Hi my phne freeze sim un av - Samsung SYNC SGH-A707 Cellular Phone

UN-freeze also called the PUK lock(Personal Unlocking Key). It's a security feature on most zte mobile devices that protects your SIM card data and unique for SIM card.
May I suggest that you contact your sim network provider as they are the only one who can provide you the PUK codes or UN-freeze code . for any network unlock code you feel free to reach
Unlock Your Cellphone Use Any Network in The World

you can get the subsidy code for your Motorola model mobile through this site www.mobile-unlocker.com/motorola-t720/rs2wp9 , it has the step by step instructions and simple methods for getting the subsidy code for your Motorola mobile from the network lock..........

This proccess will work on SOME samsung phones, I'm afraid I can not know for sure if it will work on your's:

1. Turn the phone off
2. Take out the sim card
3. Turn the phone back on
4. Enter *2767*2878#
5. The phone will turn off and then on.

Try finding the PIN and PUK code of this other SIM, every time you buy a new line the SIM comes with a personalized PIN and PUK that's usually in the same package the SIM came.

I KNOW, IT ALWAYS WILL FREEZE THERE IS NOTHING YOU CAN DO ABOUT IT, BUMMER I KNOW, TRY TO keep it ventalated, but most of all BUY SIMS 3, NO LOADING SCREENS, NO FREEZING ON CREATE A FAMILY, FRANKLY I SAY AMAZING.

Bring it to a cellphone repair shop. Then let them to replash your phne's firmware.
