Founded in 2007, doctorSIM was born from sheer frustation! Our relationships with our CellPhone Network Operators have been dominated by chaos and lack of transparency.

doctorSIM is a global attempt to bring clarity and return power to the consumer by helping you save on your phone bill via intelligent rate plan optimisation algorithms and assisted services such as Phone Unlocking. You deserve to pay only for what you use, feel free to choose how you use your phone with any network carrier and do it according to your rules.

Currently offering worldwide unlocking services, its savings engine, currently operational in Spain and LatinAmerica, will rollout in the US in Q4 2013.

doctorSIM is fully independent in its mobile network plan recommendations.

Over 600,000 people have already regained control of the relationship with their network carrier thanks to doctorSIM
