Very good article.
ReplyDeleteI too like to share my knowledge about unlocking Samsung Galaxy phones.
Samsung Galaxy S4 can be unlocked safely ,easily and permanently using unlock code . We can get the unlock code from our service provider or from online sites like Unlock-Zone.com . This method of using unlock codes to unlock the phone won't void its warranty. Whereas using software and applications to unlock will void the warranty and may damage the phone permanently if not used properly.
