You choose a daily high-speed data allowance (for example 1GB or 2GB per day, depending on availability). That data renews each calendar day of your trip.
When you use up the high-speed allowance for the day, you stay connected at a lower speed (often around 1 Mbps) until the next day — still unlimited, just not at full LTE/5G speed.
Pick the number of days you need below; the total price scales with trip length. By default we select one speed tier; use Change speed tier if you want more daily high-speed data.
