Property owners frustrated with constant offline errors frequently ask: “Can a gate opener use multiple networks?”
The answer is yes. You do not need to buy a complicated new intercom or a dual-SIM hardware module to achieve this. You simply need to upgrade the “brain” of the connectivity—the SIM card itself.
How to Make Your Gate Multi-Network
Most GSM gate modules and 4G intercom routers contain a single standard SIM slot. If you put a consumer EE SIM into it, the gate can only use the EE network.
To make the gate use multiple networks, you remove the standard SIM and insert an Anywhere SIM Multi-Network Roaming Card.
The Unsteered Failover Process
Once our SIM is installed, your existing gate hardware gains the ability to “roam” domestically across the UK.
- Scanning: The gate module powers on and the SIM scans all available local frequencies from EE, O2, Vodafone, and Three.
- Primary Connection: It connects to the absolute strongest, most stable mast (e.g., O2).
- Automatic Redundancy: If the O2 mast suffers an outage, or the signal drops due to bad weather, the SIM instantly instructs the gate module to switch. It seamlessly reconnects to the next strongest network (e.g., Vodafone).
Why This is Essential for Installers
For gate automation installers, returning to a site to fix a “broken” gate, only to discover the issue is simply a local Vodafone network outage, is a massive drain on time and profit.
By installing an Anywhere SIM as standard, you guarantee your clients 99.9% uptime. The gate will dynamically adapt to the cellular environment, providing failsafe access control without requiring any user intervention or expensive dual-SIM hardware.
