A phone message

So, on Monday, I was talking to someone on the phone when my phone cut out. I was going to call them back when I got a text. I figure it was him trying a different way to get a hold of me. I read my text, and this is what it says:

"This is your really old phone speaking. You should get rid of me and treat yourself to some new hotness. I've served you well and need to be retired."

The number has a Phoenix area code, but it's not a number that I recognize. I'm thoroughly weirded out by this. Maybe I do need to get a new phone. Anybody wanna donate to the Buy J-Ra A New Phone Foundation, or the BJNPF?
