You’ve just landed, your laptop needs Wi-Fi to confirm a booking, and the airport network wants €8 an hour. The fix is already in your pocket. Your iPhone can turn its mobile data into a private Wi-Fi network for your laptop, tablet, and travel buddies in under a minute - it’s called Personal Hotspot. Here’s how to set it up, screen by screen, plus the one thing that catches travellers out.

Check your iPhone is ready
Thirty seconds now saves a headache later
Before you tap anything, three things need to be true. Get these right and the rest is effortless - miss one and you’ll find Personal Hotspot greyed out and wonder why.
| Check | Where to look |
|---|---|
| Mobile Data is switched on | Settings › Mobile Data |
| Your plan or eSIM includes data & tethering | Your carrier or eSIM provider |
| You’re on iOS 16 or later (most iPhones since 2018) | Settings › General › About |
Switch on Personal Hotspot
Your phone becomes the router
Open Settings and tap Personal Hotspot (on some iPhones it sits under Settings › Mobile Data › Personal Hotspot). Flip Allow Others to Join to green, then tap Wi-Fi Password and set something at least eight characters long - plain letters and numbers only, as emoji or accented characters can stop some devices connecting.
In Settings, open Personal Hotspot, then switch on Allow Others to Join and set a Wi-Fi password.
How to use it
1Open Settings and tap Personal Hotspot.
2Toggle Allow Others to Join on (it turns green).
3Tap Wi-Fi Password and set a strong 8+ character password.
4Keep this screen open while you connect your first device.
Connect a device over Wi-Fi
The quick, everyday way
On your laptop, tablet, or a friend’s phone, open the Wi-Fi list and look for your iPhone’s name (something like “Robin’s iPhone”). Tap it, enter the password you set, and you’re online. A blue banner or a chain-link icon at the top of your iPhone confirms the hotspot is live.
Your iPhone appears at the top of the other device’s Wi-Fi list. Tap it and enter the password.
How to use it
1On the other device, open its Wi-Fi settings.
2Tap your iPhone’s name in the network list.
3Enter your hotspot password.
4Wait for the tick - you’re connected.
Connect over Bluetooth
Lighter on the battery
Bluetooth tethering sips less power than Wi-Fi, which is handy on a long train journey when your battery has to last. Speeds are slower, so it’s best for email and messaging rather than streaming.
How to use it
1Pair your laptop or tablet with your iPhone over Bluetooth.
2On the other device, choose to connect to the network via the paired iPhone.
3Keep both devices within a few metres of each other.
Connect over USB cable
The most stable connection
Plug your iPhone into your laptop with a cable for the fastest, steadiest connection - and it charges your phone at the same time. Ideal for getting real work done from a hotel desk.
How to use it
1Connect your iPhone to your laptop with its cable.
2On a Mac, pick the iPhone under Network settings. On Windows, make sure iTunes is installed.
3Tap Trust on your iPhone if prompted, and you’re online.
Hotspot not showing up? The fixes
Ninety percent of problems, solved
If another device can’t see your hotspot - common with older laptops - turn on Maximize Compatibility on the Personal Hotspot screen. It switches your hotspot to the more widely supported 2.4 GHz band so almost anything can find it. Speeds dip slightly, so switch it off once everything’s connected.
On the Personal Hotspot screen, switch on Maximize Compatibility so older devices can find your network.
Still stuck? Run through this
1Hotspot greyed out or missing? Check Mobile Data is on, then restart your iPhone.
2Device can’t see it? Turn on Maximize Compatibility and confirm Allow Others to Join is green.
3Connected but no internet? Toggle the hotspot off and on, and check you have signal and data left.
4Last resort: Settings › General › Transfer or Reset iPhone › Reset › Reset Network Settings.
Don’t let roaming wreck the bill
The catch most guides skip
A hotspot is only as good as the data behind it - and tethering burns through data fast. Stream a film to your laptop or back up your photos and you can clear a gigabyte in minutes. Do that on your home SIM abroad and you’re often paying roaming rates on every gigabyte. That’s how people land a three-figure phone bill.
| Activity (1 hour) | Rough data used |
|---|---|
| Browsing & email on a laptop | ~60-150 MB |
| Video calls (Zoom / FaceTime) | ~500 MB-1.5 GB |
| HD video streaming | ~1-3 GB |
| Photo & cloud backup | Varies - can be huge |
Goodbye SIM cards. Hello adventure.
Pair these steps with a SIMOVO eSIM and your next trip is genuinely friction-free. Pick a plan for your destination and install it in under a minute.

Personal Hotspot has been hiding in your iPhone for years - no download, no extra kit. Set a strong password, learn the Wi-Fi, Bluetooth, and USB options, and keep Maximize Compatibility in your back pocket for stubborn devices. Do all that on a travel eSIM rather than your roaming home SIM, and you’ve removed the one thing that turns a handy feature into a nasty bill.
Frequently asked questions
- Does using a hotspot cost extra?
- The feature itself is free, but it uses your data allowance. The real cost depends on your plan - and abroad, roaming rates can make it expensive unless you use a travel eSIM.
- How many devices can connect to an iPhone hotspot?
- Typically up to five at once, depending on your iPhone and carrier.
- Will a hotspot work on a plane or cruise?
- Only where your iPhone has a cellular signal. In airplane mode or mid-ocean with no signal, there’s no internet to share.
- Can I use a hotspot with a travel eSIM?
- Yes. SIMOVO eSIMs include tethering, so you can share your data with a laptop or tablet just as you would with a normal SIM - without the roaming bill.
- Why does my hotspot keep turning off?
- iOS drops the hotspot to standby when no devices are connected, to save battery. It springs back automatically when a device tries to join.
