How to unlock your ZUK Z2
In this article, we’ll show you how to unlock your ZUK Z2.
What is a PIN?
Normally, you must enter your PIN to access the device after turning it on. A PIN code is a four-digit code and is used to ensure security so that everyone can not access your smartphone. This one, as well as your personal PUK (see below for more details) you receive when you purchase your SIM card in a cover letter.
In case of activation of the PIN code entry, you will only be able to use your smartphone if you have entered this code correctly. However, PIN entry can also be disabled.
How to unblock the SIM card on my ZUK Z2?
When you turn on your ZUK Z2, you must first enter the PIN code to unlock the SIM card. But what if you entered multiple incorrect code?
If you have entered the wrong code several times, a message asking to enter the PUK code will appear on the screen.
As already mentioned, it is also possible to disable the option that asks to enter the PIN. How it works is explained below:
To disable PIN entry
- Go to settings, then “Security”.
- You will now see several options. Click on “Configure SIM blocking”.
- If you had to enter a PIN code to access your ZUK Z2 so far, the option “Lock SIM card” is checked.
- Click to disable the option.
However, we recommend that you enter the PIN code for security reasons.
How to change your PIN
If you wish, you can easily change your PIN, for example, because it seems too simple and therefore not safe enough, or because you have noticed that other people know your PIN. To do this, please proceed as follows:
- Access settings in your ZUK Z2.
- Also, press the “Security” option.
- Click “Configure SIM Block”.
- You will now see the option “Change the PIN code of the SIM card”. Click on the option to select it.
- First enter your old PIN. Normally, you have three attempts to complete this step.
- Then follow the instructions on your phone to choose a new code.
If your SIM card is locked on your ZUK Z2
If you enter a wrong PIN several times, your SIM card will be locked and you will need to enter the PUK code to unlock it.
The PUK code is an eight-digit personal code that unlocks your SIM card. However, you can not change this code, as is the case with the PIN.
To enter the PUK code you have up to ten attempts. If you have not successfully entered the correct PUK code, your SIM card will be locked permanently.
If you have entered the PUK code correctly, you will be prompted to set a new PIN.
Attention: If you do not have your PUK code handy, for example because you can not find the additional letter of the SIM card, please contact the customer service of your mobile operator.
Make your ZUK Z2 “sim lock free”
In Europe, the providers have agreed that after one year the owner can request the unblocking code free of charge, with which the phone can be unlocked. In the meantime, too, but then the provider will usually demand a fee, because the economic ground for giving the discount has been lost. This should be the case on your ZUK Z2.
There are various possibilities to remove the SIM lock without permission from the provider, for example via an independent telecom shop, but there are potential disadvantages. For example, there is no certainty whether the phone is still doing well after removing the sim lock. Moreover, it is the provider that acts as supplier of the telephone and is therefore responsible for the warranty of the device. Unauthorized unlocking is usually considered by providers as a ground for exclusion of the guarantee. So please check your ZUK Z2 warranty before doing so.
Legal status if you decide to unlock your ZUK Z2
Incidentally, it is not forbidden to remove the sim lock in the meantime. After purchase, the device is the property of the buyer, who may make the choice to switch to another network. This is usually done by replacing or modifying the software, which is not prohibited if the adjuster or the client holds copyright or a license for the updated software.
Among other things, in a judgment of a Dutch court case the following has been released about the removal of the sim lock of mobile phones: “A sim lock and a service provider lock can not be regarded as copyrighted work.” and “Changing a sim lock or service provider lock, or the intrusion into such a facility is therefore not to be regarded as unlawful”. So check all these cases before unlocking your ZUK Z2!
