Can someone help me with my iPhone?

[Fracture]

My mom and step-dad recently switched over to Sprint to save money, but my mom knows that I like my iPhone, and that I switched to Sprint, I couldnt keep it. So, her solution was to switch my phone to my dads plan.
Well, the people at AT&T were handicaps, and couldnt switch the number over, so my dad just got me a new Simcard and Number. Well, when I got home today the Simcard was in the mail.
I put the card in about an hour ago, and im having an issue connecting to AT&T. On the top right, where it usually says, "ATT and Your wifi connection", mine just says No Service.
Is there a way to fix this?

Move somewhere else in your house?
That works for me. There are signals around my house, even my garden.
If not then im out.

AT&T might not cover that area that you are in. You might also try contacting AT&T.

Reset your iPhone. Hold down the lock AND home button. It might help.
