Ok, i am needing more and more ,a walky talky type / phone, to communicate with others while im at work. I was told the walky talky is free, but the phone part costs . Whats the deal with these things? Who has a killer plan , with a sweet phone? I was thinking about the motorolla waterproof phone/walky talky,but i was wondering, how does this work? Who has the best deal? It will be used mostly for commercial /buisness use, Thanks guys,Jacob ........how much???
