As a general rule, mobile devices often sit behind firewalls and Network Address Translators (NATs) of the mobile network operator, for reasons of security and manageability. (One can occassionally find some exceptions though.) That can make it difficult for an external IP-based host or device to learn the IP address of a mobile device (or in general of any IP device that sits behind a NAT firewall), unless the mobile device has first initiated and maintains a connection to it.

This slideset might help to give a better understanding of some possible issues that can be involved: "Multi-user MIDP Game Design" (http://www.forum.nokia.com/ndsCookieBuilder?fileParamID=3302).
