Each has restrictions that define the service. Make sure you understand those restrictions before you make a long distance call. The wireless phone industry has matured very quickly, and the wireless phone companies are offering various service plans that may be right for you. If you only make a few long distance calls a month, consider not subscribing to a long distance carrier and using only 10-10 numbers or a calling card. Look for a carrier with no monthly fee and low per minute charges.
Some long distance calling plans are beneficial too.
If you decide not to subscribe to a long distance carrier, call your local phone company and tell them you do not want to subscribe to any long distance provider.
