Glitchy SIM-card once ever hour?

Once every hour my sim-card glitches out.
And then comes back automatically after one minute of downtime (see log below)

Why is this?

I use it on brigde mode, turned off DHCP (as you can see) but I dont think that the problem.

Could it be fysical? That the SIM-card needs support somehow? (i did some manual configuration of the sim-card adapters when installing the SIM-card (or it wouldnt fit)

Try IPv4 only and Auto APN

Good day,

Thank you for your query.

I am picking up on the network event log you have shared in line with SIM status, that the SIM state reported by the internal modem a change of SIM card not inserted.
e.g. line 55 “2024-10-04 08:24:19 SIM status SIM state changed to not inserted (internal modem)”

This can signify that the issue is related to the SIM card perhaps losing contact with the SIM pad, this can be caused by multiple factors, it can be that the router is operating in a high humidity or high vibration environment. We recommend the usage of a thin coat of dielectric grease on the SIM card contact to keep it in place in any of these factors.

In addition to this, i would also recommend removing the SIM card and cleaning the contacts, reinserting it, and checking if that helps.

Thank you

Turns out, I am the problem: inserted the SIM-card sloppy.

Solved by some extra tape :innocent::blush:
