Sell me a phone

I' ve had this running through my head as I travel to clients and struggle with getting a good signal in the middle of farmland. With apologies to David Bowie:

Sell me a phone with buttons of silver.
Sell me a phone that's red and blue.
Sell me a phone that I can hear on,
Sell me a phone that you can hear too.

To the tune of an early Bowie song, Sell Me a Coat.  Get this tune caught in your head and enjoy.
