iot.cards
Multi-network IoT SIM cards with EU data residency. 750 networks in 190 countries.
One platform. One invoice. Multi-carrier coverage across Telefónica, Vodafone, Orange and MásMóvil in Spain plus 750+ networks worldwide. No lock-in. Pay only for what you use.
What we solve
Your IoT device needs connectivity that doesn't drop when it crosses a border, doesn't bleed you dry on roaming, and doesn't require a call to a carrier every time you want to change something. iot.cards is exactly that: one SIM, one portal, one invoice.
Our products
Global IoT SIM
A single SIM card that works in 190 countries with automatic network switching. Available in 2FF, 3FF, 4FF and embedded MFF2 formats.
eSIM / eUICC
Over-the-air (OTA) profile management via Remote SIM Provisioning. Change operators without touching the device.
Private APN & Static IP
Your devices on your own private network, with private static IP addressing and VPN (IPSec, WireGuard, L2TP).
Management Portal + API
Activate, deactivate, top up, query CDRs, set usage alerts, GSM geolocate, send SMS and automate everything via REST API.
Our own platform
The software is ours. It has been for over a decade.
The platform behind every SIM was built by us, in Seville. It has been running for over ten years — for us, and for operators you may have heard of.

Frequently asked questions
- What is iot.cards?
- iot.cards is the brand of Kore Logic SL (previously EasyM2M / Lantia IoT, operating since 2013) for cellular IoT and M2M connectivity. We provide multi-carrier SIMs, eSIM, static IP and private APN with coverage in 190+ countries across 750+ networks, managed via portal and REST API.
- How is it different from contracting connectivity with a single operator?
- An iot.cards SIM switches automatically between all available operators in each country. When one network fails or is congested, the device connects to the next without reprovisioning. With a single operator you are tied to its footprint, its outages and its commercial policy.
- How many countries and networks have coverage?
- Commercial coverage in 190+ countries and access to 750+ mobile networks. The exact number shifts month to month depending on roaming agreements; see /coverage for the live list and /coverage/[country] for per-market detail.
- How long does deployment take from the first order?
- For pilots and trials we ship the SIM Test Kit in 24–72 h within the EU from /shop. For deployments with private APN, static IP or volumes above 100 SIMs, operational onboarding usually closes in 1–2 weeks.
- How is usage billed?
- Pooled across the SIM fleet, no lock-in. Three tiers depending on volume: pay-as-you-go (€0.005/MB), data packages (volume discounts) and enterprise (custom quote). Details at /pricing/pay-as-you-go.
- Is there a REST API to integrate the SIM lifecycle?
- Yes. The REST API covers activation, suspension, pause, plan change, usage queries, events and webhooks. Documentation, ICCID idempotency and HMAC verification are explained at /resources/guides/rest-api-integration.
- Who is behind the project and what SLA do you offer?
- Kore Logic SL (CIF B90463662, Sevilla), 13 years in M2M with carrier stack from Telefónica Kite, Wireless Logic Conexa/SIMPro and melita.io. Engineer-led support. Service SLA is agreed by contract depending on the use case (consumer, mission-critical M2M or industrial).
