LynixSIM – Consumer Terms and Conditions (30‑Day Rolling SIM Plans)

    Last updated: 29 June 2026

    By ordering and using a LynixSIM SIM card you agree to these Terms and Conditions.

    1. Who we are & how to contact us

    1.1. LynixSIM is a trading name of Lynix Group Ltd, registered in England and Wales (company no. 16624304), with registered office at Westcourt Stables, Westcourt, Burbage, Marlborough, England, SN8 3BW ("we", "us", "our").

    1.2. You can contact us during our support hours:
    Support hours: Monday–Friday, 9:00am–5:00pm (UK time), excluding UK bank holidays
    Email: support@lynixsim.co.uk

    2. What you're buying

    2.1. We provide SIM cards and mobile connectivity for use in gate and entry/intercom systems located in the UK. We do not supply or warrant the intercom hardware itself.

    2.2. We currently offer two 30‑day rolling plans (the "Plans"):

    • 2‑Way Intercom Plan – for intercoms where the caller and the person at the gate can speak to each other.
    • Dial‑to‑Open Plan – for systems where calling the gate number simply triggers the gate or door to open (no two‑way conversation).

    2.3. Prices for each Plan and for the SIM itself are shown on our website at the time you order.

    2.4. When we accept your order and activate the SIM, a 30‑day rolling contract starts for that SIM and Plan.

    3. Length of contract, billing & cancellation

    3.1. Each SIM is on a 30‑day rolling basis, billed monthly in advance.

    3.2. Payment is taken automatically via Stripe using the payment method you provide (for example direct debit or payment card). Your billing period is 30 days from activation (or as otherwise shown at checkout).

    3.3. You may cancel a SIM at any time by telling us (via the website, email or phone). Cancellation takes effect 30 days after we receive your notice. You remain responsible for charges up to the end of that 30‑day period.

    3.4. Once your final 30‑day period has ended, the SIM may be disconnected and the number reused. A new order may be required if you later wish to reactivate service.

    3.5. The upfront SIM price shown on our website is payable when you order and is non‑refundable once the SIM has been dispatched.

    3.6. We do not offer any separate cooling‑off period for these services beyond what is required by law. By ordering, you agree that service may start immediately and that if you cancel, you must still pay for service already provided.

    4. Networks & coverage

    4.1. When ordering you can choose either:

    • a SIM on one of the major UK networks we offer; or
    • an auto‑switch multi‑network SIM, which can connect to more than one UK network and attempts to use the best available compatible signal.

    4.2. There is currently no price difference between fixed‑network and auto‑switch SIMs, but we may introduce different pricing in future for new orders.

    4.3. If you want to change from fixed‑network to auto‑switch (or the other way round), this will usually need a replacement SIM and reconfiguration. Contact us and we will explain what's involved and any one‑off fee.

    4.4. Mobile coverage depends on the underlying networks and local conditions. We cannot guarantee signal at any specific location. Your installer should confirm adequate signal at the gate/intercom before final installation.

    4.5. Our SIMs are for UK use only and must not be used for roaming outside the UK.

    5. What's included in each Plan (high level)

    5.1. 2‑Way Intercom Plan – includes, for use with your intercom:

    • UK voice calling to/from your programmed contact numbers;
    • data required for diagnostics and remote management of the intercom;
    • a bundle of SMS for initial setup (see clause 8).

    5.2. Dial‑to‑Open Plan – includes, for use with your intercom:

    • UK calls from your approved phone numbers to the gate number in order to trigger opening;
    • any data needed for diagnostics and remote management;
    • a bundle of SMS for initial setup (see clause 8).

    This Plan is not intended to support two‑way conversations.

    5.3. Full details of current prices and allowances are shown on our website and may change for new orders from time to time.

    6. If you don't pay

    6.1. If a payment fails, we may contact you and attempt to take payment again.

    6.2. If payment remains outstanding for a reasonable period, we may suspend the affected SIM(s) until all overdue amounts are paid.

    6.3. If amounts remain unpaid after suspension, we may terminate the affected SIM(s) and end the contract for those SIMs by giving you notice. You will still owe all charges incurred up to the date of termination.

    6.4. We are not responsible for any loss you suffer because your gate or intercom cannot be accessed or controlled during any suspension or following termination for non‑payment.

    7. Our rights to suspend or end the service

    7.1. We may suspend or restrict a SIM or service immediately (in whole or in part) if we reasonably believe that:

    • the SIM or service is being used in a way that breaks these Terms;
    • the SIM is being used in a fraudulent, illegal or abusive way;
    • there is a serious security or technical issue; or
    • it is necessary to protect our network or other users.

    7.2. Where reasonable, we will limit suspension to the affected SIM(s) and will restore service as soon as the issue is resolved.

    7.3. We may terminate a SIM and Plan by giving you at least 30 days' notice if:

    • we permanently stop offering the relevant Plan; or
    • there is a serious or repeated breach of these Terms which is not put right.

    7.4. If we terminate under clause 7.3, you will only be liable for charges up to the date the termination takes effect.

    8. How the SIM may be used (restrictions)

    Device‑only use

    8.1. LynixSIM SIMs are device‑only SIMs for use in gate and entry/intercom equipment. They must not be used in phones, tablets, routers, dongles or other devices.

    8.2. The SIM should only be used in the device for which it was ordered and installed. If you wish to move it to another device, please contact us.

    Single‑residence use

    8.2A. Each SIM is licensed for use at a private residence (for example, a private house or a horse estate) only.

    8.2B. Not for residential complexes or large commercial sites. For example, a factory car park is not permitted, but a private horse estate is fine. SIMs must not be deployed across blocks of flats, housing estates, mixed‑use developments, large commercial premises, holiday parks or any multi‑occupancy site without a separate written commercial agreement with Lynix Group Ltd.

    8.2C. Where we reasonably believe a SIM is being used in breach of this clause, we may suspend or terminate the SIM under clause 7 and require migration to a commercial plan. For multi‑residence, residential complex or large commercial sites, please contact support@lynixsim.co.uk to arrange a commercial agreement.

    Calling

    8.3. Calls using the SIM are limited as follows:

    • Calls may only be made to, or received from, UK landline or UK mobile numbers (standard geographic or mobile numbers).
    • Calls to or from premium‑rate numbers, non‑geographic chargeable numbers, international numbers or short‑code services are not permitted and may be barred.
    • The service is not a replacement for a normal phone. You should not rely on it for making emergency calls (e.g. 999 or 112).

    8.4. For the 2‑Way Intercom Plan, each individual call may be limited to a maximum of three (3) minutes. Calls may be automatically disconnected at or around the three‑minute mark to prevent lines being left open.

    8.5. For the Dial‑to‑Open Plan, calls are intended only to trigger gate/door opening from your approved contact numbers. They are not intended for general voice conversations.

    SMS

    8.6. Each SIM includes an allowance of 20 SMS messages to be used for installation, programming and testing of the intercom.

    8.7. After the first 20 messages, outgoing SMS are charged at 12p per SMS (including VAT) at our then‑current rate.

    8.8. SMS may only be used for installation, configuration and maintenance of the intercom system. Marketing, bulk or mass‑messaging and spam are not allowed. We may suspend or terminate the SIM if we reasonably believe it is being used in that way.

    9. Data use and fair use

    9.1. Any "unlimited" data included with your Plan is provided for diagnostics, status, remote management and configuration traffic needed to operate the intercom.

    9.2. The SIM must not be used for general internet access (such as browsing, streaming, downloads or hotspot/tethering) or for other high‑volume data uses.

    9.3. Each SIM is intended for one gate or intercom serving one single private residence or self-contained dwelling only. If your installation serves a block of flats, housing estate, mixed-use development, commercial premises, holiday park or any multi-occupancy / multi-dwelling site, you must contact LynixSIM before ordering so we can agree an appropriate commercial or multi-dwelling plan.

    9.4. If we reasonably believe a SIM is being used outside this fair use policy, we may:

    • restrict or block data on the SIM;
    • charge you at our standard out‑of‑bundle data rates; and/or
    • suspend or terminate the SIM under clause 7.
    10. Our responsibility to you

    10.1. We will provide the service with reasonable skill and care. However, we cannot promise that the service will always be available or fault‑free.

    10.2. In particular, we are not responsible for:

    • the performance or failure of your gate, intercom or other hardware;
    • lack of mobile coverage or weak signal at your location;
    • interruptions or faults caused by the underlying mobile networks or their maintenance activities;
    • any loss you suffer during any suspension or following termination carried out in line with these Terms.

    10.3. Nothing in these Terms limits or excludes our liability for death or personal injury caused by our negligence, fraud or fraudulent misrepresentation, or any other liability that cannot be limited under UK law.

    10.4. Subject to clause 10.3, our total liability to you for any claim relating to a SIM and Plan is limited to the greater of:

    • the total amount you have paid us for that SIM in the 12 months before the event giving rise to the claim; and
    • £200.

    10.5. We are not liable for:

    • loss of profit, revenue, business, contracts or goodwill;
    • loss or corruption of data; or
    • any indirect or consequential loss or damage.
    11. Data protection and privacy

    11.1. We will use your personal data in accordance with UK data protection law and our Privacy Policy, which forms part of these Terms and is available on our website.

    11.2. We will use your information mainly to provide and bill for the service, manage our relationship with you, support your account and meet our legal obligations.

    12. Other important terms

    12.1. We may change these Terms from time to time. If a change is materially disadvantageous to you, we will give you at least 30 days' notice and you can cancel during that period.

    12.2. If any part of these Terms is found to be invalid or unenforceable, the rest will continue to apply.

    12.3. You may not transfer your contract or any SIM service to another person without our consent. We may transfer our rights and obligations to another organisation, but this will not reduce your rights under these Terms.

    12.4. These Terms are governed by the laws of England and Wales, and any disputes will be dealt with by the courts of England and Wales.
