How to exchange telecom points for phone bills in SMS?

Telecom mobile phone users can directly edit the short messages "DHHF 10", "DHHF20", "DHHF30" and "DHHF50" (case-insensitive) and send them to 1000 1688 (this short message is charged according to normal short messages) to exchange the corresponding phone charges; 1000 is RMB 10, 2000 is 20 yuan, 3000 is 30 yuan, and 5000 is 50 yuan phone bill (you will receive the phone bill within 4 hours). The above information is for reference only. Guangxi Telecom's worry-free card costs only five yuan a month, and the traffic charges step by step. The more you use it, the cheaper it will be. For details, please visit the online business hall of Guangxi Telecom, and the customer service will answer your questions on the 24th. /UrlDispenseApp/index.php
