Please note that satellite telephones require a direct line of sight from the antenna to the satellite. Therefore, phones do not work inside buildings or vehicles unless used with an external antenna. Service in outdoor locations with trees, hills, mountains, buildings or other similar structures or geographical features may impair or prevent the use of satellite communication equipment.

Please note that text messaging service on satellite phones may not be possible to terrestrial mobile phones.
