I will be going to aruba and I am trying to decide if I am better off paying verizon the extra $ to use my droid or just put the droid in airplane mode and use wifi. I don't really think I will need to use the phone, but perhaps text messages, and to check emails etc. I have heard that I can just use google voice to send free sms, is this true? I have also read that I can not use google voice to make free calls while in aruba, is this true? Thanks so much for your input!!!
