Phone Hotspot Abroad: Connect a Laptop, Tablet or Family (2026)
How to use your phone as a hotspot abroad: turn it on for iPhone and Android, pick the right SIM line, stop laptop data drains, and keep it secure and cool.
ArriGo team 10 min read Updated
To use your phone as a hotspot abroad, set your travel eSIM as the phone’s mobile data line, then turn on Personal Hotspot on iPhone or Wi-Fi hotspot on Android and join it from your laptop or tablet like any Wi-Fi network. Before you connect a laptop, mark the connection as metered or low-data so it does not burn through your plan with updates and cloud sync.
A phone hotspot is the simplest way to get a laptop online in a café, a train or a rental with weak Wi-Fi. It also has quirks that home Wi-Fi does not: it drains the battery, it can make the phone hot, and a laptop will treat it as unlimited unless you change two settings. This guide covers each step, from turning the hotspot on to the laptop checklist that saves the most data.
Key takeaways
- The hotspot shares whichever line is your phone’s mobile data line, so select the travel eSIM first.
- Most ArriGo plans allow hotspot; the plan page shows it under “Coverage & networks”.
- On a laptop, mark the hotspot as a metered connection (Windows) or turn on Low data mode (Mac) before you do anything else.
- Keep the phone plugged in, out of the sun, and protected with a strong hotspot password.
How does a phone hotspot work abroad?
Apple describes Personal Hotspot as using your phone’s cellular connection to create a temporary, portable Wi-Fi network. Android calls the same thing tethering. Either way, your laptop, tablet or a family member’s phone connects to your phone over Wi-Fi, Bluetooth or a USB cable, and all of their traffic goes out over your phone’s mobile data.
Abroad, that mobile data should come from a local or travel plan, not your Canadian carrier. If your Canadian line is the one sharing data, every gigabyte the laptop pulls is roaming data. Our comparison of Bell, Rogers and Telus roaming with an eSIM shows what those daily charges look like.
Is hotspot allowed on a travel eSIM?
It depends on the plan. Google’s guide to sharing a mobile connection on Android warns that some carriers limit tethering or charge extra for it, and Apple says the same about Personal Hotspot. Most ArriGo plans allow hotspot, and each plan page shows it under “Coverage & networks”, so check there before you buy if a laptop is part of the trip.
How to turn on Personal Hotspot on iPhone
Apple’s guide to setting up Personal Hotspot keeps the steps short:
- Open Settings and tap Personal Hotspot (or Cellular, then Personal Hotspot).
- Turn on Allow Others to Join.
- Note the Wi-Fi Password shown on that screen, or tap it to change it.
- On the laptop or tablet, choose your iPhone’s name from the Wi-Fi list and enter the password.
You can also connect by USB (tap Trust on the iPhone when asked) or by Bluetooth. Apple adds that devices signed in to the same Apple Account, or in the same Family Sharing group, can join through Instant Hotspot without typing the password. If a device will not connect, Apple suggests updating and restarting both, then trying the Maximize Compatibility switch in the hotspot settings.
The number of devices that can join depends on your carrier and iPhone model, according to Apple.
How to turn on a hotspot on Android, Samsung and Pixel
On most Android phones, including Pixel, Google’s steps are:
- Swipe down from the top of the screen, then touch and hold Hotspot.
- Turn on Wi-Fi hotspot. Tap the hotspot entry to see or change its name and password.
- On the other device, choose the hotspot name and enter the password.
Google says up to 10 other devices can connect, and the same menu holds Bluetooth tethering and USB tethering. One limit to know: Google notes that Mac computers cannot tether to an Android phone over USB, so a MacBook should join over Wi-Fi.
On a Samsung Galaxy, Samsung Canada’s guide to using a mobile hotspot uses Settings > Connections > Mobile Hotspot and Tethering > Mobile Hotspot. The same screen lets you show a QR code for other devices to scan, and set a data limit in MB under Mobile data shared today, which is a useful brake when a laptop is connected.
Which SIM does the hotspot use when you have two lines?
Most travellers abroad have two lines on one phone: the Canadian SIM that keeps their number, and the travel eSIM for data. The hotspot shares the phone’s mobile data connection, and Apple’s Dual SIM guide is clear that only one number at a time can use cellular data. Whatever line you set for data is the line your laptop will use.
So before you turn the hotspot on:
- iPhone: go to Settings > Cellular > Cellular Data and choose the travel eSIM.
- Android: pick the travel eSIM as the mobile data SIM in your SIM settings.
On iPhone, also look at Allow Cellular Data Switching. Apple explains that it lets the phone use data from both plans depending on coverage. Abroad, you want data to come only from the travel eSIM, so leave it off. If you are not sure the line is set correctly, step 2 of our guide to fixing an eSIM that is not working abroad shows the screens for iPhone, Samsung and Pixel, and our dual SIM guide explains how to keep your Canadian number for texts while the eSIM carries data.
How much data does a laptop use on a hotspot?
More than you expect, and mostly in the background. A phone is built to save data on mobile networks. A laptop usually assumes it is on unlimited home internet: it downloads operating system updates, syncs cloud folders, updates apps and backs up photos as soon as it finds a connection.
The fix is not to stop using the laptop, but to stop it doing those jobs on your plan. The tasks that cost the most are:
- Operating system updates, which can run to several gigabytes.
- Cloud sync of folders and photo libraries after days offline.
- Video calls, especially with the camera on in high quality.
- Streaming and large downloads, including offline video.
For figures by app and a data table by type of trip, see our guide to how much data you need when travelling; it has a dedicated row for remote work and laptop hotspot use. If two or more people will share the connection, our guide to sharing mobile data with family abroad compares one hotspot with an eSIM for each phone.
Laptop settings to change before tethering
Spend five minutes on these at home, before the first time your laptop joins the hotspot. They are the biggest single saving you can make.
On a Mac
- Join your phone’s hotspot once.
- Choose Apple menu > System Settings, then click Wi-Fi in the sidebar.
- Click Details next to the hotspot network and turn on Low data mode. Apple’s Wi-Fi settings guide for Mac describes it as reducing your data use on that network.
- In the same Wi-Fi settings, check Ask to join hotspots. Setting it to Ask to Join or Never stops the Mac joining your iPhone’s hotspot on its own when no known network is around.
- Pause or delay large uploads in your cloud and photo apps, and turn off automatic app updates for the trip.
On Windows 11
- Join your phone’s hotspot once.
- Open Settings > Network & internet > Wi-Fi and select the hotspot.
- Turn on Metered connection. Microsoft’s guide to metered connections in Windows says Windows Update then downloads only priority updates, and some Microsoft Store downloads may pause.
- In Windows Update > Advanced options, make sure Download updates over metered connections is off.
- Pause sync in your cloud storage app while you are on the hotspot.
On the phone and tablet
The phone sharing the hotspot can save data too. Apple’s guide to Low Data Mode on iPhone shows how to turn it on per line: with Dual SIM, go to Settings > Cellular, tap the travel eSIM and turn on Low Data Mode. A tablet joining the hotspot can use Low Data Mode for that Wi-Fi network, from the Info button next to the network name.
| Device | Setting | Where to find it |
|---|---|---|
| Mac | Low data mode | System Settings > Wi-Fi > Details |
| Mac | Ask to join hotspots | System Settings > Wi-Fi |
| Windows 11 | Metered connection | Settings > Network & internet > Wi-Fi > hotspot |
| Windows 11 | Download updates over metered connections: off | Windows Update > Advanced options |
| iPhone (sharing) | Low Data Mode for the travel line | Settings > Cellular > travel eSIM |
| iPad or iPhone (joining) | Low Data Mode for the hotspot network | Settings > Wi-Fi > Info button |
| Samsung (sharing) | Data limit for the hotspot | Mobile Hotspot > Mobile data shared today |
Tip: Back up your laptop and phone to the cloud before you leave. Apple notes that some features that need Wi-Fi, such as iCloud backup, may not work while you are using Personal Hotspot.
Battery and heat: how to keep a hotspot running
Sharing a connection keeps the phone’s radios working hard, and that costs battery. Google’s advice is to plug in your devices while tethering, turn tethering off when you are done, and switch on the option that turns the hotspot off automatically when nothing is connected, if your phone has it.
Heat is the other limit. Apple’s page on iPhone operating temperatures says the phone is designed for ambient temperatures between 0 and 35 °C, and that using it in very hot conditions can permanently shorten battery life. It also warns against leaving a device in a parked car. A sunny beach or a hot terrace can push past that range.
Practical habits that help:
- Keep the phone in the shade, out of a pocket and off hot surfaces while it shares.
- Plug the phone into a wall charger or power bank while it shares, as Google suggests.
- Pack a power bank for days away from a socket.
- Turn the hotspot off as soon as the laptop is done, rather than leaving it on all day.
How to keep your phone hotspot secure
A hotspot only you can join is one of the better ways to work on the road, especially compared with crowded public networks. Our guide to staying safe on airport and hotel Wi-Fi covers those risks in more detail. To keep the hotspot itself private:
- Never turn off the password. Android lets you set the hotspot’s security to None; do not use it.
- Use a strong password. On iPhone, Apple requires at least eight ASCII characters; longer and random is better. Change it after a trip if you shared it with people outside your group.
- Choose the strongest security type your devices support. For Wi-Fi networks in general, Apple’s recommended Wi-Fi settings call WPA3 Personal the most secure option, with WPA2/WPA3 Transitional for compatibility with older devices. If your Android phone offers a choice for its hotspot, pick WPA3 when every device that joins supports it.
- Turn it off when you are done. Google recommends switching tethering off when you finish, and turning on automatic switch-off when nothing is connected if your phone offers it. A hotspot that is off cannot be joined.
- Rename the hotspot if its name shows your full name. On iPhone, the hotspot uses the phone’s name under Settings > General > About > Name.
Hotspot or a separate eSIM for each device?
A hotspot is ideal for a laptop or tablet that has no SIM of its own, and for a couple who stay together all day. It is weaker for a family that splits up, because everyone else loses internet the moment the phone sharing it walks away.
For phones, a separate eSIM each is often simpler: each ArriGo eSIM installs on one phone only, and you can buy up to 10 in one order and send each QR code to its own email address. Check which phones in your group qualify with our eSIM compatibility checker.
Your next step
Before the trip, set up the laptop checklist above, confirm hotspot support on your plan page under “Coverage & networks”, and choose a plan with room for the laptop’s share of data. If you are crossing borders, a regional or global plan keeps one hotspot running across countries:
For single destinations, start from our destinations list, for example the United States or Mexico. If the hotspot will not share data once you arrive, our help centre is the place to ask.
Frequently asked questions
Can I use my phone as a hotspot with a travel eSIM?
Yes, if the plan allows tethering. Most ArriGo plans do, and each plan page shows hotspot support under Coverage and networks. Set the travel eSIM as your phone's data line, then turn on the hotspot as usual.
How many devices can connect to a phone hotspot?
Google says an Android phone can share its connection with up to 10 devices. On iPhone, Apple says the limit depends on the carrier and the iPhone model.
Why does my laptop use so much data on a hotspot?
A laptop treats a hotspot like home Wi-Fi unless you tell it otherwise, so it downloads system updates, syncs cloud folders and refreshes apps in the background. Marking the connection as metered on Windows or turning on Low Data Mode on a Mac reduces this.
Does using a hotspot drain the phone battery?
Yes, noticeably. Google recommends plugging the phone in while tethering and turning the hotspot off when you are finished. A power bank and a short cable are worth packing.
Is a phone hotspot safer than hotel Wi-Fi?
A hotspot protected with a strong password only lets in the devices you approve, which is a real advantage over shared networks. Use WPA3 or WPA2 security where your phone lets you choose, and never set the hotspot to no password.
Which SIM does the hotspot use if I have two lines?
The hotspot shares your phone's mobile data connection, and only one line handles data at a time. Make sure the travel eSIM is selected as the data line so your Canadian line is not used for roaming data.
