Galaxy SL shows "Insert sim card"

Hi, I am using Samsung Galaxy SL I9003 for couple of weeks. 2 days ago I found a problem that showed me "Insert sim card". I gave my set a master reset and then the set was ok. But I got the same problem today. I tried the same way. This time master reset is not working.
My IMEI is 354949040415515. PDA:I9003DXKB1, CSC:I9003OLBKB1. Firmware version:2.2.1, .
If someone knows about it. Please help me. I will be grate full to you.
I think you have problem with contacts of your sim card. Try to clean them. Also you can try to show your phone to the service. I don't think this is problem with your firmware.

First advice is never post your IMEI no. in public thread.
As IMEI is intact there should not be any network related issue due to non registration of your device at centre of your network service provider. I feel it could be hardware issue with the SIM card slot. But not necessarily hardware, it could be even problem with your SIM itself. If its used for longtime. first test with another SIM card, may be from a friend or a family member and make sure its not a sim problem. Then if you some how you think it could be related to Firmware you have DXKB2 FW available for flashing as single PDA file. You can upgrade by flashing it from the I9003 firmware thread of Krrazyy or from Samfirmware.com. If that does not solve your problem, take it to service centre for hardware repair. All the best.

Hey, I flashed with DXKB2 last night and my phone acted ok for couple of hours. Then the problem has started again. Another thing is, now it doesn't show my IMEI in setting option or after pressing *#06#......even after pressing *#1234#, it shows me the PDA and CSC, but it shows "Phone : Unknown". Is it a network related issue? If yes, wht to do now. Thanx for the previous comment.

Not network you wiped your phones IMEI with the flash .
You backed up your EFS folder then just restore it .
NO apart from why not you need to find the EFS restore thread that may help .

Thanx buddy.......Another thing I want to inform you my phone shows "Baseband Version : Unknown". I showed it to the customer care and they said that the problem is with Baseband version. They also said that it's a software related issue. But my problem is it showed the IMEI and Baseband Version for 2 hours after my flashing. Then it started again. What type of flashing is going to help me?
Another thing, Can u please tell me or give me a link about restoring the EFS folder? I searched it in google.. but no result!
In addition I am using it from Bangladesh. As far as I know it is not officially launched here. Do I need any unlocking process? If yes, how can I do that??
N.B: Even kies is unable to connect my phone right now!!!!
I have the same problem
Hi, I have exactly the same problem on my Galaxy SL i9003. Did you finally manage to solve it?
to restore imei you need to have backup of your working imei efs folder.i see you have your imei number written here not sure if it is possible to mode efs folder to fit you phone.

It's been a long time. I was frustrated and stopped trying of repairing my phone. Now I see some light. Some people are talking about efs restore. I samsung captivate, a developer showed the way to repair imei and product code without even using pc.
Is it possible in I9003?
And hey, can u please tell me now whether I can mode my efs with that IMEI.
Please help.
this could be a hardware related issue also !
may be the pin where the sim card is inserted went inside or was bent..
or else insert any other sim card and see if ur phone works or not..
3rd this could be a corrupted sim card problem.. my sim card got corrupted and no matter in which handset i put my card in the phon won't boot ! btw it was a BSNL sim card..

If you made a backup of your efs folder, then via CWM it is possible to restore it. If such a backup does not exists, then things are really complicated. maybe you can use the backup of some other EFS from a different i9003, and try to modify the IMEI with yours that can be taken from outside the box. I don't know if you can do the last procedure but some expert maybe can!
Good luck.
I had a similar issue with another phone and sim card, similar to the contact issue. why not take out your sim and put it on a flat surface to see if it's still flat as it should be? if it got hot and became slightly warped, you'll have to bend it back (CAREFULLY!!!) so that the contacts are in contact again
if this is the case, you have to get a new one at your service provider so it doesn't keep happening...
Moved to General section since it has nothing to do with development.
Unless it does and I somehow missed it, if so just pm me and I'll move it back.
And see if u inserted sim card d wrong way.. It happened to me..
Sent from my GT-I9003
I got this problem too.
It suddenly happened to me when using stock room (xxkb1, if i'm not wrong), and in that time i never flashed anything in the phone, so probably not a software issue.
I tried rebooting billion times, put another sim card, cleaning the contacts, factory resets, prayers and nothing worked. But the weird fact is that sometimes it starts working out of nowhere for 2 or 3 hours and then it stops. It confuses me, because it means it's not hardware too. So then i tried updating to xxkpe and xxkph and the problem still remains.
My sim card is not bent, its not inserted in wrong way, the sim cards work in others phones, shows "Insert sim card" when i try going into network settings, doesn't show my IMEI in setting option or after pressing *#06#......even after pressing *#1234#, it shows me the PDA and CSC, but it shows "Phone : Unknown" (like OP), and i didn't backup the EFS. Everything else in the phone works great..
Could you guys help me out? I live in small city in Brazil and bought the i9003 in Paraguay, there are no samsung customer care or similar nearby.

Who is your service through? Maybe that you have to contact your service provider and have them re-activate the phone.

EFS/IMEI is the "identity" of your phone and each phone has one imei.. if you lost it by flashing your phone you can only use your phone without network.. please make sure that you make an efs backup in the future.. but how it looks you have not lost your imei

me too its happened to me on 18-July-2015 and my
- non rooted g920f
- IMEI changed to 350000000000004
- simcards not working ( not registered on network )
- i have signal bars without simcard !
- and when i reainstalled rom i found updates about 66mb i dont know because of updates or e have big prob here
any solution plz
Maybe a defective SIM card.
Perhaps a temporary network fault.
Your IMEI is corrupted then you are cut off the network!
If you have EFS (IMEI) partition backup try to restore it , for example by this app and you are done!
If you don't have backup of EFS partition you need to send phone to samusng service. (only samsung can't restore your original IMEI number)
regards!
Correct the phone was blocked and i've returned it to the seller. Ebay sucks.

920i - no sim/no registered network after marshmallow update

Hi,
This is my first post but, I'm an avid lurker. I am having some issues with my girlfriends 920i. It received an OTA update to marshmallow and ever since it won't read the Sim card. I've tried to flash the official fw through Odin and still having the same problem. Because it doesn't read my Sim card, I have zero access to any mobile network settings.
I am wondering if when they updated the marshmallow, I lost unlock capability.
Also, her imei and sn still match. Most of the problems I see people have are mismatched numbers, and her phone seems fine.
Any help would be greatly appreciated.
So, I checked the firmware that I flashed and it was INS which seems to be the locked version.
I flashed the INU firmware this morning but still not reading my SIM.
I'm out of options at this point, I'm going to go back to lollipop and see how that goes.
Hi,
I am having this issue for my SM G-920I since 2/3 Jan, 2017. I am using fine on US Tmobile network since Oct 2015, but all of a sudden got the no SIM, emergency calls only and continues to stay like this.. I am curious to know if you resolved the issue and how. Thanks for any feedback!
Help me please
I'm having the same issue. Just flashed INS 6.0.1 firmware on my brand new G920I and now i can't get any mobile signal or data. Tried to flash ZTO firmware for my country, but same issue. My phone was fine before flashing INS firmware. IMEI it's fine too. Recovery shows: Applied multi-csc. What can i do? ((((((((((

Already updated and tried to downgrade to 5.1.1, but no sucess. I don't think it's a hw problem, cause it was working before the INS firmware flash, and IMEI number still shows right, no matter what rom i flash (now on MIUI). Can i clean EFS partition and try to flash ZTO firmware again, or i might lost my IMEI and get more problems? Also, wondering if advanced wipe with everything checked on TWRP can help. (data, internal storage, system, sbfs, cache, dalvik cache)
Can you open the phone dialer and enter this code *#*#4636#*#* then clikc Phone Information, and send a screenshot of what you see in the screen (Make sure no IMEI in the screenshot, before you post it here) ? Also check if Radio is OFF or ON.

Codes on my dialer doesn't work, but i'm sure the IMEI is right cause it's showing in phone information. Also, radio is on cause when i search for mobile networks the carriers of my country appears on the screen but when i click on then, just appears a message saying that can't connect
Same problem, any solutions?
I had same issue for over a year, you can check details in my thread, resolved by factory warranty motherboard replacement (free of charge, even thou knox was tripped when I bought it, and I told lady in authorised repair shop that i don`t have warranty).
Forgot to mention that I also tried to repair it via Octoplus box, both by me and some other people (wanted a second opinion), DRK fixed, few new certs written, etc.), not only by flashing fw via Odin or Smart Switch.
And I was 99% sure it was hw, turns I was right.
P.S. country dependable: - in some countries they will probably want to sell you a new motherboard in Samsung (happened to me), but in other factory warranty will be accepted (probably, if the phone is not older than 3 yrs I guess)

Problem with flash Stock Firmware Nougat. No signal, only emergency Calls.

Hi Guys
First of all, i´m sorry my english is not very good and i have to use a Translator.
I recently bought a used SM-G930F. The previous owner had flashed before so although everywhere says SM-G930F in settings in "model information" says "SM-G930FD". Also when a SIM is inserted the "DualSIM Administrator" appears. Had Mashmallow installed and worked perfectly.
I wanted to try flashing the new NOUGAT BTU firmware stock. I did it through ODIN. The process had no errors. When the phone restarted I see that it has no signal. It recognizes that you have a SIM card inserted but "emergency calls only" appears.
The IMEI was not deleted.
Immediately I downloaded a stock firmware from my country ARGENTINA to go back to MARSHMALLOW and I installed it but the same thing is still happening. Then I tried to download another stock firmware from my country and my operator CLARO ARGENTINA, but the same thing is still happening.
I read in forums that the problem may be the modem, but I understand that is modified in the box "CP" of ODIN when flashing.
I honestly do not know what else to do. I also do not remember what firmware I had before doing the whole process.
I understand I should have backed up everything but I did not.
So I ask you please if you can help me.
Thank you very much

try flashing the specific modem and bootloader of your phone. you might want to try mashmallow modem.
You say I try flash only the modem and bootloader that come included in stock firmware from other countries? Must I only check the boxes "BL" and "CP" from ODIN? Thats correct?

I also tested Firmware flash from several countries in America and others, for example Chile, Colombia, Brazil, Mexico, Germany, Portugal. I also tested with some G930FD firmware from Vietman, Singapore, but there was no case. The only thing that stands out is that with Vietnam although no signal, "allowed" the band 4G, did not allow it in all previous cases, do not know if something to see.
u have any issues with wi-fi?? it looks like a modem problwm to me..
Try flashing the stock rom back with the samsung kies program so it will flash back the original stock rom that came with the phone and see if you then have your connection back. If that works then try to flash the BTU.
