GoSIM website — browse and buy eSIMs on the web

Context

Travellers often shop for an eSIM on a laptop before a trip, not in an app store. The site answers three questions right away — is my destination covered, how much, will it work on my phone — and lets people buy without installing anything.

Role

Main developer of the GoSIM pages inside the GO website: plan selector and checkout, destinations and devices pages, help and partner pages, translations.

Challenge

• Real prices — plans and prices come from the same API as the app and vary by country and currency.
• Buying on the web — checkout must respect the payment methods available for each currency.
• Trust — visitors need to confirm compatibility before paying.

Approach

Plan selector on the live catalogue

Country/region picker showing unlimited and fixed plans with real prices from the GoSIM API; switching currency reloads packages and payment methods.

Web checkout

Browser purchase flow with the providers available for the selected currency, including Airwallex.

"Will it work?" answered

Searchable, brand-filtered devices page and a destinations page covering 190+ countries — the same questions the app answers with the compatibility library.

Part of the GO site

Shares the GO website's Nuxt codebase, i18n and SEO setup while keeping GoSIM's own visual identity.

Results

• Coverage check, real prices and purchase without installing the app.
• One source of truth for plans and prices across web and mobile.
• Help, device and partner pages that reduce support load.
