The dial tone was invented as a signal to inform the user that the system was listening and ready to accept your number. It serves no other purpose.
Your mobile phone accepts your number independent of the telecommunication system. When you press "Call," your phone negotiates with the network on its own. This is similar to the mobile phone waiting for a dial tone. It's just not YOU waiting for the acknowledgment that the system is ready.

A dial tone is simply meant to signal you that you have a clear line to dial out on. just not necessary for cell phones.

Cell phones don't have a dial tone because they're more like radios than land-line phones attached to a network.

Because on cell phones instead of just having an open line yo ucna pick up and talk on, with cell phones (since they go digital instead of analog) when you dial a number and press send your cell phones sends a request to your provider to open up a circuit. A land line always has that circuit on. So you dialed, it open up a circuit to the number you called and then the phone starts sending and receving that data for your call. Basically the circuit is on demand (because of the limited resources of wireless telephony) instead of always on.
