Hello, C's Phones on middle street rents phones. I would think its not too much, ahhh say maybe 30 bucks or so for a week and a very nice selection for sure. Deposit shouldnt be too bad as long as it covers the cost of the phone ,like say if you were to drop it in the ocean Etc, depending on what make model you rent will depend on deposit I would say. Youll buy pre paid phone cards to charge your phone which are sold around the island in misc bars and restaraunts, with minuts which you could use to call any where in the world if need be. Have fun!
