Cosmo Communicator (SIM Free / UK)

Following the success of the original Gemini PDA, Planet Computers are developing the next generation of the product: the Cosmo Communicator.

Feedback from Gemini customers has been well received and the Cosmo will have several new features suggested by the community. These include:

  • External colour display for caller information
  • Backlit keyboard
  • External 24MP camera
  • Fingerprint sensor
  • Improved call handling
  • NFC, updated 4G modem, increased memory

The core design of the device remains mostly unchanged, being a clamshell device with 5.99-inch touchscreen display, full 4-row QWERTY keyboard and up to date Android installation with additional productivity apps.

There will also be support for the Linux-based Sailfish OS, which may be preinstalled, plus Debian Linux and other selected distros.

Indiegogo crowdfunding

As of January 2019, Planet Computers have secured over 1 million US Dollars in funding towards the production of the Cosmo Communicator through their Indiegogo crowdfunding page. Early orders can still be placed through the Indiegogo page at the discounted rates.

Planet Computers aim to ship the first Cosmo units in May 2019. Clove Technology will have retail stock soon after this.
