Prepaid Cards

If you are a seasonal user, on a fixed budget or aren’t concerned with having an ‘always on’ satellite service, prepaid cards are a great option. You’ll pay upfront, get great rates, and access Roadpost’s exclusive online tools designed to help you manage the valuable airtime you have paid for. Check out prepaid card options.

Postpaid Subscriptions

The convenience of uninterrupted service without having to manage usage, postpaid plans are ultimately flexible and hassle free. Because postpaid plans are ‘always on’ until cancelled, you’ll never run out of airtime. Whether you want satellite service for a month or forever, we offer competitive options to suit every need. You’ll pay a monthly service fee and receive detailed call records. Check out Iridium Phone Subscriptions.
