1. A method comprising:
enforcing a first geofence having a radius with a first value for a device, wherein the device is connected to a cellular network;
based on receiving an alert triggered by the device crossing the first geofence, determining if a delay associated with generation and transmission of the alert satisfies first criteria for modification of the radius based on indications of location identified in the alert;
based on determining that the delay satisfies the first criteria, modifying the radius from the first value to a second value to create a second geofence; and
enforcing the second geofence for the device.
