What voltages do you see on the FONA's USB and 3.3V pins?

I need the readings from the FONA Feather to decide whether there's a hardware problem.

You don't need anything fancy. An inexpensive meter from an auto parts store or hardware store will be good enough.

It sounds like the onboard voltage regulator has failed.

When did you get the Feather?

We don't sell anything through Amazon, but some of our legitmate resellers do. Unfortunately there are also people who use our name without permission, so any replacements through Amazon have to go back through the vendor who actually sold you the board. If they're one of our resellers, they can contact our business team with a link to this page and the address support@adafruit.com.

All of our resellers on Amazon know we handle things that way, so let them know we've approved a replacement.
