I have learned a lot about international phone services. I started with Mytello but was unable to understand what to do or use the system other then a plan. I didn't know I could load a prepaid card (I believe that is the correct term). So because of my lack of understanding I went to another service and was sorely disappointed. I didn't connect at all 0 for 47 tries in one day. Thank God I went back to Kytello, sure it isn't perfect but I hit 80 to 85% of completed called. So yes this is the best of all the choices. The best of all is how clear the call is, most impressive.
