Like the $5 pass, <strong>an additional $10 charge triggers automatically once you hit the 1 GB limit.<\/strong><\/li>\n\n\n\n<li><strong>Note:<\/strong> Since this plan offers 80% less data for double the price, it\u2019s worth checking the My Optus app to see if you can switch to a &#8220;Choice Plus&#8221; plan before you fly.
