Do I have to pay the plan’s price every month in order to be able to use the plan along with the active SIM fee or just pay the plan’s price when it all of it has been used up and pay only the active SIM fee?
Renewing the plan is optional. If you do not renew, you will switch to PAYG. The monthly fee is charged for all active SIMs for all plans. For more details about prices, please check the https://connect.sixfab.com/#/pricing page.
