Best eSIM Providers Compared (2026): Which Provider to Choose for Travel? (Airalo vs Holafly vs simpleSIM)
Why Compare eSIM Providers Before Traveling?
The travel eSIM market has exploded in recent years. Dozens of providers now offer plans for international travelers, but not all are created equal. Between advertised prices, hidden fair use policies, tethering restrictions, and the near-total lack of calls and SMS, it has become essential to compare offers before buying.
This comparison analyzes the 3 main international eSIM providers: Airalo, Holafly, and simpleSIM, based on concrete criteria: actual prices by destination, network coverage, terms transparency, and included features. We have also included an overview of other providers such as Nomad eSIM, Alosim, and Maya Mobile.

Key Criteria for Choosing an eSIM Provider
Before diving into our comparison, it is important to know which criteria truly matter when traveling. Not all eSIMs are created equal.
Data Allowances & True Unlimited
Most providers offer either fixed data plans (e.g., 3 GB, 5 GB) or “unlimited” plans.
Hidden Speed Throttling (Speed Caps)
Here is the industry’s well-kept secret. Most “unlimited” plans actually come with a Fair Usage Policy (FUP). Once a certain high-speed data threshold is reached within a day, your speed is severely throttled, often rendering the connection unusable for the rest of the day. Honest providers clearly state this limit upfront (e.g., 1 GB/day before throttling).
Hotspot & Tethering
Can you share your connection with your laptop, tablet, or travel companions? Some providers completely block hotspot capabilities on their unlimited plans.
Voice & SMS
Data is great, but what if you need to call a hotel, text an Airbnb host, or contact your bank? 90% of travel eSIMs are strictly data-only.

Detailed Breakdown of eSIM Providers
simpleSIM : The Best Value for Discerning Travelers
While most providers lock you into either rigid data caps or “unlimited” plans with hidden restrictions, simpleSIM offers optimal flexibility with tailored plan types suited to every need.
✅ The most complete catalog on the market: simpleSIM is one of the rare providers offering both prepaid gigabyte packages and unlimited plans. You choose the exact formula matching your trip duration and usage intensity.
✅ 100% transparent fair use: Like all telecom operators worldwide, unlimited plans apply a Fair Usage Policy to preserve network integrity. The difference? simpleSIM clearly states the limits upfront (typically 1 or 2 GB of high-speed data per day before speed reduction), with no unpleasant surprises.
✅ Real calls and SMS included: This is where simpleSIM truly stands out. While 90% of travel eSIMs are data-only, simpleSIM offers European plans with unlimited calls and SMS.

Airalo : The Pioneer for Budget Travelers
Airalo is one of the most recognized names in travel eSIMs, offering coverage in over 200 countries and very competitive entry-level pricing.
Pros:
- Its pay-as-you-go model is straightforward: you purchase the exact data volume you need (1 GB, 3 GB, 5 GB, etc.).
- For a short weekend trip with usage limited to WhatsApp and Google Maps, Airalo is often the cheapest option.
- The mobile app is intuitive and well-designed.
Cons:
- Costs add up very quickly once you stream media (photos, videos, Instagram stories), use frequent GPS navigation, or share your connection.
- No phone number, no calls, no SMS: Plans are strictly data-only. If you need to make an emergency call or receive a bank verification SMS, this is not supported with Airalo.
- Per-gigabyte pricing for popular destinations can exceed the cost of an unlimited plan from simpleSIM if you use more than 3-4 GB.
Holafly : The “Unlimited” Option with Caveats
Holafly built its reputation on the promise of unlimited data for specific trip durations (5 days, 10 days, 15 days, etc.).
Pros:
- Peace of mind: you do not need to constantly monitor your data consumption.
- A simple interface with helpful multilingual customer support.
Cons:
- “Unlimited” has its limits: The Fair Usage Policy (FUP) is often vague at the time of purchase. Once a daily high-speed threshold is exceeded, your connection is throttled down to speeds that make browsing virtually impossible.
- Tethering is blocked on most plans: you cannot share your connection with your laptop, tablet, or family members.
- No voice or SMS (except incoming SMS reception in select destinations).
- Prices for long-haul destinations are often significantly higher than competitors.
Other Travel eSIM Providers Worth Knowing
The travel eSIM ecosystem includes other providers worth noting:
Nomad eSIM offers prepaid plans in over 150 countries with an intuitive interface. Pricing is competitive on small data allowances, but plans remain strictly data-only with no voice or SMS. Unlimited packages are somewhat rigid and do not let you select your exact trip duration: durations are locked to 3, 5, 7, or 10 days. If you travel for 8 days, you have to pay for 10.
Alosim (formerly Aloesim) delivers an experience similar to Airalo with per-GB prepaid plans. Rates are slightly lower in select countries, though network coverage is somewhat less extensive. Just like Nomad, there are no packages with calls and SMS, and unlimited plans are rigid without flexible durations (fixed to 3, 5, 7, or 10 days. If you travel for 20 days, you pay for 30).
Maya Mobile offers unlimited plans at attractive rates. However, like Nomad, the packages are rigid and poorly tailored for moderate users. If you travel for 15 days, you end up paying for a full 30 days of unlimited data!
Please note: None of these alternative providers offer plans with calls and SMS included. This is a unique feature that only simpleSIM delivers in the travel eSIM market.
Price Comparison by Popular Destination

Frequently Asked Questions About Travel eSIM Providers
The best eSIM provider depends on your needs. For light data use and a tight budget, Airalo is suitable. For unlimited data without requiring hotspot tethering, Holafly may suffice. For the best combination of flexibility, transparency, and features (including calls and SMS), simpleSIM is the most complete choice in 2026 with coverage across more than 200 countries.
Airalo offers prepaid per-GB plans (ideal for low budgets), while Holafly provides daily unlimited data. However, neither provider includes calls or SMS, and Holafly blocks tethering. If these features matter to you, simpleSIM is a superior alternative combining the best of both worlds.
It depends on the provider. Airalo allows tethering. Holafly blocks hotspot capabilities on most of its unlimited plans. simpleSIM allows tethering on all plans without restrictions. This is often overlooked when selecting an eSIM, yet crucial if traveling with a laptop or with family.
The vast majority of travel eSIMs (Airalo, Holafly, Nomad, etc.) are data-only. simpleSIM is one of the rare providers offering plans with calls and SMS included: unlimited calls and SMS in Europe, and 15 minutes of calls + 50 SMS worldwide through the Holiday World plan.
No. All “unlimited” plans apply a Fair Usage Policy (FUP). Once a daily high-speed data allowance is consumed (typically 1 to 2 GB), your speed is throttled. The key difference lies in transparency: simpleSIM clearly states this threshold, whereas competitors hide it in fine print. Learn more in our guide on unlimited data eSIM plans.
If traveling for a short trip (1-3 days) with modest usage (messaging, email, GPS), a prepaid per-GB plan is more economical. For a trip lasting over 5 days with heavier usage (social media, streaming, hotspot), an unlimited plan is better suited and often more cost-effective. simpleSIM offers both options across most destinations, giving you complete choice.
