Iridium Core 9523 is Iridium's smallest, lightest and most advanced voice and data satellite transceiver module ever, enabling simplified global voice and data connectivity through the world's furthest reaching network.


Pushing the boundaries of global communications

The Iridium® Core 9523 advanced voice and data satellite transceiver module is small, light and powerful. Its compact footprint and simple connections offer our partners new opportunities to integrate Iridium directly on their printed circuit boards (PCB) and develop products that meet the needs of previously unreached consumer and vertical markets like never before.

Powering new possibilities

From single or multi channel communication platforms for maritime, aviation and land mobile markets to highly capable feature enhanced handheld smart devices and unattended sensors, Iridium Core 9523 delivers cost effective satellite voice and data communications .

Enabling new capabilities

Small but powerful, Iridium Core 9523 supports all Iridium voice and data services. One tiny module delivers the capability needed to develop innovative communications devices, and the technology backbone for embedded applications such as GPS and location-based services (LBS), Wi-Fi and Bluetooth.

Simplifying integration

Iridium Core 9523 features standardized connectors, making integration into innovative new devices and solutions easier than ever. With simplified PCB integration and compact form factor, designers can mount Iridium Core 9523 directly onto their application board − enabling optimization through shared components and power sources.

1 Month Contract Term
For SBD, 1 KB = 1,000 Bytes, 1 MB = 1,000 KB and 1 GB = 1,000 MB
Devices may be suspended for up to 24 months for $3/month.
For large fleet or anticipated monthly usage of more than 1 MB please contact us for customized plan. 1.305.633.9636


SBD Mailbox Check

Mailbox check is charged when the device sends a 0 byte message to check if there is a message queued at the gateway. These messages are free as long as there is a message queued at the gateway. If the gateway does not have a message queued, there is a $0.05 charge for each check.


SBD Registration

Each device can register on the network once a month. Additional registration events are charged at $0.05 each.
