Quote:As of today, all of the major wireless companies in the US have promised to abide by policy agreements laid down by the Cellular Telecommunications Industry Association (CTIA) regarding device unlocking. These guidelines, first proposed in 2013, require carriers to disclose their policies on prepaid and postpaid device unlocking, offer unlocks to all owners of postpaid devices and prepaid devices after one year, to notify customers when their hardware qualifies for unlocking, to respond within two business days to requests for an unlock, and to unlock devices for deployed military personnel.
