What Exactly is an eSIM?
An eSIM (embedded SIM) is a digital SIM card that lives inside your smartphone's hardware. Unlike a traditional physical SIM, you don't insert a plastic chip. Instead, you scan a QR code or download a profile to activate your cellular plan. This allows you to have multiple profiles (e.g., your home number and a travel data plan) active simultaneously on the same device.
For travel specifically, this means you can purchase a data plan for your destination country before you even board the plane. Upon landing, you simply toggle the eSIM on, and you're connected. No more fumbling with SIM ejector tools or trying to communicate with a local vendor who doesn't speak your language.
The Saily Experience: A Deep Dive
I tested Saily's eSIM services during a whirlwind trip spanning the USA, Japan, and Germany. Here is the breakdown of my experience.
Setup Process: 9/10
The setup was remarkably straightforward. I purchased a regional Europe + USA plan on the Saily website using my laptop. Within 30 seconds, I received a QR code via email. I scanned it with my iPhone's camera, added the cellular plan, and was ready to go. The entire process took under 3 minutes. The only caveat is that you need a Wi-Fi connection to download the profile, which is standard across all eSIM providers.
Connectivity & Speed: 10/10
This is where Saily shines. In Tokyo, I experienced 5G speeds consistently. In rural Bavaria, where my friends with local SIMs had dropped calls, my Saily eSIM maintained a stable 4G LTE connection. They use top-tier local networks (like NTT Docomo in Japan and T-Mobile in the USA) rather than budget MVNOs, ensuring you get the best possible coverage in the region.
Battery Life: 8/10
There is a slight battery drain compared to a physical SIM, primarily because the phone is constantly scanning for the eSIM network. However, this was negligible—about 5-7% extra drain per day. It's a minor trade-off for the convenience.
Pros & Cons
✅ The Pros
- Instant Connectivity: Activate your plan before you leave home. No airport hunts.
- Keep Your Number: Your physical SIM stays active for WhatsApp, banking OTPs, and iMessage.
- Cost-Effective: Significantly cheaper than international roaming from major carriers.
- Dual SIM Functionality: Use your local number for calls and the eSIM for data simultaneously.
- Eco-Friendly: No plastic waste from physical SIM cards.
- Flexible Plans: Saily offers local, regional, and global plans that can be topped up easily.
❌ The Cons
- Initial Setup Requires Wi-Fi: You cannot install the eSIM profile without an internet connection.
- Device Compatibility: Older smartphones (pre-2019) do not support eSIM technology.
- Data Only: Most travel eSIM plans (including Saily) are data-only. You cannot make traditional voice calls unless you use VoIP (WhatsApp, FaceTime).
- Physical SIM Card Removal: Some users report issues if they swap phones often, as the eSIM profile is tied to one device until removed.
- No Physical Backup: If you lose your phone, you must contact support to re-download the profile on a new device.
Pricing Comparison: Saily vs. Traditional Roaming

Frequently Asked Questions (FAQ)
Is using an eSIM for travel safe?
Yes, it is absolutely safe. The eSIM uses the same encryption standards as physical SIM cards. You retain control over your data, and you can delete the profile remotely if your phone is stolen. It's actually safer than buying a physical SIM from a random kiosk, which could be a cloning risk.
Will an eSIM work on my phone?
Most smartphones from 2019 onwards support eSIM. This includes iPhone XS and newer (excluding SE 1st gen), Google Pixel 3 and newer, Samsung Galaxy S20 and newer, and most recent flagship models. Check your device settings (Cellular > Add Cellular Plan) to see if you have the option.
Can I still make phone calls with an eSIM?
Saily offers data-only plans. You cannot make traditional cellular voice calls. However, you can use WhatsApp, FaceTime, Skype, or Google Voice to make calls over the data connection. For most travelers, this is a non-issue.
What happens if I run out of data?
Saily allows you to top up your data plan directly from their app or website. You can purchase additional GBs in seconds, and it activates immediately. There is no need to buy a whole new package.
Can I use an eSIM for multiple countries?
Yes! Saily offers regional plans (e.g., Europe, Asia) and global plans. This means you can travel across multiple borders without needing to switch SIMs. The eSIM will automatically connect to local networks in each country.

Final Verdict: Should You Buy It?
In a word: Absolutely. Using an eSIM for travel has completely changed how I approach international trips. The fear of landing without a map, the anxiety of racking up a $200 roaming bill—these are things of the past. Saily, in particular, stands out for its user-friendly interface, transparent pricing, and the reliability of its network partners.
While the data-only limitation might deter some, the workaround (using VoIP apps) is so seamless that it hardly feels like a compromise. The convenience of having your travel data ready before you step off the plane is worth its weight in gold.
If you are planning a trip soon, I strongly recommend taking advantage of this exclusive 75% discount. It makes the already affordable plans an absolute steal. Don't wait until you're at the airport scrambling for a SIM card—get connected before you go.
