Yes, you're correct about that. However, if you're on the road and have an emergency, then your wifi won't help you. That's why we purchased a sim card from Sharon and put it in our phone when we arrive on the island. You can get them now at the UTS store which is in the same shopping area with IZI restaurant. The people there are very helpful (but they're not Sharon <img src="http://www.traveltalkonline.com/forums/images/graemlins/Sad.gif" alt="" />)
