The Iridium Extreme PTT combines global satellite phone functionality with instant push-to-talk communications in one rugged handset. Designed for remote teams, emergency services, maritime crews and field operations, it delivers secure one-to-one and group communications anywhere on Earth without relying on mobile networks or radio infrastructure.

Built for demanding environments, it features MIL-STD 810F durability, IP65 protection, integrated GPS, a programmable SOS button and AES-256 encryption. Administrators can also manage users, talkgroups and coverage areas through the Iridium PTT Command Center.

The Iridium Extreme PTT is a rugged, dual-mode satellite communications device designed for teams working in remote, high-risk or infrastructure-free environments.

Combining traditional satellite phone functionality with instant push-to-talk communications, it enables secure one-to-one and one-to-many voice communication anywhere on the planet using the Iridium satellite network.

Unlike conventional radio systems, it does not depend on local repeaters, mobile coverage or terrestrial infrastructure. This makes it ideal for emergency response teams, security operations, utilities, maritime crews, expedition leaders, remote workers and government organisations.

Satellite Phone and Push-to-Talk in One Device

The handset can switch between two operating modes depending on the situation.

In satellite phone mode, users can:

  • Make and receive voice calls

  • Send SMS messages

  • Access GPS and location-based services

  • Use the handset like a conventional Iridium satellite phone

In push-to-talk mode, the device operates like a satellite walkie-talkie, allowing users to communicate instantly with individuals or entire teams across wide geographic areas.

Designed for Demanding Environments

The Iridium Extreme PTT is engineered for harsh conditions and intensive field use.

It carries MIL-STD 810F certification and an IP65 rating for dust and water resistance, helping it withstand rain, shock, vibration, dust and extreme operating conditions.

A reinforced push-to-talk button, weather-resistant keypad, high-gain antenna and powerful loudspeaker also make the handset easier to use in noisy or challenging outdoor environments.

Secure Communications and Location Services

The platform supports AES-256 encryption to help protect sensitive voice communications and operational information.

Integrated GPS functionality also enables location tracking, check-ins and mapping services, while the programmable SOS button provides an additional layer of emergency support for users operating in isolated areas.

Centralised Team Management

The Iridium PTT Command Center gives administrators control over the entire communications network through a web-based platform.

Administrators can:

  • Create and manage talkgroups

  • Add or remove users

  • Define geographic coverage areas

  • Adjust permissions

  • Make operational changes in real time

This makes the platform suitable for organisations managing teams across multiple regions, countries or operating areas.

Battery Performance

In PTT mode, the handset provides:

  • Up to 5 hours of talk time

  • Up to 16.5 hours of standby time

Battery performance may be extended further when the device is used in standard satellite phone mode, depending on usage and operating conditions.

Ideal Applications

The Iridium Extreme PTT is well suited to:

  • Emergency response and disaster recovery

  • Offshore and maritime operations

  • Security and defence deployments

  • Lone worker communications

  • Utilities and infrastructure maintenance

  • Mining, oil and gas operations

  • Humanitarian and NGO field teams

  • Expeditions and remote exploration

For organisations that need secure, dependable and truly global team communications without relying on terrestrial infrastructure, the Iridium Extreme PTT provides a powerful satellite push-to-talk solution.
