    Our Story

    Born from a frustration our customers know all too well.

    Years ago, a pay as you go SIM could be topped up with credit that lasted until it was used. That is no longer how most major networks work. Credit may still be available, but it commonly expires after a month. An intercom uses very little talk time, so customers end up paying for credit they do not use, while also having the hassle of remembering to top up and administer it.

    A contract style mobile plan removes the top up problem, but it is often more service and cost than an intercom needs. Multi network SIMs then flooded the market, but they are not the dependable answer either. We used to supply them, so we know their limits first hand. Our founding team set out to create a simpler, more reliable option, working with the major networks and testing with more than 50 intercom and gate systems from every major manufacturer.

    Today, LynixSIM is trusted by thousands of homeowners and hundreds of professional installers across the UK, the connectivity standard for security critical access systems.

    Proprietary Technology

    The right network, chosen before you order.

    Most suppliers leave the network to guesswork and hope the gate is in a good spot. Lynix Signal Intelligence assesses predicted coverage at your exact location against the intercom you are fitting, and recommends the one network most likely to hold. One network, chosen deliberately, then left alone.

    Assessed Before Dispatch

    Signal Intelligence models predicted coverage at your precise location and weighs it against what your specific intercom actually needs before a SIM is posted to you.

    One Network, Locked On

    Your SIM runs on the single network chosen for your site: Vodafone, O2 or EE. No messy multi network SIM, roaming handovers or bouncing between carriers. Just a stable, predictable connection your system can rely on.

    Fixed, Not Drifting

    The network is set when the SIM is issued and stays there. No overnight re-registration or silent move to a weaker mast. The connection your installer tested on the day is the connection you keep.

    Built for Gates & Intercoms

    Tuned end-to-end for security-critical access systems. The reliability and responsiveness installers demand, and homeowners depend on.
