Setting up and using a personal hotspot on your iPhone is a handy way to share your cellular data connection with other devices like laptops, tablets, or another phone. Here’s how to do it step by step.

1. Turn on Personal Hotspot on iPhone

Before you can share your connection, you need to enable the hotspot feature:

1. Open the Settings app.
2. Tap Personal Hotspot (if you don’t see it, go to Settings > Cellular > Personal Hotspot).
3. Toggle on Allow Others to Join.

If this is your first time using it, you may need to set a Wi-Fi password and choose a network name (which defaults to your iPhone name).

2. Connect Other Devices to Your iPhone Hotspot

You can share your connection in three ways:

Via Wi-Fi (Recommended for most devices)

• On the device you want to connect (like a laptop), go to Wi-Fi settings.
• Look for your iPhone’s network name (e.g., “John’s iPhone”).
• Select it and enter the Wi-Fi password shown in the Personal Hotspot settings.
• Tap Join.

Via Bluetooth

• Pair your iPhone with the other device via Bluetooth first.
• Once paired, go to Settings > Personal Hotspot and make sure it’s on.
• On the other device, choose to connect to the internet via the iPhone through Bluetooth (this option appears after pairing).

Via USB (Best for speed and charging)

• Connect your iPhone to a computer using a Lightning or USB-C cable.
• Unlock your iPhone and tap Trust if prompted.
• The computer should automatically detect the hotspot and use it for internet access (may require driver setup on Windows).

3. Manage Hotspot Settings and Security

• Change Wi-Fi Password: In Personal Hotspot, tap Wi-Fi Password to update it.
• Change Network Name: Go to Settings > General > About > Name to change your iPhone’s name, which also changes the hotspot name.
• Limit Data Usage: Since hotspot uses cellular data, keep an eye on usage under Settings > Cellular > Personal Hotspot to avoid overages.
• Turn Off When Done: Always disable the hotspot when not in use to save battery and prevent unauthorized access.

Troubleshooting Tips

• Can’t find the hotspot? Restart both devices and ensure hotspot is enabled.
• Connected but no internet? Check your iPhone’s cellular signal and data plan.
• Devices won’t connect? Forget the network on the device and reconnect, or reset network settings on iPhone (Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings).

Using your iPhone as a hotspot is simple once set up. Just remember it drains battery and uses data quickly — so keep your charger handy and monitor usage.基本上就這些。
