How To Check If An iPhone Or Android Device Is Factory Unlocked Or Not

One of the perceived downsides of the smartphone industry is the monopolization of devices through carrier locking. At point of sale and when you sign up to a contract with a carrier, it’s understandable, but thereafter, getting a handset unlocked can be a trying, if not impossible process. If you want to check whether your device is unlocked for use on any network, a nifty online service completely has your back, and not only is the website incredibly easy to use, but if you’re on Android, there’s also an app available to download over at the Google Play Store. More details after the break.

There are many reasons why you may want to check whether your device is unlocked. It might just be that you’re curious, and wish to know that if you wanted to switch over to a different carrier, you could do so with minimal fuss. Alternatively, you may be looking to stick your handset on eBay, in which case, you would want to know whether the device was tied down or unlocked so you could accurately notify the prospective buyer. Also, as we know, unlocked devices are more valuable, and if every smartphone were unlocked forever, the world would be a better place.
