How does China Telecom Broadband set up a blacklist for home phone calls?

Dear telecommunications users, hello!

According to your description, it depends on what terminal you are using. There are many brands of landline phones and mobile phones. If your landline phone has a blacklist function, you can set it up. Hope it helps.

If you need to buy a mobile phone, you can go to Anhui Telecom Tianyi Store (/shop/) to buy hundreds of mobile phones at low prices on the entire network.
