Could be conflicts on the serivce provider to the SIM. It will be good to have guidance from Samsung support with the SIM in question of the service providers which is not known.

Also was the Samsung locked when it was bought in the first place with a service provider? if so you must get the phone totally unlocked before any SIM can be accepted.
make sure the memory card is good with a scan, as a malware file can also lock up or hang the phone

Hello,

You can obtain the unlock code by calling the service provider its locked to, each phone has unique unlock code and we don't have any for you.

While on roaming my (B7722) cell frequently refreshes the sim & gets hanged.


The phone Freeze problem. Your phone has gotten hard-locked; it will not accept any unlock codes. This problem can only be caused by improper unlocking. Basically this happens if you or someone else has already entered 5 wrong unlock codes on your phone.
You can get the unfreeze code, NCK code and SPCK code from third party. After unfreeze your phone, you have to enter the NCK code to unlock and use it with any gsm network in the world. i will suggest the website Unlock-Zone.com which is doing good service .....you can approach this website
