eSIM or roaming: how to decide for your next trip

• It's data only. Andalu eSIMs are data only: each plan page lists data and days, with no phone number, calls or texts.
• Your number stays where it is. Your regular SIM keeps your number for calls and texts, at your home carrier's rates.
• You pay once. Each plan is a one-time payment, not a subscription. When the data is used up or the days end, mobile data on the eSIM stops, and nothing is charged again automatically.
• The days start when you arrive. For most plans, the days start counting the first time the eSIM connects to a network in a country the plan covers.

1. Estimate your data. Your phone already counts the data it uses, so look at a normal week in its settings.
2. Ask your carrier what data abroad costs on your plan in the countries you're visiting, and whether it's charged by the day or by what you use.
3. Compare a plan for the same days. Each destination page lists every plan with its data and days, and the price you see includes currency conversion and payment processing, so nothing is added at checkout.
4. Add what stays on roaming either way. Calls and texts to your regular number still go through your home carrier.

With an eSIM installed, choose it as the line for mobile data, and turn off data roaming on your home SIM while keeping it on for the eSIM. Then your home carrier doesn't charge you for data abroad. See using an eSIM alongside your regular SIM.

If what your carrier charges for your days abroad covers the data you need, roaming saves a setup step. An eSIM needs a phone that supports eSIM and is unlocked, and a few minutes to install it, ideally on Wi-Fi before you leave. Does my phone support eSIM? takes a minute to check.

Find your destination on the eSIM page, or start from a region: Europe, Asia, the Americas or the Middle East.
