Does the person I am calling need to have SkySipTel service too?
No. You can call anyone at any phone number using the SkySipTel service. Calls to other SkySipTel numbers are always free of charge. Indeed, some SkySipTel customers have saved thousands of dollars by purchasing two SkySipTel lines, one for themselves and another for their friend, relative, or remote business office.
