Just moved to Koodo prepaid from Rogers and everything works fine except tethering. It worked fine with Rogers and my APN setting is correct according to Koodo tech support (not offering any additional help because my phone is non-Koodo phone). I have an unlocked SGH - I317M. Othere devices get connected to my phone, but no data is flowing. Searched the net and a few reporting the same problem without any clear solution. Does anyone know how to resolve this?
