Hi. When I recently reviewed my previous bills, I found out that some of my add-ons have been automatically changed. For example, in the previous bill I have 2 add-ons called $12/Day US Easy Roam and $15/Day Easy Roam INTL, which has become Easy Roam US -- PayPerUse Access On and Easy Roam INTL -- PayPerUse Access On respectively. I wonder if they are the same add-ons just with different names or they are actually different. Thank you.
