Je zoekt een GSM-poortopener module en elk resultaat is een productvermelding zonder context of een artikel over fysieke poortmotoren. Niemand vergelijkt de GSM-relaismodules naast elkaar. Deze gids doet dat wel.

## Wat is een GSM-poortopener module?

A GSM gate opener module is a small cellular relay controller that connects to your existing gate motor. It receives phone calls and SMS commands over the mobile network and closes a relay to trigger the gate. Unlike cloud-based smart gate systems, GSM modules work anywhere with cellular coverage, require no internet connection, and have no monthly subscription. According to manufacturer documentation, these modules support hundreds of authorized users and can be managed entirely via SMS.

## Veelgestelde vragen

### Can I mix different gate opener modules on the same property?

Yes. Each module operates independently with its own SIM. GateOpener manages multiple modules of different types from one app.

### Which module has the best 4G support?

Both offer 4G variants with similar European LTE band coverage (B1/B3/B5/B7/B8/B20). For US use, verify band compatibility with your carrier.

### Do I need a specific app for each module?

Manufacturer apps only work with their own hardware. GateOpener is the only app supporting both module families in one interface.

### Which module is most reliable?

Both use similar chipsets and relay hardware. Reliability depends on signal strength, power supply, and SIM health rather than brand.
