We are currently visiting in the US. Before entering the US, we turned off our cellular data and roaming and we have not texted or called or checked voice messages. I tried the Koodo Chat assistant and it doesn't understand what I need help with. I requested a callback, but the response is that they don’t make international calls. So how do I get this rectified? We’ll be here in the US for a bit longer. How can I avoid having this happen again. Does Koodo just randomly tack on roaming charges for no reason?
