Content update policy
What triggers a review of each content type, and when we retire a page.
Last updated September 5, 2026

eSIM information ages quickly: prices, OS menus and supported handsets all move. We therefore review each content type when its own kind of source changes.
This table sums up who answers for each content type, what it is checked against, and what triggers a review. Every article is written by one of our two co-founders and reviewed by the other.
| Type | Owner | Checked against | Review trigger |
|---|---|---|---|
| Prices and plans | Both co-founders | Supplier catalogue | Provider price change |
| Installation guides | Both co-founders | Manufacturer documentation | Major iOS or Android release |
| Device tables | Both co-founders | Official manufacturer specs | Manufacturer announcement |
| Destination pages | Both co-founders | Catalogue and operator announcements | Local network change |
| Travel guides | Both co-founders | Official government pages | Travel rules change |

When we retire a page
- The plan is discontinued with no replacement.
- The content is merged into a more complete page.
- The page is too outdated to fix, in which case we redirect to the closest useful page.
Why content ages at different speeds
eSIM information does not age uniformly. Plan prices can move week to week as providers adjust them, while an explanation of what eSIM actually is barely changes across several years. Setting one review cycle for every page would not make sense: fast-moving pages would go stale while waiting their turn, and slow-moving pages would be reviewed far more often than they need.
So rather than one fixed schedule, we review a page when its primary source changes, when a reader reports a problem, or when we notice something no longer matches. A brand-new page and an older one in the same category follow the same rule.
Prices and plans: the fastest-moving content
Plan prices on a product page come from the supplier catalogue, because price is the figure that most directly affects a buying decision and it moves most often. When we refresh the catalogue, any price or data-volume change the provider made carries through to the relevant product page, and the updated date on a destination page moves with that refresh.
One thing worth knowing: the price shown on a product page may differ from the one you remember seeing last time, because the catalogue may have been refreshed in between. The price that actually binds is the one shown at the moment you check out, not the one you recall from an earlier visit.
Install guides and OS releases
Install guides follow the help pages that handset manufacturers publish. When iOS or Android ships a major release that moves the settings menu, we review the affected guide against the manufacturer's updated documentation. A guide that points to the wrong menu location loses the reader at the very first step.
Device tables and new handsets
Device compatibility tables are reviewed when a manufacturer announces a new model, not on a fixed schedule, because new releases do not arrive evenly across the year; some months bring several, others bring none. We follow manufacturer announcements instead of a rigid calendar.
A new model is added to the table only once official specifications confirm eSIM support. If a page does not yet list a new model, that does not mean it fails; it may mean we have not found confirming specifications yet, or the model is new enough that it has not reached the front of the review queue.
Destination pages and local networks
Each destination page is reviewed when a local operator announces a significant change, such as a network technology shift or a coverage adjustment, and when the supplier catalogue for that country changes, with the updated date moving to match, because destination-page information affects the buying decision of someone travelling in the next few days.

Travel guides and travel rules
General travel guides, such as packing advice or preparation tips, age more slowly than technical content, so we review them when a source on the page changes or a reader writes in. But where an article references a visa or customs rule that a government agency has since changed, we correct it as soon as we know, because a travel rule affects a reader's entry into a country directly.
Slow-moving reference pages
Basic terms and definitions, such as what eSIM is or how an eUICC differs from a physical SIM, barely change meaning across years. This kind of page is reviewed less often than others, but that does not mean it is left untouched forever. We recheck it when the underlying technical standard changes, or when a reader points out that the existing wording is genuinely misleading.
What the dates on a page mean
| Date field | What it means | What it does not mean |
|---|---|---|
| Published | The first day this page went live on the site | Does not mean the content still reads exactly as it did that day |
| Updated | The date the text, figures, or structure of the page were last edited | Does not mean every fact on the page was rechecked that day; only part of it may have changed |
| Source date | The date shown next to the publisher in the page's Sources list, when we last checked that source | Does not mean the price shown right now matches that date; the binding price is the one at checkout |
What happens between reviews
A source changing is not the only reason a page gets corrected. If someone reports an error through our corrections policy, we check and fix it straight away. Reader reports are a second safety net alongside our own checks, not a replacement for them.
What a review actually involves
- 1Pick the pages to reviewPages whose source changed, pages a reader reported, and pages where the supplier catalogue changed.
- 2Compare content against the primary sourceWe check whether what is written still matches the manufacturer, provider, or agency documentation.
- 3Check the displayed price against the supplier catalogueSo no stale figure survives from an earlier catalogue.
- 4Fix, or confirm no fix is neededIf something is off, we correct it. If everything still holds, the date beside each source we opened moves to today.
- 5Update the on-page date to match what actually happenedThe updated date only changes when content genuinely changed, not simply because someone opened and closed the page.
When we retire or merge a page
A page describing a discontinued plan with no replacement, or a page whose content has become duplicated by another and should be merged, gets retired or folded into the more complete page. When a page is retired or merged, we always set up a redirect to the closest relevant page, so a link you saved earlier does not land you on something that no longer exists.

Signals that trigger a review
| Signal | What it usually means | What we do |
|---|---|---|
| A provider changes plan pricing | The product page price is temporarily out of step with the real price | Fixed when we refresh the catalogue, without waiting for any other review |
| iOS or Android ships a major version | Settings menu positions may have moved | The relevant install guides are reviewed right away |
| An operator announces a network change | Coverage information on the destination page may be stale | The destination page is reviewed against the operator's announcement |
| A manufacturer announces a new model | The device table does not yet list it | Added once official specs confirm eSIM support |
| A reader reports the install guide does not work | The guide may be out of step with current devices or versions | Checked immediately under our corrections policy |
Who actually reviews each content type
Every article is written by one of our two co-founders, Bob Kanokphon Thongdee or Porsch Kunnipat Siramanakul, and reviewed by the other, whose name appears on the page under Reviewed by. Each content type is checked against a different kind of source: pricing against the supplier catalogue, install guides against handset manufacturers' documentation, and travel rules against official government pages.
Having the co-founder who did not write the page do the review makes it easier to catch what the writer missed, and means two named people answer for every published page.
Do heavily visited pages get checked more often
Not directly, no. We review a page when its source or the catalogue changes, or when a reader writes in. A low-traffic pricing page follows the same rule as a high-traffic one, because the risk of stale information harming a reader depends on how fast that type of information moves, not on how many people happen to visit that particular page.
That said, if a high-traffic page collects several problem reports in a short span, that is usually a trigger for a review as described in the signals table above, driven by the number of reports rising, not by the visit count itself.
What stays the same even after a page is reviewed
A review does not mean a page's tone or position shifts. What gets adjusted is whatever fact has gone stale, such as a price or a model list. Warnings about device limitations, or the disclosure of how we earn, stay exactly as they were no matter how many times a page gets reviewed, because those are not facts that expire; they are principles we hold to throughout.
When the GSMA standard itself changes
The technical definition of eSIM we cite from GSMA barely changes across years. But if the standard itself is genuinely revised, for example in how profile transfer between devices works, every related reference and glossary page is reviewed together, not one at a time, because these definitions are linked to each other and need to stay consistent as a set.
Standard-level changes are rare, but when they happen they usually touch several basic explanations at once, so we treat this as another kind of review trigger, alongside the signals table above.
Checklist: is the page you are reading current
- It shows an Updated date, and its Sources list gives each source's publisher and last-checked date
- The displayed price matches what appears at actual checkout
- The device table includes a model close to yours, not one several generations older
- There is no flag warning that a section is awaiting review
- If unsure, open the page directly rather than reading only the search-result snippet
FAQ
How would I know the price changed since yesterday+
Prices come from the supplier catalogue and can change after a page's updated date without a separate warning label. The price that binds is the one at checkout. If it looks very different from what you expected, tell us before you buy.
Who reviews each page+
Our two co-founders: one writes, the other reviews. Prices come from the supplier catalogue, while comparing content against sources, editing the wording, and deciding whether to retire or merge a page are done by the co-founders themselves.
I read an outdated page and it led me to buy the wrong thing. What can I do+
Tell us on LINE at https://lin.ee/skDPoNx (@esimonline) or email esimonline.asia@gmail.com, with the page link and your order number. We check whether the content was genuinely wrong, and whether your case falls under the refund policy.
What is the difference between the Updated date and a source date+
Updated is the date the text or structure was last edited. The date beside each entry in the Sources list is when we opened that source and confirmed it still matched what is written. The two do not always fall on the same day.
When a page is retired, what happens to the link I saved+
We always set up a redirect to the closest relevant page, so the old link never leads to a blank result. The destination content may not match everything you originally read, though, since it has been merged into a broader page.
Instagram and TikTok have no web share button, so we open your phone's share sheet or copy the link instead.
