We believe that Back Market is the best place to get an unlocked GSM phone because our phones are much cheaper than newer editions, yet still have the same quality that you can expect out of the box.
It's actually pretty simple, since T-Mobile and AT&T use GSM technology to transmit their cell signals, phones that are able to work with both of these carriers are often called GSM unlocked phones. It's also important to mention that GSM unlocked phones are likely to work on foreign carriers, since most international cell providers also use GSM technology to transmit their cell frequencies.
We don't mean to brag, but we feel we have some of the best deals on unlocked GSM cell phones. Why do we feel this way? Because our phones have been refurbished, they are just a hair more expensive than regular used phones, but come with the same quality as new devices. Pretty cool, huh?
Be on the lookout for special events and pay attention to the top featured product on each of our categories, these are most often the best deal according to our algorithm!
