If you have the modem, and it's unlock to any network, you then can go to the provider shop (i think you can get it in every major shopping malls). For the sim, usually you will pay around 200-300 for a month. There is no quota, but the speed isn't that good.
be careful, make sure that you don't buy the CDMA based. Buy the GSM based such as Indosat M3, Three, Pro XL, Telkomsel. Indosat M3 is the most reliable one.
