Very weird. I am a Bell Canada customer (Bell Mobility), and have had a regular (not Smart) cell phone with them for the past 6 years. I have NEVER received a unsolicited sales call on my cell in that time. Two weeks ago I "upgraded" to an iPhone 5S, with the same cellular number but new data package, and so far I have received THREE unsolicited sales calls, all regarding free vacations/cruises (two from a Nova Scotia exchange, and the last one - an hour ago, from this number). What is Bell up to?
