What text message should I send to check the age of my mobile phone?

Is there such a short message? I don't know about this, but you can call customer service to ask, and it's no trouble. Mobile customer service is the most convenient to find, so I won't say anything else. Anyway, I have used mobile, so I won't talk about the process. Anyway, customer service is easy to find. When connecting, ask the card processing time directly, and people will tell you directly that the whole process should not exceed 2 minutes.
