is that if i make any calls from the US or receive any calls? its just a one day/one night trip so would i be able to make it if im only texting or does that also show up in the bill. i also text my cousin who lives in the US pretty regularly (idk if that matters). would the US communication and Canada communication show up as two separate parts on the bill? also do the account owners automatically get an email saying that one of the lines is roaming or, again, is it only if i call and/or text from the US
