The Samsung Galaxy Buds Pro has two selectable active noise canceling settings: low and high. Both settings work quite well considering it is a pair of true wireless earbuds. If you want to attenuate more low-end noise, such as airplane rumbles or the sound of your dishwasher, you should go with the high setting. On the other hand, if you want to block out more mid-range noise, such as people talking, go with the low setting, though it won’t completely cancel out human speech.

Create the wvdial config file

• The next step is to create a config file for wvdial so you can connect to your service provider.
• Open a terminal window and enter:

sudo leafpad /etc/wvdial.conf

• Replace the content of the file with the following.

[Dialer 3gconnect]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Init3 = AT+CGDCONT=1,"IP","internet"
Stupid Mode = 1
Modem Type = Analog Modem
ISDN = 0
Phone = *99#
Modem = /dev/gsmmodem
Username = { }
Password = { }
Baud = 460800

• Replace internet with your service provider’s APN
• Replace the Phone number if you need to dial a different code to connect.
• Replace Username and Password if needed. To leave the username and password as blank use { }
