An upgrade is a long-term reward that boosts your plan every month, like additional mobile data or a monthly rebate on the price of your Home Internet plan.
Every upgrade is valid for two (2) years starting from the date you receive it (whether you apply it to your plan or not). So, keep an eye out and activate your upgrades as soon as possible to fully take advantage of them.
