What Personal Hotspot Does and How to Turn It On
Personal Hotspot lets your iPhone share its cellular data with other devices — a laptop, tablet, another phone, or a smartwatch. When you turn it on, your iPhone becomes a small wireless router. Other devices connect to it the same way they would connect to any Wi-Fi network, and they use your phone's data plan to browse, stream, or read.
To turn on Personal Hotspot, open Settings on your iPhone, then tap General. Scroll down and tap Personal Hotspot. Toggle the switch to On. Your iPhone will show a blue bar at the top of the screen when the hotspot is active and at least one device is connected.
The first time you turn on Personal Hotspot, your iPhone generates a password automatically. You will see this password on the Personal Hotspot settings screen — write it down or remember it, because other devices will need it to connect. You can change this password anytime by tapping Wi-Fi Password in the Personal Hotspot settings.
Key Takeaways
- Personal Hotspot is found in Settings > General > Personal Hotspot and shares your iPhone's cellular data with nearby devices.
- Your iPhone creates a Wi-Fi network name (called an SSID) and a password that other devices use to connect, both visible in the Personal Hotspot settings screen.
- You can connect up to five devices at once on most iPhones, though the actual number depends on your carrier and iPhone model.
- Data used through Personal Hotspot counts against your monthly data plan, so monitor usage if you have a limited plan.
- Battery drains faster when Personal Hotspot is on, especially if multiple devices are connected and actively using data.
Finding Your Network Name and Password
When you turn on Personal Hotspot, your iPhone automatically creates a Wi-Fi network. The network name (technically called an SSID) is usually your iPhone's name followed by a number — for example, "Marcus's iPhone" or "iPhone 14 Pro". You can see this name in the Personal Hotspot settings screen under Wi-Fi Password.
The password appears directly below the network name in the same settings screen. This is the password other devices will type in when they connect. If you want to change either the network name or the password, you cannot do it directly in Personal Hotspot settings — you have to change your iPhone's name in Settings > General > About > Name. The network name will update automatically. To change only the password, tap Wi-Fi Password in Personal Hotspot settings and enter a new one.
Connecting a Device to Your iPhone's Hotspot
On the device you want to connect (a laptop, tablet, or another phone), open the Wi-Fi settings. You will see a list of available networks. Find your iPhone's network name in that list and tap it. When prompted, enter the password from your iPhone's Personal Hotspot settings screen. The device will connect within a few seconds.
Once connected, that device will use your iPhone's cellular data for internet access. You will see a small icon or indicator on the connected device showing it is using a hotspot connection rather than a regular Wi-Fi network. On an iPhone or iPad, this appears as a blue bar at the top showing "Personal Hotspot" or the name of the connected iPhone.
If a device does not connect, check three things: the password is typed correctly (it is case-sensitive), your iPhone's Personal Hotspot is still turned on, and the device is within range (usually 30 to 50 feet for most iPhones). If the device still will not connect, turn Personal Hotspot off and back on, then try again.
Understanding Data Usage and Plan Limits
Every byte of data used through Personal Hotspot counts against your monthly data plan. If you have a plan with 10 gigabytes per month, and you use 2 gigabytes through Personal Hotspot, you have 8 gigabytes left for your iPhone itself. There is no separate data bucket for hotspot — it all comes from the same pool.
Some carriers charge extra for Personal Hotspot or require you to add it as a feature to your plan. Check your carrier's website or call their customer service to confirm whether Personal Hotspot is included in your plan and whether there are any restrictions on how much data you can use this way. A few carriers limit hotspot speeds after you reach a certain amount of data in a month, even if you have data remaining.
To see how much data you have used, go to Settings > Cellular and scroll down to Cellular Data. The total shown includes both data used on your iPhone and data used through Personal Hotspot. You cannot see a separate breakdown in the Settings app, but your carrier's app or website usually shows hotspot usage separately.
Why Your iPhone Gets Hot and Battery Drains Faster
When Personal Hotspot is on and devices are actively using it, your iPhone works harder than normal. The cellular radio, the Wi-Fi radio, and the processor all run at higher power. This generates heat and drains the battery much faster than normal use — expect battery to drop 10 to 20 percent per hour depending on how many devices are connected and how much data they are using.
If your iPhone feels warm to the touch while running Personal Hotspot, that is normal. If it gets very hot or you see a warning that your iPhone is too warm, turn off Personal Hotspot and let it cool down for a few minutes. This is especially common if you are using Personal Hotspot in direct sunlight or in a hot environment.
To reduce battery drain, keep Personal Hotspot off when you are not actively using it. If you are sharing data with multiple devices, consider connecting only the devices that actually need internet right now. Closing apps on connected devices that are running in the background also helps — they use data and drain your battery even when you are not looking at them.
Connecting Multiple Devices and Troubleshooting
Most iPhones allow up to five devices to connect to Personal Hotspot at the same time. Some older models or certain carriers may limit this to fewer devices. If you try to connect a sixth device and it fails, disconnect one of the others first.
If a device was previously connected but will not connect now, try these steps in order: turn Personal Hotspot off and back on on your iPhone, forget the network on the connected device (go to Wi-Fi settings, tap the network name, and select "Forget"), then reconnect by selecting the network again and entering the password. If the device still will not connect, restart both the iPhone and the device you are trying to connect.
If Personal Hotspot is on but no devices can see the network at all, check that your iPhone has cellular signal — you need at least one or two bars. If signal is fine, restart your iPhone. If the network still does not appear, turn off Personal Hotspot, wait 10 seconds, and turn it back on. This usually fixes the issue.
Frequently Asked Questions
Can I use Personal Hotspot if I do not have unlimited data?
Yes, but hotspot data counts against your monthly limit. If you have a 5-gigabyte plan and use 2 gigabytes through hotspot, you have 3 gigabytes left. Check your plan's data limit and monitor usage in Settings > Cellular to avoid overage charges.
Why does my iPhone say Personal Hotspot is on but devices cannot find the network?
Your iPhone may not have cellular signal, or the Wi-Fi radio may need to be reset. Check that you have at least one bar of signal. If signal is fine, turn Personal Hotspot off, wait 10 seconds, and turn it back on. If that does not work, restart your iPhone.
Does Personal Hotspot work on older iPhones?
Personal Hotspot is available on iPhone 4 and newer. If you have an older model, you cannot use this feature. Check your iPhone model in Settings > General > About if you are unsure.
Can I change the network name to something other than my iPhone's name?
Not directly through Personal Hotspot settings. The network name is tied to your iPhone's device name. To change it, go to Settings > General > About > Name and edit the name there. The hotspot network name will update automatically.
What happens to my hotspot if I lose cellular signal?
Personal Hotspot stops working when ready. Connected devices will lose internet access. When you regain signal, the hotspot will work again, but devices may need to reconnect.
