Link Secure SIM

Link Secure SIM cards are connected to a Link Network (IP VPN, see below) in the AddSecure Link service. The mobile subscription works on 2G, 3G, 4G, and NB-IoT networks with almost all operators in the Europe and with the major carriers outside of Europe, for global coverage.

Secure SIM uses AddSecure Link’s access point name (APN), which separates traffic from the rest of the mobile data traffic. It directs all traffic to AddSecure’s gateway, which automatically assigns fixed IP addresses and ensures that all data automatically winds up in the correct Link Network. The traffic in the mobile network is always secure as it is encrypted—normally AES256 encryption on the 4G network.

Private networks

One of the challenges of creating an IoT solution is security. Adding layers of security as an afterthought can prove difficult. AddSecure Link makes it easy from start to create a complete private network (VPN) in minutes, encompassing all devices and systems that are supposed to communicate. The network is completely isolated from other internet traffic and closed for unauthorized users and devices. Multiple private networks can be created and managed to cater for separation of a partner’s different end customers, or separation of different types of traffic and systems.

The Link Manager web portal

In the web portal, Link Manager, all the tools necessary to establish and manage your network and connections are available. The user interface is intuitive, with clear guidance, and utilizes a high level of automation, limiting the risk of human errors and thereby increasing security in the deployed solutions.

  • Easy to manage – a complete overview of connections, SIM-cards and traffic plans. Order new SIM-cards, start, change and cancel subscriptions with a few mouse clicks.
  • Easy to manage – one tool for SIM-cards, data traffic management, and network management, a more complete view than standard SIM management tools.
  • Full control – the overview in Link Manager provides possibilities to follow up on cost and data volumes. Setting a fixed data limit per device is easy, ensuring full cost control and no surprises.
  • Scalable – Possibility to set up networks and connections, order new SIM-cards and VPN-certificates, available at your fingertips.

Smart cities and municipalities – where to begin?

A smart city is a city enhanced by sensors, data collection, artificial intelligence and inter-connectivity to manage almost every single part of it more efficiently. Essentially, it’s when the whole city itself goes online – not just the people in it.
