Without CloudTik
1) The unhappy customer calls because they have no connection.
2) You find out that the main connectivity went down 2 days before, and the SIM backup kicked in, but in the meantime, it has run out of data...
3)You give up and open a ticket, hoping they will fix it quickly while you recharge the data supply ceiling (if you can).
Eventually, the system is restored, but the customer is still dissatisfied 😡
