SIM, eSIM and IP addressing
How the SIM in your router decides which network it uses, how it gets an IP address and how you reach the equipment behind it. Covers eSIM, multi-network SIMs, fixed IP and private APNs.

The SIM is the part people think about last and the part that causes the most support calls. The right SIM decides whether a router can use more than one network, whether you can reach it from the internet, and how much a fleet of devices costs to run.
Standard SIMs give the router a dynamic, private IP address behind the network's address translation, which is fine for devices that only connect out. Fixed IP SIMs give a static address so you can reach cameras and controllers directly. Private APNs keep traffic off the public internet altogether. eSIM moves the SIM profile into the device itself, so the network can be changed remotely.
We supply all of these, alongside the routers, so we can match the SIM to the job. See our SIM cards range, the multi-network data SIM on a 30-day rolling plan and our fixed IP SIM cards.
Topics in this hub
- eSIM: Embedded SIMs that can be provisioned remotely, so a device can change network profile without anyone swapping a card on site.
- Fixed IP and private APN: Static public or private IP addressing so you can reach devices directly and securely, for CCTV viewing, SCADA and remote access.

Questions
Do I need a fixed IP SIM?
Only if something needs to connect in to the router or the devices behind it, such as an NVR viewing app or a SCADA system. Devices that connect out to a cloud platform, or are managed through Teltonika RMS or a VPN, work with ordinary SIMs.
What is a multi-network SIM?
A SIM that can use more than one UK network and switch to another if the first is unavailable at the site. It is the usual choice for unattended equipment.
