By accepting this Instant Savings Discount, you agree to repay $200 of this discount ($300 for smartphones and netbooks) and authorize us to charge your credit card in repayment of this amount if, during the 181 days after your new equipment is activated, your wireless carrier notifies us that the services you purchased have been suspended, disconnected, or deactivated, or if you return your purchase outside of the return and exchange provisions of our 30-day Satisfaction Guarantee.
Please note some of the reasons your wireless carrier may notify us of a deactivation include if:
* You transfer this equipment to another carrier line of service after it is activated
* You change your rate plan to a lower monthly service rate than was specifically required at the point of purchase
* You deactivate texting/data features that were specifically required at the point of purchase
* The new line of service activated with your order is used to replace a pre-existing account
