Since my phone service will be prepaid, there is no refund on any service payments. However, for customers that trust in the quality of service can opt to pay for 1 year ahead. In turn, they will get 2 months off. Therefore if the monthly plan is $35, the annual plan will be $350. Adding add-ons, or upgrades will be pro-rated without any discount. Downgrades will take effect in the next billing cycle.
