Bulk SMS software download: the Ultra SMS free trial

The free trial needs no purchase and no sign-up: install, use every feature, and send 25 SMS a day. Add a licence key later to remove the limit. One key covers 1 device on Starter, 3 on Business, 10 on Agency. Current version 1.0.0.

  • Windows

    Windows 10 or 11, 64-bit

    If Windows says "Windows protected your PC", click More info, then Run anyway. The installer is new and not code-signed yet.

    Download UltraSMS-Setup.exe

  • macOS (Apple Silicon)

    macOS 12 or later

    Needs a Mac edition key (the free trial works without one). Open the .dmg and drag Ultra SMS into Applications. The first time you open it, macOS says it cannot check the app: click Done, open System Settings, Privacy & Security, scroll down and click Open Anyway. On macOS 14 or older you can instead right-click the app and choose Open.

    Download UltraSMS-1.0.0-arm64.dmg

  • macOS (Intel)

    macOS 12 or later

    Same steps as Apple Silicon. Not sure which Mac you have? Apple menu, About This Mac: "Apple M" means Apple Silicon, "Intel" means this one.

    Download UltraSMS-1.0.0-x64.dmg

  • Linux

    64-bit Linux with a desktop

    Make it executable with chmod +x UltraSMS-*.AppImage, then run it.

  • Android

    A recent Android phone or tablet

    Open the downloaded file and allow installs from this source when Android asks. Activate it with the same key: it counts as one of the devices your tier allows.
