I'm in the Navy getting ready to deploy for 6 months and I need to get an international calling plan so I can keep in touch with my family at home. I will be traveling around the western Pacific (Asia, Australia etc) for approximately 6 months. I do have Vonage and I see that they have an international plan for an extra $15, is it worth it? I would prefer to use a cell phone if possible so I don't have to wait in line for a phone so I would like to find an inexpensive cellphone plan if one is reliable enough. Thanks for your help.
