Your connection leaves the network here. Services that judge your location by IP (streaming platforms, banking apps, search engines) may treat you as being in this country rather than the destination you are travelling to. The industry term for this is the IP exit country.

What people ask before buying
Does my phone support eSIM?
Most phones released since 2019 do — including iPhone XS and newer, Google Pixel 3 and newer, and recent Samsung Galaxy S and Z models. Your phone also needs to be carrier-unlocked. On iPhone you can check this in Settings → General → About → Carrier Lock, which should read “No SIM restrictions”. Dial *#06# and look for an EID number to confirm.
Can I share the connection with a laptop or tablet over hotspot?
Most travel eSIMs allow personal hotspot, but we will not promise it plan by plan: our suppliers do not give us a hotspot field, so we have no per-plan sharing limit and we will not turn data we do not have into a promise. Two things are certain. First, whatever you share over hotspot comes out of the same allowance as your phone, not a separate one. Second, laptops and tablets consume far more than phones, often several times as much for the same hour of video. So if the laptop is the main reason you are buying, choose a large or unlimited plan rather than a 1GB one. If hotspot is essential for this trip, contact us before you buy and we will check for your destination and get back to you.
Do speeds differ between eSIM sellers?
Connection quality mainly depends on the local mobile carrier, not the seller or upstream brand alone. Plans using the same local network with similar terms often offer a similar experience. Actual speeds still depend on signal, congestion, your device, roaming routes, speed caps and fair usage policies. Compare the supported carriers and high-speed allowance on the plan page; the same carrier does not guarantee identical speeds.
How do I get and install my eSIM after purchase?
Once payment is confirmed, your eSIM QR code is usually emailed to you within minutes. You can also find it anytime under “My Orders”, or look it up with your order number and email if you checked out as a guest. To install, display the QR code on another device and scan it, or enter the SM-DP+ address and activation code from the email manually.
When should I install and activate the plan?
Install the eSIM while you still have Wi-Fi, ideally before you fly. The validity period only starts counting once the eSIM connects to a network at your destination, so installing early costs you nothing.
What is the refund policy?
An eSIM whose QR code has not been scanned and installed can be refunded within 7 days of purchase, subject to approval by the upstream supplier. Once scanned and installed it cannot be refunded — at that moment the allocation is issued and taken by the carrier. If you hit signal or connection problems after scanning (force majeure aside), contact support: we pull the carrier's connection and usage records and decide on a refund after reviewing them. A few plans activate the moment payment completes and cannot be refunded at all; those are clearly marked on the product page. Top-ups also cannot be refunded once completed.
