When you purchase a phone through T-Mobile, it’s often subsidized, meaning you get a lower initial price but commit to a contract. This is like signing a business deal: T-Mobile wants to ensure they recoup their investment. If you decide to leave early or switch providers, unlocking allows you to break those chains, legally, we promise. Most carriers, including T-Mobile, have guidelines for unlocking devices, which we’ll cover shortly.
