Common questions
Does my intercom need broadband?
A compatible cellular intercom uses the mobile network, so it does not need a fixed broadband connection for its SIM based features. Check the requirements of your particular device.
Can I open my gate by calling it?
Some GSM gate controllers support dial to open. This depends on the device and how it is configured; check your model before ordering.
Will this work with my existing equipment?
Compatibility depends on your device’s supported mobile technology, SIM format, calling requirements and local signal. Send us the make and model and we will help you check.
