Crout by melita.io – Global IoT Connectivity with German Reliability

Scaling IoT projects is never straightforward. Whether you’re integrating connectivity into hardware, managing device fleets or developing platforms for others, success relies on more than just a SIM card. You need flexible infrastructure, clear control tools and experienced support you can trust.

Crout by melita.io delivers all of this. We provide secure, reliable global IoT connectivity, backed by the solid engineering and local support of a German organisation. Because we are part of a licensed mobile network operator, you can scale confidently from prototype to production.

A German Base with Global Reach

Crout was founded in Germany in 2012 to serve businesses and developers building real-world IoT solutions. In 2024, Crout became part of melita.io, the dedicated IoT brand of Melita Limited. Headquartered in Europe, Melita is a fully licensed mobile network operator with more than 30 years of telecoms experience and is a full member of the Groupe Speciale Mobile Association (GSMA).

We continue to support the German market with:

• German-speaking technical support
• Contracts and documentation governed by German law
• A practical and partner-first approach to service

At the same time, we have grown to offer connectivity in more than 190 countries, through over 450 networks and roaming agreements. This provides reliable access wherever your devices need to operate.

SIM Options to Match Your Hardware

From rugged industrial trackers to ultra-compact wearables, we support a full range of SIM formats to suit your device design:

• 2FF (Mini SIM), 3FF (Micro SIM) and 4FF (Nano SIM)
• Embedded SIMs (MFF2)
• QR code-based eSIMs (Profiles) for remote provisioning

Our offer is based on eUICC SIMs for extended reliability and lifetime use. We are able to switch profiles and IMSIs for use cases that require long-term flexibility, switching between operators over time or managing coverage across multiple regions.

A Platform That Puts You in Control

Managing connectivity should not involve complicated processes or ongoing manual tasks. Crout by melita.io provides a powerful SIM management platform that gives you visibility, control and automation tools from day one.

Features include:

• User roles and permission levels that reflect your team structure
• Triggers and automation options to simplify device lifecycle management
• Real-time usage data and clear billing breakdowns
• Full API access so you can integrate everything into your own environment

Whether you manage ten SIMs or ten thousand, the platform is designed to support your growth.

Flexible Commercial Models for Partners and Providers

We work with partners across the IoT ecosystem. These include software developers, systems integrators and device manufacturers. Together, we design commercial models that reflect your needs and create value for your customers.

Available options include:

• Flexible tariffs and billing structures
• Custom data bundles and commercial terms
• White-labelling, so you can offer connectivity as part of your own brand

Because we are independent and agile, we adapt to your model — not the other way around.
