Cricket's free phones are advertised on its website, although brick-and-mortar stores generally offer the same deals. However, free phones typically require activation fees and mail-in rebates, so they cost money upfront.
Cricket's service plans change frequently, as do the phones it offers at different price ranges. Because Cricket offers no-contract plans, its cellphone discounts aren't as high as what is typically offered by plans with contracts. However, users don't have to pay extra per month for their phones and can quit their plans at any time. As of 2015, Cricket is owned by AT&T, so its phones typically use the same frequencies. If the phone can be unlocked, a Cricket phone can work with AT&T service plans.
