A SIM card with prepaid minutes is a convenient mobile phone solution that combines a Subscriber Identity Module (SIM) card with a preloaded balance of call time, texts, or data. Users purchase a set amount of usage in advance and can use these minutes until they run out. Once the prepaid balance is depleted, users need to buy more minutes to continue using the service. This system offers flexibility and control over mobile expenses, as there are no monthly bills or long-term contracts. It is ideal for budget-conscious users and those who prefer a pay-as-you-go approach to mobile phone usage.
