How one of our Customers benefits from our Modern DATA SIM connectivity.

A long term Holbrook Telecom client has their internet enabled, equipment installed across several hundred Government, NHS and Commercial sites.

Their equipment is used to check the Security, Health and Safety credentials of various trades people attending site to carry work across the sites.

Some of their larger installations can have ten or more entry points, where individuals can be given access to a clients site.

Sometimes it can be difficult negotiating with the IT departments and network security teams of large organisations to get the required connectivity. Not to mention that wired internet access is not always available it the precise location required.

We have helped them solve this problem by providing data only SIMs with the following features

Static IP address

The SIM cards we provided have static public IPv4 address so that they can be easily accessed securely across the internet.

Limited Data, Aggregated Data

We configured the SIMs with just the right amount of data to keep costs low.

    SIM Card Management

    We offer both managed and unmanaged Data SIM solutions


    If your solution is large-scale or multi-site (think IoT sensors), you’ll want to opt for a managed service. You’ll be able to monitor your entire base in real-time, make changes on the fly, set up usage alerts, lock SIMs to devices, the list goes on.


    If your solution is single site and data hungry (think primary connectivity in an office), this is the better, more cost- effective option.

    Dynamic or Static IP addresses.

    Dynamic is the standard for most SIM cards and also the most cost-effective.

  • Static, if a standard dynamic IP won’t cut it, we’ll set you up with a public or private static IP one, crucial if you’re hosting your own server, running hosted applications or need to access devices remotely.

    Networks and Roaming

    Unsteered multi-network

    One SIM, multiple networks. The devices these SIMs power will find the network with the best signal, wherever they go, making unsteered multi-network SIMs easy to deploy and extra resilient.

    They’re best for critical applications, large scale deployments, or solutions that move cross country.

    Single network

    One SIM, one network. Great for single site, non-critical deployments

    Connectivity technology


    Perfect for low data solutions that need to retain as much battery life as possible, NB-IoT has a huge range and draws minimal power.


    Designed for IoT devices, LTE-M has a similar speed and latency to 3G—perfect as an alternative to 3G services before the upcoming 2G/3G sunset.


    4G is the go-to option for data-hungry, low latency applications, like wireless broadband.


    Blazing fast speeds, ultra reliable, and the ability to connect 1 million devices per km2—5G is the most powerful connectivity around, even out performing fixed line performance.

    Data plans


    One flat cost, absolutely unlimited data. Best for data-hungry solutions that’ll chew through data fast.


    A single pool of data that multiple SIMs share. Great if you’ve got multiple sites with varying usage to connect


    A smart tariff that’ll automatically adjust data tiers according to your usage each month—great if your usage will vary significantly and you want to

    avoid overage.

    Per unit

    If you can predict exactly how much data your solution will use, you can opt to pay by the bit.


    Buy a block of data and just top up when a SIM has used its limit. This one is specifically designed for temporary deployments.

    Connection type

    Internet access

    Like typical wired broadband, your device will access the internet via the most resilient providers.

    Custom Access Point Name or APN

    Via a custom APN, we’ll segregate your traffic away from slow public pathways. That means a faster, more secure, completely customisable service —perfect for corporate networks.
