FAQ
Travel eSIM basics
What is an eSIM?
An eSIM is a digital SIM embedded in your phone. Instead of inserting a physical card, you scan a QR code or tap a link to activate a data plan. Most phones made after 2019 support eSIM.
How do you track prices?
We pull plan data from 5 major eSIM providers weekly: HelloRoam, Airalo, Holafly, Saily, and Nomad. We normalize all prices to USD and calculate cost-per-GB. The cheapest plan for each country floats to the top.
Why does one provider win in so many countries?
A provider's pricing depends on its carrier agreements, margins, and target markets. Some providers negotiate lower wholesale rates in specific regions and pass those savings on. Rankings update every week, so the leader can shift as providers adjust their plans.
Can I use an eSIM with my existing phone number?
Yes. An eSIM adds a second line for data only. Your existing phone number, calls, and texts continue working on your primary SIM. You just switch data to the eSIM while traveling.
How often are prices updated?
We re-check all providers every week. Price drops are reflected within 7 days. The "30d" column in each table shows whether the price went down, up, or stayed the same versus last month.
