No Sim or Sim Error - AT&T Samsung Galaxy S6

I reflashed stock on my galaxy s6. Now my phone isn't recognizing my SIM Card. When I make a call I get "No SIM or SIM error". This SIM was working earlier today.

I've tried the following:
Wipe Cache
Wipe Data/Factory Reset
Reseat SIM CARD
Nothing has worked yet..

Anyone?

Someone has mentioned that if Knox trips that it suspends the SIM service? Is that possibly true?
I checked KNOX and i checked it was 0X0 so I assumed it is not tripped.
I also just tried to reflash everything to stock via ODIN, still no cell service. Has anyone else ran into this issue?

What FW version were you on before you flashed stock? And which stock did you flash to OCE?
I was on OF4, ODINd to OCE and had no cellular service. Sim card wasn't recognized, Network, IMEI, Ph#, were all "Unknown" and Baseband was "Unknown". Flashing the OF4 modem.tar.md5 and boot.tar.md5 gave me service back, but I couldn't update back to OF3 or OF4.

Note users, need help. I got the i717, rooted it and

and flashed the tmo radio and unlocked it via service menu.
What do I do next to use it with Tmo? Do I have to flash a tmo ROM or simply insert a new SIM card and that should work? Please help me to get this thing working. Thanks.

Note 5 N920A Lost Imei Lost Baseband

Hi.
I have Note5 at&t and it has Bootloader.
When I was trying to flash another stock at&t firmware, I've lost my IMEI number. As I learned, in order to get back my IMEI, I have to flash my old firmware, but I didn't memorize my old firmware name. And because of the bootloader, there is no way to learn old firmware's name with the root access. I can't root my device. Is there any solution?
Thank y'all in advance.
hi, i have the same problem, tried to downgrade to marshmallow but got an error, i flashed stock AT&T nougat firmware and now have no imei info or baseband info, i have tried flashing n920aucu4eqk6 and n920aucu4eql1 which are the 2 latest firmware versions but still having same problem...help! please
in case this helps anyone, i managed to solve my issue, i downgraded firmware to a 5.1.1 combination firmware, where the baseband and the imei were still being picked up by the phone, then i reflashed the phone with PK1 marshmallow rom (except i did not flash the CP file), only flashing the BL, AP and CSC files and now the phone is running marshmallow and picking up the imei and baseband information and can make calls and send text and picture messages.
thank you

How to go to unlocked firmware on Binary Version 5, after sim unlock

I purchased a sim unlock service to get my Note 8 off the Sprint network. However, every time I restart the phone it tells me to insert the service provider original UICC and it constantly tries to setup my service then fails as I do not have a Sprint card in it.
Just to clarify, my ATT card does but I want to install either unlocked firmware or ATT firmware to get the best signal. However, I cannot find either with the binary 5. (U5)
If someone could point me in the right direction I would appreciate it.
I have already looked at the Carrier switching guide, and it does not have the correct files for the binary 5 version.

Question Changing service provider software version

How can this be done? I'd like the stock UK one (BTU service provider I believe?) as currently it's showing as VOD/VOD EUX etc.
Will my data be wiped? Is it really worth changing and going through the hassle? I've always had stock firmwares either out the box or flashed on Odin by myself but this time it didn't remove the carrier stuff.
I did initially flash the latest stock BTU firmware (all 4 files including CSC not home CSC), yet was still met with the carrier apps and the service provider info says VOD, I'm on Three the phone is unlocked but from Vodafone
