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!
Video: How to unlock a phone
Do I need to know the exact model of my ZTE?
It is not necessary to know the exact model of your ZTE to unlock it by IMEI with doctorSIM. Whether your phone is a ZTE Blade, ZTE Skate, ZTE Grand, ZTE Axon or any other model new or old, we can unlock it for you at doctorSIM.
I don?t know to which network provider my phone is locked. Can I still unlock my ZTE?
Yes. Just select a network provider from any country because the unlocking instructions you?ll receive by e-mail are the same for all.
How do I know if my ZTE has unlocking attempts remaining?
Unlike other makes, ZTE phones have unlimited unlocking attempts which means one less thing to worry about during the unlocking process. However, we recommend you request your unlocking code from a reputable unlocking service provider, avoiding codes supplied for free, as these incorrect codes may actually damage your ZTE. At doctorSIM, we offer a 100% guarantee which means we will return your money if you are not completely satisfied with our service.
