Get your Samsung Galaxy S4 unlocked to use it on other carriers!
You may have heard about this thing called “unlocking” your phone. For the tech-savvy, this is pretty standard stuff, but for everyone else, let us outline the basics of what phone unlocking is, why you might want to do it, and how to go about it.
When you buy a phone from a carrier like AT&T, Vodafone, or Rogers, they give you a SIM card with all of your relevant account information on it. The phone you get from that carrier won’t be able to make calls or sends texts until the SIM card is installed in your phone. Getting data for web browsing and apps is only possible over Wi-Fi without a SIM card installed.
