Comparing eSIM providers in a way that helps you
Price-only comparisons mislead, because the products are not the same thing.

Quick answer
- Compare price per gigabyte per usable day, alongside the speed terms and top-up rules.
- A lower price with a lower speed cap or shorter validity may not be cheaper for your trip.
Comparing data plans is harder than it looks: two similarly priced plans can differ in validity, full-speed cap, country list and top-up rules, all of which shape the experience more than the headline price.
The criteria to use
- Price per gigabyte per day you can actually use on your trip
- The full-speed cap and what happens beyond it
- The covered country list against your real route
- Top-up and extension terms
- How clear the refund policy and support route are
Price per gigabyte only means something if the validity covers your trip. Ten gigabytes expiring in seven days is not the same product as ten over thirty, even at the same price.
Common traps
- Comparing entry prices without noticing different validity
- Trusting the word unlimited without finding the full-speed cap
- Inferring coverage from a region's name instead of reading the country list
- Treating someone else's speed report as decisive when speed varies by place and time
Pros
- Comparing against your own usage decides faster and more accurately
- Reading the terms first prevents most later complaints
Cons
- An exhaustive comparison table costs a lot of time and dates quickly
- User speed reports cannot be compared directly with each other
FAQ
Why do you not rank providers?+
Because best depends on the trip, and we will not label something best because it pays us more. We give the criteria and the facts instead.
Should I trust online speed reviews?+
Use them as context, not as a decision. A measurement in one city at one moment says little about where you are going.
