Can you use your eSIM as a hotspot? Yes, if your device and plan support tethering. Learn how to share your eSIM data with a laptop, tablet, or another phone, how to fix common hotspot problems, and how to manage data usage while travelling.
You land, your travel eSIM connects, and you’re online before you’ve reached baggage claim. Then your travel companion needs internet, or your laptop needs a connection when Wi-Fi isn’t available. That’s where an eSIM hotspot comes in.
Your phone can share its mobile data connection with other devices, just as it would with a physical SIM. You only need to check that your plan supports hotspot sharing and enable the correct settings.
Does an eSIM hotspot use your data plan?
Yes. A hotspot shares the data allowance included with your eSIM. There is no separate data allowance just for tethering.
Every connected device uses data from the same plan. For example, browsing on your phone while a laptop downloads files and another phone streams video can use your allowance much faster than using your phone alone.
If you plan to work remotely, join video calls, or connect multiple devices, consider choosing a plan with enough data for all your activities.
Can you use any eSIM as a hotspot?
Not every eSIM plan supports tethering. Availability depends on the provider, the specific plan, and your device.
Before purchasing a travel eSIM:
- Check the plan details for hotspot or tethering support.
- Confirm that your phone is eSIM-compatible and unlocked.
- Check any applicable hotspot limits or fair-use conditions.
- Contact customer support if the plan details are unclear.
Airhub supports hotspot sharing on compatible devices, with no extra hotspot fee. Shared data comes from your existing allowance, so check your chosen plan’s details before purchasing.
How to turn on an eSIM hotspot
Before starting, make sure your eSIM is installed, switched on, and selected as your mobile data line. If you’re travelling internationally, enable data roaming for the travel eSIM when its setup instructions require it.
You can check your device using the Airhub eSIM compatibility guide and follow the eSIM installation guide if you need help setting it up.
How to set up an eSIM hotspot on iPhone
The exact menu labels can vary slightly by iOS version and region.
- Open Settings.
- Tap Cellular or Mobile Data.
- Check that your travel eSIM is selected for cellular data.
- Return to Settings and tap Personal Hotspot.
- Turn on Allow Others to Join.
- Set a strong Wi-Fi password if needed.
- On your laptop, tablet, or other phone, open Wi-Fi settings and select your iPhone’s hotspot name.
- Enter the password to connect.
If Personal Hotspot is missing or unavailable, check that mobile data is working on the eSIM first. You may also need to review your network settings or contact your provider.
How to set up an eSIM hotspot on Android
Android menu names vary between manufacturers. Samsung devices commonly use Connections, while Google Pixel devices use Network & Internet.
- Open Settings.
- Tap Connections or Network & Internet.
- Open Hotspot & Tethering or Mobile Hotspot.
- Check that your travel eSIM is selected as the mobile data line.
- Open the Wi-Fi hotspot settings.
- Set a network name and a strong password.

If your phone uses two SIMs, confirm that the travel eSIM is providing the mobile data connection you want to share.
Can you use USB or Bluetooth tethering?
Yes, if your phone and the device you’re connecting support the feature.
- USB tethering: Connect your phone to a laptop with a compatible cable. This can provide a stable connection and may charge your phone while you work.
- Bluetooth tethering: Connect compatible devices over Bluetooth. It can use less battery for light tasks, but speeds are generally lower than Wi-Fi tethering.
Both methods use the same mobile data allowance as your Wi-Fi hotspot.
eSIM hotspot not working? Try these fixes
If your hotspot won’t connect, work through these checks in order.
1. Check your active data line
If your phone is using your home SIM for mobile data instead of your travel eSIM, switch the data line to the eSIM you intend to use.
2. Confirm that the eSIM has a working connection
Turn off Wi-Fi on your phone temporarily and check whether mobile data works. Confirm that your plan is active and that you haven’t used up its allowance.
3. Check data roaming
Many travel eSIMs require data roaming to connect to partner networks abroad. Enable it for the travel eSIM if instructed by your provider. To avoid unexpected charges, review your home SIM’s data and roaming settings too.
4. Restart the connection
Turn the hotspot off, wait a few seconds, and turn it back on. You can also toggle airplane mode or restart your phone to reconnect to the mobile network.
5. Check the hotspot password
Make sure the connected device is using the correct password. If necessary, forget the saved Wi-Fi network on that device and reconnect.
6. Review network settings
If mobile data works but the hotspot does not, check your provider’s APN instructions and confirm that tethering is supported by your plan. Avoid changing APN settings unless your provider recommends it.
7. Contact support
If the hotspot still won’t work, contact your eSIM provider for help with plan restrictions, activation, or network settings.
How much data does an eSIM hotspot use?
Hotspot data consumption depends on what connected devices do. Browsing and messaging usually use less data than video calls, streaming, or large downloads.
These are rough estimates, not guaranteed usage figures:
| Activity | Approximate data use |
| Web browsing and email | 50–150 MB per hour |
| Music streaming | 50–150 MB per hour |
| Video calls | 0.5–1.5 GB per hour |
| Standard-definition video streaming | Around 0.7 GB per hour |
| HD video streaming | 2–3 GB per hour |
| Laptop or app updates | 2–5 GB per update |
Actual usage varies with video quality, application settings, network conditions, and file size.
Tips to save data while tethering
- Pause automatic software updates and cloud backups on connected laptops and tablets.
- Reduce video quality when streaming.
- Limit background data usage on connected devices.
- Monitor data usage through your phone settings or provider app, where available.
- Disconnect devices when they no longer need internet access.
- Choose a plan with enough data for the number of devices you expect to connect.
A hotspot also uses your phone’s battery. If you plan to share data for a long time, keep a charger or power bank nearby.
eSIM hotspot vs. pocket Wi-Fi vs. public Wi-Fi
Each option suits different travel needs.
| Feature | eSIM hotspot | Pocket Wi-Fi | Public Wi-Fi |
| Extra device to carry | No | Yes | No |
| Setup | Enable hotspot on your phone | Usually rent or buy a device | Connect to an available network |
| Internet source | Your mobile data plan | The device’s mobile connection | The available Wi-Fi network |
| Battery use | Uses your phone battery | Uses its own battery | Uses your device battery |
| Best for | Sharing data with a few devices | Groups or heavier shared use | Occasional access where available |
An eSIM hotspot is convenient because you can share your phone’s connection without carrying a separate router. Pocket Wi-Fi may suit groups that need a dedicated device, while public Wi-Fi can be useful when available.
When using public Wi-Fi, avoid sensitive activities on networks you don’t trust. For private hotspot connections, set a strong password and switch off sharing when you’re finished.
