A hotspot is a feature on your phone that shares its cellular data connection with other devices over Wi‑Fi, Bluetooth, or a cable. This lets you get online with a laptop, tablet, or another phone when there is no Wi‑Fi network available, turning your phone into a temporary, portable internet source.
What is a hotspot on your phone?
On a smartphone, a hotspot is a built-in feature that shares your phone’s cellular data connection with other devices. Apple calls this Personal Hotspot on iPhone and iPad (Wi‑Fi + Cellular) with an activated carrier plan that includes Personal Hotspot service, while Google documents the same capability as Hotspot and tethering on Android. This feature creates a temporary, portable Wi‑Fi network that other devices can join, allowing them to browse the web, stream video, or check email using your phone’s data plan. It is not a public Wi‑Fi network; it is a private connection you control.
How a phone hotspot works
When you turn on the hotspot, your phone uses its cellular data connection to create a small Wi‑Fi network that other devices can detect and connect to. iPhone sharing methods Apple documents are Wi‑Fi, Bluetooth, and cable. For Apple’s Instant Hotspot, devices must be within 30 feet (10 meters) of each other, and both need Wi‑Fi and Bluetooth turned on. Apple documents Instant Hotspot works when the other device does not have internet access from a Wi‑Fi network. It is important to know that a phone hotspot cannot share a Wi‑Fi network; it shares only the phone’s own cellular internet connection. The hotspot is temporary and portable, so it disappears when you turn it off or move out of range.
How to turn on your hotspot
On iPhone
- Open Settings.
- Tap Cellular, then tap Set Up Personal Hotspot. If Personal Hotspot already appears in Settings, you can tap it directly.
- If Personal Hotspot is dimmed or unavailable, go to Settings > Cellular and make sure Cellular Data is turned on.
On Android
- Open Quick Settings (swipe down from the top of the screen).
- Tap Hotspot. If you do not see the Hotspot tile, tap Edit at the bottom left, then drag Hotspot into your Quick Settings.
- On Pixel phones, you can also go to Settings > Network & internet > Hotspot & tethering > Wi‑Fi hotspot. Google's Android hotspot help applies to Android devices generally, and its cross-device services help page documents the path Google > Devices & sharing > Cross-device services for related features.
Troubleshooting common hotspot problems
If the Personal Hotspot option on iPhone is dimmed, first check that Cellular Data is on in Settings > Cellular. Apple says Personal Hotspot can be unavailable if the wireless carrier has not enabled it or the plan does not support it. If other devices cannot connect, open Settings > Personal Hotspot and turn on Allow Others to Join. On iPhone 12 or later, iPad Pro 11-inch (3rd generation or later), iPad Pro 12.9-inch (5th generation or later), and iPad mini (6th generation), you can use Maximize Compatibility if connection problems continue. Apple documents Maximize Compatibility on supported models if connection problems continue. For a complete reference on hotspot basics and troubleshooting, check your device’s support documentation. If you are looking for a WiFi hotspot in a car, that is a different type of device, built into the vehicle or added as a separate unit, that uses its own cellular data connection rather than your phone’s.
Frequently Asked Questions
Can I use my smartphone as a hotspot?
Yes, most smartphones can act as a hotspot. On iPhone, this is called Personal Hotspot; on Android, it is called Hotspot or tethering. Both share the phone’s cellular data with other devices over Wi‑Fi, Bluetooth, or a cable.
Does using a hotspot use my data?
Yes. Any data used by devices connected to your hotspot counts against your cellular data plan. If you have a limited data plan, streaming video or downloading large files can quickly use up your allowance.
What devices can connect to my phone hotspot?
Any device with Wi‑Fi, Bluetooth, or a USB cable can connect, laptops, tablets, other phones, gaming consoles, and more. There is no specific device limit documented by Apple or Google for the basic hotspot feature, though carrier restrictions may apply.
Why is my Personal Hotspot option missing or grayed out on iPhone?
This usually means your wireless carrier has not enabled Personal Hotspot on your plan, or your plan does not support it. First, make sure Cellular Data is turned on in Settings. If it still does not appear, contact your carrier to confirm your plan includes hotspot service.
Can I use my phone hotspot while it is connected to Wi‑Fi?
No. A phone hotspot shares only the phone’s cellular data connection. If your phone is already connected to a Wi‑Fi network, it cannot share that same Wi‑Fi connection with other devices through the hotspot feature.
