Telecom-bound mobile phone, how to clear all the records in the mobile phone card?

Hello, first of all, thank you for your concern and support for China Telecom. According to your description, the mobile phone card can only store a certain amount of short messages and address books. You can enter short messages and contacts, and then empty them, and empty the information in the mobile phone card.

Telecom broadband speed-up is free, 4M to 8M, 12M, 8M to 20M, 20M to 50M. You can go to the nearest telecom business hall or call 10000 to speed up for free. Please visit Anhui Telecom's online business hall for details.
