Why can't my telecom mobile phone card only use data traffic, and wifi can't receive long messages? The wifi that comes with the mobile phone can't be used, and the text message can't be returned.

Hello, first of all, thank you for your support to China Telecom. According to your description, wifi can only be used in the coverage area of chinanet, a wireless hotspot of China Telecom. You can check whether there is coverage of this hotspot around you. If yes, search the network, enter the mobile phone number and SMS verification password, and you can enjoy the high-speed wireless network of China Telecom.

China Telecom's 4G has been officially commercialized. If you need to inquire about 4G tariffs, check bills, pay phone bills and buy mobile phones, please visit the online business hall of Anhui Telecom. Wish you a happy life!

I hope my answer will help you and be adopted by you!
