In this guide, we will explore two methods to resolve this issue and enable users to make voice calls successfully.

💡 Why You Are Getting This Error

  • The primary cause of the 'minicom dialing out error' is that minicom is using the data connection on the phone to establish a voice call, which may not be compatible with the user's minutes plan. This can lead to a 'NO CARRIER' output when attempting to make a call.
  • An alternative reason for this issue could be related to the Huawei e220 device's configuration or the AT&T SIM card settings. However, this is less likely and may require further investigation.

✅ Best Solutions to Fix It

Using minicom with the correct AT command

  1. Step 1: To resolve the 'minicom dialing out error', you need to use the correct AT command to establish a voice connection. You can do this by adding the '+' and '*' characters to your ATDT command, like so: ATDT*131+xxxxxxxxxx*. This will enable minicom to establish a voice call over the cellular network.
  2. Step 2: Save these changes to your minicom configuration file and restart minicom. You should now be able to make voice calls successfully using the 'minicom dialing out error' fix.
  3. Step 3: Note: Make sure you have the latest version of minicom installed, as this issue may be resolved in newer versions.

Using pppconfig to enable voice over data

  1. Step 1: As an alternative solution, you can use pppconfig to establish a voice connection over the data connection on your phone. To do this, open a terminal and run the following command: pppconfig add device modem /dev/ttyUSB0. This will enable pppconfig to manage the cellular network connection.
  2. Step 2: Next, edit the pppconfig configuration file to include the voice settings: pppconfig edit device modem /dev/ttyUSB0. Add the following lines to the file: set device 1 'voice' 0. Save and exit the editor.

🎯 Final Words

In conclusion, the 'minicom dialing out error' can be resolved by using either minicom with the correct AT command or pppconfig to enable voice over data. By following these steps, you should now be able to make voice calls successfully on your Huawei e220 device with an AT&T SIM card.
