I really wonder what the difference is between numbers, I’m on telus and I don’t think they make any attempt to block them? And I’ve had my number for 20 years, with both bell and Rogers in the past. and made no effort to keep it secret. Thou I occasionally answer the calls when I’m bored and waste them time.
