I just recently upgraded from the galaxy s5 to the galaxy s7 about a week ago, kept the same number as before and transferred all my apps/data from the old phone to new phone. Roughly a day ago I started to receive calls from random numbers, I usually don't answer numbers I don't know but after receiving a few within a day, I decided to answer. So when I answer these calls people ask who I am and say I have the wrong number. Now I haven't even called anybody from my phone for the past week but keep receiving more and more phone calls from random people saying I've been calling them. Anybody else have this issue or know what to do to fix it?
