How much does it cost to send messages with the Sentinel?
Message costs depend upon the LES you use and the mode of transmission. Messages can be sent mobile to mobile, telex delivery, to a mailbox at the LES for PSTN delivery or to a fax destination (in the case of ship to shore only). You should contact the LES you plan to use to get precise pricing. In general, message costs are approximately US $0.008 per character with a 128 character minimum. Messages sent in the telex mode are more expensive.
