Fleet Broadband provides IP Internet access, as well as switched telephone connections to the public switched telephone network (PSTN). Voice calls are billed at a cost of about $1 per minute, depending on your service contract. The terminals come equipped with an IP telephone that can be used for voice calls and SMS messaging.

Data usage is billed by the megabyte. On the two larger terminals one can choose between a contended (shared) bandwidth that is always available like a regular internet connection, or guaranteed, "streaming" bandwidth on demand, for transfer of critical data.
