4G LTE GSM Access Control System for Gates, Garage Doors & Barriers
Looking for a GSM gate opener in Oman? The MHK 4G GSM Gate Opener Controller uses a SIM card inside the controller. That SIM has its own phone number (the GSM number). Call or send an SMS to that number from an authorized phone and the controller opens your gate, garage door, parking barrier, bollard or rolling shutter.
The controller works with a Nano SIM card on 4G LTE, 3G and GSM networks. When an authorized user calls, it rejects the call and activates the relay output on the first ring. That means no call charges and no remote controls, key fobs or access cards.
It is designed for residential villas, gated communities, commercial properties, warehouses, factories, farms, parking facilities and industrial sites in Muscat, Salalah, Sohar, Nizwa, Sur, Ibri, Rustaq, Barka and across Oman.
With support for up to 200 or 1200 authorized users depending on configuration, administrators can add or remove users through SMS commands. Caller ID verification blocks unauthorized numbers, and SMS confirmation of relay actions helps with monitoring.

How the MHK Controller Works
- Insert a Nano SIM card. Use an active SIM from an Oman provider. The SIM number is your gate's GSM number.
- Connect the antenna and power. Attach the included antenna and a power supply within the rated range (AC 9–30V or DC 9–36V, 1A).
- Wire the relay output to the start/open input of your gate motor or barrier control board. A wired switch can also be connected.
- Add authorized phone numbers using SMS commands, as described in the user manual.
- Call or SMS the GSM number. The controller checks the caller ID, rejects the call and opens the gate.

Frequently Asked Questions
What is a GSM number in a gate opener?
The GSM number is the phone number of the SIM card inside the controller. You call or send an SMS to this number from an authorized phone, and the controller opens the gate. Phones that are not authorized cannot trigger it.
How does the 4G GSM gate opener work?
Authorized users call the SIM card number installed in the controller. The device rejects the call and activates the relay to open the gate.
Are there any call charges?
No. The controller rejects the call automatically, so operation is free of call charges.
Which SIM card does it need?
It uses a Nano SIM (3V) from an Oman mobile provider, with coverage at your gate location. It supports GSM, 3G WCDMA and 4G LTE; the supported bands are listed above. If you are unsure about your network, message us on WhatsApp and we will confirm before you order.
Is the SIM card included?
No. The package does not include a SIM card. You need to provide your own Nano SIM and keep it active.
How many users can be stored?
Depending on the model, the controller supports up to 200 or 1200 authorized users. Administrators can add or remove users through SMS commands.
Can it control garage doors and barriers?
Yes. It is suitable for gates, garage doors, parking barriers, bollards, shutters and access control systems.
Does it support 4G LTE networks?
Yes. The controller supports GSM, 3G WCDMA and 4G LTE network communication.
What power supply does it need?
It runs on AC 9–30V or DC 9–36V at 1A.
Does it work during a power cut?
The controller needs power to operate. Whether your gate works during a power cut also depends on your gate motor and whether it has a backup battery.
Can I use it with my existing gate motor?
In most cases yes. If your gate motor or control board has a start, open or push-button input, the relay output (3A / 240V AC) can trigger it. Send us your gate motor brand and model on WhatsApp and we will confirm compatibility.
Is there a distance limit?
There is no fixed distance limit. You can control the gate from anywhere that has mobile network coverage, both at the controller and on your phone.
Do you deliver and install in Oman?
Yes. We deliver across Oman and offer professional installation with a 1-year warranty in Muscat and other areas. Cash on delivery is available.
