Asking for my daughter who is oversees and having problem with text charges. She can't call she's on structured trip. We are both with Koodo. Bought 2 international Add ons. Saying all texts used but didnt send that many. Then charged overage for some texts but not others. Why? What is character limit for international text? Why show message sent 6 times to same number? It wasn't that long and only sent once and only received once.
