What a personal hotspot does and why you'd use it
Your iPhone's personal hotspot turns your phone into a portable Wi-Fi router. When you enable it, other devices — a laptop, tablet, or another phone — can connect to the internet through your iPhone's cellular data instead of needing their own connection. This is useful when you're away from home Wi-Fi and need to work on a computer, or when someone near you needs internet access.
The hotspot uses your phone's data plan. Whatever data limit your phone has, the hotspot shares that same pool. If you have unlimited data, your hotspot can run without worrying about overage charges, but your phone company may still slow your speeds after a certain amount of use in a month.
Before you start, check two things: your phone plan includes hotspot access (most do, but some budget plans don't), and you have cellular signal where you are. A hotspot won't work if your phone has no bars.
Key Takeaways
- Personal hotspot is found in Settings under Cellular, and you turn it on with a single toggle switch.
- Other devices see your hotspot as a Wi-Fi network and connect using a password your iPhone generates automatically.
- You can connect up to five devices at once on most plans, though your data will be split among them.
- If another device won't connect, restart both the iPhone and the device trying to join, then try again.
Turning on personal hotspot on your iPhone
Open Settings on your iPhone. Tap Cellular, then scroll down and tap Personal Hotspot. You'll see a toggle switch at the top — tap it to turn the hotspot on. The switch will turn green and show "On".
Your iPhone will now broadcast a Wi-Fi network. The network name (called the SSID) is usually something like "Marcus's iPhone" — whatever you named your phone when you set it up. Write down or remember this name, because other devices will need to find it in their Wi-Fi list.
Below the toggle, you'll see a password. This is the security code other devices need to type in to connect. The password is generated automatically and is usually something like "abc12345def". You don't need to change it unless you want to — the default is find enough.
Connecting another device to your iPhone's hotspot
On the device you want to connect (a Mac, Windows laptop, iPad, or another iPhone), open the Wi-Fi settings. Look for your iPhone's network name in the list of available networks. Tap or click on it.
When prompted, type the password from your iPhone's Personal Hotspot screen. Make sure you type it exactly — passwords are case-sensitive, meaning capital letters matter. Once you enter the password correctly, the device will connect and show a connected status.
On your iPhone, the Personal Hotspot screen will show how many devices are connected and how much data they've used. If you connect a device and it doesn't show up there after a few seconds, the connection didn't work — try entering the password again.
Troubleshooting when a device won't connect
If a device keeps rejecting the password even though you've typed it correctly, restart both devices. Turn off your iPhone completely, wait ten seconds, and turn it back on. Do the same with the device trying to connect. Then try connecting again.
If the network name doesn't appear in the Wi-Fi list at all, make sure Personal Hotspot is actually turned on — go back to Settings and check that the toggle is green. Also make sure your iPhone has cellular signal (check for bars at the top of the screen). If you're in an area with no signal, the hotspot won't broadcast.
If the device connects but has no internet, check that your iPhone itself has internet. Open Safari or another app on your phone and load a website. If your phone has no internet either, the hotspot can't provide it. Wait for signal to return or move to a location with better coverage.
How many devices can connect at once
Most phone plans allow up to five devices connected to your hotspot simultaneously. However, the more devices you connect, the slower the internet will be for each one, because they're all sharing your phone's single cellular connection.
If you try to connect a sixth device, it will fail to connect. You'll need to disconnect one of the existing devices first. On the device you want to remove, go to Wi-Fi settings and tap "Forget This Network", or straightforward turn off Wi-Fi on that device.
Turning off the hotspot when you're done
Go back to Settings, tap Cellular, then tap Personal Hotspot. Toggle the switch to off — it will turn gray. Your iPhone will stop broadcasting the network, and any devices currently connected will lose internet access through the hotspot.
Turning off the hotspot when you're not using it saves battery life on your iPhone. The hotspot uses more power than normal because your phone is actively transmitting a Wi-Fi signal. If you're on battery and not actively using the hotspot, switching it off will extend how long your phone lasts.
Why your hotspot might be slow
Hotspot speed depends on the cellular signal your iPhone receives. If you're in a location with weak signal (one or two bars), the hotspot will be slow. Move closer to a window or to higher ground if possible.
Speed also drops when multiple devices are connected. If you have three laptops and two tablets all using the hotspot at once, each one gets a smaller share of the bandwidth. Disconnect devices you're not actively using.
Your phone company may also throttle (slow down) hotspot speeds after you've used a certain amount of data in a month, even if you have an unlimited plan. Check your plan's terms to see if this applies to you. If you regularly need fast, unlimited hotspot access, you may want to look into a plan that prioritizes hotspot data.
Frequently Asked Questions
Does using hotspot cost extra money?
No extra charge — the hotspot uses data from your existing phone plan. If you have a limited data plan, the hotspot counts against that limit. If you have unlimited data, the hotspot is unlimited too, though your phone company may slow speeds after very high usage in a month.
Can I use hotspot while I'm on a phone call?
Yes. You can talk on the phone and have other devices connected to your hotspot at the same time. However, your data speeds may be slower during an active call on some networks.
What if my phone plan doesn't include hotspot?
Contact your phone company and ask if you can add hotspot to your plan. Many carriers offer it as an add-on for a monthly fee, or you may be able to switch to a plan that includes it. Some budget plans don't offer hotspot at all, so you may need to change plans entirely.
Can I change the hotspot password to something easier to remember?
Yes. In Settings under Personal Hotspot, tap "Wi-Fi Password" and type a new one. Make it at least eight characters long and include numbers or symbols for security. Any devices currently connected will stay connected, but new devices will need the new password.
Why does my hotspot keep turning off by itself?
Your iPhone may have Low Power Mode enabled, which automatically disables hotspot to save battery. Go to Settings, tap Battery, and turn off Low Power Mode. Also check that no other device has disconnected and reconnected — sometimes a device dropping the connection looks like the hotspot turned off.
