When you have a postpaid connection on mobile (or anything else), you consume the data in credits and pay later on whatever bill you get. So, you are never sure whether the payment will be within your budget or not. The way to get rid of this problem is to go towards prepaid.
Prepaid is like debit; you pay as per your budget. You can also get an unlimited prepaid plan that lets you enjoy more features than postpaid at a much lower cost.
