Rather than using the default Koodo voicemail number (which requires me to phone for messages, go through security, press numbers to repeat/delete etc.) I have a VoIP number that I set my phone to forward unanswered calls to. (The VoIP service forwards voicemails to my email address as sound files. Much more convenient.)
I just checked my first bill and see that Koodo charges me $0.50/minute for “Local aircharges” when someone leaves me a voicemail (in fact even when they don’t - as soon as I miss a call and it starts to forward it costs $0.50 even if they just hang up when I don’t answer). The number my voicemail forwards to is local; it’s in the same area code as my phone. My Koodo plan unlimited phone calls. Why am I being charged for a local call?
