Who we are

The Company

Founded in 2007, doctorSIM is an Internet-based technology company that provides a wide range of savings solutions for digital gifts, the cell phone industry and the premier unlocking company in the world. Our mission is to support the user by providing clarity in an industry dominated by chaos and a lack of transparency.

In short, providing the solutions necessary for the user to take full control of their expenses and their cell phone from the network providers and phone manufacturers.

doctorSIM provides phone unlocking services which allow users to use their cell phone on any compatible network in the world. Freedom to choose network carriers has multiple benefits primarily saving money in the long run.

Complementing these unlocking services are IMEI phone checks, top-up services for networks located in over 200 countries, comparison tools for managing and calculating savings on monthly phone bills and repairs for all phone manufacturers.
