I went to upgrade my phone with another carrier, they told me I couldnt upgrade due to payments not being on time. I had a broken phone, and a cellphone bill to boot. I went into the wireless store at walmart. Looking for an unlocked phone, the lady asked what was going on, she said let me run you through koodo. Instantly approved, have no idea why my previous carrier didnt want to help me. They ported over my number, now I am with koodo and so far I love it. You fixed my day, I went from disappointed to really excited. The Galaxy s4 is probably one of the best phones I ever used. Thank you koodo!
