Auto join hotspot is a device setting that lets your iPhone, iPad, Mac, or Android phone automatically connect to a personal hotspot from a nearby device you own or that is approved through Family Sharing, without needing to type the password each time. It simplifies staying online by handling the connection in the background when no Wi‑Fi network is available, so you can focus on using the internet rather than hunting for settings.
What auto join hotspot means on iPhone and Android
On Apple devices, Auto‑Join Hotspot is a setting that lets a nearby device automatically connect to a Personal Hotspot when no Wi‑Fi network is available, or ask before joining, depending on the selected setting. Google’s Android feature is documented as Internet sharing with Instant hotspot and Automatically share Wi‑Fi, which can connect nearby owned devices without password entry after approval. Samsung documents Auto Hotspot connection as choosing when to connect to a nearby Auto Hotspot, and says it only works when Wi‑Fi is on and a nearby Auto Hotspot is available. Samsung Auto Hotspot connection is one of the connection options on Galaxy phones and tablets.
How auto join hotspot works
On Apple devices, the device providing the hotspot must have Personal Hotspot available, and the joining device must be nearby with Wi‑Fi and Bluetooth turned on and signed in with the same Apple Account. Family members can be added through Family Sharing on the hotspot‑hosting device. The joining device can be set to Ask to Join or Automatic on iPhone, iPad, and Apple Vision Pro by going to Settings > Wi‑Fi > Auto‑Join Hotspot. On Apple Watch, the path is Settings > Wi‑Fi > Auto Hotspot Settings. On Mac, open Wi‑Fi Settings from the menu bar and change Ask to join hotspots; the Automatic option is available in macOS Tahoe 26 or later.
On Android, open Settings > Google > All services > Devices & sharing > Cross‑device services, make sure Use cross‑device services is on, then under What your devices can do tap Internet sharing and verify Use internet sharing, Instant hotspot, and/or Automatically share Wi‑Fi are on. Both features are available for Android 11 and up, with more functionality on Android 14 and newer devices. An Android device without internet can search nearby owned devices for a cellular or Wi‑Fi connection, show a notification, and connect automatically with no password entry after approval. Samsung’s Auto Hotspot connection works only when Wi‑Fi is turned on and there is a nearby Auto Hotspot.

Apple’s Family Sharing lets approved family members connect automatically without entering the hotspot password. Google’s Android feature can connect either to a nearby cellular hotspot or to shared Wi‑Fi access automatically after approval. For a deeper look at how these connections work and common fixes, see the section on hotspot basics and troubleshooting (Mobile Hotspot Basics and Troubleshooting).
Limitations of auto join hotspot

The feature behavior changes by setting: Ask to Join prompts the user, while Automatic joins without prompting.

Frequently Asked Questions
Does auto‑join hotspot work without Bluetooth?
No. On Apple devices, Bluetooth must be turned on for the device to detect and negotiate the hotspot connection. Android’s Instant hotspot also uses Bluetooth for discovery, so turning Bluetooth off will prevent automatic connections.
Will auto‑join hotspot use my mobile data automatically?
Yes, when your device connects to a personal hotspot, it uses the hotspot host’s cellular data plan. On Android, the feature can also share a Wi‑Fi connection, but if the host is using cellular data, that data will be consumed.
How do I stop a device from auto‑joining a hotspot?
On iPhone, iPad, or Mac, change the Auto‑Join Hotspot setting to Ask to Join or Off. On Android, turn off Instant hotspot or Automatically share Wi‑Fi in the Internet sharing settings. On Samsung, turn off Auto Hotspot connection.
Can I use auto‑join hotspot with a device that isn’t mine?
Apple’s feature works only with devices signed into the same Apple Account or approved through Family Sharing. Android’s feature works only with devices signed into the same Google Account after initial approval. You cannot auto‑join a stranger’s hotspot without entering a password.
Does auto‑join hotspot drain the battery?
The feature itself uses minimal power because it relies on Bluetooth Low Energy for discovery. However, once connected, using the hotspot for data will consume battery on both the host and the joining device.
