FAQ
Plan type questions
Q1What is the difference between a fixed data plan and an unlimited plan?
A fixed data plan gives you a set amount of data (e.g., 5 GB) for a set period (e.g., 7 days). When the data runs out, the connection stops. An unlimited plan gives you uncapped data for a daily rate (e.g., $3.90/day). Some unlimited plans apply a fair-use speed reduction after a daily threshold.
Q2What is a regional eSIM plan?
A regional plan covers multiple countries on a single eSIM. Airalo's Eurolink covers 39 European countries; Asialink covers 16 Asian countries. You install it once and it works across every border in the region. Regional plans typically cost 30-60% less than buying separate per-country eSIMs.
Q3What is a global eSIM plan?
A global plan covers 100+ countries on one eSIM. Airalo's Discover Global covers 130 countries. Global plans are more expensive per GB than regional or per-country plans, but they eliminate the need to manage multiple eSIMs on long multi-region trips.
Q4Can I top up an eSIM plan if I run out of data?
Yes. Most providers offer top-up options through their app. Airalo allows you to add data to an existing eSIM without a new QR code. Holafly unlimited plans do not require top-ups since data is uncapped. Nomad and Saily also support in-app top-ups for active plans.
