I recently purchased a MX68CW and when I contacted my cellular provider, Verizon, to purchase a SIM card, they informed me that the MX68CW will not work with a Verizon SIM. Does anyone know when Cisco and Verizon will be able to resolve this problem? Otherwise I am unable to use the cellular backup feature of the Meraki router unless I open a new account with AT&T or other cellular provider.
