Yes, unfortunately 3g data does cost money. I am not very familiar with the Droid x but some phones have the ability to take a foriegn sim card. I have a feeling the Droid X does not. You can do almost anything on your phone on wifi for free, including making calls using google voice or text plus... both have the ability to text also. The only limitaition is being where you can get wifi. Beyond that, I am not certain what your options are without getting an international data plan through verizon (which are expensive for very little data).
