Best Unlimited Data eSIM for Italy in 2026: Why I use Sim Local
By Tom, an avid adventure traveler from The Netherlands continuously traveling the world since 2012, living a full time nomadic life.
Looking for the best unlimited data eSIM for Italy? In this guide I compare the most popular unlimited eSIM plans available for travelers visiting Italy in 2026.
Before we start, there is something important you should know: most eSIMs that advertise "unlimited data" are not truly unlimited. In reality almost every provider applies a fair usage policy (FUP), meaning you can only use a certain amount of high-speed data per day before your connection is heavily throttled.
I have been reviewing international SIM cards and travel eSIMs since 2016 and during that time I have tested mobile data solutions in more than 170 countries. From my experience, the term "unlimited" is often more of a marketing promise than the real experience travelers expect.
Imagine being on a long 12 hour train or bus ride through Italy and spending the first few hours streaming videos or scrolling Instagram. If your "unlimited" eSIM only allows a few gigabytes of high-speed data per day, your connection may suddenly slow down to unusable speeds for the rest of the trip. That is exactly the situation many travelers run into.
That is why in this comparison I focus on the real daily data limits, fair usage policies, pricing and overall value of each provider so you can choose the best unlimited eSIM for Italy without unpleasant surprises.

Quick Recommendation – Best Unlimited Data eSIM for Italy 2026
🥇 Best unlimited eSIM overall:Sim Local – highest fair usage limit with around 10 GB/day of high-speed data, which is significantly more than most competitors.
💰 Best budget unlimited eSIM: Saily – competitive pricing and 5 GB/day high-speed data with multiple plan durations from 5 to 30 days.
📉 Cheap alternative: Maya Mobile – affordable plans with 3 GB/day high-speed data, but lower limits than Saily or Sim Local.
⚠️ Less recommended for heavy data users: aloSIM only includes about 1.5 GB/day of high-speed data and Holafly does not clearly disclose its fair usage limits.
🌍 Traveling beyond Italy? Airalo can be useful for regional plans. See my comparison of the best eSIM cards for Europe.
📊 Don't need unlimited data? Many travelers are actually better off with a large fixed data bundle instead of a throttled unlimited plan. Compare the options in my guide to the best eSIMs for Italy.
Comparison of the Best Unlimited Data eSIMs for Italy in 2026
The table below compares the most popular unlimited data eSIM plans for Italy based on their real daily high-speed data limits, pricing and overall value for travelers. As explained earlier, most providers advertise "unlimited data", but almost all apply a daily fair usage policy (FUP) after which speeds are reduced.
That is twice as much as Saily, more than three times as much as Airalo and Maya Mobile, and much more transparent than Holafly, which does not clearly disclose its fair usage policy.
On top of that, Sim Local gives travelers access to all major Italian mobile networks: TIM, Vodafone, WINDTRE and Iliad. This makes it a strong option for reliable coverage in cities, rural areas and mountain regions.
With prices starting from around $29 USD, Sim Local offers the best combination of high-speed data, network coverage and overall value for travelers who want an unlimited eSIM for Italy.
On top of that, you can claim a 15% discount on all Sim Local eSIMs with the code "TRAVELTOMTOM" at checkout, not only for Italy but also for Europe, the USA, Japan and many other destinations.
If you are looking for a cheaper unlimited eSIM, then Saily is a good alternative with about 5 GB/day of high-speed data and multiple plan durations between 5 and 30 days.
Travelers who want a cheap unlimited eSIM can consider Maya Mobile, but the fair usage limit is only about 3 GB/day. Providers like Holafly advertise unlimited data but do not clearly disclose their fair usage limits, which makes it harder to evaluate their real performance.
What Does “Unlimited Data” Actually Mean for eSIMs?
When you see an unlimited data eSIM for Italy, it rarely means truly unlimited high-speed internet. Almost all providers apply a fair usage policy (FUP), which means you can keep using data, but only a limited amount is available at full speed every day.
What Is a Daily Fair Usage Policy?
A daily FUP is the amount of high-speed data you can use before your connection is throttled. After exceeding that limit, your speed is usually reduced to around 1 Mbps or even 512 Kbps. Even if a plan is marketed as “unlimited”, a low daily high-speed cap can completely change the real-life experience.
Why Low Daily Limits Are Frustrating
Once you reach the daily high-speed limit, messaging apps will still work, but streaming video, uploading photos, using hotspot data or browsing heavy apps like Instagram, TikTok or YouTube can become frustratingly slow.
That is especially annoying during long travel days. Imagine being on a 12 hour train or bus ride through Italy and spending the first few hours streaming videos or scrolling social media. If your unlimited eSIM only includes 1.5 GB to 3 GB of high-speed data per day, you could hit that limit halfway through the journey and then be stuck with a slow connection for the rest of the ride.
Many travelers underestimate how much data normal smartphone use consumes. Activities like watching videos, navigating with Google Maps, uploading stories, browsing social media or tethering your laptop can easily use several gigabytes per day. That is why I always recommend looking at the daily high-speed data allowance instead of the word “unlimited”.
Why Sim Local Stands Out
In this comparison, the Sim Local unlimited eSIM stands out because it offers around 10 GB of high-speed data per day, which is significantly higher than most competitors. That is more than enough for:
Streaming videos on YouTube or Netflix in SD/HD
Heavy social media usage like Instagram, TikTok and Facebook
Using your phone as a hotspot for a laptop or tablet
Video calls, cloud syncing and larger uploads
For most travelers this feels much closer to a truly unlimited high-speed eSIM experience than the plans that only allow 1.5 GB to 3 GB per day.
Best Network Coverage in Italy
Another advantage is coverage. Sim Local uses all four major mobile networks in Italy: TIM, Vodafone, WINDTRE and Iliad. That means stronger coverage across cities, rural areas and mountainous regions, with fewer dropped connections and more stable speeds.
1. Saily – Best Budget Unlimited Data eSIM for Italy
Pros:
Generous 5 GB/day high-speed data fair usage policy.
Multiple plan durations available from 5 to 30 days.
Competitive pricing compared to many unlimited eSIM providers.
Good overall value for travelers.
Cons:
Daily high-speed limit is half of what Sim Local offers.
Network partners in Italy are not clearly disclosed.
Data speed is reduced to 1 Mbps after the daily limit is reached.
The Saily unlimited eSIM for Italy is one of the best budget unlimited data options available. With around 5 GB of high-speed data per day, it offers a higher daily limit than many competing “unlimited” plans.
While it cannot compete with the 10 GB/day allowance of Sim Local, Saily remains a strong alternative thanks to its flexible plan durations and competitive pricing.
Overall, Saily ranks as the best budget unlimited eSIM for Italy in this comparison.
2. Airalo – Best Unlimited eSIM for Multi-Country Europe Travel
Pros:
Unlimited data plans are valid across all of Europe.
Transparent fair usage policy with about 3 GB/day high-speed data.
Hotspot/tethering supported.
Competitive pricing for regional travel.
Strong global brand presence.
Cons:
Daily high-speed limit of 3 GB is relatively low.
Connection speeds are throttled significantly (1 Mbps) after the daily limit.
Less suitable for heavy data users.
The Airalo unlimited eSIM can be useful for travelers visiting several countries in Europe. However, the daily limit of around 3 GB makes it less attractive for heavy data users traveling only in Italy.
If your trip includes several destinations across Europe, you may want to compare regional plans in my guide to the best eSIM cards for Europe.
3. Holafly – Popular Unlimited eSIM but Fair Usage Policy Not Disclosed
Pros:
Highly flexible plans with durations from 1 to 90 days.
Strong brand recognition in the travel eSIM market.
Simple pricing model with unlimited data advertised.
Cons:
The daily fair usage policy is not clearly disclosed.
Hotspot usage limited to about 500 MB per day.
Performance may drop significantly after the hidden daily limit is reached.
Holafly is one of the most well-known providers offering unlimited data eSIMs for Italy. However, the company does not clearly communicate its fair usage limits.
Because of this lack of transparency it is difficult to compare Holafly directly with other unlimited eSIM providers that clearly disclose their daily high-speed limits.
4. Maya Mobile – Cheap Unlimited eSIM with Low Daily Limit
Pros:
Affordable pricing starting around ~$20 for 10 days.
Plan durations up to 180 days.
Hotspot/tethering supported.
Cons:
Daily fair usage limit of around 3 GB.
Reduced speeds after the daily limit is reached.
Less suitable for heavy data users.
The Maya Mobile unlimited eSIM for Italy is a cheaper alternative for travelers staying longer in the country.
However, the daily high-speed limit of around 3 GB is noticeably lower than competitors like Saily and Sim Local.
If you plan to stay in Italy longer, you may also want to compare local prepaid SIM card options in my guide on the best prepaid SIM cards for Italy.
5. aloSIM – Cheap Unlimited eSIM but Very Low High-Speed Data Limit
Pros:
Affordable unlimited data plan around $35 for 15 days.
Hotspot supported.
Works on major Italian networks.
Cons:
Very low high-speed limit of only 1.5 GB/day.
Speed drops to around 512 kbps after the daily cap.
Heavy data users will hit the limit quickly.
Although aloSIM advertises unlimited data, the 1.5 GB daily high-speed allowance is one of the lowest among the providers in this comparison.
For travelers who rely heavily on mobile data, this limit can quickly become frustrating during longer travel days.
Buying a SIM Card at Italian Airports
Not sure if an unlimited eSIM is right for you? Another option is buying a local prepaid SIM card after landing in Italy. Instead of installing an eSIM beforehand, you can also get prepaid SIM cards at several major airports.
Just keep in mind that airport SIM cards in Italy are usually much more expensive than installing an eSIM before your trip or buying a prepaid SIM card later in the city.
Is an Unlimited Data eSIM Worth It for Italy?
For most travelers, an unlimited data eSIM for Italy can be very convenient because it removes the stress of constantly checking your data usage while traveling. However, it is important to understand that most “unlimited” eSIM plans still apply a daily fair usage policy.
If you mainly use Google Maps, messaging apps, social media and occasional video streaming, an unlimited plan with a reasonable daily high-speed allowance can work very well.
From my experience reviewing international SIM cards and travel eSIMs since 2016, the word "unlimited" in the travel eSIM industry is often more of a marketing term than a real technical description. Many providers advertise unlimited data but only allow a small amount of high-speed data per day.
This becomes especially frustrating during long travel days. Imagine being on a 10-hour train ride across Italy and after a few hours your connection slows down because you reached the daily limit. That is why I always recommend focusing on the daily high-speed data allowance instead of the word unlimited.
In general, plans with at least 5 GB or more of high-speed data per day offer a much better experience. In this comparison, the Sim Local unlimited eSIM stands out with around 10 GB/day, making it one of the most comfortable options for travelers visiting Italy.
Final Verdict: Best Unlimited Data eSIM for Italy
Choosing the best unlimited data eSIM for Italy mostly comes down to one key factor: the daily high-speed data limit. Almost every provider advertises unlimited data, but the real experience depends on how much data you can actually use before speeds are reduced.
In this comparison, the Sim Local unlimited data eSIM clearly stands out because it offers around 10 GB of high-speed data per day. That is significantly higher than most competitors and makes it the closest option to a truly unlimited travel eSIM for Italy.
If you are looking for a cheaper unlimited eSIM, then Saily is a strong alternative with around 5 GB/day of high-speed data and flexible plans between 5 and 30 days.
Travelers visiting multiple countries may prefer a regional plan. In that case, it may be worth comparing options in my guide to the best eSIM cards for Europe.
And if your phone is not eSIM compatible or you simply prefer a physical SIM card, you can also compare local options in my guide on buying a prepaid SIM card in Italy.
As someone who has been reviewing international SIM cards and travel eSIMs since 2016 and testing mobile networks in more than 170 countries, my advice is simple: always check the daily fair usage policy before buying an unlimited data plan.
