eSIM data plans for United States

Fixed data plans: pick by how much data the trip needs

The six fixed data plans run from 1GB over 7 days up to 50GB over 30 days, all on AT&T. Validity is tied to the size, not the trip: the 1GB plan runs for 7 days, while every plan from 3GB upward runs for 30 days. A short visit that mainly needs maps and messaging fits the 1GB or 3GB size. Someone online for most of a month is comfortable choosing a size with headroom to cover the whole stay.

Unlimited plans: priced by the day, split across two carriers

The unlimited line is sold by the day rather than by data volume, under a fair use policy that reduces speed past a daily amount. Instead of choosing a size, the choice is how many days of the trip need coverage, from a single day at $6 up to 30 days at $126. These plans use AT&T and Verizon. Which of the two a phone attaches to is handled by the plan rather than chosen, and the lengths can be matched to the part of a longer stay that needs covering.

Matching the plan to the trip

For a trip under a week with light data use, the smallest fixed data plan and a few days of the unlimited line land close in price, so the choice comes down to whether a fixed cap is acceptable. The gap widens over longer stays: someone travelling for a month who prefers a day-based plan can weigh the 30-day unlimited plan against the 50GB fixed data plan, a high fixed cap against no cap at all. Trips with data needs that are hard to predict in advance, such as extended navigation or video calls spread across several weeks, are where the day-based unlimited plans remove the need to guess a gigabyte figure up front.
