IoT SIM with static IP (4G/5G)
Short answer
An IoT SIM with static IP assigns a stable IP — public or private — to your device, instead of the NAT-ed, rotating IP that standard SIMs hand out. You connect directly to the device (router, NVR, PLC, alarm) from your system without DDNS, without intermediate tunnels, and without the connection changing identity every time the SIM hands over.
The problem static IP solves
Standard SIMs typically hand out private IPs behind the carrier NAT, which change every connection. Fine for pushing telemetry out to a cloud, but not for reaching the device from outside. If you want to SSH into the 4G router, view the on-site NVR, read a PLC, or manage an alarm directly, you need an IP that doesn't change and can be reached.
- Dedicated public IP per SIM
- Alternative: private IP over site-to-site VPN
- No carrier NAT, no DDNS
- Works with any M2M router or device
Public vs private: which to ask for
Public IP: simplest. Any external service reaches the device by its IP. Right when the device is the server (NVR, router with web UI, accessible PLC). Private IP (RFC1918) over site-to-site VPN to your corporate network: more secure, recommended for sensitive traffic. Both are delivered per SIM, not per fleet.
Typical cases
Alarm Receiving Centers that must receive panel signals without opening ports on the customer side, video surveillance where the NVR is reached directly, industrial routers with SSH/HTTPS management UI, EV chargers receiving sessions from the CPO backend, and any case where intermediate-VPN latency is a problem.

Frequently asked questions
How fast is static IP activated?+
Instant from the portal. You assign the static IP to the SIM and the device picks it up on the next connection — no reset, no manual provisioning.
Does it work in roaming?+
Yes. The static IP persists when the SIM switches networks or operates in another country. External access to the device doesn't change.
Do I need a specific router?+
No. Any standard 4G/5G router (Teltonika, Robustel, Cradlepoint, etc.) accepts the network-delivered IP without extra config. For private IPs over VPN, the router must support the agreed tunnel (IPSec, WireGuard, …).
How much does it cost?+
The surcharge is modest and billed per SIM-month. Volume discount on >100 SIM projects. Exact pricing depends on type (public / private) and the geographic range of the IPs.
