Who needs portability when you can have a good old-fashioned desk phone? This unusual phone lets you use your mobile phone SIM card to connect to wireless phone networks instead of landlines.
The CVFK-M14-US Business Phone looks like a regular desk phone, but is actually a dual-band (850Mhz/1900Mhz) GSM phone. That means it should work on all of the major US carrier’s digital networks. The phone works on either AC power or battery, so I suppose you could carry it around and whip it out of your purse to take a call if you want to look really silly.
Assuming you don’t want to invest in a landline, and don’t want to go with some sort of VOIP phone on your internet connection, this phone might work for you. Otherwise, I can’t see too much purpose if you already have a cell phone in your pocket.
If you can think of a good use for one of these, you can grab one over at Chinavasion for $67.91 (USD).
