eSIM vs physical SIM
When to choose eSIM (eUICC) and when a removable SIM is enough.
| Criterion | Physical SIM | eSIM (eUICC) |
|---|---|---|
| Operator switching | Physical swap required | OTA via RSP (SGP.02 / SGP.32) |
| Multi-IMSI | Limited to stored profile | Multiple profiles on the same chip |
| OEM integration | 2FF/3FF/4FF in socket | Solderable MFF2 or removable |
| International rollout | Per-country manual management | Remote provisioning |
| Device lifecycle | Short to medium | Long (>5 years) |
| Hardware requirements | Standard socket | eUICC-capable module + LPA |
Which standard to pick
Server-initiated RSP push (SM-DP). Proven at scale in large M2M rollouts.
Device-initiated pull flow via LPA. Designed for smartphones and wearables.
IoT-optimized framework: lightweight profiles, server-initiated flow with no UI required on the device.
Global IoT eSIM: one SKU for every market
A global eSIM for IoT devices lets you manufacture a single product and decide the network identity at activation, not at the factory. Devices leave production with a multi-carrier bootstrap profile and download the final profile over the air when they power on in the destination country.
The factory profile connects across 190+ countries and 750+ networks; the destination market's operational profile is downloaded OTA on first power-up.
In countries that restrict permanent roaming (Brazil, Turkey, India, China...), the eUICC downloads a local profile and traffic becomes domestic.
Same hardware for the entire production run and every destination. No per-country variants, no local-SIM logistics at the factory.
If a carrier sunsets a band (2G/3G) or changes terms, the profile is replaced over the air without touching fielded devices.
Check coverage by country and, if your project operates in markets with regulatory restrictions, the analysis of permanent roaming in IoT.
Module compatibility and rollout
1 SIM with 1 GB over 12 months for €15. Measure real coverage and consumption on your device before locking form factor and standard.
Any eUICC-capable cellular module works. For SGP.32, ask the vendor (Quectel, Telit, Fibocom, u-blox...) for the IPA support matrix and minimum firmware version.
SGP.02 for existing M2M fleets; SGP.32 for new designs. Solderable MFF2 for series production or removable 2FF/3FF/4FF.
Profiles managed from the portal and REST API: activation, OTA carrier switching, usage alerts and event webhooks.
IoT eSIM pricing
eSIM data traffic is billed exactly like a physical SIM: pay-as-you-go, no lock-in, real-time consumption dashboard. The eUICC hardware and profile provisioning are quoted per project, based on volume and standard (SGP.02, SGP.22 or SGP.32).
Devices under 10 MB per month. Configurable usage alerts and REST API included.
Data-intensive equipment. Shared data pools available for mixed fleets.
Free shipping to Spain in 24-48 h. To validate the full eUICC/RSP flow, book a technical call and we size your case.
Frequently asked questions
- How much does an IoT eSIM cost?
- Data is pay-as-you-go: from €0.005/MB for low-consumption devices (sensors, smart metering) and from €1.50/GB for data-intensive deployments (video surveillance, POS). No lock-in. eUICC hardware and profiles are quoted per project based on volume; request a quote with your use case.
- Does eSIM pricing differ from physical SIM pricing?
- Not on traffic: the pay-as-you-go structure is identical. The cost difference sits in the eUICC component (solderable MFF2 or removable) and in remote profile provisioning, which depend on the chosen standard (SGP.02, SGP.22 or SGP.32) and fleet volume.
- How do I test the service before deploying?
- With the SIM Test Kit: 1 SIM with 1 GB over 12 months for €15 VAT included and free shipping to Spain. To validate the full eUICC/RSP flow with your modules, book a technical call and we prepare a tailored trial.
- What is the difference between eSIM and eUICC?
- eSIM is the commercial term; eUICC (embedded Universal Integrated Circuit Card) is the underlying GSMA-standardized component. An eSIM contains an eUICC chip that holds multiple operator profiles and manages them via Remote SIM Provisioning.
- When should I pick SGP.32 over SGP.02?
- SGP.32 is the modern IoT framework: lightweight profiles, server-initiated flow with no UI required on the device, no SM-SR. SGP.02 is still valid for already-deployed M2M fleets. For new IoT deployments with compatible modules, SGP.32 cuts provisioning cycles. Details at /resources/comparisons/sgp22-vs-sgp32.
- Can I switch operators without replacing the device?
- Yes. That is the key benefit of eSIM/eUICC. Profile switching is done OTA from the portal or the API. Useful when a device crosses borders or regulatory regions, or when an operator stops offering service.
- How many profiles fit on an eSIM?
- Up to 10 simultaneous profiles depending on the eUICC variant. Only one is active at any time; the rest stay installed and can be activated OTA.
- Does the iot.cards eSIM work with any module?
- It works with any cellular module compliant with the eUICC standard and with LPA (Local Profile Assistant) when required. We validate module-by-module compatibility during onboarding.
- Is there a coverage difference vs the physical SIM?
- Same coverage: 190+ countries, 750+ networks. The difference is operational (profile management, OTA operator switching), not network footprint.
- Does it support multi-IMSI?
- Yes. An eSIM can hold several profiles with different IMSIs and switch between them based on country, coverage or cost. More at /resources/glosario-iot/multi-imsi and /resources/blog/multi-imsi-explicado.
- Does the IoT eSIM work for global deployments?
- Yes. The multi-carrier bootstrap profile connects across 190+ countries and 750+ networks, and in markets with permanent-roaming restrictions the eUICC downloads a local profile over the air. You manufacture a single SKU and decide the network identity at activation, not at the factory.
- What is the difference between an eSIM and an IoT SIM card?
- An IoT SIM card defines the service: M2M data plan, APN, management portal and API. The eSIM (eUICC) is the physical medium and provisioning technology, letting you swap the operator profile over the air. Our IoT eSIM is an IoT SIM in eUICC form; the comparison at /resources/comparisons/esim-vs-traditional-sim covers when each one fits.
- Which cellular modules support SGP.32?
- Modules with IPA-capable firmware, common in modules released from 2024 (Qualcomm, Sequans or Sony Altair chipsets; integrators such as Telit or Fibocom). For SGP.02 and SGP.22 a standard eUICC module is enough. Ask the vendor for the support matrix and minimum firmware version; we validate it with you during onboarding.
