Hi everyone,
My MikroTik router is not detecting my Ooredoo SIM card. It shows as if no SIM card is inserted at all.
I have restarted the router multiple times, but it still does not recognize the SIM. I am attaching a photo of how I inserted the SIM card into the slot to verify if it is in the correct direction.
Is there a specific configuration required for Ooredoo Tunisia, or is the SIM incorrectly inserted?
Thanks for the help!
Well, which Mikrotik device (model) is that one?
Is it a Chateau?
You do understand how you posted two photos where you are inserting the SIM "one way" and "upside down"? 
One of the two is surely "wrong" 
.
A SIM inserted in the "right" way should be detected, then whether it works or not it is another thing.
Not Chateau for sure, I have 2 of them, near SIM slot it should be drawing (on Chateaus exists) on which side cutted part of SIM must be inserted
Maybe the OP, being confused.
Can I see a Cap on the first pic ???
So the sim card is not inserted into a Mikrotik Router.
NO, is a "LAMP 5G R16"...
Not that the icon is actually very easy to understand.
Can we try another way?
Contacts should be on the upper or lower side?
The dent should be towards the inside or outside of the device?
And on the right or on the left?
It seems to me like it should be upper/inside/right, i.e. second photo is correct, right?
added another image to previous post...
must work if the slot is not damaged to press the SIM on wrong side...
really, is very clear, for me...
So it is the first photo that is correct.
Contacts on lower side.
Notch towards the inside and on the left.
Just like the AI generated image 
Now you are holding the LAMP upside down.
The Icon of on/off should have the vertical bar up, and also the
uI ƎoԀ
tells something ...
wtf, why this long discussion? sim card slots are like microsd slots: you can't put the card wrong way. Unless you apply extra force......these sim slots on Mikrotik are push to release. So the card does not lock in when put the wrong way.
eh... appunto...
Unless nano-to-micro SIM adapter is used, then extra force is needed because these slots are not designed for adapter tickness. It is possible to insert SIM with adapter, but push to eject is not working because it is too thick on edges.
I've used nano sim with microsim adapter. Even different ones. Never had a problem. But these adapter always came with the sim card.
IDK, maybe it is just Chateau slot issue then, on both I have - LTE12 and 5G R17 ax same issue with different adapters. Maybe it is even better like that - I don't need to worry for losing SIM contact when moving device 
Thanks for the advice, everyone! To clarify, the exact issue is that I keep getting a 'SIM card not detected' error on my LAMp 5G R16 (running the latest update version).
Is this a known physical slot issue with this model, or a software bug in the latest firmware? Should I return it as a faulty unit (RMA), or is there a specific troubleshooting trick to fix this?
