Global IoT SIM cards

Our carrier-agnostic IoT SIMs have access to multiple networks wherever you deploy. As you expand into new countries, you’ll never need to negotiate or integrate with new providers. Using Multi-IMSI technology, our SIMs store up to five subscriber identities and switch profiles as needed. With eUICCs, you can provision SIMs with new profiles Over-the-Air (OTA).

Automatic network selection

Automatic network selection

Whether you optimize for signal strength or data rates, your devices will select the best available network by default. If the preferred cellular network doesn’t have service, your device automatically finds one that does.
Pricing made for IoT

Frequently Asked Questions

What is an IoT SIM card?

IoT – or M2M – SIM cards provide access to cellular networks to connect devices – with a management platform to monitor and operate device connections at scale. If you want two or more ‘Things’ (connected devices) to communicate with each other, then you need a data connection. In most cases, a standard cellular mobile SIM (or consumer SIM) won’t cut it.

How is a consumer SIM different from an IoT M2M SIM?

Consumer SIMs are bound to one local network operator and impose high roaming costs for data connections in foreign countries or outside a common tariff zone. IoT SIMs meanwhile give your devices access to multiple networks per country, a single tariff plan for global use, and flexible, usage-based contract terms. IoT SIMs also have more memory, durability and a longer lifespan than consumer SIMs.

IoT SIMs usually come with a web-based platform for remote SIM and connectivity management. They come in multiple form factors like the industrial-grade or MFF2 for durability against extreme environments – heat, corrosion, vibration.

Check out our detailed article on the differences between a consumer SIM and an IoT M2M SIM.

How much does an IoT SIM card cost?

The price can start from less than EUR 2 for a commercial-grade EMnify IoT SIM and less than EUR 3 for an industrial-grade EMnify IoT SIM depending on your order volume. A discount automatically applies as more SIM cards are purchased within an order.

New users can get three EMnify IoT SIM cards for free when signing up for an evaluation. Try it out for yourself, at no cost, for a 60-day trial. Visit EMnify Pricing Page to learn more.

How do I activate my IoT SIM card?

Activating an IoT SIM card is straightforward and usually only involves a few simple steps. Often there is more than one way to activate a SIM – for example, either through a connectivity management portal, API or sometimes even a no-code solution. IoT SIM cards can be registered and activated individually or in bulk – significantly speeding things up when connecting a large fleet of devices.

What is factory test mode?

You also have an option to enable factory test mode where your devices are pre-activated and allocated with a fixed amount of free data traffic. During factory test mode, there is no SIM

hosting fees and data charges, allowing you to test device connections during QA processes and ship preactivated devices to customers without incurring connectivity costs.

Once your devices use up the free data after being deployed, the EMnify SIM cards automatically switch to “active”, and only then your monthly billing starts. There is no need to activate your SIM cards when using factory test mode.

How can I monitor the performance of my SIM cards?

A connectivity management portal will typically provide access to real-time monitoring of all connected devices, tracking things like connection status, data usage and cost.

The EMnify Portal also provides tools like connectivity reset and network blocklist that let you quickly troubleshoot connection issues and reduce Tier-II support tickets.

If you prefer monitoring device connectivity and data consumption directly from your existing operational dashboards and application, the EMnify Data Streamer lets you do so. Learn more about Data Streamer or view our Integration guides for detailed instructions

What is an eSIM?

eSIM is a SIM type that allows you to change an operator profile Over-the-Air (OTA) with remote SIM provisioning capability. The term eSIM could also be interchangeably used to indicate an MFF2 SIM type that gets soldered directly into a cellular device.

How do I swap carriers/Can I choose whichever carriers I want?

The EMnify SIM card uses multi-IMSI approach and automatically selects the best-quality network at your device location. In cases where you want to select a specific operator for your devices, the network blocklist function allows you to proactively switch to your preferred network.

Does EMnify IoT SIM support Narrowband-IoT and LTE-M?

Yes. EMnify IoT SIM supports multiple cellular technologies including LTE-M and NB-IoT. Visit our LTE-M coverage page and NB-IoT coverage page to find out where your devices can connect via these two technologies using the EMnify SIM.
