MMS may show as data being used on your phone's data tracker but Koodo doesn't count it towards your data usage on self serve. As well, you may subsequently end up using data on background applications while turning it on to send MMS.
Ok, so even when I am connected to wifi, and turned my mobile data on, , it showed I used 1 MB to send a text attaching 2 pictures. How do I know how much is charged to my 2 GB of free data? Why is it using data when I am connected to wifi when I turned my mobile data on? Does my mobile data need to be turned on when I send a text with a pic attached?
