Postpaid is a method where you pay your phone bills after using it. Whereas in prepaid, you already pay for a fixed amount of calls or days. Both have their advantages. If you use a lot of data and call a lot, you are better off with a postpaid plan, as usually pre-paid plans don’t have large data caps. However, if you prefer to limit your data usage and save money on it, prepaid is the way to go.
