Take Control of your IoT Network

IoT devices can offer a range of valuable public and commercial services but require secure and resilient IoT connectivity to operate beneficially and profitably.

Managing an IoT SIM card estate and large fleet of IoT devices can become a difficult to manage and costly element of your operations. Our IoT SIM card management platform, monitoring and support services, however make managing your IoT SIMs and therefore your IoT devices a simple and seamless process.

As our IoT SIMs are managed by our platforms, we can provide you with all the support you need to administer your estate. You can activate, suspend or deactivate your IoT SIMs as your business needs change. Our technical support team are also always on hand to implement IoT SIM tasks that you request of you feel too busy or are unsure.

Why Use Multi Network and/or Multi-IMSI IoT SIM Cards?

Multi-network and multi-IMSI SIM cards provide substantial benefits for IoT and M2M service providers, when they are professionally managed. Reasons for using multi-network IoT SIM cards and eUICC IoT connectivity include:

To enlarge geographical coverage and IoT device (signal and coverage) range and reach
Increase and maximise IoT service up-time for distributed IoT device
Ensure resilient and cost-effective cross-border roaming for IoT SIMs and IoT devices
Avoid local, regional, national or international service outages on a single network
Enable medium and high scale IoT connectivity provision and IoT SIM card deployments via remote and centralised management control
Provide a secure and managed network connection to devices and the internet via IoT APN and/or VPN
Provide a true global deployment solution for IoT SIMs and IoT devices
Ensure core roaming network resilience with multi-path and discrete core IoT network systems
Provide post deployment mobile provider flexibility for IoT devices

Connect any IoT Device with Confidence

IoT SIM Cards

Providing the highest quality global coverage IoT / M2M SIM Cards across all sectors. We are relied upon by clients worldwide to supply secure IoT SIM cards and eSIM cards for geo-critical, business critical, and mission critical projects. Our range includes various IoT SIM models and form factors, all of which allow for automatic network selection as they are non-steered. Important, as steered IoT SIMs can lock onto and stay on networks that have poor functionality. Our IoT SIMs of all varieties are managed using our IoT SIM Management System via a ‘single pane of glass’. We have so far supplied over 3 million live connections for customers globally and are trusted as a valued long-term partner by our clients. We also provide fully managed IoT Routers which are designed for industrial, security, retail, hospitality, transport, and telecare applications.

Global IoT Connectivity

We provide secure and resilient global and regional multinetwork IoT SIM cards and single SIM SKU solutions. Tailored for international, multi-country deployments or IoT device roaming with maximum cellular IoT coverage. We also provide a range of specific-functionality, single-network carrier SIM card options (i.e. 02, Vodafone, 3, & EE IoT data SIM(s) in the UK and Verizon in the USA. These tend to be used for specific applications or regions. For example, very high or unlimited data plans, where access to specialised narrowband services is required, or permanent roaming is a concern. IoT cases, where single network or localised eUICC MNO profiles can sometimes be more cost-effective. We also provide single SIM IoT Remote SIM Provisioning (RSP) services (with multiple IMSI profiles available for the maximum geographical coverage and the most flexible cost plans). Ideal for global manufacturers or distributors needing an advanced eSIM solution.

IoT SIM Management Platform & Portals

Our IoT SIM provisioning platform and portals oversee mobile operator IoT connectivity in real-time on multiple networks. The IoT SIM Card Management Platform lets users establish data restrictions for groups, tariffs, or individual SIM cards. Advanced analytics, detailed traffic records, actual costs and forecasts are provided for device groups. The SIM card connectivity management platform includes user-friendly portals for viewing data usage and predicted bills. Configurable warnings notify of problematic devices and unexpected SIM usage, allowing large populations to be managed by exception. We also provide the ability to manage eUICC profiles.

Global & Localised IoT eSIM / eUICC Solutions

Caburn Telecom deploy and deliver leading-edge eUICC IoT SIM cards and IoT eSIM card solutions. We provide advanced eUICC solutions which help solve client problems within specific global use cases and IoT sectors. This includes single and multi-IMSI IoT SIM card solutions which offer a true global footprint. Achieved with either a specific IoT SIM card from one provider, or eUICC IoT SIM cards that allow profiles to change based via Remote SIM Provisioning (RSP). For example, our eUICC SIM cards can be supplied with a global multi-network roaming bootstrap profile for future implementation of eUICC RSP if needed. Or, alternatively, a full eUICC solution with in-built multiple roaming profiles at initial provisioning from day one, with RSP management thereafter. We also provide localised IMSI solutions for those regions where permanent roaming is barred. Our solutions include the ability to deploy manged multi-network profiles via QR codes for the latest Android and iOS devices.

Resilient Multi Network, LPWAN & VoLTE

Our Multi-Network IoT SIM Cards let your devices select and use the best available network at all times. This maximises the areas in which your devices can connect. We work with key IoT roaming providers to offer maximum choice to our clients. We provide truly global solutions with geo-redundancy built in. We can also provide local points of presence to ensure data security where applicable. We provide private IoT APN for routing traffic and VPN solutions where data encryption beyond normal GSM encryption is required. Our VPN solutions also enable secure management of IoT devices via fixed IP. We also provide low power, enhanced range and a selection of our SIMs support narrowband IoT connectivity (NB-IoT, LTE-M, CAT-M1). We also provide cutting-edge IoT VoLTE services.
