Connectivity along the Mekong River during the scenic slow boat trip from Huay Xai to Luang Prabang can be an adventure in itself. While WorldESIM leverages top local networks, signal strength will fluctuate. You'll generally find good 4G/LTE coverage when passing by towns and at your overnight stop in Pakbeng. However, expect intermittent or no signal in more remote stretches of the river, especially away from populated areas. It's a perfect opportunity to disconnect and enjoy the stunning riverside scenery!
