What 42com Telecommunication does

42com Telecommunication GmbH is a Berlin-headquartered wholesale voice termination carrier founded in 2005, operating across EMEA, CIS and the Americas through three legal entities (Germany, United Kingdom, Italy). The company provides fraud-free, high-quality international voice termination to Tier-1 operators, mobile network operators, and over-the-top service providers, processing approximately 1.2 billion international minutes per year across 150+ direct routes to a customer base of more than 300 carriers.

The company's core technical infrastructure centers on direct interconnections with in-country operators, active 24/7 quality monitoring using MOS score and CLI verification, and a three-tier routing offering (Direct, Premium, Standard) differentiated by quality and price. Beyond voice termination, 42com operates a Managed Wholesale Voice business that provides back-office outsourcing and profit-sharing models for smaller carriers, an International DID portfolio covering 150+ countries, the Aviso Messaging sub-brand for international messaging termination, and 42com SAT in Italy for LEO satellite broadband and 24/7 Network Operations Center services. Technology differentiators include fraud prevention routing, integration with VSAT, LEO satellite, 5G and IoT platforms, and real-time NOC monitoring capabilities.

42com generates revenue through usage-based per-minute fees for voice termination, transaction-based take-rate models for managed wholesale services, recurring monthly fees for DID provisioning and satellite broadband, and transaction fees for messaging. The company employs approximately 35 people across three offices and sells primarily through enterprise field sales and direct carrier relationships, anchored by named Tier-1 partners including China Mobile International, Lebara Mobile, and Global Carrier. The company is privately held, founder-led by CEO Alberto Grunstein, and has not disclosed any external institutional funding.
