Is the area code for texting China Russian or China?

Your question is not very clear. Try to introduce you to several situations.

Let's talk about the problem of displaying the number first: I don't know why, whether at home or abroad (including Russian, of course), sometimes the area code displayed on the mobile phone is incorrect. In many cases, you can correctly display the mobile phone number you are using. Therefore, no matter where you are, the best way to save your phone number is to dial a plus sign (+), then the country code (such as 86), and then the phone number. For example: +86 1380000000. In this way, you can dial directly no matter where you are, regardless of the area code.

If you use a domestic mobile phone card to send a message to a Russian domestic mobile phone instead of saving the number in this way, you should add +86 before the domestic mobile phone number, so as to ensure that the information can reach the other party. There is a saying in China Mobile's information about roaming abroad. In this case, it is enough to send a domestic number directly. I tried, and I did. But I always feel unsafe.

If you send a message of Russian calling card from Russia to China's mobile phone card, you must add +86, or 8 1086, and then add China's mobile phone number. Your mobile phone number can usually be displayed correctly on the other party's mobile phone.

I don't understand what you said about Moscow area code. The area code of Moscow has now been changed to four regions: 495, 496, 498 and 499. In other words, there are four area codes for local telephones in Moscow, and different areas use different area codes. It is said that this is temporary. In a few years, the telephone area code of all Russia will be reset according to international standards. Now it's just a transition.
