Yes, you can share a travel eSIM's data with a laptop, a tablet or your kids' phones through your phone's hotspot: set the eSIM as your mobile data line, then turn on Personal Hotspot (iPhone) or Mobile Hotspot (Android). Two things limit it: some providers cap how much you can share, and every shared gigabyte comes out of the same allowance, so size the plan for everyone using it.
Here is how to set it up, what a laptop really uses, and the caps to look for before you buy.
Before you turn it on: the eSIM must carry your data
A hotspot shares the phone's mobile data connection. If your phone still uses your home line for data, the hotspot shares that line, and your home carrier bills roaming for it. So first:
- Make the eSIM your data line. iPhone: Settings > Cellular > Cellular Data, choose the travel eSIM. Samsung: Settings > Connections > SIM manager, choose the eSIM for Mobile data. Pixel: Settings > Network & internet > SIMs, set Mobile data to the eSIM.
- Turn on data roaming for the eSIM line only, and keep it off on your home line. A travel eSIM always connects through a local partner network, so it needs roaming on.
- Check the eSIM has data: open a web page on the phone itself before you share it.
If the eSIM is not installed yet, our guides for iPhone and Android cover it.
How to turn on the hotspot
iPhone
- Open Settings > Personal Hotspot (on some versions, Settings > Cellular > Personal Hotspot).
- Turn on Allow Others to Join and note the Wi-Fi password, or set your own.
- On the laptop or tablet, join the Wi-Fi network named after your iPhone.
A Mac or iPad signed in to the same Apple Account can join without the password, from its Wi-Fi menu. If an older laptop cannot see the network, turn on Maximize Compatibility on the same screen.
Samsung Galaxy
- Open Settings > Connections > Mobile Hotspot and Tethering.
- Turn on Mobile Hotspot, and tap it to see the network name and password.
Google Pixel
- Open Settings > Network & internet > Hotspot & tethering.
- Tap Wi-Fi hotspot and turn on Use Wi-Fi hotspot. The network name and password are on the same screen.
Both Android phones also offer USB tethering, which shares data over the charging cable and keeps the phone charged at the same time.
What a laptop uses, and how to stop it eating your data
A phone is careful with mobile data. A laptop is not: it assumes it is on home broadband. On a hotspot it may start system updates, sync your cloud drive and back up photos, all at once. Before you connect:
- Mac: System Settings > Wi-Fi, click Details next to the hotspot network, and turn on Low Data Mode.
- Windows: Settings > Network & internet > Wi-Fi, open the hotspot network's properties and turn on Metered connection. Windows then holds back most updates.
- Pause sync in iCloud, OneDrive, Google Drive or Dropbox while you are on the hotspot.
- Kids' tablets: turn off automatic app updates and video downloads before the trip, and download shows at the hotel on Wi-Fi.
Video is the big one. Streaming in high definition can use a few gigabytes an hour, so an evening of shows on a shared hotspot can use more than a day's normal phone data.
Hotspot limits on travel eSIMs
Providers handle sharing differently, so check before you buy:
- Holafly caps hotspot sharing on its trip plans: 1 GB a day when we reviewed it on 9 October 2026, and some destinations are reported lower. On a plan sold as unlimited, that cap matters more than the label if you work from a laptop.
- T-Mobile says data from its International Pass can be used for tethering. See our T-Mobile guide.
- Other providers usually state any hotspot rule in the plan details or their terms.
Whatever the provider, data you share is counted the same way as data you use on the phone. If hotspot use matters for your trip, read the plan details, or ask us at support@esimlounge.com before you buy: we answer every day from 07:00 to 23:00 Paris time, within 2 hours.
Which plan type works for sharing
How a plan counts data decides how far a hotspot can go. Our guide to fixed, daily or unlimited data explains each in full; for sharing, the short version is:
- Daily plans give a set amount each day. Our daily plans give 1.5 GB a day: enough for one phone, tight for a phone and a laptop. Once the day's allowance is used, speed drops until it resets.
- Unlimited plans give full speed for a set amount each day, then slower data. On our unlimited plans the plan card says "Full speed for the first 5 GB each day", and every device on the hotspot shares those 5 GB.
- Fixed plans give one total for the whole trip. Sharing just uses it up faster.
To put numbers on it: across our 30-country Europe plan, 7 days at 1.5 GB a day costs $11.99, and 7 days of unlimited data $19.99, or $29.99 for 15 days. For a family sharing one phone, or anyone working from a laptop, unlimited is the safer pick. Prices are on the Europe plan page and every destination page.
One shared plan, or one eSIM each?
A hotspot is the simplest way to cover a laptop or a tablet without a SIM. For several phones it has catches:
- The host phone has to stay close, within Wi-Fi range. That works in a hotel room, less well when teenagers head off on their own.
- The host phone's battery drains faster. Carry a power bank.
- Everyone shares one allowance, and one person streaming slows everyone.
If each traveler's phone supports eSIM, one plan per phone keeps each person online on their own. Compare the price of one unlimited plan with a daily plan for each phone: on our Europe plans, two 7-day daily plans cost $23.98 against $19.99 for one unlimited week.

FAQ
Can I use a travel eSIM as a hotspot?
Yes, on most plans. Set the eSIM as your mobile data line, turn on data roaming for it, then turn on Personal Hotspot on iPhone or Mobile Hotspot on Android. Some providers cap hotspot use, so check the plan details.
Does using a hotspot use more data?
The hotspot itself adds almost nothing, but the devices on it do. Laptops in particular download updates and sync files. Turn on Low Data Mode on a Mac or Metered connection on Windows, and pause cloud sync.
Does hotspot work on an unlimited eSIM?
It depends on the provider. Holafly caps sharing on its trip plans at about 1 GB a day. On our unlimited plans, full speed covers the first 5 GB each day across the phone and everything on its hotspot, then speed drops until the next day.
Why is my hotspot not working with my eSIM?
Check that the eSIM is your mobile data line and has data roaming on, and that the phone itself can open a web page. If the phone has data but the hotspot does not share it, restart the phone and turn the hotspot on again, then ask the provider whether the plan allows tethering.
Is it better to share a hotspot or buy an eSIM for each person?
For a laptop or tablet, share. For several phones that support eSIM, one plan each is usually more practical: nobody depends on the host phone's battery or range, and each person has their own allowance.
