Frequently Asked Questions

Q: How does the GSM Gate Door Opener Relay Switch work?

A: The GSM Gate Door Opener Relay Switch uses a standard GSM SIM card to receive incoming calls. When an authorized phone number calls the device, it rejects the call (at no charge to the caller) and simultaneously triggers the relay to open or close your gate or door. No internet connection is needed — it works anywhere with GSM network coverage.

Q: Can multiple users control the GSM Gate Opener?

A: Yes. You can program multiple authorized phone numbers into the controller, allowing family members, employees, or trusted guests to operate the gate or door independently using their own mobile phones.

Q: Is the relay open/close timing adjustable on this GSM controller?

A: Absolutely. The relay close and open duration is fully programmable, so you can fine-tune exactly how long the gate or door stays activated with each trigger — ideal for different types of gates, locks, or barriers.

Q: What GSM network bands does this relay switch support?

A: This controller supports 850, 900, 1800, and 1900 MHz GSM bands, making it compatible with the vast majority of GSM SIM cards and mobile networks worldwide.
