You will need to flash a radio/baseband that matches your cid. Mismatched radio baseband can cause all connectivity to fail. If you don't want to modify your phone, that's your only option. Sorry.

Flash cyanogenmod, do the baseband change again. Switch to automatic. Only cyanogenmod has the automatic network selection option. Stock rom don't have.
This is the only way as I also experienced the same.
problem solve without rooting and flashing

I have a oneplus two and went through the same problem . I read a lot of threads on various sites and found that this question remains unanswered. Very disappointing .I was tinkering just to find something to make my sim work . Fortunately ,I found the fix.Its very easy and a person like me who doesn't even know how to root a phone can solve this problem .
Solution.
Wipe data and cache.
Download the latest stock ROM available and flash it .
Type *#*#4636#*#*. Go in phone information.Open options . Select radio band 40. Just don't select USA.
Download Shortcut Manager lite.
Search engineering mode.(search 'eng')
Scroll down to find
com.android.engineeringmode.network.BandMode
And
com.android.engineeringmode.network.BandMode2.
Find 'Auto' option after opening one of the bandmodes.
The sim should start working.
If the sim doesn't start working , change band and reselect Auto . This should do.
PS. If u don't have any other radio band than USA then try these repairs on USA band . Hope it works. If this works please share this info on other sites and help people.
Cheers !
Anyone found any solution, I am facing same problem after changing radio band from phone test menu.
Please help
I fixed the problem in my oneplus2.. Its very easy

Search "Engineer"
Open and launch "com.android.engineeringmode.EngineeringMode"

Thats all...
You network will be back to normal in a second

Am facing the same problem but with D816w, you see, my device is a Vietnam source (HTC_059) and after receiving the Android 6 update I lost my IMEI numbers due to Unkown Baseband, after some research I did find Android 5 Firmware which is compatible with my CID, I have restored my Baseband with IMEI along but with no Coverage, when i go to *#*#4636#*#* am only left with Automatic band , NO USA No Europ No African or even ASIA,
My device is rooted but with S-ON , anyone can help me with that?

after dialing this "*#197328640#" nothing comes into my screen
Hello! Help is needed!
SGH- I747 Android 4.4.2, I747UCUFNE4 without the Russian language.
4.4.1- sews through ODIN, the error came at the end of the firmware and the phone will not boot.
Then set 4.3, everything works, except for cellular communication, IMEI - zero \ zero.
Question - how to restore IMEI or will only service center?
Thank you in advance for your help.
P.S. English is not my language, sorry for the spelling.
Installed home modem, which originally stood, and restore IMEI. But the phone is not registered to a network, it requires PIN unlock network, although firmware, worked in our network.
Question - how do now unlock?
So the phone used to work on your network and now it doesn't? Is the phone asking for a code to sim unlock the phone?

Hello! Before flashing the phone I worked in our network, and now writes - "SIM network unlock PIN". It is necessary to Android 4.4.2
It Fixable? I read that you can remove the unlock through Android 4.1.1, but it does not put.
Thank you for your response.
Once the phone is on 4.4.2, you cannot unlock the phone for use on other networks unless you can get a code from AT&T or buy a code.

I mean this is gonna sound dumb but have you looked at the mobile networks setting page and have your preferred network on LTE?

Yes
Can you change the network operators on 8.1?
Is your unlocked Pixel XL from the USA? It seems it doesn't support the correct bands for your network
All pixels have the same radios. Dial *#*#4636#*#* click on phone info. Change settings if needed
SIM card is toast. I have had this exact thing happen to me. Just go into a VZW store and request a new one. Sim handshake needed for LTE connection only on VZW.

After you got the new sim and installed it did you go back to factory rom and waited a bit for it to connect to the network?

I'm on the February patch, stock. I'm flashing everything, also, is it normal for your phone number to not be your phone number with a new sim?
My number showing up on about phone is 908-770-6054. This is not my number, could it be human error?

Contact your carrier or go in and tell them that it is not your number and that you are stuck on 2g they should be able to tell you how to fix it or if you go in they can fix it
I did contact my carrier, they cannot figure out what to do. Replaced the sim about 4 times, still no luck. I go into testing (secret code) and I am on 1x network @loeffler23
Sounds like your efs data could be corrupt and there is no way to fix that. Or your LTE radio is toast. Did someone try to carrier unlock your phone?

my phone's unlocked by default and there has to be a way to fix efs, not accessible by recovery? (what is efs)
It holds the imei and other radio proprietary info not sure what partition that data is actually in on this device. I think the efs data is no longer in /efs
Twrp used to have a option for efs backup with the data system backup and restore options
Hey guys,
yesterday my phone got updated to the 3.23 Version. Since then my phone is getting no signal to my provider nor mobile network.
I tried WIPE USER DATA which also doesnt work. The sim works fine in my iphone xs...
I also tried to manually apply APN settings.
After i plug in the SIM card it asks for my pin. I enter the pin and it unlocks the SIM but no signal.
I only get a Question Mark at the Status Bar.
Do you guys have any similar problems?
Greetings from Germany

I updated yesterday & have signal (in Poland).
I suggest that you try to manually switch the network type in settings, to 4G/3G/2G.
