Refund Policy

Customers have frequently expressed their dissatisfaction with DoctorSIM regarding the lack of refunds in the event of issues. Although the company has a refund policy that is clearly stated on its website, many people tend to overlook the details. Therefore, we have simplified the process for you below to help you understand how to obtain a refund and the necessary steps to take if you encounter any problems.

How To Get A Refund

DoctorSIM offers refunds for only two types of scenarios. They are as follows:

1. The unlock code does not exist.

If the unlock code for your phone is not available and you followed their guidelines, doctorSIM will refund your money.

2. Incorrect unlock code and/or instructions.

Video proof will be required if the unlock code does not work. The client must send an uncut video dialing *#06# to display the IMEI on the phone and typing the unlock code provided by doctorSIM. The image must be sharp enough to show the keys, display screen texts clearly and should show the device at all times. The video helps doctorSIM detect errors during the unlocking process. In these cases, doctorSIM will contact the customer via e-mail to solve the problem. Otherwise, if the unlock code happens to be incorrect, doctorSIM will request a second code free of charge or issue a refund.

DoctorSIM’s refunds will be processed within 2-3 business days. 

No Refund Scenarios 

DoctorSIM’s refund policy details cases where they WILL NOT issue you a refund. Please make sure to read carefully before ordering from them:

  1. Blacklisted, Reported or Blocked phones — These phones will remain inoperable despite any attempt to unlock them. If you have found or bought a phone from a stranger, make sure it has not been blacklisted/reported or blocked before requesting an unlock code. doctorSIM will not issue refunds for such phones.
  2. No Remaining Unlocking Attempts — Some phones have limited unlocked attempts. Once these have been exhausted unlocking the phone via IMEI will not be possible unless the counter is reset. This reset is not always possible for some phones. We recommend our customers contact doctorSIM before exhausting unlocking attempts to find alternative solutions. doctorSIM will not issue refunds if the phone has exhausted its unlocking attempts but will try to solve the problem for the customer.
  3. Free/Unlocked Devices — If your phone is already unlocked, they will not issue a refund. Make sure your phone is locked and in need of their specific services.
  4. Placing orders with wrong information — Requests with the wrong IMEI number, serial number, make, model, network provider or e-mail address will not be refunded. Please check the details of your request before checkout.
  5. Software and/or hardware modifications — Any sort of modification to the original software and hardware settings of the phone that might interfere with the functioning of the unlock code and instructions supplied by doctorSIM.
  6. Same unlocking request placed with another unlocking company or the original network carrier — DoctorSIM will not issue refunds if you have placed the same request in parallel with another unlocking company or the original network carrier. Processing a request incurs an internal cost to doctorSIM which cannot be reclaimed after the 10-minute grace period we offer to cancel or modify requests has expired.

Is Doctor SIM safe?

Yes, DoctorSIM is safe to use and do business with. They have been around since 2007 and has unlocked over 5 millions phones. They’re based in Spain and are fairly transparent. All services are remote and do not require physical or virtual access to your phone —  it’s all done from the carrier’s side. They guarantee that all services they offer are legal, safe and will not void your warranty. 

Does DoctorSIM unlock blacklisted phones?

No, DoctorSIM cannot unlock or clean blacklisted phones. You should note that DoctorsSIM cannot delete any phones from the blacklist status. Until the legal owner has resolved the problem, which led to the phone’s initial report, it will be banned from the Blacklist.

Rated 1.0 out of 5

Doctor sim confirmed in prior ability to unlock the phone. What I got instead was a message with useless information and no unlock code. This can also be called fraudulent intent.
