Dropped my iphone 5 by mistake and now the screen is cracked?

The screen is cracked and the phone its self is a little glitchy. Its a verizone phone that i think i have insure for. But i'm now under tmobile.so, does my insurance still count if i'm under a different network?

why not buy a new one

Since you switched to T-mobile, I highly doubt it.
