Hello everyone,
I have a question regarding one of my Mikrotik routers, the Chateau 5G R16.
My phone carrier is an MVNO and is currently switching network, from PLMN 22288 to 22210. When the migration happened for my account, I lost connectivity, so I had to enable roaming and manually set the operator to 22210 in the LTE interface settings. However, the operator has also sent an update to the SIM to set the new PLMN to 22210 but this did not work: if I remove the PLMN from the LTE settings, I see in the logs that my SIM card still wants to connect to 22288 but access is obviously refused.
It’s not an issue per se, since if I keep the new PLMN, everything works fine, however I would like to know if the router can apply the OTA updates sent by the carrier to the SIM. If it does not, I will just insert the SIM card in a mobile phone for a few minutes.
Good question. IDK for sure.
RouterOS will check for firmware updates, but carrier updates are another thing. Those are handled by the modem. So it should - you’d want to do a hard power-cycle perhaps to be sure – since it be up to the modem/network how often it check. And just a /system/reboot may not be long enough “down time” for carrier think you’re just coming up (where modem/network often check).
But I’d just put in a phone to update. Similarly a reboot often speeds this up.
I think I had similar or same issue fiew years ago, MNO announced maintenance downtime at night (they didn’t specify what they are doing), next moring modem was unable to connect to network. Tried restart, nothing worked until I put SIM into MNO CPE router (luckily I kept it), when it was connected there I put back SIM into MT router and it also connected without any changes in ROS. So I’m guessing OTA update was applied in CPE router which was not handled by ROS.
