Saily discount code EDC10 applies a 10% discount to Saily travel eSIM plans, reducing the price of a data plan for your next trip. This guide explains what Saily is, how an eSIM differs from what you already have in your phone, and the limitations that are easy to miss when buying one.

Saily is the travel eSIM product from Nord Security, the company behind NordVPN and NordPass. It launched in 2023 and sells prepaid mobile data plans for travellers through a single app, covering a large number of countries and destinations — figures reported across review sites range from 150 to over 200 depending on how regions are counted.

The pitch is the Nord ecosystem's usual one: a single app, a clean installation process, and privacy-oriented features layered on top of the connection. The underlying service, as with every eSIM reseller, is capacity bought from local mobile network operators in each destination.

An eSIM is a SIM profile installed as software rather than as a physical card. Modern phones have a small embedded chip that can hold several profiles at once, so you can keep your existing home SIM active for calls and texts while a travel eSIM handles data.

That dual-profile capability is the real benefit. You are not swapping out your home number, losing incoming calls or fiddling with a tiny tray in an airport. You install a profile before you leave, activate it on landing, and your phone routes data through a local network at local rates rather than through your home carrier's roaming tariff.

The prerequisite is an eSIM-capable and carrier-unlocked handset. Most flagship phones from the last several years qualify, but a device locked to a carrier may refuse to install a third-party profile. Check this before you buy any eSIM plan, not after.

The pricing logic is consistent across the category: the wider the coverage, the higher the cost per gigabyte. Buying a global plan for a single-country trip is the most common way to overpay, and no discount code compensates for choosing the wrong plan type.

Saily's app handles the entire lifecycle — browsing plans, purchase, installation, monitoring usage and topping up. Auto top-up is available and can be set to add data when your balance falls to a low threshold, which is useful on longer trips where running out mid-journey is genuinely disruptive.

The Nord Security heritage shows in the security features layered onto the connection, including ad and tracker blocking. Whether that is a deciding factor depends on whether you already run a VPN or content blocker; if you do, the overlap is substantial.

Tethering is supported on fixed data plans, which is worth confirming for your specific plan because it is a common restriction elsewhere in the category. If you travel with a laptop or a second device, an eSIM that blocks hotspot use is significantly less valuable.

Saily is a data-only service. There is no phone number attached, so you cannot make or receive standard calls or SMS on it. In practice most travellers keep their home SIM active for those and use the eSIM purely for data, and messaging apps cover the rest — but if you are relying on SMS one-time passcodes from a bank, keep the home profile enabled.

Plan activation runs through the app rather than a web dashboard, which means you need the app installed and functioning. Reviewers note this as a mild inconvenience compared with providers that allow full management through a browser.

Unlimited plans are subject to fair usage. Speed throttling can apply after daily usage thresholds, which is standard across the eSIM industry but should temper expectations if you intend to tether heavily or stream. Unlimited in this market generally means unlimited at reduced speed after a threshold, not unlimited at full speed indefinitely.

Finally, an eSIM profile is typically tied to the device it was installed on. Moving it to a different handset mid-trip is usually not possible, so install it on the phone you are actually travelling with.

Saily is a solid choice in a crowded category, and the Nord Security backing is a reasonable proxy for the thing that actually matters with an eSIM reseller: that the company will still exist and still have working support when something goes wrong abroad.

The discount is small in absolute terms because travel eSIM plans are not expensive to begin with. Apply it, but spend your attention on picking the right plan type and a realistic data allowance — choosing a local plan over a global one for a single-country trip will save far more than 10% ever will. And check your handset is unlocked and eSIM-capable before you spend anything at all.
