Help.
Last year we used walkie talkies without much success - too much interference and wouldn't work at parks with too many trees. I'm thinking about mobile phones.
Some of us have tri-band phones we use at home, and we must have any number of dis-used dual band phones. I don't think we could buy US pay as you talk sim cards for the dual band ones, but could we use them in our tri-band phones??
My DH and I are on different networks and tho we could both phone home and to the villa last time, we couldn't phone each other
Is there any other way of doing it? Cheaply??!
