I will be traveling outside of Canada and at least need to be able to send & receive text messages en route so I plan to add the 30days international text roaming add-on. After that I plan to cancel my subscription. I am the account holder and there are two subscribers -- me and my husband. My FIRST question is how will I be able to cancel my subscription while I am physically not in Canada. SECOND, can we still keep my husband's subscription even with mine being cancelled?
