Delivery Reports

Just wondering if someone can confirm on EE pay monthly, do you get charged for delivery reports? Read somewhere in forums that it's free by an employee and lots of places they say there is a charge. Sometimes when getting a new phone or ROM sms receipts are automatically turned on and I forget to check.
With the newer phones these days you don't get texts back saying "Delivered" or anything and you just get a little tick or delivered etc in the actual message, so wondering if that does get charged?
