The link was broken https://documentation.meraki.com/MG/MG21%2F%2F21E_Datasheet I have not done an MG21 in Ireland with Vodafone, but here is what I would offer a some steps to try. 1) Verify the SIM is active and works in another device (Mobile phone, another Meraki device, or USB modem) 2) Make sure you can get signal on a mobile phone on Vodafone where the MG is deployed 3) Verify if there is any special APN settings needed for the carrier ( I know Verizon static IP is this way in the US) 4) Verify the MG has connected to the Meraki cloud and got a firmware update (May need to be wired to do this) 5) Check the local status page of the MG and see if you are getting signal, if not its a signal issue, if so config issue.
