Iridium Edge® 9603 Satellite Modem


The Iridium Edge® allows you to send and receive short messages from anywhere on Earth, so long as you have a clear view of the sky. It works far beyond the reach of Wi-Fi and GSM networks.

Maybe you want to transmit weather information from mid-ocean? Or use it to get telemetry back from an oil well? Perhaps you need to communicate in an emergency, when other networks might not be available? Whatever you need it for, we can help.

Combined with our flexible data packages and RockBLOCK IoT platform, you can connect your remote systems seamlessly.

RockBLOCK+ vs. Iridium Edge

Our RockBLOCK+ product is very similar to the Iridium Edge. There are some key differences, though, which may guide your choice, and these are illustrated in the table below.

Both the Iridium Edge and our RockBLOCK+ unit come with access to our ‘Core’ management system, so you can receive data via HTTP POST, easily see message traffic and diagnose issues, and manage your airtime usage quickly and easily online.

Running Costs

Line rental is paid in blocks of 1 month, and allows the Iridium Edge to exchange information with the Iridium satellite network. You only pay for months in which you wish to use the Iridium Edge. No annual contract is required. Line rental costs $16 / £12 per month and includes access to The CORE management system for managing your devices.

Credits are used each time you transmit. 1 credit is used per 50 bytes (or part thereof) of message sent or received. 1 credit is also used if you check your mailbox and there are no messages waiting (A mailbox check). Credits do not expire unless you do not use your account at all for 12 months. Credits are shared/pooled between all of the devices on your account

Please note, while our pay-as-you-go tariffs offer great flexibility for development purposes, we know they are not suitable for everyone. If you are planning a large deployment of devices (100+) and are willing to commit to airtime contracts of 12 months or more, please get in touch. We have access to various tariffs which may suit you better.
