GalaxSim Unlock

Easily sim unlock your Samsung Galaxy family smartphone/tablet (S, S2, S3, Tab, Tab2, Note, Note2 and variants) so you can use any other network operator. As simple as one button click, and you can change your carrier sim card !
GalaxSim Unlock is currently the only app that can unlock recent GS2 and GS3 firmware without relocking upon reboot (even with recent ICS or JB roms).
* Please note that due to different hardware, US Qualcomm based GS3 (SGH-T999, SCH-I535, SCH-R530, SPH-L710, SGH-I747…) are currently not supported. Don’t leave bad feedback, I can’t do much without one of these phones in my hands ! *

Major functions:
- Sim Unlock your phone (in-app payment)
- Backup and Restore EFS folder (free)
- Give you detailed information about your current and previous nv/lock state.

Features:
* unsimlock/unbrand your phone
* work on any rooted rom (samsung, aosp, aokp, cm9, cm10…)
* support international GS3 GT-I9300
* support other Galaxy family devices (S, S2, Tab, Note and their variants)

* give information about previous (stock) simlock status
* backup efs before any modification (should guarantee a safe use)
* restore your efs backup on demand
* compute md5 files properly (no log hack)
* support more Galaxy devices soon

How to use :
* be sure your rom is rooted (tutorial links included for major devices)
* click on “unlock” button
* reboot

Notes :
* If other carriers’ sim cards are still refused after a successfull unlock, your phone might be “hardlocked” by your carrier and require a full unbranded rom flash (only seen on Telcel and Claro so far).
* Free download and in-app billing to unlock is used so that you only pay if your device can really be unlocked. The backup/restore feature is free and will stay free. Price displayed before order. Buy once, illimited use.
* Although I made my best for this app to be safe and it’s been successfully used by more than 7000 users already, remember that there are some risks inherent to unlocking devices. I shall not be held responsible in any way if anything goes wrong using this app.
* Please note that due to a large variety of Galaxy devices, it has not been extensively tested on every available model.
