What's the best place to get a GSM unlocked phone?
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.
What does it mean if a phone is unlocked for GSM networks?
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.
The Best Deals on Unlocked GSM Phones
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?
