The call lasted 19 seconds. They asked if I had ordered a phone from Bell, which was the case. As soon as I said yes, they said thank you and hanged up. No effort to engage or ask me any questions. It was quite surprising, but I think it was legit.
They say they're Bell, but the number comes up as confidential. They asked me to look for a suspicious SMS message that should have come up yesterday. I don't trust them.
