Ajax SIM 12-Month Roaming Cellular Backup Subscription for Ajax Hubs

Ajax SIM 12-Month Roaming Cellular Backup Subscription

The Ajax SIM 12-Month subscription is a pre-installed roaming SIM service designed to keep an Ajax alarm hub connected to the Ajax Cloud even when Ethernet or Wi-Fi is unavailable. Rather than shipping as a physical accessory to unbox, this is a carrier-agnostic cellular data service that activates directly through the Ajax app and provides twelve months of continuous mobile connectivity for a single Ajax hub, giving installers and end users a reliable backup communication channel for alarm and event transmission.

Key Features

• Pre-installed and pre-activated by the mobile operator, so there is no manual SIM configuration or smartphone activation step required.
• Automatically switches between multiple carrier networks to maintain the strongest available signal at all times.
• Supports 2G, 3G and LTE connectivity, ensuring compatibility even in areas with limited network coverage.
• Provides unlimited cellular connectivity distributed through Ajax's carrier partners for the duration of the subscription.
• Each SIM is uniquely locked to a single hub, preventing unauthorised use if the card is removed or misplaced.
• Acts as a resilient backup channel, allowing the hub to search for and connect to a more stable network if the primary connection drops.
• Collects only minimal identifying data (SIM and hub identifiers), reflecting a privacy-conscious design.
• Removes the need to source, test, or manage a third-party SIM card and data plan for the alarm system.
• Activated and managed entirely through the Ajax app, with no separate carrier account needed.

Reliable Connectivity for Installed Alarm Systems

This subscription is best suited to residential and commercial properties where internet connectivity cannot always be guaranteed, such as sites with unstable Wi-Fi, no fixed-line internet, or locations prone to outages. Installers commonly use Ajax SIM as a redundant communication path alongside Ethernet or Wi-Fi, so that alarm events, arm/disarm signals, and monitoring data continue to reach the Ajax Cloud and any connected alarm receiving centre even during a network fault. It is particularly valuable for remote sites, rental properties, and premises where a dependable secondary link is essential for certified monitoring.

What's in the Box

• This is a subscription service rather than a physical accessory — there is no separate SIM card packaged for self-installation.
• The roaming SIM is factory pre-installed inside a compatible Ajax hub.
• Activation and management occur through the Ajax app or Ajax PRO Desktop for a 12-month service term.

Frequently Asked Questions

Does this subscription include a physical SIM card I need to insert myself?
No. The SIM is already installed inside compatible Ajax hubs at the factory; this listing covers the 12-month service subscription only.

What happens if my primary internet connection fails?
The hub automatically falls back to the roaming cellular network, helping maintain uninterrupted alarm and event transmission.

Can I use this SIM in more than one hub?
Each Ajax SIM is linked to a specific hub for security reasons, though it can be transferred to a different Ajax hub if required.
