@alexlabonte99 Your phone number is actually irrelevant in this context. It actually wouldn't make a difference even if you had a Vanouver or Whitehorse (or any other city) phone number. Are you actually in St. John's (or somewhere that it's local to call St. John's) when trying to make these outgoing calls? That's really all that matters.
I've noticed that everyone seems to be assuming that it's the "long distance may apply" message that is being heard. Yes, that message can be ignored and the call should go through afterwards, but that doesn't change the fact that this shouldn't be heard at all if you're in St. John's. St. John's to St. John's is always a local call, at any carrier.
So, while you can just simply ignore the "long distance may apply", message I'm going to ask something that no else has. Are you hearing that "long distance may apply" message, or are you hearing some other type of message similar that calls aren't included to the destination that you're calling/talk not included type message? If you're hearing the second type of message, calls will fail even if you stay on the line and wait in the hope that the call will complete.
As for the roaming question, there is no such thing as roaming while you are in Canada while using Public Mobile.
