A million dollar question in users mind is where should i go for postpaid or prepaid?. I would give some advantage and disadvantage of both sides that helps you to take decision.
Postpaid mobile connection is like any other telephone connection, where you get a SIM Card, use it and pay for your monthly mobile bill based on rentals, plan charges and usage charges etc.
Prepaid mobile plans are plans where you have to purchase first for mobile phone credits before you could use their services.
In case of Prepaid plans you don't need to wait for approvals of any applications. You just need to buy a prepaid credit, then you could easily use your mobile phone without any hassles.
on the other hand Postpaid plans requires you to submit some legal documents like address proof, Identity proof etc.
Prepaid mobile plans restrict you to make unnecessary calls because of limited amount of balance.
In postpaid mobile plans where you could make all the calls you want (if your plan don’t have a limit), there's nothing to stop you. So comparatively prepaid mobile plans would prove to be a economical.
When your mobile phone gets lost in case of postpaid, the serial number is registered with your mobile service provider. With the help of this unique serial number of your mobile phone they either block it or trace it easily. Where as in case of prepaid mobile phone its not possible to trace.
In terms of rates, prepaid mobile plans would be more economical but postpaid mobile plans offers a much lower rates.
if you use mobile services in control manner, postpaid mobile plans would be the best choice. But if you misused because it has no limit, I suggest you to purchase prepaid plan. one major drawback with postpaid mobile plans require you to pay minimum mobile bill (rental) even if you didn’t make any call.
