HughPickens.com writes Andrew Moore-Crispin reports that beginning today, as result of an agreement major wireless carriers made with FCC Chairman Tom Wheeler in late 2013, wireless carriers in the US must unlock your phone as soon as a contract term is fulfilled if asked to do so unless a phone is connected in some way to an account that owes the carrier money. Carriers must also post unlocking policies on their websites (here are links for AT&T, Verizon, Sprint, and T-Mobile), provide notice to customers when their devices are eligible for unlocking, respond to unlock requests within two business days, and unlock devices for deployed military personnel. So why unlock your phone? Unlocking a phone allows it to be used on any compatible network, regardless of carrier which could result in significant savings. Or you could go with an MVNO, stay on the same network, and pay much less for the same cellular service.
