DoctorSim Team customer care is top-class

I’ve been using DoctorSim.com for a while now, and they truly make the whole process of mobile top-ups and remittances incredibly easy and stress-free.
​What really stands out is their team—everyone I’ve interacted with is so friendly, approachable, and always genuinely ready to help if you have a question. It’s rare to find that level of personalized service online! Plus, the speed is fantastic; every time I’ve made a payment, the process was completely finished in just a few minutes.
​It’s such a reliable service. Keep up the great work, DoctorSim!

Will the warranty be void? Could the phone be damaged?

If you unlock your HTC by IMEI with doctorSIM, your warranty will remain intact. It is the only unlocking method recommended by manufacturers, as it does not damage the hardware or software. The phone will be in the same condition as it was before unlocking.

How to find out if an IMEI is blocked

If you suspect that your HTC is reported, we recommend that you contact the original operator to verify this. Remember that this is an additional security mechanism that unlocking does not remove.

How long does the release take?

The guaranteed delivery time depends on the country and delivery operator. You can check this when selecting these details, although we will always try to deliver the instructions as soon as possible. When you fill out the form, you can also check the average delivery time for the requested service.

Is the unlock permanent? What happens if the phone asks me for the unlock code again in the future?

doctorSIM's IMEI unlocks are permanent. You will never lose them, even if you restore your HTC to factory settings, the unlock will remain. In the unlikely event that your phone asks you for the code again, you will only need to enter it again, as it does not expire.

How can I pay for the release?

There are multiple payment methods available for your country in step three of the release request. Here you can find additional information about those you are unfamiliar with.
