A postpaid phone plan is a type of mobile service agreement where customers pay for their usage at the end of each billing cycle. This means users receive a monthly bill that includes charges for calls, texts, and data used during that period. Postpaid plans often come with a contract, typically lasting one to two years, and may include a subsidized phone. These plans usually offer more extensive features compared to prepaid options, such as higher data limits and additional perks like international roaming. Customers often enjoy the convenience of not having to recharge their accounts frequently, making postpaid phones a popular choice for many users.
