What SigueLlamando does

SigueLlamando is an international calling and mobile connectivity platform operated by Miron Enterprises, LLC (doing business as KeepCalling), headquartered in Atlanta, Georgia with a European office in Sibiu, Romania. Founded in 2006, the company targets expatriates, immigrants, frequent international callers, and travelers with a portfolio of low-ticket prepaid services: Voice Credit (pay-per-minute international calls), Monthly Plans and a $10/month World Unlimited subscription covering 50+ countries, Mobile Recharge (prepaid top-up to 600+ operators across 160+ countries), Travel eSIM data packages in 190+ countries, and Virtual Numbers for receiving calls at local rates. Distribution is fully self-serve and digital, centered on the siguenllamando.com website and the KeepCalling mobile app on iOS and Android, supplemented by local access numbers in 35+ countries and a browser-based Web Call application. Payments are processed via PayPal, Apple Pay, Google Pay, and major card networks, with checkout supporting five currencies (AUD, CAD, EUR, GBP, USD).

Underlying technology is conventional VoIP for app-based calling and PSTN interconnect for access-number calling, paired with eSIM provisioning infrastructure supplied through partnerships with local mobile network operators (T-Mobile in the US, EE in the UK, Etisalat in the UAE, Turk Telekom in Turkey, and others). The platform does not expose a public API or SDK and shows no proprietary AI or ML capabilities; operational analytics rely on Firebase, and authentication is supported via social login through Facebook and Google. The company is privately held with 11-50 employees, no disclosed funding rounds, and no public revenue figure.

The business model combines four revenue mechanics: usage-based per-minute voice charges (with 1-minute rounding, no hidden fees, and a $5 minimum order), recurring monthly subscription fees for calling plans and virtual numbers, transactional take-rate fees on mobile recharges (minimum $1 processing fee), and one-time eSIM data package purchases. Customer acquisition is product-led and reliant on word-of-mouth within immigrant communities and traveler segments, supported by organic search, an email newsletter, and social media presence. The corporate footprint includes DBA brands KeepCalling and MobileRecharge.com, all consolidated under the Miron Enterprises parent entity.
