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
Will unlocking my phone void the warranty?
No. Unlocking your phone with doctorSIM doesn’t affect the phone’s warranty because the software and hardware of the phone are unaltered during the process.
What do I need to unlock my Sendo?
You need your phone at hand and be able to access the keypad and dropdown menus. You will also need to be able to use one of our many payment methods and have an e-mail address where we can send you simple instructions to unlock your phone.
How many unlocking attempts does my Sendo phone have?
Sendo phones have unlimited unlocking attempts so you don’t need to worry about that part of the process. You can request your unlocking code by selecting the country and network provider the phone is locked to.
Do you issue refunds if the unlocking code doesn’t work?
At doctorSIM, we only work with professional service providers that guarantee a working unlocking code. On the rare occasions we cannot obtain an unlocking code for your Sendo, we will return your money. Click here for the full list of our security certificates.
Can I unlock my Sendo if it has been reported or on the blacklist?
Reports are additional security measures which prevent the phone being used normally and are not removed by unlocking the phone.
If your Sendo has been reported stolen, lost or due to unpaid bills, you should contact the network provider to which the phone is locked to remove the blocking. You can still unlock your phone with doctorSIM, but you will not be able to use it in the normal manner until it has been unblacklisted.
Can I unlock my phone with any network provider?
Yes. Our unlocking codes are permanent and valid for all network providers in all countries. Once you’ve unlocked your phone with doctorSIM you never have to worry about it again.
Can I unlock any model of Sendo phone?
doctorSIM can unlock all Sendo phone models. You don’t need to specify the exact model because the unlocking instructions are the same for all. Just make sure you note down the IMEI number correctly and specify the network provider the phone is locked to. This is easy and we’ll show you how when you request your unlocking code.
