In brief, it is because internet connectivity on most cellular networks goes through single gateways and devices are effectively "tunnelling" to those gateways.

In brief, it is because internet connectivity on most cellular networks goes through single gateways and devices are effectively "tunnelling" to those gateways. As long as the tunnel stays up and the mobile device is still identifiable on the RAN then the IP address assigned from the internet gateway doesn't need to change.
