Unlocked cell phones can be purchased from places online, such as Amazon, Best Buy, Overstock and Wal-Mart, among others. Because the phones are unlocked to work with any cell carrier, they are usually more expensive than those that come with a contract.
Most cell phone manufacturers release unlocked versions of their phones. Shopping at these and other online retailers, shoppers can find phones like the iPhone, Amazon Fire, Samsung Galaxy S5 and S6 and the Nokia Lumia unlocked for use with any carrier.
Prices at these online stores vary and shoppers can often find older models at a more reasonable price than more recent models.
