Prepaid phones are mobile devices that allow users to pay for their service in advance, rather than signing a long-term contract. This means customers can purchase a specific amount of talk time, text messages, or data, which they can use until it runs out. Once the balance is depleted, users can simply add more funds as needed. These phones are often popular among those who want to control their spending or avoid credit checks. Many major carriers, such as Verizon and AT&T, offer prepaid plans, making it easy for users to find options that suit their needs without commitment.
