Whether you’re heading into remote backcountry terrain, crossing oceans, supporting field operations, or simply want peace of mind knowing you can call or text truly anywhere on Earth, our Iridium satellite phone monthly contracts deliver reliable, predictable global communication when you need it most.
Our flexible postpaid contracts are designed to suit a wide range of users, from occasional travellers and emergency back-up communicators to professionals who depend on voice and SMS connectivity as part of their daily workflow. With Iridium’s fully global satellite network powering these plans, you’re not limited by terrestrial coverage zones, you get service at the poles, in deserts, deep forests, or out at sea where other networks simply can’t reach.
Unlike prepaid top-ups that can expire or run out at inconvenient times, these monthly airtime contracts give you simple, recurring billing, clear inclusions, and the option to choose a plan that matches your usage requirements, from low-volume emergency check-ins to generous voice minute allowances for frequent calling.
Every plan includes:
-
Predictable monthly pricing with transparent billing
-
Global voice and SMS coverage across the Iridium network
-
The freedom to scale your plan up or down as your needs change
-
Peace of mind that you’ll stay connected where terrestrial mobile phones can’t
Whether you’re a solo adventurer, a fleet operator, or part of a large team deployed in remote environments, our Iridium monthly contracts make it easy to stay in touch without worrying about topping up balances or losing service mid-trip.

The Unlimited ISU-ISU Voice Add-On option is only available for Iridium Subscribers using SIM-based Iridium Handsets and is not available for use with L-Band Transceivers or the Iridium GO!®(“Non-Eligible Equipment”). There is no term commitment on the Unlimited ISU-ISU Voice Add-On option. Iridium will monitor SIM Card IDs/IMSIs and IMEIs on a monthly basis to determine if the Unlimited ISU-ISU Voice Add-On option is being activated and used on Non-Eligible Equipment. If Iridium determines that the Unlimited ISU-ISU Voice Add-On option is being activated and used on Non-Eligible Equipment, Iridium reserves the right to: (i) deactivate the Unlimited ISU-ISU Voice Add-On option on the Non-Eligible Equipment with immediate effect without any required notice, (ii) deactivate the Non-Eligible Equipment with immediate effect without any required notice, or combination of both. Voice calls between an ISU and Non-Eligible Equipment (i.e. Iridium 9555 to Iridium GO!) are not covered by the Unlimited ISU-ISU Voice Add-On option and will be charged at the Iridium to Iridium rate as per the Overage Rate Table.

Iridium-DSG Specific Terms
-
DSG plans are on an approval basis and require up to 7 working days to be created. Overage Charges for the three bundled and pooled voice call types (i.e., ISU-ISU, ISUPSTN, and ISU-Iridium VM), and ETF charges.
-
Under either the Starter 25, Advanced 100, or Power 250 plans, Iridium subscribers on the same plan may aggregate or “pool” their monthly bundled voice minutes (Iridium to Fixed/Cellular, Iridium to Iridium and Iridium to Voicemail) in a DSG (the“DSG Bundle”). For clarity, SMS-MO messages are not pooled. Each ISU participating in a DSG will be charged as per the rates in the Monthly Airtime Agreement Options. Each ISU’s voice usage of the three bundled call types (Iridium to Fixed/Cellular, Iridium to Iridium and Iridium to Voicemail) will be decremented against the DSG Bundle’s pooled voice minutes during the bill cycle until the pool is exhausted, at which point the Overage Rates as set forth in the Overage Rates Table apply. There is no rollover of bundled minutes as all voice minute allotments represent only the maximum usage without incurring additional charges or fees, not a required usage amount. As a result, there will be no minutes available for use or “rollover” at the end of the bill cycle. An ISU may only be included in a single DSG; however, the Starter 25, Advanced 100, or Power 250 Plans may each have more than one DSG created, subject to each DSG meeting the Minimum DSG Participants as set forth belowInsert and format text, links, and images here.
