KnowRoaming

KnowRoaming brings fifteen years of roaming expertise to the table. They've been operating since 2009, which means they've built established relationships with carriers across 200+ destinations. Vietnam data plans start at $4.50, sitting in the moderate range of the market, and the long operational track record suggests stable service and reliable coverage.

This works well for travelers who value proven reliability and don't mind paying slightly more for a provider with a track record. The company's longevity means they're unlikely to shut down mid-year, a real concern with newer fly-by-night eSIM platforms. If you're taking a leisurely regional tour and want the peace of mind that comes from using a provider that's been in business for over a decade, KnowRoaming's experience is a tangible asset.
