Travel tip. Travelling from northern Thailand into Laos? Consider taking the two-day slow boat journey along the Mekong River, via Pakbeng to Luang Prabang. Along the way, you'll pass lush mountains and traditional riverside villages. Download your maps and accommodation details beforehand, so you're prepared even when mobile coverage is limited.

Questions

Questions about this eSIM

Usually not. Keep data roaming on for the eSIM line and network selection on automatic. After the border, your phone then picks a network in the new country by itself. No connection after a few minutes? Turn airplane mode on and off again.
