In a world where mobility, flexibility, and digital security are paramount, eSIM technology has revolutionised how we stay connected. Whether you’re a jet-setting professional, a digital nomad, or a casual traveller, the Saily eSIM app offers an innovative and hassle-free way to access mobile data globally without the exorbitant fees and logistical headaches that come with traditional SIM cards.
Saily, developed by the cybersecurity experts behind NordVPN, is a cutting-edge eSIM platform designed for travellers, remote workers, and privacy-conscious users. Below, we explore the top 10 real-world use cases for Saily eSIMs, breaking down how this tech-forward service can simplify your life—no matter where you are in the world.
1. Seamless international travel
Use case: Frequent travellers often juggle multiple SIM cards to stay connected abroad.
Why Saily?
Travelling internationally comes with enough complications—queues at airport SIM kiosks, dealing with language barriers to buy local SIMs, or hunting for stable Wi-Fi. Saily eliminates these hassles by providing instant access to prepaid data plans across 150+ countries. Whether you’re flying to Europe, Asia, or the Americas, simply install the Saily app, choose your destination, and activate a data plan the moment you land.
What sets Saily apart is its region-specific bundles, such as “Europe 10GB for 30 days”, priced competitively with local providers—no roaming markup, no surprise charges. The app works on all major eSIM-compatible devices, including iPhones and Androids.
Best of all, Saily incorporates the digital security legacy of NordVPN, meaning your public Wi-Fi sessions are encrypted and private. Say goodbye to pocketing multiple SIM cards or losing your connectivity mid-transit—Saily has your travel needs covered from touchdown to takeoff.
2. Cost-effective business trips
Use case: Professionals need reliable, high-speed data for emails, video calls, and cloud apps.
Why Saily?
Business travellers require uninterrupted, high-speed internet for Zoom meetings, email communication, and cloud collaboration. Saily’s eSIM plans for professionals include unlimited data options in business hubs like the United States, Japan, Germany, and the United Kingdom.
Beyond just connectivity, the Saily app includes features tailored for corporate needs. Business travellers can track expenses in real-time and download itemised invoices, making reimbursement and budgeting easier. 24/7 customer support ensures any technical issue is addressed swiftly. Furthermore, Saily prioritises LTE/5G access in most locations, ensuring you remain connected whether you’re working from a hotel lounge, airport, or conference centre.
3. Remote work flexibility
Use case: Digital nomads require stable internet to work from cafes, co-working spaces, or rural areas.
Why Saily?
Digital nomads are constantly on the move—from Bali’s beaches to co-working spaces in Lisbon—and they demand a consistent, secure connection. Saily’s “Global 20GB” plan is purpose-built for this audience, offering coverage in over 50 countries with transparent, prepaid pricing. This ensures remote workers can maintain productivity without being tethered to local contracts or unreliable Wi-Fi.
Saily also allows seamless integration with NordVPN for secure access to corporate tools, email servers, and internal documents. Dual-network switching ensures you’re automatically connected to the best available signal, reducing the chances of losing connectivity in remote or rural locations. Whether you’re attending a virtual meeting from a Costa Rican café or uploading files in Chiang Mai, Saily makes it easy.
4. Avoiding exorbitant roaming fees
Use case: Traditional carriers charge steep fees for data usage outside home regions.
Why Saily?
International roaming charges from traditional telecom providers can be excessive, often catching users off guard with sky-high bills. Saily tackles this problem head-on by offering transparent, prepaid pricing with no hidden fees. For example, a 5GB data plan in the US via Saily costs a fraction of what major carriers like AT&T or Vodafone charge for roaming.
Saily users can easily switch between their home SIM and Saily’s eSIM through their device settings—no need to remove your physical SIM. This hybrid approach gives users full control over their data usage and spend, helping you stick to your travel budget without sacrificing connectivity.
5. Temporary local phone numbers
Use case: Short-term visits require local numbers for ride-hailing, deliveries, or reservations.
Why Saily?
Whether you’re ordering food through Uber Eats, booking a taxi, or confirming a restaurant reservation, having a local phone number can be a necessity during short stays. Select Saily plans offer temporary phone numbers valid for 7 to 30 days in over 30 countries.
These temporary numbers allow you to communicate efficiently without exposing your personal number to strangers or platforms. This is particularly useful for Airbnb hosts, short-term renters, or anyone managing local services while travelling. Cancelling the number is as simple as letting the plan expire—no paperwork, no long-term commitment.
6. Backup internet for emergencies
Use case: Primary network failures can disrupt critical tasks.
Why Saily?
Internet downtime can be catastrophic during important tasks—be it a live interview, exam, or business deal. Keeping a Saily eSIM loaded with a minimal data plan (e.g., 1GB for US$5) as a backup ensures that you’re always prepared.
Switching to your Saily connection can be done in seconds via your device settings, and the app’s low-balance alerts make sure you’re never caught off-guard. Having Saily as your secondary provider provides peace of mind, especially in areas where your main carrier might struggle with coverage.
7. Budget-friendly data plans
Use case: Users seek alternatives to overpriced carrier contracts.
Why Saily?
From students to budget travellers, affordability is often the primary concern. Saily delivers unbeatable value with regional and country-specific plans that undercut even the most competitive local telcos. For example, 10GB of data in Thailand via Saily costs around US$15, while local telecom providers charge upwards of US$30—with additional hidden fees.
There are no credit checks, no binding contracts, and absolutely no hidden charges. This makes Saily perfect for those on a tight budget or anyone looking to avoid the complexity and cost of conventional mobile plans.
8. Effortless device switching
Use case: Users with multiple devices (phones, tablets, hotspots) need shared data.
Why Saily?
Many users juggle between smartphones, tablets, and mobile hotspots. While eSIMs are generally device-specific, the Saily eSIM app makes it easy to manage multiple data plans in one account. Store various profiles, switch between them effortlessly, and avoid the hassle of physical SIM swapping.
This functionality is ideal for tech enthusiasts upgrading their phones, parents lending tablets to kids, or professionals sharing hotspots during team trips. With Saily, no SIM ejector tool is necessary—everything happens in-app, instantly.
9. Enhanced privacy and security
Use case: Public Wi-Fi and SIM swaps expose users to hacking risks.
Why Saily?
Using public Wi-Fi in cafes, airports, or hotels increases the risk of data theft. Saily’s encrypted app and built-in NordVPN integration offer enterprise-level security, ensuring your browsing, logins, and transactions remain private.
Unlike physical SIMs, eSIMs cannot be stolen or swapped, eliminating one of the most common techniques used by cybercriminals. For added anonymity, you can even use disposable numbers for online transactions or temporary registrations.
10. Multi-country itineraries
Use case: Backpackers or cruise travellers visiting several countries in one trip.
Why Saily?
For travellers crossing multiple borders—whether on a European rail journey or a Caribbean cruise—Saily’s “Global” and regional plans are game-changers. These multi-country data bundles (e.g., “ASEAN 15GB” or “EU 20GB”) offer seamless connectivity across borders at a single rate.
Instead of swapping SIMs every few days or hunting for new providers, you activate your Saily eSIM once and enjoy stable data across all included destinations. This means more time enjoying your trip and less time configuring devices.
