Frequently asked questions


What does “eSIM ready” mean?

All devices are equipped with an eUICC. The eSIM/eUICC can be used after a firmware update.

No, the Cellulink devices do not have a VPN function. Especially when the device is mounted remotely in public spaces, unencrypted communication from your application to the mounting location of the device provides a target for attack. Your application should always be end-to-end encrypted. Use a VPN-capable controller such as PLCnext Control or a security appliance such as the mGuard product family for this. The normal Internet communication to a cloud or to web servers should already be encrypted. Use TLS encryption (HTTPS, MQTTS), for example, for this. A VPN function in Cellulink is then no longer necessary. If you still need a cellular router with VPN function, use the TC ROUTER product family.

The devices do not have an energy-saving mode. However, you can switch off the cellular module via web-based management or an API. This significantly reduces the energy consumption of the device. Communication via the cellular network is then no longer possible.
You can achieve maximum energy savings by switching off the device completely. For example, a controller can switch the PoE supply via a relay. Please note that it takes some time for the device to start and be registered in the cellular network.

How is the device supplied with power?

In contrast to the M40 version, you cannot supply the M25 version with DC voltage. The M25 version is supplied with power via the Ethernet cable. You can use PoE according to 802.3af or passive PoE for this.
