Fulfillment of Service Commitment. You have received certain benefits from us in exchange for your Service Commitment, which may include, but are not limited to, a subsidized wireless device. There are two alternative ways to fulfill your Service Commitment. You can pay for the Services described in your Customer Service Summary for the term of your Service Commitment, or you can terminate your Agreement prior to the end of your Service Commitment and pay an Early Termination Fee (ETF). The Early Termination Fee is not a penalty, but rather is an alternative means for you to perform your obligations under the Agreement that partially compensates us for the fact that the Service Commitment on which your rate plan is based was not completed.
