AT&T and Sprint join T-Mobile with free 32GB Apple iPhone 7 offers13
Sprint's deal also requires you to lay out the money in advance for the free handset. New and existing Sprint customers can trade in an Apple iPhone 6, Apple iPhone 6 Plus, Apple iPhone 6s, Apple iPhone 6s Plus, Samsung Galaxy S7 and Samsung Galaxy S7 edge in working condition, and receive a free 32GB Apple iPhone 7. The offer is available with a new activation or with an upgrade, and reimburses Sprint customers with a monthly $27.09 service credit over two years.
AT&T's deal isn't limited to the iPhone 7, although you can certainly select it if you so choose. Starting tomorrow, if you are a new or existing DIRECTV or AT&T subscriber, move over your account from an existing carrier. Do that, and you will be eligible to get reimbursed up to $695 in monthly service credits for the smartphone of your choice. Of course, you will be required to lay out the money needed to buy the phone in the first place. Business customers will receive an additional $200 per line that is switched.
If you don't mind laying out the money for a new iPhone 7 in advance, T-Mobile, AT&T and Sprint are giving you the opportunity to get that money back in two years. If one were a cynical person, he or she might say that the carriers are still offering two-year contracts albeit in another form.
