A 3G modem uses a 3G network to establish an Internet connection. It is ideal for travellers and other people who are always on the go. It is also a popular choice for those whose computers do not have a wireless card installed. A 3G modem usually comes as a USB plug or a dongle with a SIM card placed inside that can easily be connected to the computer. The Internet connection speed delivered by a 3G modem is dependent on the strength of the network signal, the speed of the computer you are using and many other factors.

Moderately Easy


  1. 1

    Ensure that the 3G modem specifications conform to the actual speed of the 3G network you are subscribed to. For instance, your 3G Internet dongle may only have a 3.6MB capacity while the 3G network has a speed of 7MB. If this is the case, you will need to replace the dongle for a faster Internet connection.

  2. 2

    Close applications such as games and media players that may slow down the speed of the 3G connection. If you do not notice any improvement on the 3G connection speed, reboot the computer.

  3. 3

    Ensure that the SIM card is properly attached to the 3G modem. Disconnect the 3G modem from the computer and place the SIM card properly into its slot. Connect the 3G modem again and see if it generates significant results.

  4. 4

    Move the computer near a window or door to get a stronger signal. If you are in an enclosed area, you may receive a weaker 3G signal as compared to when you are in an open area.

  5. 5

    Disconnect the 3G modem and reconnect it to the computer. This should refresh the connection and boost the 3G modem signal. Reboot the computer.

Tips and warnings

  • It is normal for the Internet connection to slow down during peak hours because of the number of users sharing the 3G network. "Peak hours" are the period of the day when the demand for Internet access is at its highest. The specific hours may vary depending on the service provider you are subscribed to. For a faster Internet connection, try using your 3G modem during off-peak hours.
