How can I make an international roaming call when I am going to travel to Turkey?

When traveling in Turkey, if you need to make an international roaming call, you can follow the following steps:

1. First of all, please make sure that your mobile phone has opened the international roaming service. If it has not been opened, you can contact the mobile phone operator before going abroad. For example, in China, you can apply through 10086, or you can apply in the operator's business hall.

2. When roaming in Turkey, if you need to make a domestic fixed telephone call, you need to add 0 before the fixed telephone area code. For example, to make a landline call to Beijing, you need to enter +86 1085070809.

3. If you want to call China's mobile phone number, you only need to enter the other party's mobile phone number.

Please note that different countries have different international roaming charges, different operators and packages, and the specific charges may be different. If you need to know more about roaming charges between Turkey and China, I suggest you consult your mobile phone operator or consult the relevant mobile phone roaming guide.
