Yes! You can use your positive Tab balance towards a new phone. For example, if you have a positive Tab balance of +50 and qualify for Tab, you have up to $410 (+50 plus up to 360 on the Tab) to use towards a new phone! It is important to note that once you upgrade to the new Tab, you will no longer be accumulating a positive Tab. Instead, you will have access to new Canada-wide plans that are less expensive.
