Hello,
I had CN ROM version with Kit Kat. Everything worked fine but one day I lose sim cards. I mean sim cards weren't detected and WiFi was 'Switching On' I mean flashing. Phone is constantly restarting by itself. I've done several factory resets, take out the battery and flashed phone with ROW ROOM (I've change the NON-HLOS file to get network) but nothing helped. Flashing went ok and I've got new ROM.
Phone is restarting after few minutes. I can not switch on WiFi and sim cards are not detected. Do you have any solution for that?
Thank you!

Hi, I recently started having trouble with my gf's phone (Nexus 4 running lollipop 5.0, lte enabled, tmo). It started shortly after I enabled a SIM lock pin on the sim, but not sure if that's the cause or not... The phone started to intermittently drop signal, and would not make calls (it would just appear to be dialing, but you'd hear no ringing and never connect). When I'd restart the phone, I could usually make a call. I tried to fix it by restoring everything the stock image, rechecking the apn, making sure stock radio was installed, etc, but the problem persisted and eventually got to the point that voice calls did not work at all. LTE and data worked to get onto the internet, but once a call was attempted to be made, it'd lose all signal. I discovered eventually that if I switched off lte/4g/3g, and only kept gsm 2g on, I could make a voice call. Next I tried her SIM card in my phone (Note 2 on Android 4.4, t-mobile) and as soon as I put her sim in, my phone started doing the same thing. After switching back to my SIM (that was working just fine, before), now MY phone is stuck with the same problem! (Can only make calls with just 2g enabled). I'm at a total loss. Has anyone experienced anything similar, or do you have possible solutions/ideas on how to fix this?
Flash stock and unroot you'll be fine

I flashed back to stock image a couple of times via wugfresh toolkit, but got the same results each time. I did, however, just fix my note 2 by removing my sim (the one that was previously working), flashing stock via odin (didn't help in recovery), and then replacing the original sim. This leads me to believe that the sim in the n4 is somehow corrupted and once loaded, permanently changes some settings somewhere. (I hope that's the problem, and not the phone). I'll pick up another sim card from tmo tomorrow and try flashing stock again before loading it. Any idea what would cause this? The only thing I did different was set up sim lock on the card, and it seemed to work just fine for a while, till it didn't... Thanks for the help, I'll let you know if the new sim works.
Solved
For anyone who may be having the same problem, here is how I solved it. I picked up a new sim card from t-mobile, flashed a stock rom via toolkit (with the sim card not installed), loaded rom, installed sim, loaded correct apn. Everything works as it should now.
Hi,
I am having a strange issue with my SIM card and my S4(9505), I was originally using Vodafone UK but I switched to EE roughly 6 months ago and everything was fine to start with. Then about 3 months ago, the phone would give an error saying SIM card removed and prompt me to restart the device, this would happen about once a day so it wasn't unbearable, however, recently it started giving the same error every 10-20 minutes and now it will not detect my EE SIM at all. The strange thing is, the Vodafone SIM I previously used works perfectly fine. Also, the EE SIM works fine in other devices.
TL;DR:
Phone not detecting EE SIM card but working fine with other networks.
Phone Info
ROM: Omega V40
Android: 4.4.2
Baseband/LTE (Modems): XXUGNG8
Condition: No major drops / damage
What I have tried so far
Replacement SIM from carrier - Same problem
Replacement SIM/SD card reader - Same problem
Taking apart and cleaning whole device with compressed air - No help
Detaching and Reattaching all connectors/ribbon cables on the motherboard - No help
Wipe cache/Dalvik - No help
Wipe data/factory reset - Same issue
Revert to stock ROM - No help
Flash full stock firmwares for EE, Vodafone and unbranded - Same issue with every one, as well as 'android.process.acore has stopped constantly'
Airplane mode trick, as described here(http://forum.xda-developers.com/showthread.php?t=2698621#post58245416) (multiple times) - No help
Anybody have any idea?
I Have the same issue. Its is happening more than once in a day. Drives me crazy.
It started when I installed Omega. So I reverted back to another ROM. I think it is something with the CSC or the baseband.
Anyway, I don't have a solution yet.
Hi, I hope there s a hope..)
I got a s4 and the moment I put in the sim card I noticed that it took max 5 min to get the network working. I thought it s not a big deal. Then the wifi was not working with stock and I rooted the phone and started playing with different ROMs. Every time I did a reboot it would take up to 5 min to get the signal, doesn't matter what ROM. 2 days I did a reboot(not the first one on cm12 with alucard kernel) and the phone couldn't get the signal, not after 5 min, not after 3 h. I put the sim in other phones and it worked, I put other sims in my s4 and it worked. When I put my sim in my phone after it had been in another phone it connects right from the start but after 2 min the signal disappears. I changed ROMs, flashed the same ROM, and cm13 and again and no luck. Now the sim is on Huawei p1 and when I get the notification tray down on the bottom it is written 25905 instead for the name of the mobile operator, which is strange. Is there a way to fix this?
Thank you!
Have you considered getting your SIM card replaced?
The carrier should do it for free.
I replaced it before buying the s4. And it also works on other phones.
OP, did U try to flash another MODEM for Ur device? Not some custom ROM, but MODEM? A have some signal troubles, but reflashing MODEM (lastest version for KK) via ODIN fix the problem.
U can find MODEMs and BLs here.
This thread should be in the Q and A section...
I just did and it doesn't work. I went today to their office and got a new sim and it didn't work either. Tried another sim from the same company and it didn't work either. I have no idea what's wrong...((
Hey, I've had my Moto X Pure (XT1575) for a bit over a year now, and it's been great up until I updated it to 7.0 a week ago. It has been saying "No SIM card" and I have been unable to do much with it. Rebooting the phone will fix the issue and cell service will work for for about 5 minutes, then it disconnects again. Taking the sim card out and putting it back in will also fix it for about 5 minutes. I have cleaned the sim card and port, but that has not helped. I have also tried factory resetting the phone but the issue is still there, even during setup. The phone is running stock android with a locked bootloader. Any help would be greatly appreciated.
Replace the SIM card...
Check if another SIM card is working fine with the phone or not. If yes, then you need to follow what acejavelin has suggested above.
Hi all,
I have a problem with my XC, i hope there's someone here who could help me out with this .
I get a SIM card error when i start the phone. After a while (5-10 mins) the error transforms into "No Service" as if the phone now detects the SIM card but has no service whatsoever.
Things i did to my phone prior to this:
- unlocked bootloader
- installed custom recovery
- root
- installed custom ROM
- drm fix
The phone did function properly for a few months actually after these operations without a SIM card error even once. But then i tried to install custom ROMs again (and i'm sure didn't flash ROMs not suited for XC) -actually tried to install "existenz" ROM but i did get a bootloop so i -once again- did the usual procedure with flashtool and flashed a firmware to set everything back to stock as close as possible. That was, when i started to get the SIM card errors. After several restarts (cold and warm) the phone sometimes recognized the SIM card and i could use the phone normally. But this was true only till the next restart, where i got the same SIM errors again.
Things i tried:
- flashed several different firmwares (official) with flashtool (wiping everything) - all the newest firmwares.
- *#*#72786#*#* in dialer to wipe carrier settings
- *#*#4636#*#* in dialer to go into phone settings and changing those settings randomly
- flashed another AOSP based custom ROM instead of stock sony
- wiping and formatting everything between the flashes of course
- cleaning and re-inserting SIM card (which i never took out before anyway)
But unfortunately nothing worked. Phone keeps to not recognizing the SIM card (which is working just fine in another phone). Everything else works just fine on the phone. The IMEI is displaying correct. I'm almost certain that the fault isn't hardware-based (i didn't drop the phone or exposed in water etc.) but software-based. Did i just managed to brick my phone by flashing something related to the modem which i'm not aware of?
I can't find any solutions on google, which help me, which is why i'm posting it here. Sorry for the long post.
Did anyone experience such an error and/or knows what else i could try to fix this? I hope for answers
Thanks in advance!
Anyone?
I've got the same problem.
I didn't unlock the bootloader or anything prior to getting the bug.
I wanted to downgrade to nougat, because aparently it helped someone in the forum below, but I didn't manage to do it.

Did you try nougat, when flashing different firmwares?
Your post makes me question if its worth it, trying to downgrade.
Try to remove sd card if you have one. then restart the phone and see if sim card is recognized.
I had the same problem and I think it was a hardware failure in the end.
I also tried almost all the things you were writing above. In my phone it started slowly. Sometimes the SIM was detected but after some time the connection was lost.
It happened some time after I installed a new battery.
But since there are no original batteries available for the device anymore and the new battery was even worse than the 5 year old original battery, I gave up investigating the SIM issue and don't use the phone any longer.
I bought a new (used) x compact because I still like the size and I saw some development was going on for this device.
In the end I cannot tell whether the SIM was not detected because I broke something while changing the battery or due to age of the phone but I think it was a "normal" failure.
I also read from others that they had the problem and the SIM was working for some time after I switched the battery before it stopped working.
Nevertheless. Good Luck to you. Maybe it is something different on your phone.
