Connor   Hi there. Update.   So, when using the multi-carrier SIMs, originally we weren't able to get them connected, the MG21 status page showed a connection to a network but WAN IP, no DNS and obviously no Meraki cloud visibility.    Had a call with our partner, had a play with the backend IP stack and allocation on our roaming SIMs, and all now working with just the APN, IP as 'ANY' and with no username and password. All ok.   What we are looking at now is the multi-carrier element to the SIM e.g. if say, a network mast was being work on by an engineer this could take down connectivity to that mast, so the 'multi-carrier' element would kick in.   In testing we tried to initiate this by forcing the SIM to use an alternate network (that had signal) to force over the carrier to use another. This was sort of working, but sometimes needed manual intervention or refreshing from the local status page. Further testing required. And ideally, we don't want to have keep asking end users to reboot the PoE injector for the MG as this isn't practical nor wanted.   What would be good, and I have heard of mention of scripting within the MG21 to auto reboot if a signal is lost (but not found this yet), which would be one thing, but it would be amazing if there was better control of the MGs to do things e.g. reboot, like we can with APs etc, but as the WAN ports of the MXs aren't PoE, this can't be managed via the dashboard to 'shut' and 'reopen' that port to force an MG21 to power cycle if the MG21 had lost cellular connectivity like we could if one a switch?   Anyway, for the forum and interest, I will update you once I know the best format.   Cheers    A   ...

Connor   Yes, that is correct, it is a multi-network SIM looking for the best signal.   We have always used specific provider SIMs in the past but with multiple geo deployments sometimes the signal maybe poor with one provider and to try and alleviate this with the first hit and not have to revisit for an alternate SIM provider, we have now got a multi-roaming SIMs with a specific business APN (non-consumer SIM).   Thank you    Adam   ...

Connor   Thank you for your reply.   We have a specific APN (no username and password required), and should be 'ANY' IP also, for which should give us a dedicated IP per SIM ICCID from our provider in this case.   We have tried using differing options regarding the settings, which in this case is a 'Roaming SIM', and when connecting the MG is trying to find the best signal, so in this case looking for a 'Vodafone' connection, but won't connect.   I think the issue we have is the 'Roaming' element on the Meraki MG21 as the SIM is looking for the best signal but isn't able to perhaps roam properly to enable our connection.   I have seen some other 'Roaming' queries on the Meraki Community as well, but no answers there.   Thank you    Adam   ...

Connor   Interesting and good stuff.   May I ask, if you were adding this info to the MG21, but your ISP was giving you your own subsidiary of an o2 or Voda APN, so you would have a static IP for instance and you knew it. Has this been entered or tried?    Or, if it is an 'ANY IP' setting and that the ISP gave you a static IP in the same fashion as above, can it be left as 'ANY IP' but would retain the same IP from the provider e.g. a static one as per their provided APN?   Just wondering if it is a 'Merakism' with this menu option or it just doesn't like a static IP for cellular configuration even if provided one by the SIM provider?   Thank you    Adam ...
