I'm planning on getting a new phone, probably the iPhone 5 SE. I am currently with Koodo, and have just recently paid off my tab for my current phone (Moto G 1st gen). I have a really old plan, only $20/month - and I don't want to change it. I want to know if I upgrade to the new phone on a new tab (not the Tab Plus) will I have to change the plan I have right now? Thanks!
