An architecture can facilitate and/or transmit reminders based upon device presence techniques in connection with a wireless communications network. For example, when certain mobile devices register with a particular network entity (e.g., a femtocell) that services a particular target location (e.g., place of residence), then such registration can be leveraged to indicate presence at the target location. Accordingly, reminders can be configured by custodian devices and delivered to subservient devices if certain predetermined conditions or criteria are satisfied in connection with the presence information.
