Instant Samsung SIM Unlock for Global Use—Fast, Safe & Root-Friendly

Unlock your Samsung Galaxy smartphone or tablet in just one tap and switch freely between carriers worldwide. This simple, reliable tool removes SIM restrictions on supported Galaxy models without needing an unlock code on most devices. Perfect for travelers, frequent SIM swappers, and users looking to maximize their device freedom with fast mobile network switching, international carrier compatibility, and secure EFS protection.

GalaxSim Unlock is the only app that instantly and successfully unlocks new Galaxy devices, including models running recent ICS or JB ROMs. Your GS2, GS3, GS4, or Note2 remains unlocked even after reboot. It includes backup and restore tools, lock-state insights, and support for rooted ROMs—ideal for users managing advanced setups, custom ROMs, and multi-network usage.

*Please note: Many LTE/4G devices aren’t supported yet. Some SGS3, SGS4, and Note2 devices with recent ROM updates use new lock systems that currently can’t be unlocked. We’re working on it, as this requires time and access to locked devices!*
