Hotspot data use on a laptop
A laptop on your phone's hotspot uses about 100 MB an hour for browsing and email. A video call takes about 800 MB an hour, and HD streaming about 3 GB.
Laptops use more than phones for the same task because websites send them full-size pages and video. They also run updates and cloud sync in the background as soon as they find a connection.
How long 1 GB and 10 GB last on a hotspot
One gigabyte gives a laptop about 10 hours of browsing and email, 1 hour 15 minutes of video calls or 20 minutes of HD video.
A 10 GB plan holds about 100 hours of browsing, enough for a working trip if you keep video calls short. An hour-long video call every workday uses 4 GB a week on its own.

Hotspot data for a one-week and a two-week trip
Two hours of laptop browsing a day uses about 1.4 GB a week, or 2.8 GB over two weeks. Add an hour of video calls each day and the week comes to about 7 GB.
Remote workers on the road should take a 20 GB plan or an eSIM with unlimited hotspot sharing. Check the hotspot limit first: some unlimited plans cap sharing at 1 GB a day.
Turn on a hotspot on iPhone and Android
On iPhone, open Settings, tap Personal Hotspot and turn on Allow Others to Join. On your laptop, pick the iPhone from the Wi-Fi list and enter the password shown on the phone.
On Android, open Settings, then Network and internet (Connections on Samsung), then Hotspot and tethering, and turn on Wi-Fi hotspot. Set the hotspot to use the travel eSIM's data line, which is the line your phone uses for mobile data.
Stop your laptop using hotspot data
Mark the hotspot as a metered connection. On Windows, open the Wi-Fi network's properties and turn on Metered connection, which pauses most updates. On a Mac, turn on Low Data Mode in the Wi-Fi network's details.
Pause iCloud, Google Drive, Dropbox and OneDrive sync while you are on the hotspot. Set video calls to standard quality and close browser tabs that play video by themselves.
