Speed

3 to fix94

  • Render-blocking requests

    900 ms

    1 file blocks the first paint until they finish downloading. Deferring or inlining it could save about 900 ms.

  • 2 third-party services on the page

    2 third-party services load with your homepage (Shopify and JSDelivr CDN), adding 1.0 MB and 374 ms of main-thread time.

  • Shopify adds 374 ms

    374 ms

    Shopify costs a phone 374 ms of main-thread work and 1.0 MB of downloads while your page loads. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

  • Improve image delivery

    111 KiB

    2 images could be 111 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

  • Reduce unused JavaScript

    24 KiB

    About 24 KiB of JavaScript is downloaded but never used on this page.

  • Use efficient cache lifetimes

    22 KiB

    1 file is served with short cache lifetimes, so returning visitors download them again (22 KiB).

  • Chained critical requests

    Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

3 checks passed

  • Mobile performance score: 94

    94/100

    Your mobile performance score is 94. That is in Google's “good” band (90 and up).

  • Main-thread work: 1.1 s

    A phone's processor spends 1.1 s on main-thread work while loading, 506 ms of it running JavaScript. That is comfortably low.

  • Server response: 5 ms

    5 ms

    Your server sent the HTML in 5 ms, well inside Google's 600 ms guideline.

Core Web Vitals

8 to fix67

  • Fails Core Web Vitals for real visitors

    Real Chrome users on phones do not pass Google's Core Web Vitals on this page (28-day field data from the Chrome UX Report (opens in a new tab)). Google uses this in ranking.

  • Real-user INP: 233 ms

    233 ms

    Real visitors wait 233 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

  • Tap response (INP) got 60% slower for real visitors

    +60%

    Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 154 ms to 239 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

  • Real-user FCP: 2.2 s

    2.2 s

    Real visitors see the first content after 2.2 s (75th percentile). Good is under 1.8 s.

  • Real-user TTFB: 1.7 s

    1.7 s

    Real visitors wait 1.7 s for your server to start answering (75th percentile). Good is under 800 ms.

  • Cumulative Layout Shift: 0.118

    0.118

    The layout shifts by 0.118 while loading, so content jumps under the reader's thumb. Good is under 0.1.

  • First Contentful Paint: 1.8 s

    1.8 s

    The first text or image appears after 1.8 s on a phone. Good is under 1.8 s.

  • 2 images without width and height

    2 images have no width and height attributes, so the layout jumps as each one loads.

7 checks passed

  • Real-user LCP: 2.5 s

    2.5 s

    Real visitors wait 2.5 s for the largest content to appear (75th percentile). Good is under 2.5 s.

  • Real-user CLS: 0.00

    0.00

    For real visitors the layout shifts by 0.00 (75th percentile). Good is under 0.1.

  • Largest content (LCP) got 21% faster for real visitors

    -21%

    Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 3.5 s to 2.7 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

  • Speed Index: 3.0 s

    3.0 s

    Visually, the page fills in at 3.0 s (Speed Index), inside the 3.4 s “good” threshold.

  • Largest Contentful Paint: 1.8 s

    1.8 s

    Your largest element renders in 1.8 s on a phone, inside Google's 2.5 s “good” threshold. The largest element is the text “International eSIMs & Travel SIM Cards”.

  • Total Blocking Time: 0 ms

    0 ms

    Scripts block the page for only 0 ms while loading. Good is under 200 ms.

  • Time to Interactive: 1.8 s

    1.8 s

    The page is fully interactive after 1.8 s.

Images and page weight

100

  • About 0.4 g of CO₂ per visit

    0.39 g

    By the Sustainable Web Design model, a visit to your homepage emits about 0.39 g of CO₂e: 46.7 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

4 checks passed

  • Page weight: 1.4 MB in 84 requests

    1.4 MB

    Your homepage downloads 1.4 MB in 84 requests on a phone: images 924 KiB (43), scripts 272 KiB (31) and other files 120 KiB (4). That is a lean page.

  • Images use modern formats

    Every sizeable image is WebP, AVIF or SVG.

  • Images load when needed

    Images below the first screen wait until the visitor scrolls to them.

  • Images are sized for phones

    No image is downloaded at more than three times the size it is drawn on a phone.

Accessibility

6 to fixGoogle 8792

  • Certain ARIA roles must contain particular children (1 element)

    Certain ARIA roles must contain particular children: 1 element on the page fails this check, rated critical by axe-core.

  • 1 text element with low contrast

    1 text element doesn't have enough contrast against the background to read easily, especially outdoors on a phone.

  • All page content should be contained by landmarks (1 element)

    All page content should be contained by landmarks: 1 element on the page fails this check, rated moderate by axe-core.

  • Hidden but focusable

    1 element hidden from screen readers can still receive keyboard focus.

  • 1 form field without a label

    1 form field has no label, so screen readers announce an empty box and autofill guesses.

  • Alternative text of images should not be repeated as text (8 elements)

    Alternative text of images should not be repeated as text: 8 elements on the page fail this check, rated minor by axe-core.

2 checks passed

  • Every image has alt text

    All 19 images in the HTML carry an alt attribute.

  • 41 automated accessibility rules passed

    axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 45 WCAG 2.2 A/AA and best-practice rules on the phone render: 41 passed and 4 failed. 2 mores need a person to judge. Automated rules catch about a third of accessibility problems; the rest need manual testing.

SEO

2 to fixGoogle 10092

  • Structured data has 1 problem

    Structured data found (BreadcrumbList, FAQPage, MobileApplication and Organization) but with 1 problem, for example “Service: no offers (price) block”.

  • No XML sitemap

    No XML sitemap at https://simcorner.com/sitemap_index.xml, so Google discovers your pages only by following links.

  • 13 internal links, 0 external

    The homepage links to 13 pages on simcorner.com and 0 external pages.

6 checks passed

  • Meta description: 153 characters

2 checks passed

  • AI answer engines may read the site

    https://simcorner.com/collections/global-esim, https://simcorner.com/collections/europe-esim, https://simcorner.com/collections/asia-esim and https://simcorner.com/collections/usa-esim took over 3 s to send their HTML from our server.

Content and conversion

5 to fix50

  • No call to action on the first screen

    On a phone, there is no call to action on the first screen: visitors have to scroll to find out what to do next.

  • No calls to action

    We found no call-to-action buttons or links (such as “Book a demo” or “Get a quote”) anywhere on the homepage.

  • No analytics detected

    No analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.

  • No direct contact details

    No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

  • Only about 56 words

    The homepage has only about 56 words of visible text; thin pages give Google and first-time buyers little to go on.

  • No risk reducer

    No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.

2 checks passed

  • 1 short form

    A short form (1 field at most) is right on the homepage.

  • Social proof on the page

    Social proof on the homepage: a star rating and 6 trust badges.

Privacy and tracking

  • No consent tool detected

    No known cookie consent tool loads with the page. Some sites build their own banner, and some only show one to visitors from the EU.

  • 1 other company contacted

    Loading the homepage contacts 1 host run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.

1 checks passed

  • No known trackers before consent

    No known advertising or analytics trackers load before a visitor clicks anything (measured from a US location before any click).

Security, domain, email and software versions

The security, domain and email checks, software and plugin versions, and any app with a known security problem are visible only to people at simcorner.com, because details like these could help someone attack a site. Every review keeps them private, whatever they found.

Apps on your store

No apps were seen in the code your storefront loads.
