About alter.sg
alter.sg is an independent comparison site for Singaporean travellers. It compares the tools you actually need for a trip — eSIMs, multi-currency cards and airport lounge access — and recommends what to use based on where you’re going.
It exists for one reason: comparing this stuff in Singapore usually means fighting through cluttered, ad-heavy, out-of-date websites. alter.sg is the opposite — every page leads with the answer, prices are shown in SGD, and there are no pop-ups.
The site earns affiliate commission on some outbound links. That never changes a ranking or a verdict — see our affiliate disclosure and how we compare for the full picture.

Marcus Tan
Editor, alter.sg
Marcus Tan is the editor of alter.sg. He started the site after one too many trips spent comparing eSIMs, travel cards and lounge passes on cluttered, out-of-date Singapore websites. Every recommendation here is checked against the provider's own pricing, shown in SGD, and dated so you know how fresh it is.
