I just activated a Koodo prepaid plan with $15 base plan, 1GB data booster, and a couple of talk boosters (625 mins total). I followed the instructions online and set up the APN in my phone (it's an iPhone 5). But now, when I go to SMS anyone, it says that it sends but they never receive it! It's really odd because I never get any error messages or incoming texts. However, data and calling works fine. Has anyone had this problem before?
