Hi Cammy Fay,
Have you inserted the SIM card?
If you have, verify that it is inserted correctly. Here is an image taken from the Alcatel One Touch Pop Icon User Guide that shows how to do it.

If it is inserted correctly, try inserting a different, network compatible known working SIM card to check if the phone detects it OK and try your SIM card in another known working network compatible phone to prove that your SIM card is OK or not.
Basically swap the SIM cards between two same network phones and see what works where.
