn settings, custom apn settings.
I have WiFi, and the symbol says "no service" nothing about emergency calls only.
The new information i have, which i didnt find on other threads here is this; i found a sim card app and tried it, its able to pull my sim card information off the card, (phone number etc.) yet i get no cell service. Any ideas?

Hey @kimsgrim
Hmm so u already did a factory reset? And didn't restore anything before test?
Really stock or u changed anything (Rom or Kernel)?
But ur phone doesn't say "No Simcard found, please insert and reboot" or kind of that?
If no the simcard is fine and the phone also seeing it. The sims u tested where card which definitly work on other phones?
So two things possible in my opinion:
1) System problem: Anything is reset or not working, which should be done with a factory reset or maybe flashing another stock firmware over
2) Hardware defect of antenna. Would be sad, but no other point for be atm.
Much success
CHEERS
Sounds like the sim card reader is messed
it is my uncle's phone
SM-G920F Galaxy S6 (G20FXXU5DQA2)
flashed back to stock and everything is 100% stock but the mobile networks in settings is missing and the sim cards wont work, it detects them being inserted but doesnt seem to connect.
Please help, couldn't find anything
Messing around with mobile data gives "insert sim card"
tried to factory reset from recovery, clearing the cache and reset from the Smart Switch desktop software.
Could possibly be an issue with the sim card slot, does the phone show a valid imei number?

100% hw, faulty SIM reader, cold solder, or something else on motherboard.
Try to ask in Samsung authorised repair center, maybe if you are lucky like me, factory warranty would be accepted.
I just told them I bought the phone second hand and it does not recognize SIM, did not go into details
force stop stuck on s6

The same thing happened to my G920P and I was stressing out looking for a solution. Finally, I figured it out myself.... I used idonne apps unlocking service awhile ago and still had their unlock app installed on my device. After trying repeatedly to no avail to unlock again I finally started looking thru the 3 dot settings and manuvered to the IOT HIDDEN SETTINGS TAB. From there I went to the "test mode menu" setting. Then to HW Test setting, down to #7 NV Rebuild All. Clicked that and let it do it's thing and all settings returned, no more stressing. Hope it works for you.
Alright, so, last weekend I got a new Samsung Galaxy J7 with Android 6.0.1. The first thing I did was rooting it. It was all going fine until I accidentally unticked the "OEM Unlock" option on Developer Mode, so when I rebooted it, it had an FRP Lock.
I used a Latin American firmware to be able to boot it again. At boot, there was this "entel" logo, and this seemed to have changed my IMEI because my phone always said Network Unavailable. I didn't check the IMEI prior to rooting it, but I noticed the printed one and the one shown on the phone weren't the same... but this isn't the real problem.
Originally, the phone was unlocked (no specific carrier/operator holding it), and I somehow "fixed" the Network Unavailable thing by erasing the efs folder on root... well, it was a longer process than just deleting it, I backed up the folder and copied some files (some might know what I'm talking about). After that, the IMEI was the same than the printed one, but, my phone is now network SIM locked!
I have to input a code to unlock it. I did some googling and apparently only the carrier can give it to you, so I tried 3 different carrier SIM cards to see if any of them were the carrier's, but none of them worked as accepted,and I don't know what carrier could it be... I'm even worried it may be a Latin American one (from Chile or Argentina maybe since that's where the firmware used was from) and I won't be able to get it.
I know there are websites to get a code, but I don't want to pay so much and risk getting scammed.
I tried to see if "entel" was a carrier to unlock it, but it didn't help.
Also, when I try to choose a network on Mobile Networks settings, the only available one is AT&T (which I don't use/have a SIM of), but when I accessed their website to unlock, it said my IMEI wasn't registered as theirs apparently.
Then, I also tried using Samsung's Smart Switch application on PC with the Device Initialization option, but when I try to use the firmware from that I get a SW REV. Check Fail.
I might be wrong, but I feel that since messing with the system files/root was what changed it, maybe I can fix it the same way with no unlock code or carrier help.
So, does anyone have advice, or know some other way to reset it? Or do I really have to go get it fixed/unlocked somewhere?

Did you ever get anywhere with this? I am trying to switch carriers from t mobile to boost on the Sm-j700f and I need to unlock it

PROBLEM:
Purchased new sim card with Mint Mobile for Google Pixel 3. Phone is not recognizing SIM card. Google Pixel 3 Forum did not respond. Is there another place to put this question?
DETAILS:
Phone is compatible, sim is functioning and active.
Bought phone on Ebay. Seller said it is unlocked. IMEI Check came back inconclusive though.
Sim Status: Not Available.
Phone number: Unknown.
Phone did not come with SIM Tray. Purchased google Pixel 3 XL sim tray online. Seems to fit right into slot.
Double checked sim was inserted on correct side. Reset network settings + Factory reset phone.
Sim works fine in Razer 2 Phone.
SIM option greyed out in Network Settings.
QUESTION: Does anyone have any troubleshooting solutions? I would like to switch to this phone and I need the phone to recognize the SIM card.
Clear data in Sim Toolkit.
Network reset.
Check hidden phone settings.
Check sim card electrical contacts... that's all I got.
Return for refund.

Hidden phone settings? you mean developer mode options? Do you know which options would be causing the issue? I skimmed over them and didn't know what I was looking for.

What do you mean by SIM electrical contacts? Are you referring to the hardware?

Ones not accessible to a stock Android user like toggling on the blue light filter. In settings it will be off but it's running anyway. A book reading app did that to me when it did an unclean uninstall. I had to reinstall it, change the setting, then uninstall again to fix the issue.
Perhaps accessible with adb editing but you would need to find it first.
Otherwise a factory reset would be needed to purge the erroneous setting.
