Hotspot and Tethering

Share your phone's internet connection with your laptop via Wi-Fi hotspot or USB tethering

When there's no Wi-Fi available, you can share your phone's cellular data with your laptop. This is called tethering – your phone becomes a portable Wi-Fi router. It works over Wi-Fi (hotspot), USB cable, or Bluetooth.

A few things to know upfront:

  • Data usage: Hotspot traffic uses your phone's cellular data. Video calls, streaming, and large downloads can burn through gigabytes quickly. Many phone plans include hotspot data, but some throttle speeds or have separate caps for hotspot use. Check your plan
  • Speed: You'll get your phone's cellular speed minus some overhead. Expect 10-50 Mbps on a decent LTE/5G connection, sometimes more. Run a speed test once connected to see what you're actually getting
  • Battery: Running a hotspot drains your phone battery fast. Plug your phone into power if possible, or use USB tethering which charges your phone at the same time

Wi-Fi hotspot:

  1. Open Settings > Personal Hotspot (or Settings > Cellular > Personal Hotspot on some versions)
  2. Toggle Allow Others to Join on
  3. Note the Wi-Fi password shown on screen – you'll need it on your laptop
  4. On your laptop, open Wi-Fi settings and connect to your iPhone's name
  5. Enter the password when prompted

Your iPhone shows a green status bar (or green pill on notched iPhones) when a device is connected to your hotspot.

Instant Hotspot (Apple devices):

If your laptop is a Mac signed into the same Apple Account, you don't need to do anything on your iPhone. Just open the Wi-Fi menu on your Mac and your iPhone appears as an available network. Click it to connect – no password needed.

USB tethering:

  1. Connect your iPhone to your laptop with a Lightning or USB-C cable
  2. If prompted on your phone, tap Trust this computer
  3. On your iPhone, go to Settings > Personal Hotspot and toggle it on
  4. Your laptop should recognize the connection automatically

On Mac, the connection shows up in System Settings > Network. On Windows, you need iTunes installed for the iPhone USB driver – once installed, the connection appears in your network settings.

Troubleshooting:

  • If Personal Hotspot is missing from Settings, your carrier may not support it or it may need to be enabled on your plan. Contact your carrier
  • If devices can see the hotspot but can't connect, try changing the hotspot password in Settings > Personal Hotspot > Wi-Fi Password
  • Restart your iPhone if the hotspot is on but nothing can find it
  • For better range and speed, keep the hotspot device and your laptop in the same room

Frequently Asked Questions

How much data does hotspot use?▾

It depends entirely on what you're doing. Browsing and email use minimal data (a few MB per hour). Video calls use 1-2 GB per hour. Streaming HD video uses 3-5 GB per hour. OS updates can be several gigabytes. If you're on a limited data plan, avoid streaming and large downloads, and check your data usage in your phone's settings.

Is hotspot slower than regular Wi-Fi?▾

Usually yes. You're limited by your cellular connection speed, which varies with signal strength and network congestion. A good 5G connection can match or beat slow home Wi-Fi, but a weak LTE signal might feel painfully slow. USB tethering is typically faster and more stable than Wi-Fi hotspot because there's no wireless overhead.

Can my carrier tell I'm using hotspot?▾

Yes. Carriers can detect hotspot traffic and many plans treat it differently from regular phone data. Some plans include unlimited phone data but cap hotspot data at a lower amount or throttle hotspot speeds. Check your specific plan details.

Why does my hotspot keep disconnecting?▾

On iPhone, the hotspot turns off automatically if no device is connected for a few minutes to save battery. On Android, there's usually an Auto turn off setting you can disable. Also check that your laptop isn't switching to a different Wi-Fi network – Windows and Mac both auto-join saved networks, which can cause your device to jump off the hotspot.

Can I use hotspot for work video calls?▾

Yes, if your cellular signal is decent. Video calls need about 2-5 Mbps upload and download. Run a speed test first to check. Use USB tethering if possible for the most stable connection, and close other apps that might use bandwidth in the background.
