Important Considerations:

  • **Network Coverage:** Iridium offers truly global, pole-to-pole coverage due to its low-earth orbit (LEO) satellite constellation. Inmarsat uses geostationary satellites, providing near-global coverage but with potential limitations at extreme latitudes.
  • **Purpose:** The Iridium 9555, 9575, and IsatPhone 2 are primarily satellite phones for direct voice communication. The Iridium GO! is a hotspot device that allows your existing smartphone or tablet to connect to the satellite network for calls, messaging, and basic data.
  • **Durability:** All models are built to be rugged, but the Iridium 9575 Extreme and Iridium GO! have military-grade durability (MIL-STD 810F).
  • **Features:** The Iridium 9575 Extreme and IsatPhone 2 include dedicated SOS/assistance buttons and GPS tracking, which are crucial for safety in remote areas. The Iridium GO! excels at providing connectivity to multiple devices simultaneously.
  • **Battery Life:** The IsatPhone 2 boasts significantly longer talk and standby times compared to the Iridium phones.
