Without an eSIM for Switzerland, you’re disconnected from the rest of the world. While you can always roam or buy a Swiss SIM, it makes little sense due to the price and inconvenience. However, the best eSIM for Switzerland is the polar opposite. Easy to set up, cheap, and with 5G data, it’s bar none, the best workaround.
A trusted eSIM for Switzerland allows a seamless internet connection without swapping out your original SIM card. Best of all, it activates as soon as you arrive. Out of the 20 we tested in Bern and Zurich, we selected 5 with the best coverage, reliable speeds, and low-cost Swiss eSIM plans in 2026.

Best eSIM for Switzerland: 5 Top Choices for Travelers
Travelers and digital nomads, you’re not alone. We often travel and test eSIMs, and know fairly well what it’s like to be stranded without internet data on foreign soil. We made this list to help you avoid common pitfalls and choose the best Swiss eSIM plan more easily. Let’s get down to business immediately.
1. Ubigi (Starting price: $6.5 for 3 GB of data for 30 days)
Pros
- Best value for money
- Smart IP feature
- Reliable coverage
- 24/7 support
- Affordable for long stays
Con
- No local phone number
Ubigi takes the #1 spot. It’s one of the most popular eSIM providers, offering one-off, monthly, and annual plans for Switzerland. Its cheapest plan is $6.5 for 3 GB of data, but our favorite is the unlimited plan for $24 for 7 days. Longer stays are pretty affordable, and the same plan for 30 days is $59.
Ubigi is characterized by extensive 4G and 5G coverage, with impressive speeds, connection stability, and overall reliability. In our tests, we enjoyed VoIP calls and played games without lag or buffering. Ubigi also encrypts your connection, so browsing is always secure. Another perk is unlimited data sharing.
We found this handy for team travels, which allowed us to rely on one eSIM for Switzerland. Ubigi’s setup is straightforward, with a QR code that you scan to make it work. As the best Swiss eSIM, it also features 24/7 live chat support. Some people complain about the lack of local phone numbers for calling and SMS.
However, that’s a nitpick considering Ubigi’s overall performance and unlimited allowance for 4G/5G data. Let’s not forget a 10% discount on your first purchase with the promo code GIZMODO, making this affordable eSIM even cheaper.
2. Saily (Starting price: $3.99 for 1 GB of data for 7 days)
Pros
- Cheap for short stays
- Bonus security features
- Fast connections
- Data usage tracking
Con
- Pricier for long stays
Saily starts at only $3.99 for 7 days, for 1 GB of data. It’s pretty affordable for short stays and offers incredible security features. You get an ad blocker and a virtual location, but if you get the Ultra plan for travelers, you get NordVPN, NordLocker, NordPass, and Incogni bundled for only $59.99 per month.
The best-value eSIM for Switzerland from Saily is the 10 GB option for 30 days for $22.99. However, unlimited data starts at $34.99 for 10 days. Saily is known for its speed and overall coverage, relying almost exclusively on 5G in this country. This makes calling, chatting, and even gaming buttery-smooth.
We love Saily’s 30-day activation period, which lets you pre-purchase the eSIM and activate it when you arrive. Unlimited data sharing is included, and users can track data consumption in Saily’s app on iOS and Android. Overall, Saily is a bit pricier than Ubigi, and like its rival, lacks local phone numbers; again, a nitpick.
3. Holafly (Starting price: $3.90 for unlimited data for a day)
Pros
- Unlimited data
- 5G speeds
- Automatic activation
- 24/7 support
Cons
- Data sharing limit (500 MB/day)
- No Swiss phone number
Holafly is an eSIM for Switzerland with unlimited data for $3.90 for one day. All plans include 4G and 5G coverage from Swisscom, SALT MOBILE, and Sunrise, and in our experience, this Swiss eSIM really packs a punch. Zero issues, zero connection losses; it’s tremendous. But, is Holafly good for long stays?
While the price goes down for longer stays, it’s still considerably high. For instance, 15 days of unlimited data is $50.90; Ubigi charges you $42, and it’s better. Holafly is still a trusted eSIM for Switzerland for its reliability and seamless activation. Your eSIM is automatically activated when you arrive.
We love Holafly’s 24/7 live chat support, and frankly, it’s the best we tested. Holafly supports many payment methods, including Apple Pay, Google Pay, and PayPal, so you can easily get it from anywhere in the world. Sadly, its data sharing is limited to 500 MB per day, a huge letdown compared to the others.
4. Airalo (Starting price: $4.00 for 1 GB of data for 3 days)
Pros
- Unlimited data sharing
- Flexible plans
- Effortless activation
Cons
- Slow customer support
- No calling or texting
One of the others is Airalo, one of the top eSIMs for France, Switzerland, and other countries in Europe. Airalo offers unlimited data sharing and cheap plans starting at $4 for 1 GB of data for 3 days. Even unlimited plans are affordable, at $10.5, $17, and $24 for 3, 5, and 7 days. You can go up to 30 days for $69.5.
Airalo is fast and reliable, but it relies only on 4G data, which isn’t as fast as 5G from Ubigi and other top picks. Still, Airalo performed well in our tests for streaming on Netflix, using VoIP apps, and casual browsing. Like the others, Airalo is easy to activate and offers an app that tracks data consumption.
We love Airalo’s flexible plans, which make it good for short- and long-term stays. Our only gripe is its underwhelming customer support, which isn’t as fast to respond as Holafly’s, one of the best support teams here. Airalo often offers phone number plans. However, its eSIM for Switzerland lacks them.
5. aloSIM (Starting price: $4.50 for 1 GB of data for 7 days)
Pros
- International phone number
- LTE & 5G data
- Regional/global plans
Cons
- Not the fastest
- Higher price
aloSIM is a widely adopted eSIM for Switzerland with an international phone number for calling and texting; a refreshment from the other picks. While you still have to top up your minutes and messages, it’s good to have it when needed. Other than that, aloSIM uses LTE and 5G data from Sunrise and SALT.
It’s reasonably fast, although slightly less than Ubigi and Saily. Its plans start at $4.50 for 7 days for 1 GB of data. Unlimited data is locked to 10 days and costs $35, while 20 GB of data for 30 days costs $36. aloSIM isn’t the cheapest pick, but it’s dependable and is ideal for dodging roaming charges in Switzerland.
Plus, it includes regional and global plans for a low price, both of which include a Swiss eSIM among many others. aloSIM has 24/7 support, apps for iOS and Android, and even a custom business eSIM for companies that frequently go on business trips. For this reason, it’s also a worthy eSIM for international travel.
How to Know if Your Phone Supports eSIMs?
The easiest way to see if your phone is compatible with an eSIM for Switzerland is to check on the provider’s website. Ubigi, Saily, and other options have a compatibility checker where you can type the model of your phone and see if it’s compatible. Below, you see the example of Saily and its compatibility checker:
At the time, we used the S25 FE, which Saily supported. Another method is to go to Settings on your phone and see if there’s an option to manually add an eSIM. Either way, even if the chosen eSIM for Switzerland doesn’t have a compatibility checker, you can reach out to its customer support and ask politely.
They’ll quickly tell if your phone is compatible. If it’s not, and you don’t plan to change to another one, you can always get a physical SIM card from the country you’re in, although it’s not the best course of action.
The Final Verdict
The best eSIM for Switzerland is Ubigi because it virtually has no downsides. Superb 4G and 5G coverage, low prices, and flexible plans; it’s a jack of all trades. Saily excels at security, and Holafly is a master of unlimited data. Airalo is a data-sharing machine, and aloSIM is the best pick for limitless data sharing.
All five were tested by our experts and proven to work reliably. The final choice ultimately boils down to your data needs and trip length, and above all, what you can afford. So, either snatch Ubigi at 10% off or explore other choices.
Frequently Asked Questions
What's the best cheap eSIM for Switzerland?
The best cheap eSIM for Switzerland is Ubigi, as an affordable pick overall. It's not the least expensive, but its packages have the best value for money. As for the cheapest pick, that's Holafly and its $3.90 price tag for unlimited data for a day. However, it's expensive for longer stays, in which case, Ubigi is more affordable.
How is eSIM better than a physical SIM?
In many ways, the main advantages are convenience, reliability, and practicality. A good eSIM is installed without swapping out your old SIM, and it works just as well as a physical SIM card in terms of reliability and speed. It's also practical because you don't need to carry it with you, and thus, you can't lose it.
Not to mention that an eSIM can be regional or global. For instance, there are eSIM plans for Asia, which cover more countries on a single plan. You can't buy a physical SIM card that works in multiple countries without roaming fees.
How much internet data does an eSIM offer?
The range goes from 1 GB to unlimited, depending on the plan. 1 GB is typically the cheapest option, but unlimited data is good if you plan a longer trip.
