My boyfriend got out of jail yesterday and hasn’t contact me yet?

My boyfriend was supposed to be released next Wednesday but they released him yesterday. I didn’t know this until I contacted his sister today because he hasn’t called me yesterday from jail and it wasn’t like him. This is the second day I haven’t heard from him. He’s been in jail for almost 7 months.. what should I do?
