How it's Done

Being one of the first Samsung phone models with Multiview and Dual Camera with dual Shot the S4 is said to be the final phone developed by Samsung in Apple's wake... Yes yes , that's all great but my S4 happens to be locked and won't accept the SIM card from the carrier I want to use.

We hear you .. Can you unlock it ?

Mais oui, and it's easy, using unlock codes. Not like rocket science codes, but plain and simple digits , read 0-9 , that you dial into your S4 through it's touch screen and voila ! It all of sudden accepts the SIM that it was not accepting 30 seconds ago.

Voodoo ? Nope ! Guaranteed product...

    I unlock my USA AT&T Samsung Galaxy S4 with GSMLiberty code. All I did was put in my new SIM card from T Mobile and input the network unlock code acquired from GSMLiberty. I messed up inputting the unlock code the first time around, but was successful when I input the code correctly. This was a great purchase and extremely easy to execute. I received the code extremely quickly, within 2 hours.

    Samsung Galaxy S4 SGH-I337M, Locked to Fido. Unlock with using Virgin Mobile Sim card. Successfully unlocked in 5 seconds. Thanks to GSMLiberty for the great service. In the product page, it says processing time is between 7-8 hrs. Please be patient because it could take a bit longer than this, but definitely you will get your code that works, which is worth waiting for. :) This is my third time unlocking a device with I have helped my friends to unlock as well, they all worked perfectly. Sorry, has big background noises because my dog was barking, I had to mute the video
