Saily is a good travel eSIM for most international travelers, especially if you want prepaid data, broad destination coverage and an app-based setup. It is a weaker fit if you need a local phone number, the lowest price per gigabyte or dependable coverage in remote areas.
Saily advertises mobile data plans in 200+ destinations. Saily is owned by Nord Security, the company behind NordVPN.

Why Saily Is a Good eSIM
1. Saily Is Easy to Install and Use
Saily lets you buy and install an eSIM through its app before you travel. You usually do not need to scan a QR code or visit a phone shop. After you arrive, enable the Saily eSIM and data roaming for that line so it can connect to a local partner network.
Your phone must support eSIM technology and be carrier-unlocked. Saily also recommends disabling automatic mobile data switching so your phone does not use your primary carrier's roaming data by mistake.
2. Saily Works Well for Multi-Country Travel
Saily offers regional plans that cover several countries with one data package. You can also add plans for new destinations to the same Saily eSIM instead of installing a separate eSIM for every country.
That setup suits trips through Europe, Southeast Asia and multiple destinations in the Americas. Check the exact plan before buying, though. Saily advertises coverage in 200+ destinations overall, while its Global plan page lists 121 destinations.
3. Saily Includes Security Features
Saily plans include:
- Virtual location routing
- Ad blocking
- Web protection against known malicious sites and trackers
Saily says its virtual location feature does not replace a full VPN. If you need advanced VPN privacy, use a dedicated VPN service instead.
4. Saily Supports Hotspot Use
Saily provides instructions for using an iPhone or Android phone as a personal hotspot. This can connect a laptop or tablet while you travel, although tethering can use data quickly.
The Main Disadvantages of Saily
Standard Saily Plans Are Data-Only
A standard Saily eSIM does not include a regular mobile number, cellular voice calls or SMS. You can still use WhatsApp, Signal, FaceTime, Messenger and other internet-based services.
Saily also offers an optional US phone number add-on. It does not support MMS, premium-rate numbers or call forwarding, and some services may reject it for one-time passwords or two-factor authentication.
If you need bank verification texts, keep your primary SIM active. Turn off data roaming on that line to reduce the chance of extra charges.
Saily Is Not Always the Cheapest Option
Saily prices vary by destination, data allowance and validity period. On ****, the US site showed a 20 GB, 30-day US plan for $36.99. The Global plan page listed 1 GB for $8.99 and 20 GB for $66.99 with a longer validity period. Prices can change.
Independent eSIM price tracking found that Saily had one of the lowest entry prices but did not rank first for value per gigabyte across all tracked providers. Compare the same destination, data allowance and validity period before choosing a plan.
Coverage Depends on the Destination
Saily uses partner networks in each destination, so performance can differ between cities, rural areas and countries.
Saily may meet your needs for maps, messaging and social media in major tourist areas. A local SIM or carrier plan may suit you better if you need rural coverage, a local number or sustained high-speed data outside cities.
Unlimited Plans Have Fair-Use Conditions
Saily applies a fair-use policy to its unlimited plans. The word "unlimited" does not guarantee unrestricted speed or usage in every situation. Review the plan terms before buying if you expect to stream heavily, download large files or share data with several devices.
Who Should Buy Saily?
Saily makes sense if you:
- Want mobile data as soon as you land
- Prefer to buy a plan before leaving home
- Are visiting several countries
- Mainly need maps, email, messaging, ride-hailing and browsing
- Need hotspot access
- Prefer an app-based setup to buying a physical SIM
- Want ad blocking and web protection included with your plan
Who Should Choose a Different Option?
Consider a local SIM or another eSIM provider if you:
- Need a local number for calls or SMS
- Depend on coverage in rural or remote areas
- Want the lowest possible price per gigabyte
- Expect to stream heavily or share data often
- Have a carrier-locked phone or a phone without eSIM support
How to Decide Before Buying
- Check that your phone supports eSIM and is unlocked.
- Search Saily for every country you plan to visit.
- Compare the same data allowance and validity period with Airalo, Nomad and a local SIM.
- Choose a country plan for one destination, a regional plan for nearby countries or a Global plan for multi-continent travel.
- Install the eSIM before departure and turn off data roaming on your primary line.
Final Verdict
Saily is a sensible choice when you want a quick setup, prepaid data and one eSIM for several destinations. Compare other providers or a local SIM first if your priority is a local phone number, remote-area coverage or the lowest price per gigabyte.
