Methods, systems, and computing platforms for mobile data communication are disclosed. Processor(s) may be configured to electronically receive a plurality of user mobile interaction data and storing the user mobile interaction data in a computer readable database over a threshold period of interaction time for a mobile device. The processor(s) may be configured to electronically process the user mobile interaction data with a machine learning controller based on a set of machine learning training data including predefined user activity data so as to output at least one most probable time vector. The processor(s) may be configured to electronically output the at least one most probable time vector to a notification processing module.
