A prepaid phone plan is a type of mobile service where customers pay for their phone usage in advance. This means you buy a specific amount of data, talk time, and text messages before using them. Once you use up your balance, you need to recharge or buy a new plan to continue using the service. These plans are popular because they offer flexibility and control over spending. Users can choose from various options, such as monthly plans or pay-as-you-go plans, without being tied to a long-term contract. This makes them ideal for those who want to avoid unexpected charges.
