Not all eSIMs are created equal—especially when it comes to unlimited data. Some promise “unlimited” only to slow you down after 3 GB a day. Others quietly cap your hotspot use or throttle your speeds without warning.
We’ve tested several eSIM providers —Holafly, Airalo, Saily, and Nomad—because we wanted to know which one actually works for tourists who use their phone a lot.
Whether you’re visiting for a week or a whole month, and whether you’re a heavy streamer or just hate running out of data, we’ve got the real story here. So you can skip the research rabbit hole—and enjoy your trip.

Up next: a deep dive into each provider—what we liked, what went wrong, and who it’s best for.
1. Holafly – Unlimited Data with the Easiest Setup
If you don’t want to stress about data limits—at all—then Holafly is your best bet*. We’ve used Holafly in Portugal, and had fast internet almost everywhere without needing to count gigabytes. It’s the one provider in our test that offers true unlimited data—no speed throttling, no usage caps.
Setup is smooth: you get a QR code by email or install it via their app, and it activates once you land. The app itself crashed once for us on an iPhone 15 Pro Max, but reinstalling fixed it. Support is quick and available via WhatsApp, which we found handy.
A small quirk: the German translation in the app was a bit awkward—but that probably won’t bother you if you’re reading this in English.
⚠️ What to keep in mind:
- Hotspot/tethering is limited—so if you plan to share data with a laptop or tablet, this could be restrictive
- More expensive than other options, but the peace of mind is worth it if you’re a heavy user

2. Airalo – The Easy Option with Daily Data Caps
Airalo is one of the best-known names in the eSIM world—and for good reason. We’ve used it in Germany and several other European countries and found it to be incredibly reliable. Setup is a breeze, the app is user-friendly, and the network worked great for maps, emails, and even video calls.
If you’re new to eSIMs, this is probably the easiest option to get started with. But there’s a catch: even their “unlimited” plan comes with a 3 GB/day full-speed limit, after which speeds drop to 1 Mbps. That’s okay for WhatsApp and Google Maps, but you’ll feel it if you’re trying to stream or upload big files.
Also worth noting: you have to create an account and log in before paying, and only after checkout can you apply any promo codes. Not our favorite UX setup, but manageable.
Another plus: you can recommend Airalo to friends and get “airmoney” credits for future plans. Nice if you travel often.
⚠️ What to keep in mind:
- Slower speeds after 3 GB/day
- No phone number (data-only)
- Slightly more expensive per GB than Nomad or Saily
🎯 Want a simple, reliable eSIM that works in Germany and beyond?
3. Saily – Solid Unlimited Option Backed by NordVPN
Saily is one of those eSIMs you might have seen all over social media—yes, they’re investing a lot in marketing. But here’s the good news: we’ve tested it ourselves, and it works smoothly. Setup was super easy, and the app lets you track data usage, find basic travel tips, and even see recommended tours (although you don’t see which platform you’re booking through—so, take those with a grain of salt).
What really builds trust is the fact that Saily is developed by the makers of NordVPN, a service we’ve used personally for years. That gives it extra reliability in our book.
Their “unlimited” data plan gives you 5 GB/day at full speed, then slows. For most travelers, that’s plenty, unless you plan to stream or upload videos non-stop. Plus, there’s an ad-blocker built in, which helps your data last longer.
Just be aware: you must sign in with a Google or Apple account. No email-only login available. If you don’t have one of those? Honestly, consider Airalo instead.
⚠️ What to keep in mind:
- 5 GB/day full speed, then throttled
- Google/Apple mail required
🎯 Want a reliable eSIM from a brand you know, with built-in ad-blocking?

4. Global YO
If you’re looking for the cheapest eSIM for Germany, your search will probably lead you to Global Yo*.
On paper, it looks unbeatable: unlimited data plans for a fraction of the price compared to others. But hold up—this one really requires a close read.
Global Yo offers two kinds of “unlimited” plans:
- Basic Unlimited: 1 GB/day at full speed, then throttled
- Premium Unlimited: 3 GB/day at full speed, then throttled
So yes, you can get unlimited data starting from $28 (which is insane value), but you’re limited to 1 GB per day on the lowest plan. After that, speeds slow significantly. If you want more flexibility, the premium tier gives you 3 GB/day before it slows down, with high-speed data resetting every 24 hours.
It’s also worth noting that reviews for Global Yo are mixed. While they have a pretty decent following on social media and keep running BOGO-style offers and discounts, some users mention inconsistent coverage or poor support.
That said, we like that they’re pushing the affordability boundary—just know what you’re signing up for.
⚠️ What to keep in mind:
- “Unlimited” = 1 or 3 GB/day, depending on your plan
- Mixed user reviews online
- Lowest cost, but reliability can vary by region
🎯 Want the cheapest possible unlimited data plan and are okay with daily speed limits?
Final Thoughts – Which Unlimited eSIM Is Best for Germany?
If you’re traveling to Germany and want to stay connected without relying on flaky airport WiFi or paying crazy roaming fees, an unlimited eSIM is a must. But “unlimited” doesn’t always mean what you think it does.
Here’s our honest advice based on real experience:
- Holafly* is the best choice for travelers who want true peace of mind. You pay more, but don’t have to think about data caps at all.
- Saily* hits the sweet spot between value and quality—especially with its 5 GB/day plan and built-in ad-blocking. Great for regular users who don’t want to mess around.
- Airalo* is perfect for tech-wary travelers who just want something that works. Setup is simple, and it’s beginner-friendly.
- Global Yo* is the budget wild card. You’ll pay the least, but you need to understand the daily speed limits and be okay with slower data after your daily cap.
