Latest questions about "verification code"

My old phone got totally messed up like I can't even turn it on anymore. I was trying to log into my new phone on Snapchat, but it needs the verification code, and I can't see the code.

I changed my phone and SIM so when I try to log in to Snapchat it sends a (verification) code to the old sim. Problem is I don't have the old sim anymore with me.
