No sim card detected after unlock bootloader - X Play Q&A, Help & Troubleshooting

Hi after unlock bootloader via toolbox i got no sim card detected even after restore factory rom
What could be the reason for that? also its look like i flashed dual SIM ROM on single sim UK version device and its looks working ok

No sim card mostly results from flashing the wrong region firmware.

lokwiz03a and SIM card

Hi.
I was reading how to use lokwiz for the CID unlock. The website said after you execute the CID unlock, the phone gives you a SIM number to unlock the SIM. It said you have to replace SIM cards during this process. It didn't really make sense to me. When installing Molski's latest ROM do you have to unlock both the CID and SIM or just the CID? If you do have to unlock the SIM as well do you really need to change SIM cards, or was the guy talking out of his ass about the switching of SIM cards?
I appreciate you taking the time to help me.
Thanks.

strange problem with sim card

Hi there,
I think problem is intractable . It is a Samsung I9505 recognizing a sim and some not. I assumed it was the flex of the sim card , so buy him a new one giving the same result.
I 've just released by IMEI but that's not the problem. The phone will have 3 years old from Orange.
Where not directly detect and asks pin or anything just he says no sim inserted.
I have installed the latest free firmware PHE is SamMobile and nothing has changed.
Fixed network files and either Chimera .
Anyone have any idea that can happen?
Flash latest firmware and modem?
only the latest firmware one file in odin box pda
someone else to help me, not you think of anything else?
Is your phone unlocked to use other sim cards than Organe ones?
Is the sim not recognized at all or are you getting the message that the sim card was removed?

SM-G935FD (Unlocked) shows invalid SIM card (network locked)

After flashing some roms and custom kernels my S7 edge which was unlocked couldn't identify my SIM card. It detects it but it doesn't show the service provider name and there's a notification which asks me about an unlock code. It's the first time I've come across a problem like this where an SIM unlocked phone seems to have turned into a locked one. I've already done factory resets, flashing the latest bootloader and modem, switching to another SIM card (same result) but nothing works. Is it one of the files being modified or related to hardware?
Currently I'm using Phoenix ROM v3.0 and VoLTaqe 4.2 kernel (best one i have). Also, other roms i flashed also had the same issue.
same here. Eve figure it out?
Was it originally unlocked or was it unlocked with a pin? Some pin unlocks are dubious and only last until updated/flashed.

After flashing global rom network is locked and can't deactivate dsds

Basically I flashed a global firmware H8166 DUAL for it and now I realize it's actually a single sim so initially problem was that Sim card had NO SERVICE I tried it on different phones they work perfectly so I assume problem is either that network is locked or hopefully just because I flashed dual sim firmware instead of single one is causing all this?
I tried turning DSDS off but it switches back on its own
WILL FLASHING SINGLE SIM FIRMWARE FIX THE ISSUE?
Just flash the single sim version then & remember to delete simlock.ta from the flashing pack.
