What a hotspot does and when you need one
A hotspot is a way to share your phone's internet connection with other devices — a laptop, tablet, or another phone. Instead of connecting those devices to a Wi-Fi network, they connect directly to your phone, which acts as the middleman between them and your mobile carrier's network.
You need a hotspot when you're away from home or the office and don't have access to Wi-Fi, but you need internet on a device that doesn't have its own cellular connection. A laptop at a coffee shop, a tablet in a car, or a friend's phone on a road trip are common reasons. Your phone uses its own data plan to provide the connection, so you'll be using data from your monthly allowance.
Most phones can create a hotspot without extra apps or subscriptions, though your carrier may charge extra for the feature or count hotspot data differently than regular phone data. Check your plan before you start — some plans include hotspot data, others charge per gigabyte, and some don't allow it at all.
Key Takeaways
- Hotspot is built into both iPhone and Android phones and turns on in Settings without needing extra apps.
- Your phone uses its own data plan when devices connect to your hotspot, so monitor how much data other devices are using.
- You set a password when you turn on hotspot, and other devices need that password to connect — treat it like a Wi-Fi password.
- Battery drains faster when hotspot is on, so plug in your phone or turn off hotspot when you're done.
- Most carriers allow hotspot, but some plans charge extra or limit how much hotspot data you can use each month.
How to turn on hotspot on an iPhone
Open Settings on your iPhone and tap Personal Hotspot. If you don't see it, tap Cellular first, then look for Personal Hotspot below it. Tap the toggle next to Personal Hotspot to turn it on.
When you turn it on for the first time, your phone shows a Wi-Fi password at the top of the screen. Write this down or take a screenshot — you'll need it when other devices connect. You can change the password by tapping Wi-Fi Password and typing a new one. The name that appears to other devices is your iPhone's name, which you can change in Settings > General > About > Name.
Once hotspot is on, the status bar at the top of your screen shows a blue bar with "Personal Hotspot" and the number of connected devices. Other devices will see your iPhone's name in their Wi-Fi list and can connect using the password you set.
How to turn on hotspot on an Android phone
The exact steps vary by manufacturer, but the general path is the same. Open Settings, then look for Network & Internet, Connections, or Wireless (the name depends on your phone). Tap Hotspot or Mobile Hotspot, then tap the toggle to turn it on.
Android shows you a default name and password. The name is usually something like "AndroidAP" or your phone's model name. Tap Set Up Hotspot or Configure to change the name and password to something you'll remember. Make the password at least 8 characters long and use a mix of letters and numbers so it's harder to guess.
Once it's on, other devices will see your hotspot name in their Wi-Fi list. They'll need your password to connect. Your phone's status bar usually shows an icon or notification that hotspot is active.
Connecting devices to your hotspot
On the device you want to connect — a laptop, tablet, or another phone — open the Wi-Fi settings and look for your phone's hotspot name in the list of available networks. Tap or click on it, then enter the password your phone is broadcasting. The device will connect and start using your phone's data.
On a Windows laptop, go to Settings > Network & Internet > Wi-Fi, click Manage Known Networks, and look for your phone's hotspot name. On a Mac, click the Wi-Fi icon in the menu bar and select your phone's hotspot from the list. On an iPad or Android tablet, open Settings > Wi-Fi and tap your phone's hotspot name.
Once a device is connected, you'll see it listed in your phone's hotspot settings. Most phones show how many devices are currently using the connection. If a device isn't connecting, make sure you entered the password correctly — passwords are case-sensitive.
Managing data and battery when using hotspot
Hotspot uses data from your phone's plan, and it can add up quickly if other devices are downloading large files, streaming video, or running updates. A laptop downloading a software update or a tablet streaming video can use several gigabytes in an hour. Check your plan to see how much hotspot data you have, and warn anyone connecting to your hotspot that they should avoid heavy downloads.
You can see how much data is being used by looking at your phone's data usage settings. On iPhone, go to Settings > Cellular > Cellular Data and scroll down to see which apps are using the most data. On Android, go to Settings > Network & Internet > Mobile Network > Data Usage. If you're running low on data, turn off hotspot until your next billing cycle.
Hotspot drains your phone's battery much faster than normal use because your phone is working harder to broadcast a signal and maintain connections. If you're going to use hotspot for more than an hour, plug your phone into a charger. Turn off hotspot when you're done using it — leaving it on in your pocket will drain the battery even if nothing is connected.
Troubleshooting common hotspot problems
If other devices can't see your hotspot, make sure it's actually turned on by checking your phone's settings. If it's on but not showing up, try turning it off and back on again. On some phones, you may need to restart the phone entirely. If your carrier blocks hotspot on your plan, you won't be able to turn it on at all — contact your carrier to check whether hotspot is included.
If a device connects but has no internet, the problem is usually that your phone itself doesn't have a signal or data connection. Check that your phone shows bars of signal and that mobile data is turned on. If your phone has data but the connected device still can't reach the internet, forget the hotspot network on that device and reconnect. On most devices, this means going to Wi-Fi settings, tapping the hotspot name, and selecting "Forget" or "Remove".
If hotspot keeps disconnecting, your phone may be going to sleep or turning off Wi-Fi to save battery. On iPhone, go to Settings > Screen Time > App Limits and make sure nothing is restricting background activity. On Android, check Settings > Battery > Battery Saver and turn it off if it's limiting hotspot. Some phones also disconnect hotspot if no devices are connected for a few minutes — this is normal and saves battery.
Hotspot on different carriers and plans
Most major carriers — Verizon, AT&T, T-Mobile, and others — allow hotspot on their plans, but the details vary. Some plans include unlimited hotspot data, others include a set amount per month (like 10 or 50 GB), and some charge extra. A few older or budget plans don't allow hotspot at all. Check your carrier's website or call customer service to confirm what your plan includes.
If your plan doesn't include hotspot or you've used up your monthly allowance, your carrier may let you buy extra hotspot data as an add-on. Prices vary, but it's usually more expensive than regular data. If you use hotspot regularly, it may be worth upgrading to a plan that includes more hotspot data rather than paying overage charges each month.
Frequently Asked Questions
Does using hotspot cost extra?
It depends on your plan. Some plans include hotspot data at no extra cost, others include a limited amount per month, and some charge extra. Check your carrier's website or your bill to see what your plan covers. If you don't have hotspot included, you may be able to add it for a monthly fee.
Can I use hotspot while on a phone call?
On most modern phones, yes — you can use hotspot while talking on the phone, and the other devices will stay connected. However, if you're using an older phone or on a network that doesn't support simultaneous voice and data, the hotspot may pause while you're on a call.
How many devices can connect to my hotspot at once?
Most phones allow between 5 and 10 devices to connect at the same time, though the exact number depends on your phone model. Even if more devices could technically connect, each additional device slows down the connection for everyone else, so it's best to keep the number low.
Will my hotspot work internationally?
Only if your phone has an international data plan or you've purchased roaming data from your carrier. Hotspot uses your phone's cellular connection, so if you don't have data service in another country, hotspot won't work. Contact your carrier before traveling to see what options are available.
What's the difference between hotspot and tethering?
Hotspot and tethering mean the same thing — sharing your phone's internet connection with other devices. Hotspot is the term Apple uses for iPhones, while Android and some carriers use tethering, but they're the same feature.
