How to unlock Samsung GT-I9505 Galaxy S4

How to unlock Samsung GT-I9505 Galaxy S4


Having a locked device in a specific network can be very annoying especially if we didn’t choose this network. In addition, the locked devices are cheaper when you want to sell them. In most cases, the mobile operator allows you to unlock your phone for an amount of money, but that doesn’t happen in all cases. However, you will have a greater satisfaction if you will succeed to unlock your phone by yourself. In addition you will save some money.

Those from Samsung are more relaxed and allows users to unlock their own devices as long as they follow some simple steps.

Before you start, remember that it is a little more delicate operation than a common one and you follow these instructions at your own risk.

In addition, this method only applies to GT-I9505 and not for other versions of Galaxy S4.


Spapp Monitoring works on both locked or unlocked phones. Please check some of the new features of our Spy App for Android: Facebook Spy, Whatsapp Spy tool, Whatsapp hack tool, Snapchat Spy, Instagram spy, Telegram Spy, Phone Tapping, Spy camera app, Call recorder spy or Sms spy.
