What KeepCalling does

KeepCalling is a privately held international telecommunications platform founded in 2003 and operated by Miron Enterprises, LLC (Atlanta, GA) for non-EU customers and by SC Net Conect, SRL (Sibiu, Romania) for EU customers. Its core function is enabling low-cost international voice calling for individual consumers, primarily within diaspora and expatriate communities who need affordable connections to friends and family abroad. The platform supports calling to 200+ destinations, complemented by local access numbers in 35+ countries for non-internet callers and free iOS/Android apps for VoIP over Wi-Fi or 4G/5G.

The company sells access to its service through five primary product lines: Voice Credit (prepaid pay-per-minute credit), Monthly Plans (fixed minutes subscriptions from $4.99/month), the World Unlimited Plan ($10/month for unlimited calling to 50+ countries), Virtual Numbers ($9.99/month for inbound local-rate calling in another country), Mobile Recharge (one-time prepaid top-ups to 150+ countries), and Travel eSIM (data plans in 190+ countries starting at $2). The technology stack is conventional VoIP with cloud-based call routing, mobile applications, and eSIM profile distribution. Underlying infrastructure includes local access numbers, toll-free US access, PINless dialing, speed dial, voice prompts, and auto-recharge features that enhance the customer self-serve experience.

The business model combines usage-based prepaid revenue (Voice Credit minutes), recurring subscription revenue (Monthly and World Unlimited Plans, Virtual Numbers), one-time eSIM data package purchases, and per-transaction mobile-recharge fees. Go-to-market is product-led growth: customers self-register, pay via card or PayPal, and start calling without sales involvement. Marketing is primarily organic/SEO through the keepcalling.com website, the mobile apps, the Trustpilot reputation (4.1/5 across 11,255 reviews), a content blog, and referral partnerships with Tello Mobile (US wireless) and MobileSIM.com (travel SIMs). The company shows no disclosed funding events, no acquisitions, and no leadership information in available sources.
