Whether your farm is 80 kilometres outside Lahore, your factory is across the city, or your second home in Murree sits empty most of the year, you cannot be everywhere at once. You can, however, be notified the instant something happens.
While the WiFi Gateway connects your fence to an app, the Nemtek GSM Module takes a different approach: it uses a SIM card to send SMS text messages directly to your phone. No internet, no app, and no WiFi are required. For many properties in Pakistan, this makes the GSM Module an essential security tool.
What Is the Nemtek GSM Module?
The Nemtek GSM Module is an add-on device that allows your energizer to communicate over the cellular network. Once a SIM card is installed, it sends clear text alerts to pre-programmed phone numbers when specific events occur.
It works independently of your home internet. In Pakistan, where networks like Jazz, Zong, Telenor, and Ufone cover even rural areas, the GSM Module stays functional in locations where WiFi is not an option.
What Triggers an SMS Alert?
The module can be configured to notify you for several critical events:
- Intrusion Alarm: The most important alert. It tells you someone has touched or cut the wire right now.
- Mains Power Failure: You are notified immediately when the fence switches to battery backup due to load shedding.
- Battery Low Warning: An early warning to recharge or check the system before protection lapses.
- Fence Fault: Notifies you of technical issues like wire breaks or short circuits before they become security risks.
- Arm/Disarm Confirmation: Provides a record of exactly when the fence was activated or deactivated.
Why the GSM Module is Valuable in Pakistan
1. Remote and Rural Properties
Many agricultural plots, orchards, and industrial units outside major cities lack reliable internet. As long as there is a mobile signal, the GSM Module ensures you are never out of touch with your property’s security.
2. Backup for Urban Homes
Even if you use a WiFi Gateway, the GSM Module adds a layer of redundancy. If your internet router resets during load shedding or your ISP has an outage, the WiFi app will stop working. The GSM Module continues to send SMS alerts regardless.
3. No Smartphone Required
SMS alerts arrive on any mobile phone, including basic handsets. This is ideal for property owners who prefer simplicity or for security staff on-site who may not use smartphones.

Frequently Asked Questions (FAQ)
Which networks work with the GSM Module?
It works with any standard GSM SIM—Jazz, Zong, Telenor, or Ufone. We recommend choosing the network with the strongest signal at your specific location.
What happens during load shedding?
The GSM Module runs on the energizer’s battery backup. In fact, it will send you a text message the moment the power goes out so you aren’t left in the dark about your system’s status.

Yes. If you have a compatible Nemtek energizer, our team can visit your property to install and configure the GSM Module as a standalone upgrade.
