Really? Wow I'm really good at this.
For the record nothing would stop you even if you changed your number. You'd have to get a whole new phone and sync it to a whole other Google account IF I was being creepy.
100% honest I just took guesses as most people have androids, I own a J3 emerge which is the most common phone on the market right now and the Galaxy series is the most popular series of the Samsung line which most people have as well.
Just a little deductive reasoning and a few keen guesses based on what I know about phones.
You really think I'm that obsessed over you that I'd hack/remote access your phone? Wow Kitchen you need to get a life :3
Since I know you won't believe me I was seriously just fucking with you and I'll text you the Mrs number so you can ask her yourself she's been with me the whole time.
Give you a small heart attack and make your heart race love? You sweating? I fucking got you good with the NEET's worst nightmare. I also don't know your IMEI or anything like that. Just a simple mental trick and some good sound logic. Not that I couldn't get it but I wouldn't do that unless your phone was really hacked and you wanted your shit off it.
Still I got you good.
