For the first time I will have a Droid Worldphone with me when I travel to the DR. I have a prepaid Orange sim card to use in the phone. I am not sure if I know all of the steps to using the phone in the DR though. After I put minutes on the card I know I need to switch the phone to GSM and select the Orange network. I don't know if I need to do anything else though, or how to prepay for data.
