This has to do with the expiration of the SIM. Generally, most prepaid SIM cards expire after a certain period of inactivity, or a certain time after the last addition of credit to the account. Sometimes this can be very generous (most British SIMs require just one billable action from anywhere at least every six months or one year to stay active), so as long as you are able to meet the provider's guidelines, the SIM will indeed be available for use on a later trip. Often the expiration date for being able to receive calls on the account will be longer than that for being able to place calls.

Note that pretty much everywhere outside North America, you do not pay to receive calls ever, unless you are roaming in another country.
