The telecom number has just been changed successfully. How long does it take to send a text message to your mobile phone?

Hello, first of all, thank you for your support to China Telecom. According to your description, are you talking about the service password modification of telecom mobile phones? If there is, I will receive it as soon as I change it, and I will be reminded by SMS. Modifying other passwords is also issued in time, generally speaking, it does not exceed one minute.

I hope my answer can be adopted by you.
