hi, first of all: I have been searching for solution to this problem for ages but the problem still persists
I bought the phone a while ago, worked pretty much perfect, I experienced some random signal lost but right after restarting or some minutes the signal went back, so after some months and after changing my phone screen my signal disappeared completly It once worked with my friend's sim card but just with that card and just one time, I tried differente sim's and operators but got no sucess, the phone recognizes the sim but the signal strenght is null (X)
I already tried the following options:
reset
hardreset
5 different roms (cyanogen, and some stock 975/977 roms)
flashing another modem
4 differente sim's
didnt tried anything related to the kernel, this may solve my problem? seens like my problem is related to hardware problems, I dont know..
additional info: my imei is not blocked or N/A but my phone cant recognize my sim number
Additional info: on the fastboot menu the baseband is "N/A", is that value normal?
Thanks in advance:

Anyone come across this issue before?
My Universal works when there is no SIM card, boots OK & doesn't crash. No problem when I'm at work or home, but no use when I'm on the road.
When I put a SIM into it I have serious issues booting up, having constantly to soft reset until it works. And when it does boot up OK it doesn't last for long before hanging - needing another hit & miss session of soft resets.
Is this indicative of a motherboard issue, or a radio issue?
I have tried several different ROMS (WM5,6,6.1), tried altering the PP setting (currently 8), tried different radio's (1.17 and 1.18)
have you tried different SIM card, or putting SIM into a 'normal' phone?
SIM works in Motorola KRZR ok.
Will try another SIM in the Universal & post the results.
An alternate SIM works better, but does not appear to be 100%.
I have checked the phone, it is SuperCID.
Have used mtty and task 28 55aa to wipe the memory, no errors reported.
Have dropped back to radio 1.15
This is a SIM issue, not a Uni issue.
I will try to get a replacement from my provider.
Thanks JonMorgan for pointing me in the right direction.
Hi,
I'm from Germany and went on Holiday recently to Singapore and Australia. There I bought prepaid SIM cards for internet access. Now that I've returned and use my german SIM again, my phone can't enable the data connection anymore.
I've attached the *#*#4636#*#* phone info screen. I already tried factory reset, reflashed a radio image and new rom - and still the problem remains. I also tried all the different radio band settings (see second screenshot). It always says "fail because Radio Not Available).
I didn't flash or change anything on my holiday trip, so I'm really out of ideas. I hope someone can help me.
Thanks
Björn
Set network type to GSM and try again.
SwiftKeyed from dGB with Transparent XDA App
error message stays the same, also tried the other network type options, always the same
I just tried a SIM from a firend of mine, and with that one everything works normal.
So it seems to be a problem with the sim card. I guess I will just get a replacement SIM.
Hi, I have a problem with my device. Disclaimer: I'm very noob so please be patient.
I'm starting to get SIM CARD REMOVED error since i changed my network provider. My previous sim card was not LTE, just 3g and it had no problem with the device. The new sim card is LTE. It took me literally 5 days after enjoying the new network provider till my device acting weirdly.
Before changing, I upgraded to MM. Originally my device does not support LTE, but then I played with the system (sorry for bad terminologies) and make the feature available. No problem detected with old sim card.
So, I tried the old fashioned way; Hard Reset. I had the device reset twice but nothing changes. Frustrated of the constant automatic reboot, I wiped all system, delvik, cache, etc using TWRP. Then i installed CM13 and use it as my OS. It works well. I got the signal with LTE data. Realizing that the ROM does not come along with Google Play Store, i installed gapps. Soon after restarting the phone, the signal only lasts for an hour then it says " NO DATA SIM". I figured a temporary solution which is, rebooting the device after you lost the signal. It is just temporary though. The signal will once again lost.
What I have tried: 1) Locking the simcard while the phone still got its signal.
2) Changing values using this guide-> http://forum.xda-developers.com/lg-g3/help/annoying-lg-g3-problem-lte-signal-solved-t3293721
* My sim reader does not seem to be having any defect.
Any help would be greatly appreciated! Thanks!
Hi everyone.
Recently I have had some issues where sim cards are not working on my phone. At first I thought it was an issue with the sim cards but when I tried the sim in a different phone, it worked fine. I tried numerous restarts, taking the sim out and placing it back in (in case there was an issue with the contacts/sim tray) but this has not solved the issue. By chance I was looking at the phone identity menu and noticed that the IMEI and the IMEI SV fields both say unknown but the device serial number is fine.
I restarted the phone into download mode and checked the System info menu and IMEI number is displayed there but for some reason it is missing in the actual android OS hence I cant connect to the mobile network to make calls etc.
This all started recent after I had come back from abroad (had been using a foreign sim) and tried to use my UK sim. Up until that point, the phone worked fine with the UK and foreign sim. After inserting my UK sim, there was no signal. I got home and tried the sim in my other phone and it worked fine.
I have not modified the phone in anyway (other than flashing an official RUU to fix a boot loop issue - see here ) and it is boot locked and not rooted. After fixing the bootloop issue, I have applied all available OTAs that my phone detected automatically which upgraded the android version to 7.0 (OS 4.28.401.3).
I have tried factory resetting using the menu (not recovery mode) and this has not solved the issue. Any ideas as to how I can fix this IMEI issue?
Many thanks
Rob
Have you checked the apn settings are correct?. Have you checked other UK sim cards in your device that are known to be working?. Do you use a simcard adapter?.

Yep.. tried other simcards thats work in other phones but they wernt working on my phone.. most likely due to the missing IMEI. I also noticed that the colour of the icons on the pulldown tray were red instead of blue and the phone was sluggish when toggling wifi on and off or entering/leaving Airplane mode.
I managed to fix the issue in the end by downloading an RRU and flashing it from SD card. Everything works ok now.
Thanks for your contribution :good:

Hello
I have just received yesterday a Note10+ and everythings work fine.
Howover since this morning the cell network just constanly reset (status switch between Disabled network and No Signal)
The phone also asking for sim card pin everytime. (Most of time for the 2nd time but ask some time for the 1st also)
Question : does a full odin wipe with Efs clear can help ?
Thank you
Have you checked the sim card?
Yes phone has 2 sim card from 2 provider tryed swapping, one sim card nothing worked
I finally ended with full wipe with odin and fixed the problem but i guess the background problem is still here since i can see randomly the signal bar going complety disconnected (crossed circle) before going back a few second after
I guess there is a software issue in Samsung rom since odin fix the issue
