iRoamly

iRoamly takes a flexible approach to data pricing with daily-rated and fixed-plan options. Their coverage spans 140+ countries, so Vietnam fits comfortably within a single subscription setup. The unlimited hotspot allowance means tethering to a laptop or tablet doesn't hit a secondary cap, useful if you're working remotely or uploading travel content.

This platform suits travelers who value flexibility and might benefit from coverage across multiple regions without managing separate eSIMs. The daily-rate option appeals if you can't predict exactly how many days you'll be in Vietnam or if your stay might stretch unexpectedly. The unlimited hotspot differentiates from plans that throttle tethering, making it practical for anyone running a digital nomad routine.
