Prepaid plans are mobile phone service options where customers pay for their usage in advance. This means you buy a set amount of minutes, texts, or data before using them, allowing you to control your spending. Once you use up your prepaid balance, you need to recharge or buy more credits to continue using the service. These plans are popular among those who want to avoid long-term contracts and monthly bills. They offer flexibility and can be a good choice for people who use their phones less frequently or want to manage their budget effectively. Many mobile carriers offer various prepaid plans to suit different needs.
