Can you bring an Android smartphone to Koodo Mobile?

[veronica]

Hi, I'm planning to buy an HTC Android smartphone, and I want to bring it to Koodo Mobile because the plans are much cheaper, plus I don't need a data plan because everywhere I go has Wi-Fi. Is it possible to buy the phone off of Kijiji or Craigslist or just at a Telus or Bell store, and get a SIM card from Koodo and just use Koodo's service?

Or is it possible just to buy an Android smartphone without a data plan with any other carrier?

Thanks for helping me if you do.
