How does a flashing cell phone charm work?

by BeInspiredDesigns

I bought a cell phone charm that flashes when I turn on my cell phone and is supposed to sparkle when I get a call (I haven’t had time to test it yet, but I know it flashes when my cell phone comes on).

How does this work? I don’t see any sort of way to open the charm up to replace any sort of battery…will it eventually go terrible or do they generally last a long time?

Answer by Hugo
The charm detects the different radio waves that your phone emits. When you turn your phone on, your phone searches for the network and the charm picks up on that. Same with a call, your phone sends a signal to the network to receive the call. Your charm should last for about a year.
