Forgotten your Screen Time passcode? Restricted by a Mobile Device Management (MDM) profile from an old job? MobiUnlock can remove those restrictions.

The Catch: This is premium software. While a free trial exists, it usually only allows you to detect your device. To actually remove the lock, you need the full version—and that requires an activation key (license code).

The most dangerous outcome. To find a "working key," you download a crack.exe or keygen.zip. These files are frequently loaded with:

If problems persist, contact EaseUS support with your order number and screenshots of the error.

Never use pirated activation keys or keygens. Using unauthorized keys is illegal and unsafe — they can contain malware, break the software, and prevent support or updates.

Even with a genuine key, errors occur. Here is the fix for the top three error messages:

Error 1: "Invalid license code"

Error 2: "Activation limit exceeded"

Error 3: "Network connection failed"

Follow EaseUS on social media (Twitter, Facebook, or Reddit r/software). During holidays (Black Friday, Cyber Monday, Christmas), they often run giveaways for 5-10 free genuine keys. You have to be fast, but they are real.

If you buy a second-hand phone and the previous owner forgot to remove their Apple ID, you have a brick. MobiUnlock can remove the activation lock, allowing you to sign in with a new Apple ID.
