Stephanie, thank you for your reply. But I am still confused from what you have written. You said that the Hawaii coverage is only for GSM phones - these are the phones that end with a "G". Then you say that it is only for phones that end with a "C", which is a CDMA phone. Now, which of these do you really mean? I have a "G'" phone right now, the Samsung T401G. Can I use that, or do I need to change phones to a "C" model?
