Welink IoT Connect

M2M IoT SIM cards are engineered specifically for machine communication, not consumer smartphones. Built with industrial components, they resist extreme temperatures (-40°C to +105°C), support aggressive deep-sleep power cycles, and feature tailored pricing models starting at €1/month/SIM for low-data telemetry. Unlike consumer SIMs, they never expire from inactivity and are remotely managed OTA (Over-The-Air profile switching and carrier steerage) without physical replacement.

There is no technical ceiling. Our cloud platform effortlessly manages from 10 to over 100,000 SIMs with automated data pooling (unused megabytes from low-usage sensors offset high-bandwidth devices). Rates scale downwards with volume: from €1/SIM/mo for 10 MB telemetry up to multi-gigabyte pools for video surveillance or autonomous robots. Manage everything from one unified console.

Yes. European roaming across 30+ countries is bundled into all standard IoT packages at zero additional roaming surcharge. For worldwide deployments (Americas, Asia, Africa), we provide multi-IMSI SIMs with intelligent carrier steerage: the SIM automatically attaches to the most reliable and cost-effective local network in each country.

We implement a 3-tier defense-in-depth security architecture. Layer 1: Private APN (Access Point Name), isolating device traffic completely from the public internet. Layer 2: Hardware-accelerated IPSec AES-256 encrypted VPN tunnel between edge routers and your corporate cloud/datacenter. Layer 3: Deep packet inspection firewall filtering traffic by IP whitelist, port, and protocol. Zero exposure to internet scanning bots.

Our cellular SIMs and routers natively support standard IoT protocols: MQTT, CoAP, LwM2M, HTTP/HTTPS, and industrial Modbus TCP/IP. Across the radio layer, we support 2G (for legacy low-power systems), 4G LTE-M (Cat-M1) and NB-IoT (for extended battery life and deep indoor penetration), and high-speed 5G for mission-critical video streams and robotics.
