WipeLock.com aims to help people remove iCloud lock, SIM lock, lock screen from Mobile devices. However, creating a site like this can take a lot of time, money and work hours. If it works for you, I would appreciate it if you can donate a few dollars to offset the costs of writing and maintaining it!
You can make a one-off donation with PayPal: https://www.paypal.me/wipelockad.
Fewer than 0.2% of people who donate anything, so your support is really appreciated.
