Saily's New Unlimited Data Plans Change How Travelers Buy International Phone Service

Saily, a travel phone service app owned by the company behind NordVPN, launched unlimited data plans in May 2025. Until now, most travel phone plans sold you a set amount of data — like buying a gallon of milk instead of drinking as much as you want. This unlimited option changes that.

The announcement came on 7 May 2025 and puts Saily in a small but growing group of companies offering unlimited plans for international travel.

What Saily Actually Is

Think of Saily as a middleman between you and local phone networks around the world. When you travel, instead of buying a local SIM card in each country, Saily lets you download a digital SIM onto your phone — called an eSIM — and connect to local networks without touching any physical card.

Saily does not own the phone towers or network infrastructure. It negotiates deals with local carriers in each country and resells that connectivity through an app on your phone. If you already use NordVPN for privacy, Saily is marketed to you as a way to stay connected while traveling.

The travel phone market has existed for about five years now. Most plans worked the same way: you paid a fixed price for a set amount of data — 3 gigabytes, 5 gigabytes, 10 gigabytes. Saily's unlimited plans shift the conversation toward a flatter, simpler option — more like what you might be used to at home.

How the Unlimited Plans Work

Saily offers unlimited plans on a per-country or per-region basis. You can activate them in a few minutes through the Saily app on iPhone or Android.

Here is what "unlimited" actually means in this context: there is no hard cap — you will not hit a wall where your service cuts off. But there is an important catch. Unlimited international plans do not work like home broadband. Once you use more data than a certain threshold — which Saily and its local partner networks decide — your speed slows down. It does not shut off, but it throttles, meaning your videos load slower and your messages take longer to send.

This is a technical point that deserves attention. The threshold where throttling kicks in is decided by the companies involved, not by regulators, and the fine print matters if you plan to stream video, join video calls, or sync large files while abroad.

Why This Matters

For most travelers, the biggest change is simpler decision-making. Instead of guessing whether you need 3 gigabytes or 5 gigabytes before your trip, you buy unlimited and stop worrying about running out. That removes stress, especially for business travelers who just want to submit one expense instead of managing a data budget for each trip.

Saily is not the first to offer this. Two competitors — Holafly and Nomad — have already rolled out unlimited options on some destinations. But Saily has a head start: it is backed by NordVPN, a brand that millions of people already know and trust. That brand recognition could pull more customers from smaller competitors.

A Reality Check on "Unlimited"

The travel phone market sits in a gray zone. Regulators have started paying close attention to "unlimited" plans in home markets — in Europe, the UK, and the US — because companies sometimes advertise unlimited service but then slow it down after a small allowance. But travel plans like Saily's are not governed by those same rules. The throttling threshold is a business decision, not one set by regulators.

This pattern has played out before. When US phone carriers started offering unlimited home plans around 2017 to 2019, the headlines were exciting, but the fine print told a different story. Several carriers got criticized and had to be more transparent about when speeds would drop. The travel phone market is earlier in that story, and there is no regulatory requirement yet for companies to be clear about throttling thresholds. If you need fast, reliable speed for a video conference or large file transfer, read the terms carefully — casual web browsing will look very different from streaming video.

What This Means for You

For everyday travelers — people checking maps, texting, and browsing the web — an unlimited plan removes one source of decision fatigue. You pay a flat rate and stop thinking about data.

For power users — people who stream constantly, tether their laptop to their phone, or rely on sustained video calls — the real story depends on what speeds Saily actually delivers after the throttling threshold. That will become clearer over the next few months as more people use these plans and report their real-world experience.

Saily's move points to a broader shift in how travel phone service is sold. The industry is moving away from the old model of nickel-and-diming people per gigabyte, toward simpler plans, better app experience, and the brand names that people trust. That is a familiar pattern from every generation of consumer connectivity.
