What Digital SIM does
Digital SIM GmbH is a German IoT and M2M cellular connectivity provider headquartered in Preußisch Oldendorf, founded circa 2004 and operating in the DACH market. The company's core offering is a multi-network SIM card that aggregates access to over 500 global mobile networks on a single SIM, with automatic best-signal selection across Telekom, Vodafone, and O2 in Germany and Melita's roaming footprint internationally. It sells tiered subscription tariffs (Pure from €5.90/month, Connect 10MB-10GB, Advanced from €0.40/SIM/month, World Connect for global use without roaming surcharges, Narrowband for LTE-M/NB-IoT, and Festnetz Backup for triple-redundant fixed-line failover), supplemented by a cloud-based management portal that supports data pooling across SIM fleets, custom private APNs, and eSIM provisioning.
The underlying platform integrates with Teltonika's RMS and RutOS for remote device management, supports the full cellular IoT protocol spectrum (5G, LTE-Advanced, LTE-M, NB-IoT, 5G RedCap), and offers physical SIM, eSIM, and MFF2 form factors. GTM is hybrid: direct sales through digital-sim.de and a toll-free 0800 number sit alongside indirect distribution via four DACH wholesalers (Brodos, MichaelTelecom, Herweck, pei tel) and a global technology alliance with Teltonika Networks spanning 150+ countries. Customer evidence spans enterprise gaming (Gauselmann AG), a social-services charity (Menschenskind!), and a cluster of surveillance OEMs (Reolink, Hikvision, Axis, Bosch, Dahua).
In January/February 2026, Digital SIM was acquired by Melita Limited (the Malta-based operator backed by Goldman Sachs Alternatives Infrastructure), bringing Digital SIM under the melita.io brand and extending its reach into 185+ countries. The company is led by Managing Director Iris Smith and co-founder Roland Becker (Director Business Development, retained as shareholder), with reported headcount of 1-10 employees. No funding rounds, patents, awards, or AI/ML capabilities are disclosed in the source data.
