In Korea, you can make a call to China by following these steps:
1、Open your phone and select the international dialing code, which is usually "00".
2、Dial the country code of China, which is "86".
3、Follow with the area code of the city or region in China you are trying to reach.
4、Finally, dial the phone number of the person or business you are trying to contact.
For example, if you want to call a number in Beijing, you would dial "00 + 86 + 10 (Beijing’s area code) + phone number". Please note that area codes and phone numbers may vary depending on the location in China you are trying to reach.
You may also consider purchasing an international phone card or using online calling services like Skype, WhatsApp, or Viber to make international calls at a lower cost. These services often provide better quality and more flexibility than traditional phone lines.
