Samsung Galaxy S5 has been arrived.

The Samsung Galaxy S5 is now available in 125 countries worldwide, and early adopters are realizing that the device also has a region lock, a feature which was introduced on the Samsung Galaxy Note 3 last September.

Region locking is a restriction manufacturers place on electronics to prevent their use and sale outside of the region in which they were originally purchased. To region unlock the Samsung Galaxy S5 for use outside of its country of purchase, users must first install a SIM card from a mobile network within their sanctioned region and then make phone calls for at least five minutes before the device is open to use with SIM cards from other regions.
