Just started this last week, started using Koodo in September. A friend tried calling and the calls didn’t connect or went straight to voicemail. Hadn’t changed the settings and voicemail is disabled as per the instructions and set for max rings. Managed to arranged for call back - sat and watched the phone, they tried 3 times and it never rang and I didn't have a chance to answer it as it must have gone right to voicemail. This has happened with phones from other cell phones and from landlines. Its very important we have a phone for calls to the doctor as my husband has Parkinsons Disease and we have regular phone check ups scheduled.
