What doctorSIM does
doctorSIM Mobile S.L. is a Spain-incorporated (Madrid) consumer-facing digital services platform operating under a product-led growth model since 2006. The company operates a self-serve e-commerce storefront and native iOS/Android applications that enable international mobile airtime top-ups, digital gift card purchases, phone carrier unlocking, and IMEI-based phone diagnostic checks. Underlying technology is an integration-and-routing platform that connects consumers to telecom operator back-end systems across multiple countries, paired with digital gift card distribution and an IMEI lookup service spanning blacklist status, original operator, iCloud/Mi Account activation, unlock eligibility, and warranty verification.
The business model is transaction-based across four revenue streams — international mobile top-ups, digital gift cards, phone unlocking, and IMEI check services — each generating fees or margins per transaction. Customers are individual consumers distributed globally with concentrations in Mexico, Venezuela, Dominican Republic, Colombia, the United States, and Nigeria; no enterprise or B2B contracts are disclosed. Marketing relies on organic social channels, content marketing via the doctorSIM blog, and review-platform trust signals (4.7/5 across 26,000+ Google and Trustpilot reviews). The company is privately held with no disclosed institutional investors, funding rounds, or M&A activity, and is led by co-founders Hugo Meana (CEO) and Lidia Meana (COO).
