Just had this problem this morning. Suddenly my LHGG LTE6 kit had no internet connection. When i looked at the status page of the lte1 interface it said that “sim card not inserted”.
I managed to fix the issue by keeping the router powered on and looking at the lte1 interface via winbox and inserting and removing the sim card. Had to do it multiple times when finally PIN status was “ok”.
This was very weird because i attached the sim card once while setting the LHGG up and did not touch it at all for about 8 months (until today).
Reading through old posts i see that this is an ongoing issue with a lot of mikrotik products. The sim card slot is a bit faulty.
This i just a PSA if anyone runs into the same issue.
I have the same problem. Interesting, that one of the operator’s card (YOTA), working fine and the other two (Tele2 and Beeline) not working at all (SIM card not inserted).
Changed cards several times, the phenomenon is reproduced.
I have heard that people stick duct tapes to the back of the sim card. Maybe to make it thicker? Don’t know. Anyways would love to know is there something different between sim cards or something inside gets too loose. Because if you insert the sim card once and then it randomly fails on you, this isn’t normal.
Back again with this issue, is it covered under warranty or something? I do not have a soldering station and this is very bad when it happens and i’m 300km away. I like to fix this issue permanently. Product brought from Euro.Dk.
This issue was brought up in ref to the latest newletter 105 on a question from a user.
Did any of you make a report to MT on this issue and if so what is the reference number of the ticket??
