Description
Justworx IoT SIM Card V2.0
The Justworx IoT SIM Card V2.0 is designed for low data-consuming IoT and security devices that require reliable, long-term mobile connectivity without contracts or monthly fees. It is ideal for alarm systems, control panels and smart IoT equipment where consistent communication is critical.
Justworx SIM cards operate on devices that support cellular roaming and manual APN configuration, allowing them to automatically connect to the strongest available network.
Non-Steering Multi-Network Connectivity
Justworx SIM cards are non-steering, meaning they are not locked to a single mobile network. Instead, they dynamically connect to the strongest available network at any location, improving reliability for security and IoT applications.
In South Africa, Justworx operates on Vodacom and MTN networks.

Installing a SIM card ensures continued monitoring and communication during internet outages.
Compatibility note:
The entry-level Ajax Hub 4G does not support roaming SIM cards.
Justworx SIM cards are supported on:
- Hub 2 series: Hub 2 (4G) and Hub 2 Plus
