What Are The Running Costs Of Satellite Phones? Satellite phones are ideal for anyone needing voice and SMS capabilities in areas where no other reliable methods of telecommunications are available. You have a choice of two airtime options when buying a satellite phone; pay-as you-go or a pay monthly contract. If you plan to use your satellite phone regularly throughout the year and do not want to worry about the expiry dates or inconvenience of topping-up pay-as-you-go SIM cards you may find it more convenient and cost effective to use a post-paid SIM card.
