How to switch from Samsung Galaxy S3 to S5 Active

I got my Samsung Galaxy S5 Active today and I put the SIM card that came with and it pops up saying :Attention (SIM not provisioned MM#2).  I bought the call from Amazon that is an AT&T phone. Can someone tell me what I need to do to so I can make calls, etc.?

if you have registered the phone number that the phone will have the phone should have came with instructions to activate, probably in an email, Here is a link to the att activation site https://www.wireless.att.com/activations/

Move the SIM card from your current phone to the new phone.
You can put the inactive sim in the old phone. If you backed up the old phone already, you will be ready to restore to your new, activated phone.

Take your phone to the nearest AT&T store and let the stuffs help you finish the installation, if you are not so sure what to do. Good luck!
