I can't see why it cant work, how good is a different matter.

The system means having another sim card and pay as you go or monthly contract for the phone it uses so you have to work out the costs and remeber when pay as you go run out of air time!

You then need to decide where to site the phone to maximise signal strength and hope that wherever you use it your chosen network provides a good signal! You could of course use it abroad with roaming enabled on the phone, but again you would have the same signal problems.
