4G VoLTE Intercoms

For Electric Gates and Doors

Our 4G VoLTE Intercom has been tested to offer 4G calls and SMS on the following networks

  • 3 UK
  • EE UK
  • Vodafone UK (native network only)
  • Vodafone Germany
  • Vodafone Ireland
  • Bouygues Telecom France

Without VoLTE your intercom will drop back to 2G and 3G for calls and SMS. We expect 2G and 3G voice networks to be shut down in Europe by 2026 meaning only VoLTE tested intercoms will work beyond this date.

The 4G VoLTE intercom is available in a range of colours and finishes designed to compliment your electric gate installation.

  • Entensive Colour Range
  • Slim Design (Just 2cm thick)
  • High Quality Materials
  • Any Mobile Network (including 3)

Cellular technology is a complicated business but we've made installation and programming easy with our voice assistance and simple commands. To simplify the physical installation, all iDG intercoms feature an internal aerial to avoid additional cabling and brackets.
