The Motorola Defy Satellite Link introduced many to the concept of turning any phone into a satellite messenger. However, if your primary need is simply pulling off-grid weather forecasts, there's a more streamlined way that doesn't require extra hardware or monthly contracts.
While the Motorola Defy Satellite Link (which operated on the Bullitt Satellite Messenger network) was an innovative Bluetooth accessory, the landscape of satellite communication has shifted rapidly. Today, modern smartphones have satellite modems built directly into them.
SMS Weather On Demand is engineered to take advantage of this new reality. Instead of managing the battery life of a separate Bluetooth dongle and paying monthly subscription fees just to keep the service active, you can use your phone's native satellite texting capabilities (like those found on iOS 18+ or Android 15+) to request weather forecasts directly.
Our service is entirely independent and pay-as-you-go. You only pay for the exact weather forecasts you request. No hardware to charge, no firmware to update, and no monthly commitments.
Test it for yourself—your first requests are on us!
The initial setup happens while you're online, so that you're ready to go when you're off the grid.
Create an account to verify your phone number. Then use the "Add to Home Screen" feature on your phone to install and run our lightweight application so it can be used offline.
Head out even where there's no internet. As long as your phone has the capability to send texts or use satellite messaging, you're covered.
Open the app from your home screen. It uses your GPS location and your selected forecast options to help prepare a unique text for your request.
Just hit 'send' in your messaging app. You'll get a weather forecast texted back in moments.
Please note: Standard messaging rates from your cellular or satellite carrier will apply for the SMS messages you send and receive. Coverage and Deliverability are also dependent on the cellular/satellite messaging providers you use.






No! SMS Weather On Demand is designed to work directly with your smartphone's native satellite messaging features, eliminating the need for a separate Motorola Defy Satellite Link or any other Bluetooth accessory.
Unlike the recurring plans associated with many hardware communicators, SMS Weather On Demand operates entirely on a pay-as-you-go model. You are never billed when you aren't using the service.
Extremely accurate. By parsing your exact GPS coordinates sent via SMS, we query highly localized weather models to deliver a forecast tailored specifically for your exact latitude, longitude, and elevation.
Drop the extra device and the monthly fees. Create your account and try SMS Weather On Demand for free.
