If you redeem another Mega Plan value before your current 30-day plan expires, don’t worry, you don’t lose out. Any additional Mega Plan values you redeem within your current period will be added to your existing plan, so if you have 10 days left on your current plan and redeem another Mega Plan value you will have access to Unlimited services for 40 days. Plus, any unused credit for additional services will be rolled over to your new expiry.
