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.

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?
prejudice and first excuse my bad english (google translate) and thanks for the opportunity given to solve problems unknown to us as in my case.
then I state that I understand a little but this is really strange, yesterday I got the bright idea to bring back to the data of the cell factory in question having the TWRP 2.6.0 for lg optimus g pro e986 doing so went in contrast perhaps with the recovery changed by always reboots and always going to end up in recovery ...
after which I started lg flash tool I downloaded the firmware e98620a Italian one I did recover after having finished I found a phone that does not read most of the sim, I have already tried to put other sim cards but nothing I have also tried my card sim in other phones and works perfettamete, now I do not know what to do ....
if you can be of assistance I typed in the dialer 2945 # * 896 # so entering the sim unlock process and any menu press I wrote out this phone is permanetly locked and can not be unlocked.
Now I do not know what to do I ask your help please help
thanks in advance to all
good afternoon friends, I come to you for some doubts that I have about the update of my team .... I have a moto z play with android 6.0.1 I want to update for compatibility issues in applications, but I have activated the good dual sim so I bought it second-hand, can I update directly to 7.1.1? and from there go up to 8 by means of adb sideload? and what is the procedure since I read that you need to omit the lines of the modem and the sfg to not have problems with the imei ..... someone could help me please? and excuse me but occupy the translator to create the theme.
Can we see a screenshot of your Settings>about phone screen please, showing your device and build number? This should help us figure what device you have and what builds to flash.
Provided you flash the correct firmware for your device, your IMEI should be okay.

It does not allow me to upload links, but I leave the details of my system ....
Android version: 6.0.1
Baseband: M8953_10208.08.04.47R ADDISON_ROWDSDS_CUST
compilation: MPN24.104-44
I downloaded the firmware: XT1635-02_ADDISON_7.1.1_NPNS26.118-22-2-12_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml
* I do not know if that serves me, if I can directly flash and if I should omit the lines of the commands Modem and Fsg, to avoid losing the imei .....

Thanks, if you're updating, usually it's a good idea to full flash, including modem and fsg. Else you'll have issues with OTA updates.
Normally flashing stock firmware shouldn't cause problems with your IMEI, but without knowing the history of your device, it's difficult to say. If you want to, could you provide your device's get var info?
A) assuming you have ADB and the Motorola drivers set up on your computer, boot your device into the bootloader. Connect your device to your computer via USB.
B) open an ADB terminal and in the terminal type 'fastboot devices' without quotes. Press enter, that should return your device's serial.
C) if you get a response, type 'fastboot getvar all' without quotes in the ADB terminal. Press enter to display a output of your device's parameters.
D) copy paste that output here or upload it somewhere. You may wish to omit your IMEI from the output. That output should tell us if the device was previously unlocked or flashed with a newer firmware.

ok I understand, I explain the equipment I acquired it from use and has a blockage for non-payment in ATTMX that is why they activated the second sim, I do not have backup of the efs and the recovery does not let me, my idea is to go up to 7.1.1 and then go to Oreo by means of adb and already being there to activate the dual sim again and be able to continue using it ... so I ask you if I can skip those commands to avoid taking risks with the imei

Again, if you're updating with the correct firmware and the device had not been flashed with custom ROMs or had downgraded firmware in the past, I do not think you will lose your IMEI. I would recommend you use those commands.
However, if your device was blocked for non payment, are you sure you can even use dual Sims? I'm concerned the previous owner's network provider may have black listed IMEI 1, so even if you update to Oreo, you may only have one active SIM. I'm also hoping that device is from non payment and not stolen...

I suppose they stopped paying, and if right now the dual SIM is activated in the first line which is the original IMEI does not signal, but in the second that is the IMEI 0 if I can use my line but the same way only works for ATTMX, that's why I want to think that updating to 7.1.1 and later to oreo can activate the dual sim back and that it works again like now .....

Even if the device says it's dual SIM, the IMEI for one of the SIM slots is likely blocked not by ATTMX but for other providers too (hence the blacklist). I doubt if you update whether you will get dual SIM usage, as your IMEI stays the same usually, so even if you're updated to Oreo, you may still have only one SIM active. The network may just keep rejecting that IMEI number.
I'd honestly think about returning it unless you're happy with just single SIM access.

does not look, I mean the original equipment is a sim which is blocked for lack of payment, they activated the second sim and obviously that is 0 which if I line with ATTMX and good until now I have no problem it works for me and apart I bought it cheap, the only thing I want is to update to be up to date and so already updated to activate the second sim

Yup, so if I've understood you correctly
SIM 1) Blacklisted IMEI due to non-payment by the original owner . Likely will not work even if you update.
SIM 2) I don't think this IMEI 2 gets blacklisted automatically, IMEI 1 is usually the one that is blocked, unless the original owner or ATTMX asked for IMEI 2 to be blocked too.
However, I still think if you update to Oreo, you will not be able to activate the dual SIMs. IMEI 1 will still remain blocked. From what I understand, only the original owner/ATTMX can reverse the block, and as it's due to non-payment, you'd likely have to ask the original owner to clear their debt with ATTMX to clear the block. The block exists on the carrier level, so unless you can change the IMEI (which is something indiscussable on XDA), you are stuck with one SIM, despite having a dual SIM model.

if the original IMEI 1 is the one that is blacklisted by the operator, the IMEI 2, which is the one that was activated and is 0, is the one that gives me line, so I wanted to suppose that if I update and when I am in Oreo I could activate it again with the tutorial that goes on the web and thus continue to occupy the IMEI 2 with the line I have ..... now I hope to explain myself .. I doubt very much that the owner pays since we are not in contact.

So you'd likely have only IMEI 2/SIM 2 active, especially if the original owner has not cleared the balance. I do not know of tutorials that could help you restore IMEI 1 (and they are likely not permitted on XDA). I wish you luck in this endeavour to get your dual SIM device working fully.
I have my IMEI only, sent it to ATT for unlocking, and am wondering if this is a way of imputing the number directly.
Background and have tried
Bootloader is unlocked as is phone.
I have tried methods for getting update to see if IMEI is recovered, same with pixel experience method. My issue with them I think is that I recently ported my number to another service, so I have a sim card that will not connect and not get IMEI number from carrier..
Any solutions you know or can point me towards would be great.
