M2M SIM Spain — no lock-in (Telefónica, Vodafone, Orange, MásMóvil)

M2M SIM with multi-network access in Spain — Telefónica, Vodafone, Orange and MásMóvil — and 190+ countries. Instant activation, Spanish monthly invoicing, no annual commitment. 2G, 4G LTE, LTE-M and NB-IoT profiles, no minimum monthly fee per SIM, no permanent-roaming restriction. For integrators, installers and companies who need industrial M2M cards without being tied to a single carrier and without termination penalties.

Carriers and M2M technologies in Spain

Spain is our home market since 2013. The SIM connects to the three national mobile networks with priority and fallback configurable per location, using M2M-specific profiles (not recycled consumer ones).

3G is being switched off progressively (Vodafone Spain completed sunset in 2024; Orange and Movistar are following their own calendars). For new deployments plan directly on 4G LTE / LTE-M / NB-IoT. LTE-M and NB-IoT availability depends on the carrier and area; request a SIM Test Kit to field-test technology by location before a bulk order.

Typical M2M use cases in Spain

• Electricity and water smart metering (meters, PLC concentrators)
• Industrial telemetry and SCADA (substations, tanks, pumping stations)
• Connected vending machines and micro-markets
• Agricultural machinery and precision farming (LTE-M / NB-IoT)
• EV charging stations (OCPP, eMSP roaming)
• Industrial routers and SD-WAN for retail and remote offices
• Residential and industrial alarms (IP or SMS events)
• Connected elevators (2G → LTE-M migration for EN 81-28)
• Remote medical equipment and telemonitoring
• Fuel telemetry, BESS and photovoltaic plants

Frequently asked questions about M2M SIMs in Spain

Can the M2M SIM use any Spanish carrier, or just one?

Any of the four: Telefónica, Vodafone, Orange or MásMóvil. The SIM is not locked to a single carrier, so if your area has stronger coverage on one operator over another, the device automatically attaches to whichever has the best signal. No contract changes if a carrier later loses coverage in some deployment.

What's the difference between an M2M SIM and a consumer SIM?

M2M SIMs are designed for unattended devices: they don't expire on inactivity, don't get cut off after 90 days roaming, support flat per-MB tariffs with bundles pooled across devices, and allow REST-API lifecycle management. Consumer SIMs assume a human user (periodic verification, manual top-ups, permanent-roaming restrictions). Recycling consumer SIMs into industrial IoT deployments creates silent disconnects at the 90-day mark that you only notice when the device stops reporting.

What does "no permanent-roaming restriction" actually mean?

European consumer SIMs are subject, by BEREC regulation, to a fair-use mechanism that disconnects or passes through the visited-carrier cost after a few weeks of continuous use outside the issuing country. iot.cards M2M SIMs are issued with M2M-only profiles that aren't subject to that restriction: a device can spend 12 months outside Spain without the SIM expiring or being throttled. Useful for international fleets, long-term rental equipment and exported devices.

Which physical form factors are available?

2FF (Mini SIM, 25×15 mm), 3FF (Micro SIM, 15×12 mm), 4FF (Nano SIM, 12.3×8.8 mm) and solderable MFF2 WLCSP (5×6 mm, soldered directly on PCB). All four carry the same logical IMSI and the same assigned plan, which means you can move one identity from a 4FF prototype to MFF2 OEM production without re-provisioning. Industrial range -40 °C to +105 °C on MFF2.

Does it support NB-IoT and LTE-M in Spain?

Yes where the local carrier has them deployed. NB-IoT has improved a lot with Movistar and Vodafone in recent years, especially for smart metering. LTE-M is more widespread in cities and logistics corridors. To validate availability at a specific location before a bulk order, the fastest path is the SIM Test Kit (free shipping to Spain) and a field test: the modem reports which technology it negotiates and the link quality.

Is there lock-in or a minimum fee?

No. Each SIM is billed per usage or per its contracted tariff, with no lock-in and no monthly minimum. A provisioned SIM with no traffic generates no charge. Pause and reactivation are done from the portal or via API.

How do I bulk-provision SIMs via API?

The POST /sims endpoint accepts batches via CSV or JSON: per SIM, pass ICCID, plan, tags (vehicle plate, location, site) and optionally private APN or static IP. The API is idempotent on ICCID, returns a job_id for progress polling and emits HMAC-signed webhooks on completion. Full documentation at /plataforma/api.

Does it work outside Spain?

Yes. The M2M SIM roams on 750+ networks across 190+ countries, with no 90-day restriction. For European deployments the per-MB cost when roaming in EU/UK is similar to domestic; outside the EU tariffs are published by zone.

What's included in technical support?

Technical onboarding (coverage validation, APN setup, API integration) is free from the first SIM. Operational support thereafter is via email and phone in business-hours CET. For fleets with SLA or enterprise tariffs, 24/7 support with contractual response times.

How do I migrate from my current M2M provider without breaking operations?

Gradual migration: pilot 5-10 % of the fleet, validate KPIs (latency, availability, billing) and rotate as devices come up for maintenance. If your current private APN has specific addressing, we replicate it on the new infrastructure so the SCADA / TMS / VMS integration doesn't notice the change. Migration plan is sized during onboarding.
