We will add a 1GB data bolt-on to your plan automatically each time your data is fully depleted; this will be added up to 5 times per plan cycle. Each 1GB data bolt-on costs $8. The maximum charge you can incur for automatic data bolt-ons is $40 per plan cycle. After the 5th automatic data bolt-on has been depleted, data will be blocked and you can choose to purchase ad-hoc 1GB data bolt-ons if you wish.
All data will expire upon your monthly renewal date, so if for example, an automatic data bolt-on is added 4 days prior to your renewal date, you will only have 4 days to use the data and then it will expire when your plan is renewed.
