I currently am using a phone that I bought about 3 years ago and I am thinking of upgrading it. The plan I have right now is from the old tab system which has me pay $30 per month for 200mb of data and unlimited calling and texting. I am very satisfied with this plan and would like to keep it. Since my tab balance currently shows $0.00, does this mean that I should be able to buy a new phone from Koodo and continue paying $30 per month? For example, if I wanted to buy the LG G3, could I pay the retail price of $360 and use it with the same plan I had? Because of the change in the tab system, I am assuming that if I wanted to get the G3 for $0, I would have to get a new plan and pay $15 per month for 24 months as a Tab Charge, right? Does paying retail price for a phone allow me to keep my old plan?
