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.
