What Tango Networks does
Tango Networks, Inc. is a privately held Delaware corporation headquartered in Frisco, Texas with a regional office in Leeds, United Kingdom. Founded in 2004–2005, the company has spent two decades developing Fixed-Mobile Convergence (FMC) technology that brings mobile communications inside enterprise governance frameworks. Its flagship product, Tango Extend, provisions a business-line eSIM onto any smartphone and integrates that line with enterprise UC platforms — including certified native integrations with Microsoft Teams (Operator Connect) and Cisco Webex Calling (Webex Go), plus support for Zoom Phone, RingCentral, 8x8, Dialpad, and Genesys. Calls route over the cellular voice channel through the phone's native dialer (no app required), preserving corporate identity, routing, recording, and policy controls.
The underlying platform combines eSIM provisioning, VoLTE and WiFi Calling, dual identity separation, and a custom global mobile network operating across more than 40 countries. Supporting modules include Enterprise Text Messaging (SMS/MMS), Fixed Wireless Device Plans for deskphones and ATAs, and a usage-based Global Pass Day Pass for international roaming. The company holds multiple patents in FMC, is ISO/IEC 27001:2022 certified, and maintains GDPR/CCPA/HIPAA-aligned compliance posture for regulated industries.
Tango operates a 100% channel-first go-to-market, selling exclusively through approved Communication Service Providers, Managed Service Providers, and Value-Added Resellers. Revenue is generated through monthly subscriptions (Second Line, Limited High Speed Data, and Unlimited High Speed Data plans) plus usage-based Day Pass add-ons. The company serves primarily enterprise and mid-market customers in financial services, healthcare, insurance, retail, recruitment, and consulting, with a particular focus on frontline workers and compliance-driven communications use cases. Co-founders Douglas J. Bartek (CEO) and Andrew Silver (CTO/CISO) continue to lead the company alongside a small executive team.

Tango Networks competitors and assessment
Company assessmentBroad incumbents
- Cisco (Webex): Provider of Cisco Webex Calling, the second dominant UCaaS platform that Tango integrates with via Webex Go. Same dynamic as Microsoft — partnership today but a structural competitive risk if Cisco extends Webex Calling natively to mobile eSIM.
- Sinch: Global CPaaS leader offering mobile messaging, voice, and verification APIs that overlap with Tango's enterprise SMS and mobile voice capabilities. Both serve enterprise customers integrating mobile communications into business workflows, though Sinch is API-first versus Tango's managed FMC service.
- Vonage (Ericsson): UCaaS/CPaaS provider owned by Ericsson offering cloud communications including voice, messaging, and video. Competes with Tango's mobile UC vision at the platform layer, with broader API and contact-center reach but less specialised fixed-mobile convergence depth.
- Microsoft (Teams Phone): Operator of Microsoft Teams, the dominant enterprise UC platform that Tango Extend integrates with via Operator Connect. Microsoft could natively extend Teams to mobile dialers and would be the single largest competitive threat if it built comparable cellular-native features.
Direct peers
- RingCentral: Leading UCaaS platform with native mobile apps and integrations that Tango Extend supports directly. RingCentral is both a partner integration target and a competitive substitute — enterprises could choose RingCentral's first-party mobile experience over Tango's eSIM-based extension.
- Dialpad: AI-powered UCaaS platform with mobile softphone and business communications. Listed as a Tango Extend integration partner and a competing provider of mobile business voice — represents the same dual-partner/competitor dynamic as RingCentral and 8x8.
- 8x8: UCaaS/CCaaS provider with integrated voice, video, and contact center offering mobile apps for business communications. Similar to RingCentral — listed as a Tango integration partner while also being a competitive UCaaS suite that includes mobile capabilities.
- Net2Phone: UCaaS and mobile communications provider offering hosted voice, SIP trunking, and mobile solutions to SMB and enterprise customers. Comparable business model of bundling mobile with UCaaS, similar channel partner GTM focus, and overlapping regulated-industry compliance positioning.
- Zoom Phone: UCaaS offering from Zoom providing business voice with mobile applications. Listed as a Tango integration partner and a competing UCaaS solution that enterprises may choose instead of pairing Zoom with Tango Extend.
- Sangoma Technologies: Provider of UCaaS, PBX, and SIP trunking services including mobile integration through products like Star2Star. Comparable to Tango in serving SMEs and enterprises needing unified communications with mobility features, with broader on-premises and cloud PBX capabilities.
