@BrianWa_1755075 Do you have them on one Group account or on two separate accounts?
Group - if you no longer renew the smarty plan for the data only sim then you will receive a 'warning' email after 180 days and the sim will be deactivated after a further 40 days.
Individual - same process - do not allow auto-renew for the data only sim. In this case, you would need to log into the individual account to do that.
