Hello, I am at the end of my wits to get my phone work with Koodo. I arrived to Canada few days ago with my iPhone 4 from Czech Republic. I bought a koodo prepaid sim, put it in my phone but all I get is no service message. I tried everything I could find or think of. I checked that 3g is enabled, it was. Then I restarted and reset the phone to factory settings, then I updated to iOS 7 through itunes and then again i reset the network settings just for the kicks. I checked the IMEI on this page http://iphoneimei.info/, it says the phone is unlocked and last activated sim is Telus Canada. When I try to select carrier manually, there is only one option, it used to be rogers but now it just says 302720 which I believe is code for Rogers. The original O2 sim has no trouble connecting to Rogers network when I put it back in again. Do you know what could be the source of my troubles? Or how to fix this issue?
