So, the time is getting closer for my smartphone upgrade, likely in May when work becomes more steady. As I'm looking at potential upgrades, I'm wondering, can I swap between my old phone and new phone as often or whenever I wish? Do I have to let Koodo know when I am switching? The reason being I'm not sure my wife will like a bigger phone and may wish to use our old phone. She hates complication and all kinds of apps on the phone as it is, and I could easily strip down the Galaxy Ace bare for her to use, and set up mine for my use. Will it be a problem to do something like this, and swap the Sim to her phone whenever she needs to use it, then back to mine?
