What a hotspot is and when you need it
A mobile hotspot is internet access shared from one device — usually a phone or tablet — to other devices nearby. Your phone uses its cellular data plan to create a small wireless network that laptops, tablets, or other phones can join, the same way they would join home WiFi. You are essentially turning your phone into a router.
You need this when you are away from home WiFi and want to use a device that does not have its own cellular connection. A laptop at a coffee shop, a tablet in a car, or a second phone on a trip are common reasons. The hotspot uses your phone's data plan, so you are consuming the same monthly data allowance you would use if you were browsing on the phone itself.
Hotspots are also useful as a backup when your home internet goes down — you can tether a laptop to your phone to keep working while you wait for service to return.
Key Takeaways
- Turn on your phone's hotspot in Settings, find the option labeled Personal Hotspot (iPhone) or Mobile Hotspot (Android), and toggle it on.
- On the device you want to connect, open WiFi settings and select your phone's hotspot name from the available networks list.
- Enter the password your phone displays — this is usually eight characters and shown in the hotspot settings screen.
- Data used on the connected device counts against your phone's monthly data plan, so monitor usage if your plan has limits.
- Turn off the hotspot when you are done to save your phone's battery and prevent accidental data use.
How to turn on hotspot on an iPhone
Open Settings on your iPhone and tap Personal Hotspot. If you do not see this option, your carrier may not support it — contact them to confirm it is included in your plan. Toggle the switch next to Allow Others to Join to the on position. The switch will turn green.
Your phone will now display a hotspot name (usually something like "John's iPhone") and a password. Write down the password or keep this screen open — you will need it on the device you are connecting. The password is case-sensitive, so type it exactly as shown.
If you want to change the hotspot name to something easier to remember, tap Personal Hotspot again and then tap the name field to edit it. Keep the name short and avoid special characters, as some devices have trouble connecting to names with symbols.
How to turn on hotspot on an Android phone
Open Settings and search for "hotspot" — the exact location varies by phone manufacturer, but the search function will find it. Tap Mobile Hotspot or Tethering (some phones use both terms). Toggle the switch next to Mobile Hotspot to turn it on.
Your phone will display a network name and password on this same screen. Write down the password before you move to the other device. If you want to change the network name, tap Configure or Set Up Mobile Hotspot and edit the SSID field.
Some Android phones show a notification at the top of the screen when the hotspot is active. This is normal and confirms the hotspot is running.
Connecting a laptop or tablet to the hotspot
On the device you want to connect, open WiFi settings. You should see your phone's hotspot name in the list of available networks. Tap or click on it. A password prompt will appear.
Type the password your phone displayed when you turned on the hotspot. Make sure you enter it exactly — uppercase and lowercase letters matter. Once you enter the correct password, the device will connect and show a "connected" status next to the hotspot name.
If the password does not work, go back to your phone and double-check the password on the hotspot settings screen. If you entered it wrong, try again. If the device still will not connect after three attempts, turn off the hotspot on your phone, wait ten seconds, and turn it back on.
Checking your connection and data usage
Once connected, open a web browser on the connected device and visit any website to confirm the connection is working. If the page loads, your hotspot is active and passing data through.
Data used on the connected device counts toward your phone's monthly data plan. If you have a limited plan, monitor how much data you are using. Streaming video, downloading files, and video calls use data quickly. Browsing text-based websites and checking email use much less.
On iPhone, you can see how much data each app has used by going to Settings > Cellular and scrolling down. On Android, go to Settings > Network & Internet > Mobile Network and tap Data Usage. These screens show your total usage for the month and which apps are using the most data.
Troubleshooting connection problems
If a device will not connect, the most common cause is an incorrect password. Go back to your phone's hotspot settings and read the password aloud character by character as you type it on the other device. Passwords are case-sensitive, so "A" is different from "a".
If the password is correct but the device still will not connect, restart both devices. Turn off the hotspot on your phone, restart your phone completely, and then turn the hotspot back on. On the other device, turn WiFi off, wait five seconds, and turn it back on. Try connecting again.
If the connection drops after a few minutes, your phone may have gone to sleep. Check your phone's screen — if it is dark, wake it up. Phones sometimes disable the hotspot when the screen is locked to save battery. You can usually change this in hotspot settings by looking for an option like Keep Hotspot On While Locked or Always Allow.
If you see a message that says "Cannot Connect" or "Incorrect Password" after multiple attempts, forget the network on the device you are trying to connect. Go to WiFi settings, find your phone's hotspot name, and select "Forget This Network" or "Remove". Then try connecting again from scratch.
Protecting your hotspot from unwanted connections
Your hotspot password prevents strangers from joining your network, but you should still change the default password if you plan to use the hotspot regularly. A strong password is at least eight characters and includes numbers and letters mixed together.
On iPhone, go to Settings > Personal Hotspot and tap the password field to change it. On Android, go to Settings > Mobile Hotspot > Configure and edit the password field. Write down your new password somewhere safe so you do not forget it.
If you suspect someone has connected to your hotspot without permission, turn off the hotspot, change the password, and turn it back on. This will disconnect anyone who was using it. You can also limit the number of devices that can connect at once — most phones allow between 5 and 10 simultaneous connections by default.
Frequently Asked Questions
Does using a hotspot use more data than browsing on my phone?
No. Data is data — whether you browse on your phone or on a laptop connected to your phone's hotspot, the same amount of data is used. The difference is that on a laptop, you might use data faster because the screen is larger and you might read files or stream video more easily.
Can I use a hotspot if my phone plan does not have unlimited data?
Yes, but you should monitor your usage. Every megabyte used on the connected device counts against your monthly limit. If you have a 5 GB plan and you stream an hour of video on a laptop, you might use 500 MB to 1 GB of that limit in one sitting.
Why does my hotspot keep disconnecting?
The most common cause is that your phone's screen went to sleep. Phones often disable the hotspot when locked to save battery. Check your hotspot settings for an option to keep it on while the screen is off. If that does not work, restart both devices and try again.
Can I connect multiple devices to one hotspot at the same time?
Yes. Most phones allow 5 to 10 devices to connect simultaneously, though the more devices you connect, the slower the connection becomes for each one. Check your phone's hotspot settings to see the maximum number allowed.
What should I do if I forgot my hotspot password?
Go back to your phone's hotspot settings — the password is displayed there. If you changed it and cannot remember the new one, you can reset it by turning off the hotspot, waiting ten seconds, and turning it back on. Your phone will generate a new default password.
