Sharing internet from your iPhone is useful, but calling it “free” is a bit misleading. Let me explain.
Your iPhone has a feature called Personal Hotspot (sometimes it appears as “Share Internet” or “Personal Hotspot”). You turn on the switch in Settings, you set a password, and your phone creates a network Wi-Fi that other devices (another iPhone, a laptop, a tablet) can connect to.
The part that isn’t free: You’re sharing the mobile data from your plan. If your plan isn’t unlimited, it will be used up quickly and you might get a surprise on your bill. Also, some carriers don’t even include this feature in their most basic plans, and they charge you to activate it. It’s not a magic service; it’s your own connection, shared out.
How do you do it? On the iPhone that shares: Settings > Personal Hotspot > Turn on “Allow Others to Join”. You set a secure password. On the receiving device, you look for the Wi-Fi network named after your iPhone and enter that password. If both are Apple devices and use the same ID account, it won’t even ask for a password; they connect on their own.
Things you should know:
- It’s not a repeater: You can’t connect to a public Wi-Fi and then rebroadcast that signal. You only share your mobile data network (4G/5G).
- Battery and coverage: The phone that shares drains much faster and needs a good data signal.
- Limits: There’s usually a limit on connected devices at once (normally about five), and they all need to be close, within about 10 meters.
The “free” app alternatives are questionable. There are apps like WiFi Master that claim to create a community network of shared Wi-Fi. The problem is security. To use those networks, you also have to share yours, exposing your home connection. Plus, those apps tend to collect a lot of personal data. I don’t recommend it.
If it’s just for a one-off emergency (sending an urgent email from your laptop or letting a friend check a map), the iPhone’s Personal Hotspot is a practical solution. If what you’re looking for is truly free and constant internet for several devices, this isn’t it. You’re using, and paying for, your own mobile data.
