Editorial policy

We write about eSIMs and we sell eSIMs. That is a conflict of interest, not a secret, and the point of this page is to say exactly how we handle it.

What we sell

Wanderly is a retailer of prepaid travel eSIM data plans. We make money when you buy one. Every comparison on this site is written by a company with a commercial interest in one of the options, including the pages comparing us to named competitors. Read them with that in mind, and check the methodology below for how we keep those comparisons factual.

Who writes this

Wanderly Technologies LLC, the California company that operates Wanderly, is responsible for the guides, comparisons and research published under our company name. These pages use a company byline. A named contributor is credited only when they actually take responsibility for the work. Our About page identifies the operator and business address. Send questions about a source or a correction through our contact page.

Where facts come from

  • Device behaviour — from the manufacturer. iPhone and iPad behaviour from Apple's own documentation, Android from Google and the specific handset maker. We do not infer what a phone does from what a similar phone does.
  • Carrier and network claims — from the carrier or the network operator. Where we cannot source a claim to an operator, we do not make it.
  • Regulatory claims — from the regulator. Roaming rules, registration requirements and similar vary by country and change; we cite the authority rather than a secondary article about it.
  • Data consumption figures — from the service being measured, at its default quality on a cellular connection. The rates behind the travel data calculator are listed with their sources on that page.
  • Our own prices and plans — from the retail catalogue. Destination plan selectors show current offers. The price index publishes dated snapshots of a defined subset of our catalogue. Its observation date and scope let you distinguish a research figure from a current offer.

Prices and availability

Plan prices, allowances and validity can change. Check the selected plan and final checkout total before buying. Research snapshots retain the prices observed for that edition; they are not a promise that an offer is still available. Prices are retail USD and exclude tax unless a page says otherwise. A quoted research figure should identify its edition, observation date and methodology.

Corrections

If something here is wrong, we want to fix it rather than defend it. Tell us through the contact page and point at the claim. Substantive corrections to a factual page are made in the page itself rather than appended as a note, because the page is what people read; where a correction changes the meaning of a published figure, the research page carries the change in its methodology section.

AI and automation

We use software to generate and maintain parts of this site, particularly pages derived from the plan catalogue. What we do not do is publish a factual claim that no one has checked against the source above. The distinction that matters is not whether a tool was involved; it is whether the claim is true and sourceable.
