I was skeptical about using a service…
I was skeptical about using a service like this but had no real alternative as the Canadian mobile provider I use do not allow top ups using non- north American bank cards.
After some issues about the code provided by DrSIM their customer service resolved things to my complete satisfaction.
The customer service is extremely fast and efficient.
Excellent customer service and honest communication!
Unfortunately, my iPhone unlock was rejected due to carrier restrictions, but the doctorSIM team handling the situation was amazing. Even though they incur losses for failed attempts, they kindly offered and processed a full refund to ensure a positive customer experience. I truly appreciate their honesty, transparency, and top-notch customer service. Highly recommended!
Thank you
Thank you, DoctorSIM, for the fast and professional assistance. The verification process was clear, and the customer support team guided me throughout the process. I appreciate the security measures taken to protect customers. Great service!
