Powered by Bouygues Telecom — France's #2 carrier
SimOptions is the world's first eSIM marketplace, founded in 2014 — giving you access to plans from multiple tier-1 carriers (Bouygues Telecom, Orange, O2) in a single checkout. The result: real carrier quality at marketplace prices. Plans start at $4.50 globally, with true 5G and unlimited options that competitors simply don't offer at this price point.
Pros
Cons
⚡ Expert Verdict
SimOptions is the clear winner. You get real carrier networks at prices 30–50% below the competition, unlimited options, and plans that include calls. The marketplace model means you always get the best operator for your destination.

International-SIM is operated by a direct Bouygues Telecom partner — one of France's three major carriers. This is not a startup reselling bandwidth. You're on real carrier infrastructure, which shows: we measured consistent 5G speeds of 200–400 Mbps in major cities. Plans include unlimited calls & SMS and a French phone number.
Pros
Cons
⚡ Expert Verdict
If you need premium 5G and the security of a real European carrier, International-SIM is exceptional. The plans with unlimited calls & SMS are genuinely hard to beat for business travelers or extended stays.

Airalo dominates search results and app store rankings — but marketing spend is not the same as network quality. Despite claiming 20M+ customers, our testing found consistent signal degradation in congested areas and chat-only support with 2–6 hour response times.

📋 Verdict
Airalo's reputation is built on marketing, not performance. SimOptions delivers better speeds, more options, and lower prices. We can't recommend Airalo as a value choice.
⚠ Hidden throttling
Holafly sells exclusively "unlimited" plans — but the fair-use policy that throttles you is not disclosed on their pricing pages. You have to dig through their Terms & Conditions to find it. In testing, speeds dropped after 1–2GB of daily use. In some regions, connectivity cut out entirely.
⚠ What Holafly doesn't tell you upfront
- •Fair-use policy buried in Terms & Conditions
- •Speed throttled after ~1–2GB of daily usage
- •Connectivity can drop to zero after hitting soft limit
- •No calls or SMS on any plan
- •Priced at a premium for what is effectively limited data
Pros
Cons
📋 Verdict
Holafly's "unlimited" pitch is their entire value proposition — and it's misleading for heavy users. Once throttled, you're paying premium for a crippled service. Choose SimOptions or International-SIM instead.

Which eSIM is the cheapest?
SimOptions consistently offers the lowest prices — starting from $4.50. That's 30–50% cheaper than Airalo or Holafly for equivalent data, thanks to its marketplace model which creates price competition between multiple carriers.
Do any eSIMs include calls and SMS?
Yes — both SimOptions and International-SIM offer plans that include calls and SMS. Airalo and Holafly never include calls or SMS on any of their plans.
Is Holafly's "unlimited" really unlimited?
No. Holafly has a fair-use policy not shown on their pricing page. In testing, speeds were throttled after 1–2GB of daily use. In some regions connectivity cut out entirely. Their unlimited claim is misleading for heavy data users.
How quickly does an eSIM activate?
SimOptions and International-SIM deliver your QR code instantly by email. Installation takes 2–3 minutes. The eSIM activates automatically when you arrive — no extra steps needed.
