No Cellular Network Available/Google Play Icon - Android Q&A, Help & Troubleshooting

Just installed Slimrom d2att 6.0.1 build 2.1 on Samsung S3 SGHI747 with ARM 6.0 Nano from Open Gapps.
Previous to flashing Rom above I had Slim 4.4.4 build 7.0 Official 5979. Recently had a new sim card installed at a local AT&T store and phone was working fine before flashing Rom. I followed procedures from Slimrom "coming from another ROM or Android version Clean Flash but did a factory reset, wipe cache, and then using TWRP wiped dalvik, cache, system and data, then flashed ROM and Gapps.
Problem: "No SIM card" message. Would factory reset mess up the IMEI? Does this sound like a problem with IMEI?
Pointers and possible fixes are appreciated.

Ended up going back to Slimrom 4.4.4 where Sim Card is identified and Cellular Networks are available. Not sure the new Slimroms 6.0's work on Samsung S3 i747 unless you manually configure.

[Q] Problem with Modem

Hi,
I have my GT-I9300 running the stock Samsung 4.3 rom and everything is working, the device is rooted and I have Teamwin 2.8.1 recovery image installed.. However, if I try to put on any of the 4.4.4 custom roms like CM11 or LiquidSmooth the port goes fine and the device boots clean but my IMEI is blank when it loads and I cannot make/ receive any calls.
I have done the Format Data, Wipe data, cache, dalvik cache all to no avail.
Any help on this would be greatly appreciated as would prefer not to use the Samsung bloatware.
TIA
Trevor.

Sim card N7100 not working after CM12.1 update

Hello,
i installed the unofficial CM12.1 for the N7100 device from here (cm-12.1-20150530-UNOFFICIAL-n7100.zip):
http://forum.xda-developers.com/galaxy-note-2/orig-development/cyanogenmod-12-alpha-1-n7100-t2949644
two months ago.
Everything works fine until i decided to update the system because OTA was recognizing a new update...worst idea
After the update my sim card was not recognized anymore. After i wiped cache and dalvik via TWRP 2.8.7.0 and installed the cm-12.1 version from scratch the problem still exists. If i try to get my IMEI-number via the dialer (*#06#) the dialer software just crashes.
I installed gapps from here: https://github.com/cgapps/vendor_google/tree/builds/arm (gapps-5.1-arm-2015-07-17-13-29.zip)
Any ideas how i could get my sim card to work again?

"No Service" after flashing Cyanogenmod

I've unlocked my bootloader using the unofficial method and have flashed Cyanogenmod 13 (http://forum.xda-developers.com/redmi-note-3/development/rom-cyanogenmod-13-t3431866) with the firmware from the 2nd post.
Unfortunately I'm unable to get any service/signal since doing this, initially it said "No Sim Card" but restarting has turned that into "No Service". I can see in the phone status that it's recognised my phone number and provider.
Is there something else I need to flash (the radios?), any help would be appreciated. Thanks!
You may need the modem files from Kate (International Version), https://www.androidfilehost.com/?fid=24724405900804229
Thanks seapoint.
I've flashed that and I now have signal (I'm able to receive SMS) but I'm not getting a data connection, 3G/4G aren't working. Is there a setting I need to change to get this working?
Have reflashed everything from the beginning in this order:
- Wiped data, system, cache, dalvik
- Flashed CM13
- Flashed gapps
- Flashed Kate modem files
This has resolved the issue and now everything is working as expected.
Thanks again seapoint.

Sim is not working after Custom Rom.

I rooted my phone then flashed TWRP installed Lineage OS but the sim is not working now. Imei is there, I tried RR, Lineage, Cloudy but still it's not working. The is currently on RR android 7.1.2 rooted and twrp is installed. Kindly help!!
What is your carrier? I recently switched to T-mobile (GSM) from Verizon (CDMA) on my vs985 with rr 5.8.3 35B bootstack. I should have full 2G, 3G, 4G, and LTE support, but I get a "no sim card" in quick settings:
https://frequencycheck.com/carrier-compatibility/B3jDu9/lg-g3-vs985-lte-a-lg-b2/t-mobile-united-states
Others have also confirmed support, but they might be on untouched stock firmware and roms.
My SIM isn't recognized, so I heard the following (which I'm about to try):
https://forum.xda-developers.com/verizon-lg-g3/development/xdabbeb-s-vs980-2-0-0-t3231279
1. Flash xdabbed 3.1.1
2. Do a full wipe
3. Flash lineage or whatever ROM you want
4. Flash gapps
5. Flash 35b bootstack (modem includes)
6. Wipe cache /davilk then reboot and it should fix it.
Now that I remember, I never flashed xdabbed 3.1.1 firmware because I assumed it was a custom ROM, but anyways I still have everything working without it, except for this recent switch of mine to T-mobile from Verizon.

Mobile Network not working after flashing

So I figure out what I've done wrong.
I had to update the FW to move from 16.1 to 17.1
This is what I have done by mistake
1) format
2) factory reset
3) wipe everything
4) Flash the Poco fone ROM-GLOBAL-RECOVERY-V10 version coming from xiaomifirmwareupdater (Big Mistake cause I wanted the FIRWARE update only 2Gb FILE)
5) Flash LineageOS 17.1 OFFICIAL nightly 0829
6) Flash gapps pico
After that Wi-fi works but Mobile Network won't work anymore
So I try:
1) to change the SIM card slot
2) to select LTE only
3) to reset network configurations
4) to factory reset
nothing seems to work
Now what I'm trying to do is to
1) format
2) factory reset
3) wipe everything
4) Flash FW-GLOBAL-10 version coming from xiaomifirmwareupdater (AROUND 90Mb FILE)
5) Flash LineageOS 17.1 OFFICIAL nightly 0829
6) Flash gapps pico
But still....Mobile Network is not working at all....
Any hints or ideas on how to fix this issue?
More info about the issue!
So I made a few more tests.
If I have a SIM Card from another Carrier the Mobile Network starts to work
If I try this SIM Card which is not working on my Poco Fone on another phone the Mobile Network works on that second phone
If I try a SIM Card from the SAME Carrier as the first it does not work
So I assume there are some files to delete manually cause any kind of wipe, format or restore to factory/reset fails.
Anyone? ....
Did you solve the problem? I am facing same kind of problem after flashing Magisk.
