Frequently Asked Questions

Q: Does the RTU5024 GSM door opener work with any SIM card?

A: The RTU5024 supports any standard 3V GSM SIM card from a carrier operating on the 850, 900, 1800, or 1900MHz bands. It is compatible with the global GSM 4G network, so it works with most carriers worldwide. Simply insert an active SIM card with SMS capability to get started.

Q: How many users can I authorize on the RTU5024 relay?

A: The RTU5024 GSM access control relay supports up to 200 authorized phone numbers. You can add or remove numbers at any time using simple SMS text commands, giving you complete flexibility for homes, businesses, or shared access points.

Q: Is there a monthly subscription or ongoing cost to operate this wireless door opener?

A: No subscription is required. The device uses your SIM card's standard plan. The relay activates on the first ring of an incoming call, so the caller is never connected and incurs no call charge. You only pay for any SMS confirmations sent by the device, which depends on your carrier's SMS rates.

Q: Can I control the relay closing/opening duration?

A: Yes. The relay timing is fully programmable via SMS commands, allowing you to set how long the relay stays open or closed to suit your specific gate, garage door, barrier, or machine application.

Q: What is the difference between the US Plug and EU Plug versions?

A: Both versions include a 12V power adapter and are functionally identical. The only difference is the plug shape — the US plug version suits North American outlets while the EU plug version fits standard European-style sockets. Select the version appropriate for your country when ordering.
