Most Vuoly plans support hotspot and tethering, so you can share your eSIM data with a laptop or a travel companion's phone. Each product page lists this under Hotspot & tethering, so check there before you buy.
On iPhone
Make sure your Vuoly plan is selected under Settings > Cellular > Cellular Data.
Go to Settings > Personal Hotspot and turn on Allow Others to Join.
Connect the other device with the Wi-Fi password shown on that screen.
On Android
Make sure your Vuoly eSIM is set as the SIM used for data.
Go to Settings > Network & internet > Hotspot & tethering (on Samsung: Settings > Connections > Mobile Hotspot and Tethering).
Turn on Wi-Fi hotspot and connect the other device.
Keep an eye on data
Laptops use data quickly, especially with cloud backups and system updates running in the background. Video calls and streaming over a hotspot use the most. Check your remaining data as you go. See: How to check your data usage.
