I have an old plan, CAN Data 1 GB Unlimited Min, which has unlimited SMS and MMS. I recently texted someone in the US and was looking at my usage on Self Serve and was wondering why the US text messages were categorized separately from the other text messages I received and sent. For example it says I sent and received 150 text messages in one spot and then it says 4 US text messages in another. According to my Self Serve I'm not being charged anything for the 4 US text messages but I know that can change. I just want to make sure I won't get charged. So if anyone can help me on this it would be greatly appreciated.
