GSM Phone Entry Systems
Open your gate from anywhere using a standard phone call or text message — no internet required. GSM gate openers use the mobile network and are the most reliable access method for London properties with poor WiFi at the gate.

A GSM gate opener is one of the most practically useful access control additions you can make to an automated gate. The device fits inside or alongside your gate motor, contains a SIM card, and opens the gate when it receives a call or text from an authorised mobile number. No internet connection, no app, no WiFi at the gate post — just a phone call.
The system works on a whitelist of authorised numbers. You add the phone numbers of people who are allowed to open the gate. When they call the GSM unit, it recognises their number, opens the gate, and hangs up. The caller is never charged because the call does not connect in the conventional sense — the system identifies the caller ID and rejects the call while triggering the gate. Some units also accept text commands, useful for adding or removing users remotely.
GSM systems are particularly popular for London properties where the gate post is far from the house and running a stable data connection to the post is impractical, for holiday homes where reliable gate opening from a distance is needed, and as a backup access method alongside a primary video intercom. Most units run on a pay-as-you-go SIM with minimal monthly data usage.
Why Choose GSM Phone Entry Systems
Works Without Internet
GSM gate openers use the mobile network, not WiFi. No router, no cables, no data connection at the gate post. If you have a mobile signal, the gate opens.
Free to Call From Your Phone
The gate opener identifies your caller ID and rejects the call before it connects. You are never charged for the call, and neither is the gate SIM billed for incoming calls.
Whitelist Up to 1,000 Numbers
Add or remove authorised numbers by text message from the admin phone. No app, no computer, no engineer visit required. Manage access from anywhere instantly.
Reliable Backup Access
Pair a GSM unit with your primary video intercom or keypad as a backup. If WiFi fails, the gate can always be opened via phone call.
