It is hard to consider of the use of hotspot until you find Ethernet unavailable. Yet once it happens to you, you may appreciate so much the function of hotspot. Since people are likely to carry laptops and iPad when in business journey, finding a way to share your iPhone’s cellular connection with Wi-Fi-only devices nearby seems useful.
How to set up an iPhone Wi-Fi hotspot
Firstly, open the Settings app and then select Mobile Data. (In some older versions of iOS you can select Mobile.)
Secondly, tap Personal Hotspot, and set Personal Hotspot to on.
Be care that when Wi-Fi and/or Bluetooth are off, iOS will ask if you want to turn them back on. For the consideration of security, it is not advisable to do so.
Thirdly, tap ‘Wi-Fi Password’ and enter a suitable password.
Fourthly, check the name of the hotspot listed under To Connect Using Wi-Fi.
After these procedures, you can simply connect it to your laptop or other smartphones by clicking the Wi-Fi icon in your device’s Menu bar, or taping Wi-Fi on and choosing the Wi-Fi hotspot. With the right input of password you can use the hotspot at your disposal.
What if someone tries to hijack the connection?
Since the hotspot is visible to every device nearby, it is possible for others connect to your devices in special way. Once it happens, your data flow will be largely consumed and may even cause big expenses. However, the only solution of it is to set up a more complicated password and care about the notification of your cell phone. You’ll see a small notification at the top of your iPhone’s screen when a device accesses its hotspot, so you’ll get a warning if someone in your train carriage does manage to guess your password. Furthermore, a more important warning concerns data limits on your own surfing. Keep in mind that data consumed quickly when browsing the website and downloading. Thus, it is suggestible to avoid downloading large apps.

Besides the basic information for using the hotspot, it is still necessary for you to dig out some related problems. First of all, not every cellular carrier includes hotspot feature in every plan. In this case, you may have to pay extra to gain access to it. In addition, it’s important to remember that when you use your iPhone as a data connection, you are using your mobile data plan and if you have a data cap, it will count towards that. Last but not least, Wi-Fi tethering will also drain your phone’s battery more quickly. For longer use of your cell phone, you should connect your iPhone to a power bank or plug it into your laptop via USB cable while tethering.
