Should I change my number, after 1 day of having it?

I got a brand new phone number yesterday, and while I was texting my boyfriend I was accidentally texting someone that has 1 digit different than his number. The text had a comic of someone owning a Hummer vehicle. I just bought an iPhone and was testing out the Siri feature to send him a text regarding the comic. I told Siri, "He's a Joke." and Siri heard, "He's a jew." and that was what was sent. The receiving person told her husband and I started getting multiple calls from a blocked number and unblocked number, I finally answered and it was a man asking why I had sent this. I explained the situation twice to him. I was apologetic, never text or called back, and now I'm getting threatening voice messages and texts saying that, "I had better come clean or he is calling the police." My boyfriend says I should change my number, but it was an honest mistake!

Just change the number.

You can change your number. It's Breyer I you do
