A SIM you download. No plastic, no tray to open: you scan a QR and your phone adds a new data line next to the one you already have.

If it's an iPhone XS or later, a Pixel 3 or later, a Galaxy S20 or later, or almost any flagship from the last few years, yes. It must not be carrier-locked. To be sure, dial *#06#: if an “EID” shows up, it supports eSIM.

Maps, WhatsApp and some browsing run about 1 GB a week. Add video or hotspot sharing and count on 5 GB for a week, 10 GB for two. You can always buy another eSIM if you run short.

If they're European, no: the Europe plan covers more than thirty countries on one eSIM. Same for the North America, South America, Asia and Global plans. For unrelated continents, one eSIM per destination usually works out better.

Yes, and you should. The days don't start counting until the eSIM first connects to a network at your destination, so you can buy and install it weeks ahead without spending anything.

No. Zas sells travel eSIMs: we resell data from local operators. We are not an airline and not a traditional mobile operator.

Before you leave, on Wi‑Fi. Downloading the profile needs a connection; activating it doesn't. If you wait until you land, you'll be without data exactly when you need it.

No. The profile downloads once and stays tied to that handset. If you're changing phones before the trip, write to us before installing it.

Yes. Sign in to your account with your email and you'll find the QR and codes for every order.

Use the manual install: the order page has the SM-DP+ address and activation code to type in by hand. If that fails too, write to us with your order number.

From the first time the eSIM connects to a network at your destination. Not from when you buy it, and not from when you install it.

When you land, switch on the Zas eSIM, set it as your data line and turn off data roaming on your physical SIM. Your usual number stays there for calls and SMS.

Yes. Anything that runs on data works the same. Your WhatsApp account stays tied to your usual number.

Not with the Zas eSIM: it's data only, with no number attached. Your usual SIM stays in the phone for calls and SMS. To talk, use WhatsApp calls or FaceTime.

Yes, on every plan. It comes out of the same allowance.

The eSIM stops carrying data. You buy another and install it there and then; there's nothing to wait for.

Yes. Price in euros, VAT included, no charges on arrival. What the button says is what gets charged.

Yes, a PDF with VAT broken out. Request it from your account or by replying to the order email.

Write to us with your order number. If the eSIM can't be installed, or gets no signal at your destination and hasn't been used, we refund you.

The eSIM is digital content delivered instantly, so paying waives the 14-day right of withdrawal. That doesn't change the line above: if the product fails, we answer for it.
