Even though the most popular services like Facebook or Gmail are encrypted, using public Wi-Fi networks isn’t very secure and I wouldn’t recommend it to anyone.
It’s best to have your own Wi-Fi hotspot and be totally independent in this respect.
If you have some mobile data plan (at least a few GB per month), you can easily turn your Android phone into a Wi-Fi hotspot. In this short tutorial I will show you how to do it step by step and tell you why it’s a good idea.
If you need to be online (whether while you are travelling or when you are at work), you should only use “your own” Internet.
These are just a few reasons why you should turn your Android phone into a Wi-Fi hotspot instead of connecting to a public network (or the network at your work):
These are the tree reasons why it’s a good idea, but now let’s explore a few disadvantages of this solution.
Turning your Android phone into a Wi-Fi hotspot is the best you can do if you want to have access to the mobile Internet.
However, there are a few cons you should also know about. Here is what you need to know:
Here is how you make your Android phone a hotspot:
If your mobile data is working correctly, you will see either LTE, H or E near the signal strength bar.
You can also enable mobile data if you go to Settings > Data usage. Make sure that Mobile data traffic is turned on.
The next step is to turn on the mobile hotspot functionality. Go to Settings > More and then choose Tethering & portable hotspot.
Make sure Portable Wi-Fi hotspot is turned on. Next click on Portable Wi-Fi hotspot settings to configure it.
When in Portable hotspot settings, choose Configure Wi-Fi hotspot. Make sure security is not set to None but to WPA2 PSK. Create a unique and strong password (of at least 10 characters, upper and lower case letter, numbers and special characters like #$%@).
When Wi-Fi hotspot is enabled in your device you will see its icon in the top bar.
That’s all. You have just successfully turned your Android phone into a Wi-Fi hotspot.
