Ever since porting the number to Koodo last Saturday, I have been unable to receive calls. I can easily send and receive texts, connect to the internet, and MAKE outgoing calls, but not receive incoming calls, from anyone. I've tried from a mobile phone, a landline and a Google number. Plus, a few of my contacts have told me they haven't been able to reach me. The phone does not report any missed calls, either. iPhone 4. A phone malfunction is doubtful, because the phone worked fine before on the previous service provider. No, it's not incompatible bands; it was once a Telus phone, it has recently been unlocked, and it even works on Chatr. I've also tried resetting the network settings and then resetting all settings on the phone. Nothing. I've even activated the voicemail. The strange thing is, even now, when one tries to call my number, it still says "the call has been forwarded to a voicemail service that has not been initialized by the person you are calling". Strange, given that it's the exact same message that one would receive if I couldn't answer my phone, ON MY PREVIOUS SERVICE PROVIDER. And yes, it's the Koodo chip in my phone now, not the previous service provider's. I've checked my account online, as well. It says that I have been using airtime.
