Android: how to share the 4G internet connection of the smartphone

Sharing an internet connection from an Android smartphone is both simple and practical. This allows you to use the data from your mobile plan on your tablet or computer. In this tutorial, we will take it step by step so that you can configure internet connection sharing from your smartphone to another device in a jiffy.

A very practical option on Android, connection sharing allows you to transform your smartphone into a modem or a hotspot . Your computer or tablet will then be able to use the data plan of your smartphone to connect to the internet, provided you have a sufficient data plan.

Connection sharing on Android: how does it work?

Android like iOS allows you to easily transform your smartphone into a WiFi, Bluetooth and USB router. We can then use 3G / 4G mobile data as an internet connection and share it with the devices of your choice. WiFi, Bluetooth, USB… each connection mode has its particularities, advantages and disadvantages which should be taken into account depending on the situation.

When  sharing a connection via WiFi,  your smartphone creates an ad hoc wireless network for which you can choose the name and password. Other devices connect to it like any other wireless router. The advantage of this connection mode is its simplicity. The downside is that you can’t really control what connects to it. This can lead to excessive data consumption.

The Bluetooth tethering  is based on the specifics of this technology. The range of the Bluetooth signal is relatively short, which limits the risk of unwanted connections. To connect to your Bluetooth network, you must also pair the devices. In general, only one device can be connected via Bluetooth.

The  tethering via USB changes the behavior of C-USB port on your smartphone. So when you connect your smartphone to your computer, the latter detects a new network card and installs drivers – at least during the first connection. Once the configuration is done, the connection can be established. This method is the most secure, since it is impossible to connect via USB without your knowledge – and the fact that there is no wireless network limits the risk of hacking.

Note : connection sharing via USB is only compatible with Windows and Linux PCs.

How to do connection sharing on Android


To do this, check beforehand that the airplane mode is inactive and the data is activated. The following steps are very simple:

  • Go to  Settings
  • Go to More> Connection Sharing , Network and Internet> Access Point and Connection Sharing , or similar, the aim being to find a menu with the words Connection Sharing in the settings

What happens next depends on whether you want to share your smartphone’s internet connection via WiFi, Bluetooth or USB.


  • Tap WiFi hotspot
  • Tap if necessary  Configure the Wi-Fi access point to choose the access point name, password and security

Note : even if the interface allows it, it is strongly advised not to choose None  for the security of the key. Just like at home, choose something more or less secure like WPA2 TKIP-AES. And a sufficiently complex key, especially in public places.

  • Activate the WiFi access point


  • Activate Bluetooth Connection Sharing


  • Activate  Connection Sharing via USB

Connection sharing: how to limit the impact on autonomy?

Sharing your internet connection from a smartphone consumes a lot of battery. Some smartphones can limit this by automatically disabling the access point when no device is connected to it. In the other cases, to keep a little autonomy:

  • Recharge your smartphone as soon as possible from the mains or external battery
  • Manually deactivate connection sharing when it is no longer necessary
