Sprint offers 1 year of free service to students who buy unsubsidized devices4
The deal runs in Best Buy stores and is only for Sprint phones and only for students. Anyone actively enrolled in a U.S.-based elementary, middle school, high school, college, university or accredited institute would qualify. You’d also need to provide proof of student eligibility.
Most devices that are available are sold unlocked, so after your 1-year contract expires you can continue using them on a different carrier. In order to do that, though, you should not forget to cancel right before the first year finishes. Finally, let’s make it clear that Sprint and Best Buy will not match prices on these phones as this is a special offer. Hit the link below to learn more or just visit a Best Buy store to get it.
