If you purchased a plan without data (namely the USA Saver, USA Daily or USA Budget Plan) and now want to use data on your phone, you have two options:
1. You can purchase the USA Extreme Plan (for $89) by clicking here. Unfortunately it's not possible to add a data pack to the USA Saver, USA Daily or USA Budget Plan. Also please note that if you now buy the USA Extreme Plan you will lose/forfeit the original plan you purchased (it cannot be refunded).
2. You can stay on your existing plan and just use Wi-Fi data in your hotel and other places where it is available.
