I have a Kyocera Duraxv Extreme and I want to use it in Israel. I heard that there's a service called Tripletel that is compatible. Does anyone know more about this? Is it good clear service? Does data work well? Do I have to do any sort of unlocking of my phone to make it work or can I just buy I SIM card and put it in? If there's anything else I need to know plz tell me. Thanx.
