[ZE551ML] Phones does not recognize inserted sims. IMEI value shown as unknown! - ZenFone 2 Q&A, Help & Troubleshooting

I inserted SIMs in both the slots, still it shows no sim inserted icon in statusbar but for only I SIM tray. Usually when both the SIM trays are empty it shows two no SIM icons. The phone is acting like it's not a dual SIM phone :: 1) Settings->more does not show the usual "manage sim cards" option. 1) Settings->about does not show the usual "SIM 1" and "SIM 2" option, just a single "SIM status".
IMEI information has usually two entries but now only one and it shows the IMEI number as known!
Please check the attached screenshots.
What's happening with my phone? Tired RR Custom rom same there. Now on RR Custom Stock.
EDIT :
Everything normal after flashing RAW firmware. I thank the community for the help and support.

You can try this, it worked for me: https://forum.xda-developers.com/zenfone2/general/asus-zenfone-2ze551ml-ze550mlunlock-t3564309

[Q] How to force the sim unlock screen?

Hi,
I have a SIM unlock code but when I insert a new SIM it doesn't prompt for the unlock code.
I don't know if it has something to do with the fact that my phone asks for the language every reboot and it "covers" the unlock screen.
Is there a hidden menu or USSD code that I can use for type in my SIM unlock code?
Cheers

You installed a KK version and have wrong baseband, kernel or something else wrong. Nothing you can do about it except flashing correctly according to the guide here in the forum.
I flashed the custom KK rom and had the same problem. Only by following the guide on how to install KK with locked dual recovery and root very exact, I got it working.
I thought that I followed the guide step by step but I'll give it another try
Thank you

Hi,
I don't have the "Sim card lock settings" in my Security menu.
but if I go to the "service Menu" - Service Info - Sim Lock y shows an X on "network" and a 5.
I think it means that it is locked and I have 5 unlock attempts.
BUT if I put a new SIM it doesn't recognize it and it doesn't prompt for an unlock code
Q u,z

Try this? I did this to unlock a ZL (Jellybean) last night (not intentionally, this is just the order in which we happened to do it).
1) Put in correct SIM (a SIM that has the carrier in which the phone is locked to)
2) Do the initial setup stuff to get it out of the way (this is so it doesn't bother you with it again and again)
3) Power off, put in illegal SIM, power on. It should ask for unlock code without anything overlapping it.

Zenfone2 ZE551ML - Sim card issue with CM13

Hello,
Currently i am running the latest version of CM13 (cm-13.0-20160307-UNOFFICIAL-Z00A.zip ) on my phone, but this issue also occured with the other versions starting from the 1st of march.
With 2 sims inserted in my phone, both of these sim cards work fine when i put them separately in the phone, however when i put them both in some weird issues occur.
The problems start when booting my phone, the phone asks me to enter the PIN for sim 1, which works and connects the card to the network ( and fetches my latest messages and such )
Then the phone obviously asks me for the PIN of my second sim, which it accepts. However after accepting my SIM the same popup comes up asking me for my PIN for sim2 again.
And when entering the PIN it gives me the error : "SIM PIN operation failed".
After multiple attempts, it finally gets me in the phone. However the data on SIM1 is not functioning anymore.
What i've tried is:
Multiple different CM releases from the past week
Putting my phone in airplane mode and out again
Factory reset the phone
Does anyone know how to fix this issue?
