Which services are typically not offered by INMARSAT-B?

INMARSAT-B is designed primarily for providing reliable voice and data services to users in maritime, aviation, and land mobile environments. While it offers services like text messaging, fax communications, and general telephone communication, free internet access is not one of the services provided.

The reason that free internet access is not included is due to the nature of satellite communication services, which typically require users to pay for bandwidth and data usage. INMARSAT services are structured around usage-based billing, so while they facilitate internet access, it comes with associated costs rather than being offered for free. This billing structure is essential for managing the operational costs of maintaining satellite infrastructure and delivering the services.
