Drillisch Online

What Drillisch Online does

Drillisch Online GmbH is a German mobile virtual network operator (MVNO) headquartered in Frankfurt am Main that delivers mobile telecommunications services — voice, SMS, and data — to price-sensitive German consumers under multiple sub-brands including handyvertrag.de, winSIM, sim.de, and smartmobil.de. The company is a wholly-owned subsidiary of 1&1 AG and operates over the 1&1 Mobilfunk GmbH mobile network infrastructure, including 5G capacity built in partnership with Rakuten as general contractor. Its product portfolio spans tariff subscriptions, hardware sales (smartphones and accessories), eSIM, MultiCard, RCS Business Messaging, VoLTE/VoWiFi, smartwatch connectivity, international roaming packages, cloud storage, and DSL connections with on-site installation, supported by the Servicewelt self-service portal (web and mobile app).

The business model is a consumer-direct, online-first subscription model with monthly recurring revenue from mobile tariffs complemented by one-time hardware sales, bundled third-party services (Norton security, domains/SSL), and loyalty monetization via Payback. Drillisch Online acquires customers through a broad digital marketing stack — paid social (Facebook, TikTok), paid search (Google, Bing), affiliate networks (AWIN), display networks (Communication Ads/Adition), and customer referral — and retains and services them through the Servicewelt platform, phone hotlines, and a partner/vermittler portal. AI features are applied in operational layers: an NLP chatbot for Info-Center knowledge retrieval, voice AI for hotline PIN authentication, and anomaly-detection-based fraud prevention built on credit bureau data (SCHUFA, Infoscore) and identity verification (WebID, DHL Ident-Check).

Operationally, the company is regulated by the Bundesnetzagentur and the Bundesbeauftragte für den Datenschutz, is GDPR-compliant with joint-controller arrangements for advertising data (Facebook, TikTok, 1&1 Telecommunication SE), and has filed a BFSG/BFSGV accessibility compliance declaration dated 26 June 2025. The company does not disclose revenue or headcount figures publicly; recorded headcount band is 101–250 employees. The corporate strategy is best characterized as defending a price-leading position in the German discount mobile segment through multi-brand reach, parent-group infrastructure leverage, and incremental product and channel expansion (eSIM, RCS, WhatsApp, AI-assisted service) rather than aggressive growth-stage scaling.
