[Q] Help - No sim card error

Hello,
i have got a S4 which has been rooted and flashed. It worked fine for a while but now every now and then i get a error message saying there is no sim card in it. When i reboot the phone it works normal again, without touching the sim or opening it.
I have cleaned sim card and contacts but that did not help.
Any ideas what else to try?
TIA

Hi ,
SIM card problems if they are not hardware related , they are usually caused by IMEI ( efs folder) or wrong modem if you have and efs folder backup , restore it.
What S4 you have , what rom do you have , what modem do you have??
When it fails to recognize the sim card check your IMEI dial *#06#

Hello,
i have tried everything i can think of without any success. It is a Samsung Gt-I9505.
The problem with checking IMEI when it does not recognize the SIM card is that i can't do anything but restart it. There is a error message with restart as the only option.
Now it is doing it as soon as it starts up. I never have to remove the SIM card so the phone recognizes it, just a simple restart without touching the SIM is enough.
I am on the last official Australian ROM. Baseband I9505XXUGNH6, Hernel 3.4.0-2309103 Build number KOT49H.I9505XXUGNH6
I have tried it with another SIM and same thing happens so it is not because of the SIM card.
Any ideas what else to try? I do not have any back ups of anything.

Hi mate,
Your case is not clear , it does not look like firmware but i would not discard that possibility , do you have stock or custom rom? try to reflash
Also there is a chance for what you tell me that the sim caddy may be defective

I am on official ROM, flashed over ODIN. You recommended to check the IMEI when this happens but i can't because the only option is to restart the phone.

Please more details
When you have the no sim errors it does not allow you to dial *#06# ? why does the phone freeze ?

No, it does not freeze but a pop up shows with only one option "restart". I tried to touch the screen, home or return button but nothing works but touching the restart button.

I see, is strange if you said that whith a reboot works fine it make me think more in a hardware issue...maybe the sim caddy..

This phone is driving me crazy. The replacement SIM reader arrived today and i replaced it. Now it does not find any SIM, just getting NO SIM error as soon as it starts up. I tried putting back in the old reader but the same happens.
Anyone any idea what to do or just recycle the damn phone?

Come on guys there must be someone with an idea

You need to flash your device modem files. Is it your baseband unknown or not..?

even i had this problem but i solved it. so first check u r imei number is present r not by dailing the number *#06# a box will popup if it is empty means u have to flash the IMEI first. or it is present means then u can give a clean flash by mi flash tool with the latest rom. just try this if you have any problems while flashing means then try the stock rom which is meant to be for flashing in the recovery. because i have tried both and both where success.

No Network

Hi good people, I am facing a problem. Around 8 hours back I tried calling someone but the call didn't connect so I restarted the phone and then I lost the network. I tried reboot, flashed different ROMs (unofficial CM14, cm13 nightly build n MM nougat backup), tried with GAPPS and without GAPPS but the problem is persisting. I even tried swapping the Sim cards before that but of no use. I tried debugging by using *#*#4636#*#* but ping test is failed and also there is "TURN RADIO ON" I believe ideally it should be "TURN RADIO OFF". please have a look at the screenshots. I'm almost dying without making important calls.
Update: Guys I have got it working.. Kindly look into my below posts. Please don't misguide people for small issues.
Thanks

In the screenshot we can also see, GSM SERVICE IS OFF. it stays the same even after clean flashing a new custom ROM.

Got it working. Flashed latest COS ROM file however the situation was still the same. Then I removed sim, switched on airplane mode restarted. After reboot inserted Sim then again restarted n then I got the signal
1. Removed Sim card, switched on airplane mode from both power menu and notification toggle.
2. Restart, inserted Sim card and switched off airplane setting from setting. (Notification toggle and power menu didn't work) then got the network.
Please note I tried with only one sim in sim 1 tray. Later I got the network for 2nd sim as well

Which rom did you flash and what was your method of flashing?
You also said simply flashing didn't work. It was what you did with reboot, aeroplane mode and taking out and reinsert the Sim that worked?

I've had the same problem for almost a month now... and i gave my phone to the service center. They called up to inform me that its a motherboard failure and they'll fix it.. I'll provide further info when I get my phone back (probably in 3-4 days)
P.S I tried almost every method to make it work. So if you couldn't make it work in first 2 days or so, dont waste your time and just give it for the servicing (make sure its in Stock OS so that they dont ask any questions about root xD )

I flashed almost every latest ROM. But no ROM got the network back. So as a last resort I flashed COS 12.1 and still didn't get the network. Then I removed both the sims, activated flight mode restarted the device, left it couple of minutes and inserted only one sim in first slot. Holla I got the network. Then everything is back to normal
If u r facing the same problem I would suggest u to activate flight mode n restart. If it doesn't work try by removing sim cards, if it still doesn't work try COS 12.1.

Usual procedure of flashing. Wipe cache, dalvik, system and data. Flash ROM + Gapps. Reboot

Try to search in the forum. There is a lot of threads with the same problem with the Zuk Z1. It is a hardware problem.

Your modem and baseband sections may be damaged. Modem structure is hidden under qualcomm structure. To Access and repair those sections, you need to do some modifications. I managed to make my Zuk Z1 worked again with some tweaking. Altering that part of the phone is illegal due to its restricted elements such as IMEI number. That's why I cannot post a tutorial here. İt is not allowed. However, I can help you if you personally contact me. I hope you get your signal back soon.

Please follow xda rules and don't tell people illegal things where they get in trouble. Keep in mind, that's not an illegal forum

Sure thing but I have already mentioned it. I didn't post anything illegal. So, take it easy.

DO you have the global or the EAA version? If you have the global version you can try to flash full package of 1.1.4 to solve the issue.

How did you do the full flash? There is a tutorial in here where 1 command is false i think.
its flash fastboot xbl xbl.img but it should be fastboot flash xbl xbl.img.
Maybe thats what you need to repair but i think xbl image is about ram....

My imei is normal no problems

Maybe I can help with a solution: I have 2 SIMs and my mobile data suddenly stopped working one day. (It seems because the mobile carrier had technical issues in my area.) Now as I use mobile data only on SIM1 which I de-activated during the day in hope to get a connection back, I assume my preferred SIM changed (see Settings -> Network & Internet -> SIM Cards: Standard SIMs) to SIM2 for calls and mobile data. As the phone tried SIM2 for data but it is de-activeted there, both networks had a small "!" near the radio indicator. After settings the preferred SIM back to SIM1, everything is working fine again.

The problem is that the cell phone doesn't recognize any chip, so I can't open the sim card options

Hello i have also updated to 1.1.4 and after around a month it is also not recognizing my sim card. The sim card works on any other phone. I have tried rebooting, soft restarting, resetting all network options, I even changed the sim at the store. Nothing has fixed my issue. My last resort is factory reset.
Has anyone found a solution?
