For a standard 5-7 day mission in Illinois, an eSIM Scout plan with 5 GB to 10 GB of mobile data is generally sufficient. This supports extensive navigation, moderate streaming, and regular social media updates. If your operational profile includes frequent high-resolution photo uploads, video conferencing, or prolonged tethering, consider upgrading to a 15 GB plan. Maintaining ample data ensures uninterrupted communication and mission effectiveness.
