FAQ - Jailbreak Unlock

How does the unlocking work?

This type of unlocking is carried out through Jailbreak. What is Jailbreak? Jailbreak is a software that removes restrictions from devices running iOS operating system (the iPhone operating system).

Installing Jailbreak and completing the process is very simple:

  • We will send you a software that installs Jailbreak on your iPhone easily, securely and without losing or damaging any data on your phone.
  • The unlocking will be carried out through an option in this software. Your phone's IMEI will be registered on our servers so that you can complete the unlock whenever you want, as it will have no expiration date.

PLEASE NOTE: This software will unlock your iPhone's network so that you can use it with any carrier worldwide, but it will NOT remove the iPhone’s IMEI from the blacklist if it was reported lost, unpaid or stolen.


Is it safe?

Yes. The unlocking tool that we use at doctorSIM is totally safe, as long as you follow the steps as indicated in the unlocking tutorial. Also, make sure you double check that your iPhone model and its version of iOS are supported by the software.

  • Supported iPhones: SE, 6, 6S, 7, 7 Plus, 8, 8 Plus and X.
  • Supported iOS versions: 12 to 14.8.1

To check your iPhone model, as well as its version of iOS, just follow this path: Settings> General> About. There you will be able to see both your version of iOS and the exact model of iPhone you have in your hands.

At doctorSIM we take the security of your phone very seriously, so after thoroughly researching all the Jailbreak alternatives available on the market, we offer you this one because we know it’s the safest.

If my version of iOS is newer than the supported versions of iOS, can I upgrade to a previous version in order to jailbreak my iPhone?

Yes. This is known as 'downgrade': the procedure through which we will move from a more updated version of iOS to an earlier version.

This process is usually performed when an iPhone does not work properly with an operating system update and the user decides to return to a previous version.

Provided that your iPhone model is supported, jailbreaking your phone will be possible as long as you go back to a previous version of iOS (remember: between version 12 and 14.8.1) if you had previously updated to a higher version of iOS.  


Will I lose my iPhone data?

No. If you use the software we sent you and follow our guidelines, your iPhone data will be safe. However, as a precaution, at doctorSIM we always recommend backing up all your data, photos and files before jailbreaking your iPhone.


Will I be able to update iOS once I finish jailbreaking my phone?

Technically, yes, but keep in mind that if you upgrade to a later version than the one you had when you unlocked your phone, you will lose the unlocking. 

This unlocking software is designed for specific versions of iOS and any updates will cause Jailbreak to not work properly.



Will I have limitations on my iPhone if I jailbreak it?

You won't have any limitations, quite the opposite!

Jailbreaking will allow you to further customize your iPhone and download all the apps that are not available in the Apple Store. You will be able to get many more applications through Cydia, the app for downloading other apps that will be automatically installed on your iPhone when we jailbreak it. Tons of new applications are waiting for you!

Plus, all the apps you already had installed before jailbreaking will remain on your phone, including the Apple Store app, in case you need to use it at some point.



Will I lose my warranty?

Don't worry, jailbreaking does not invalidate your iPhone warranty. If you need a repair in the future, the only thing you’ll need is restoring the device to factory default in order to return to the original operating system.

Can I remove the Jailbreak?

Of course you can. You’ll simply need to restore your iPhone to factory default. That way you will be able to use your iPhone with its original operating system. Please note that if you remove the Jailbreak you will lose the network unlock of your iPhone and you’ll only be able to use it with the original carrier (the one you purchased it through).
