Who is behind the picks
About this site
One researcher, six providers, no operator affiliation. This page says who we are and what keeps the ranking honest.
What this is. A single-purpose guide to getting online in Vietnam. No hotel widgets, no flight deals, one question answered properly: which eSIM fits your trip, and when no eSIM does. The picks come from comparing every Vietnam plan of the six providers we can verify, on published facts: which network each one rides, prices, fair-use caps, hotspot rules, review records.
Why Vietnam needed its own site. Because the usual eSIM advice glosses over the thing that decides whether your phone works here. Vietnam has three national networks. Most travel eSIMs that name a partner name VNPT, one lists Viettel, and several name nothing. Viettel, which travelers rate best in the northern mountains, also sells its own tourist eSIM at the airport. A guide that ranks brands without telling you which network each one names is answering the wrong question. That page exists because of it.
Who runs it. An independent researcher who builds travel-connectivity guides. Not a mobile operator, not owned by or affiliated with any provider on these pages. When something here is wrong it gets fixed in the next update, and the methodology page shows exactly how the sausage is made, commission rates included.
Why trust a site with affiliate links? Do not, on our word alone. Check the receipts. Every price carries the date we verified it. Every network claim names the brand's own page as its source, and where a brand publishes nothing we write "not published" instead of repeating a blog. Our default pick pays us 12%, the lowest rate of the four brands we link. The biggest unlimited brand in the category sits in our tables unlinked and unmonetized. Each of our own partners gets at least one con in plain text. And an entire page tells travelers heading north about Viettel's own tourist eSIM, which earns us nothing. A site optimising for commissions would do none of that.
