Global M2M SIM cards

With EMnify’s IoT SIMs, you’ll never need to swap SIM cards or worry about negotiating or integrating with new providers. A single SIM stores up to five subscriber identities, so it can attach to the best network wherever you deploy and switch between carrier profiles as needed. You can also provision SIMs with new identities Over-the-Air (OTA).

Simplified connectivity management

With EMnify's connectivity management platform, you can explore analytics for each IoT device or look at entire deployments. You’ll see data usage, status updates, and costs from one convenient dashboard. From the same place, you can also adjust, activate, and pause SIM plans as needed. Using our Restful API, you can automate SIM provisioning and management.

Cloud-based infrastructure

We globally distribute our mobile network infrastructure through public clouds. As you develop your cloud native solution, we can provide simple, automated intra-cloud integrations using standard web services.

Advanced IoT security

Between our connectivity management platform and our specialized IoT SIM cards, your devices and applications benefit from crucial IoT security features like network-based firewalls, SMS firewalls, IMEI locks, VPNs, and more.

24/7 support

We ensure your devices have 99.9% uptime. And while we give you straightforward tools and reliable ways to automate your connectivity, we’re also available anytime you need support. You can reach us 24/7 by phone, email, or live chat, and we can serve you in English, German, Spanish, Italian, French and Portuguese.
