Try removing the Simcard and re-inserting it again.
Try another Simcard on the same phone and see what happens.
Could be your Simcard's been blocked.

Why is my phone showing me emergency call

* please check your simcard if its properly inserted, or try to change another sim. this is considered as "INSERT SIM".

* Also check the settings of your phone, might be set to airplane or offline mode as well as your APN settings.

I have inserted my simcard into the phone, but there is a lock symbol on the phone. It is not telling me how to unlock the keypad at all, so I am wondering if the phone itself needs to be unlocked? I...

Hi, Is there a lock switch on card? If so switch OFF to unlock. Also try removing batteries for 30minutes. Then try again. Be aware that most memory numbers could be erased. You may have to reprogram the numbers in again. Good luck.

Does changing mobile parts change display menu???

It sounds like he removed the at&t software, and "flashed" it with generic software. Should work fine for making and receiving calls, but without the at&t settings in your phone, internet and texting probably won't work.
In my opinion, it would have been better if the shop had explained what they planned to do before they did it so you would have a better understanding of what was going on. Hope this helps you.
