If bundles are changed mid-month then the allowance will pro-rate, for example, if a customer is on a 20GB plan and upgrades to a 50GB plan on the 15th of the month the allowance calculates as follows. 20GB divided by 30 days (full month) multiplied by 15 (days the customer had the bundle) to give 10GB for the first 15 days. Then 50GB divided by 30 days (full month) multiplied by 15 (days the customer has left in the month for the upgrade) to give 25GB for the last 15 days, 35GB in total.
