i have misplaced my phone and it is on silent mode is there a way to make it ring?

If you have Find My iPhone activated, you can log into iCloud, select your device if it is online and click on play sound. It will play a sound no matter if mute is activated or not and you should be able to find it. Listen carefully.

icloud.com sign in- find my device -play a sound -see it on a map- use lost mode

Peace, Clyde
