Hi there, I have a Chateau LTE router (S53UG+5HaxD2HaxD) and today I’ve tried to insert a SIM card in the slot under the router.
If I try to insert the card in the same orientation as depicted under the router, it won’t lock into place. In all other 3 orientations it will lock into place. Unfortunately, I can’t figure out what the correct orientation is, as RouterOS tells me there is no SIM in the slot, no matter what I try…
I’ve tried with a different SIM as well, just to exclude there is an issue with the first SIM, but I’m getting the same result. The documentation doesn’t mention much about how to insert the SIM card, I assume because it shouldn’t be rocket science
Does anybody have an actual picture showing the correct orientation of the SIM card?
The router was upgraded today to the last RouterOS version, same thing for the LTE firmware..
The manual says this, I have seen elsewhere on Mikrotik's websites that they mention that you get the best results with a SIM card, that you don't use an adapter, and that the SIM nano card is so much thinner(0.67) than the micro (0.76 mm) SIM card, I'm sure you can stick some tape or something like that behind the card and the adapter so it becomes a little thicker.
Thanks. I’m not using any adapters or so. The thing is that if I insert the SIM card as shown in the above picture, it doesn’t lock into place. It will lock (click) into place when inserted in any other orientation than the one shown in the picture. That’s why I was wondering whether somebody would be able to advise which sides the contacts are supposed to be…
Anyways, I’ll attach some sticky tape to make it thicker and see what happens…
The fact that it clicks in the "other three" orientations may mean that you are not inserting it "deep enough" in the "right" orientation.
BTW it is not unheard of that there are minimal mis-alignments between the PCB and the case and the outer edge of the SIM card (once properly inserted and "clicked") remains inside the white case plastic (i.e. you need a blunt piece of plastic the same thickness and width of the SIM to be able to pudh it all the way in), compare with: SIM CARD HOLDER 3D PRINTED FOR MIKROTIK
I was a bit skeptical, but I’ve tested it with 2 SIM cards: The first one (… a bit thicker card) required only one layer of sticky tape. While the card still doesn’t “click” into place, it won’t move because of the added thickness. The second SIM card required 2 layers of sticky tape, one layer wasn’t sufficient…
I definitely recommend this as workaround to anybody experiencing similar issues. Thanks for the suggestion…
