It was pretty easy. Waited a little longer than I wanted to but that’s ok. I am still very pleased with the service especially being from a small country. Keep up the good work !
Satisfied Customer. I am not too hot on technology and I booked my appointment at an inconvenient time for the technician. But he dealt with me efficiently and patiently which I really appreciate. Go...
DoctorSIM Is one of my favorite unlocking sources. They’re experts that know exactly what they’re doing and walk you through the process to get the job done. Thank you very much for your support!
