Excellent customer service
I used the service to recharge a number in Congo but unfortunately, the operator was not available. However, I made the payment but the fast and efficient support was very clear and I received my refund with no problem. If I need a recharge for another operator or country, I will use the service again with no doubt. Great service and support, thanks.

Hello,
Thank you so much for sharing your experience in such detail. We regret that the operator in Congo was unavailable at the time, but we're happy to know that our support team was able to resolve the refund quickly and transparently. For us, customer trust is paramount, even when things don't go perfectly the first time.
We'd be happy to assist you again with any top-ups or other requests you may have in the future. Thank you for trusting us!

Need a free unlock

Unprompted review
Reply from doctorSIM
Hello,
We understand you'd like to receive the service free of charge, but to guarantee a safe and legal unlock that doesn't void your device's warranty, we need to perform technical processes that incur an operating cost. At doctorSIM, we focus on providing a professional and guaranteed service so your phone is permanently unlocked without errors.
If you change your mind, we'd be happy to help you with the process.
Best regards,
Adrián
