My friend is a subscriber of China Telecom 189, in Chengdu, and I am a subscriber of China Mobile 138, in Shanghai. We usually want to make phone calls and send text messages.

China Telecom, of course. For the record, I am not a telecom nurse. I used China Mobile and China Unicom before. I used 189 and stopped using all GSM services that I have used for many years, but I just felt it.

First of all, the signal is good, there is no dead angle, and the kitchen, bathroom, elevator, subway and wild mountain area are all fine. Second, it is cheap. Choose a package that suits you, and the price is similar to other packages. Third, telecommunications can set up a home number for free.

You can consult customer service first.

Telecom can also use the email address of 189 to send short messages to any mobile phone for free, 300 messages a month.

I hope it will help you, and I hope it will be adopted. Thank you!
