A 30-day or one-month SIM only deal works the same as a 12-month and 24-month SIM only deal – you’re just tied to the contract for a considerably shorter period. That means you’re free to ditch the deal at any point with just 30 days’ notice.
Aside from that, you still get an allowance for data, calls, and texts, just as you would with a longer SIM only deal. You don’t have to renew every month, either. The deal will continue to roll until you decide to cancel.
