Systems and methods are disclosed that determine whether a sender/recipient using an electronic messaging service (e.g., SMS messaging service or MMS messaging service) is located in a defined home zone. A communication network (100) in one embodiment includes a messaging system (102), such as an SMSC or an MMSC, and a home zone system (104). If the messaging system (102) receives an electronic message from a sender (121) to a recipient (122), then the home zone system (104) determines a location of the sender/recipient. The home zone system (104) also determines whether the sender/recipient is located in a home zone. If the home zone system (104) determines that the sender/recipient is located in a home zone, then the messaging system (102) forwards the electronic message to the recipient. If the home zone system (104) determines that the sender/recipient is not located in the home zone, then the messaging system (102) blocks the electronic message. |
