Which is the best Inmarsat Plan for you?

Comparing the Inmarsat Standard and Inmarsat Flex Plans:

  • Activation Fee: The Inmarsat Standard plan has a one-off $25.00 activation fee. The Inmarsat Flex plan offers the option for a 3 month minimum term, rather than 12 months when you pay a $50 activation fee. Please note if you choose to pay a $50 activation fee there is no minimum term. Minimum cost will be one month's access fee + $50 activation fee. 
  • Anytime SIM Suspension: At any point during your contract you can suspend your SIM and reduce monthly payments to only $5 per month on the Inmarsat Flex Plan. There is no option to suspend your plan on the Inmarsat Standard plan. 
  • Dedicated Local Number: Customers signed up to the Inmarsat Flex Plan will be assigned a dedicated US or UK phone number and a SIM card free of charge. This results in much lower calling charges, as calls to the handset will charge at the same rate as the network rate, rather than the Satellite Phone rate. Inmarsat Flex customers must select their preference to a US or UK phone number, when completing the pay monthly contract. Customers on the Inmarsat Standard Plan do not have this option.

Basic and Professional Mapping plans

The Basic mapping plan is available from just £6.50 a month per device and provides location-based data from your device to the online maps. The tracking equipment determines its location by triangulating a position using GPS (Global Positioning System) and then transmits this information via GSM, Satellite, or VHF to a central server for processing. Alternatively, the Professional mapping plan is available from just £12.50 a month per device and allows you to track multiple devices on the same map! This plan is essential for businesses or organisers managing multiple devices to be able to track the movements of individuals and assets. Find out more.
