Commercial comparison
iot.cards vs single operator
One SIM with access to 750+ networks in 190+ countries, no lock-in and automatic switching across operators. Versus the traditional model: one SIM per operator, tied to its footprint, its outages and its commercial policy.
Side-by-side feature comparison
Same device, same deployment. The only thing that changes is who your connectivity depends on.
| iot.cards | Single operator | |
|---|---|---|
| Coverage | 750+ networks in 190+ countries | Limited to the operator's footprint and its roaming agreements |
| Network switching | Automatic to the best available operator (multi-IMSI) | Manual or unavailable — if the network drops, the device goes offline |
| Static IP | Public or private, end-to-end static IPv4 | Available only in premium enterprise plans |
| Private APN | Dedicated, with your own CIDR range and IPSec/WireGuard tunnel | Possible but with high fixed cost and long lead times |
| Lock-in | No lock-in. Activate/deactivate SIMs on demand | Typical 12-36 month contracts with volume commitments |
| Technical support | Network engineers, integration + APN + static IP | Standard carrier support; network engineers only for large accounts |
| API integration | Documented REST with webhooks, ICCID idempotency and HMAC | Variable: some offer an API, others only a web portal |
| Permanent roaming | Yes, no disconnection from extended foreign stays | Limited to 90 days in many cases (inherited from consumer SIMs) |
Pricing model
No minimum monthly fee per SIM. Three tariffs depending on aggregate fleet volume:
| iot.cards | Single operator | |
|---|---|---|
| Model | Pooled across the fleet, no per-SIM minimum | Fixed monthly fee per SIM + GB bundle + overage |
| Tariff | €0.005/MB at low usage, volume discounts at high usage | €1-5 per SIM/month fixed depending on plan |
| Overage | Same per-MB price; no penalty | Typical overage 2-10× the bundled price |
| Minimum SIMs | 1 | Often 50-100 SIMs to access real M2M tariffs |
Frequently asked questions
- But my operator gives me premium support with an account manager.
- Understood, and for many companies that is worth it. iot.cards also assigns a technical point of contact from day one — independent of account size. If your current account manager gives you a written SLA, a sealed contract and a tariff that scales reasonably, you may not need to switch. If it gives you predictable invoicing but connectivity tied to a single network, you have a single point of failure.
- Doesn't switching between networks add latency or disconnects?
- Handover between operators happens when the active network loses signal or drops — the moment when, with a single operator, the device would go offline anyway. Multi-IMSI does not introduce latency in normal operation: the modem attaches to one profile at a time. The switch is the difference between being offline and coming back online in under 30 s.
- Isn't multi-IMSI more expensive? I'm paying for networks I don't use.
- No. Pricing is per MB consumed, not per available IMSI. Having access to 4 operators in Spain costs the same as having access to one: only the traffic you actually use is billed.
- What if I want a private APN with one specific operator only?
- Valid case when you already have site-to-site infrastructure against that operator and migrating costs. iot.cards can act as a multi-operator layer on top of your existing APN, or anchor the private APN to a specific network if that is the requirement. We discuss it during onboarding.
- I've been with the same operator for 8 years. Is it worth switching?
- Depends on the cost of your downtime. If a 4-hour outage costs you less than switching, stay where you are. If an outage costs more than the annual cost of going multi-operator, the calculation is different. For many integrators with SLAs to their end customer, the deciding factor is not price — it is removing the single point of failure.
- Do I lose the phone number / IP / APN if I migrate?
- The IMSI changes (by definition — it is a new SIM), so we usually recommend gradual migration: pilot fractions of the fleet first and rotate as devices come up for maintenance. Private APN and static IP are replicated in the new infrastructure. There is migration effort; we size it during onboarding.
- What about 5G and LTE-M support?
- Same technical coverage as with a single operator when that operator supports the technology. The difference is that if operator A doesn't have 5G yet in a zone but operator B does, multi-IMSI gives you access to that network. Per-country detail at /coverage.
