It does not depend on how you pay (cash or credit card). You are either on a default rate per MB or have booked a data (or combo) bundle. On a bundle (also called package) you have a certain allowance that is sold much cheaper than their by-MB rate.

For more info about bundles check here: Data on SIM cards

So first buy a SIM, top it up and avoid using data. Then activate a bundle/package and use data.
