What is Saily eSIM?
Saily is an eSIM service developed by Nord Security (the team behind NordVPN).
An eSIM (embedded SIM) is a digital SIM card built into your phone, meaning no physical SIM card is required.
Best for:
- International travel
- Business trips
- Short-term stays abroad
- People who don’t want to swap SIM cards
- Users who need to keep their original number active
Why I Recommend Saily (Real Japan Test)
1. Easy Setup (Beginner-Friendly)
From downloading the app to installation takes about 5–10 minutes.
No SIM ejector tool needed
No swapping physical cards
No risk of losing your SIM
2. Real-Time Data Tracking
The Saily app shows:
- Data usage
- Remaining data
- Expiration date
This helps you stay in control and avoid running out of data unexpectedly while traveling.
3. Japan 5-Day Test: Is 3GB Enough?
During my 5-day trip in Japan, I used:
- Google Maps navigation
- Searching restaurants and attractions
- LINE messaging
- ChatGPT for translation and trip planning
- Occasional photo uploads
If you avoid heavy video streaming and excessive scrolling,
3GB can be enough.
If you plan to stream videos or share hotspot with multiple devices, consider a higher plan.
4. Smooth ChatGPT Usage
Tested in major cities in Japan:
- Planning itineraries
- Translating menus
- Navigating transportation
- Checking opening hours
The connection was stable with no noticeable delays.
5. Keep Your Original Number
You can:
- Keep your home SIM active
- Receive OTP verification codes
- Use Saily for data at the same time
This is especially useful for banking apps and secure logins.
6. Hotspot Sharing Supported
You can share your connection with:
- Laptop
- Travel companions
- Tablets or other devices
