I bought an unlocked iPhone and i was texting people through iMessage when I had wifi. Now I am getting messages through normal texts only. When I go to the "Send & Receive" option under message settings, my phone number is there but it is gray in color and I cannot select it. All the email addresses on the account can be selected but not my phone number. Can anyone help me?

On average.

I'm doing a science project and everybody in the class needs to make a periodic table of something. I am organizing mine by position horizontally and yearly salary vertically. So, I really do not need the highest paid position by average, I need the average of top four highest paid for each position. I'm sorry it is kind of confusing.
