Call the customer service phone of China Unicom or China Mobile to ask how to block the letter service (Unicom) and the cool letter service (Mobile), and then send the corresponding SMS according to the customer service prompts! In this way, we can avoid the phenomenon that sp service providers collect fees in disorder and mobile phone built-in programs send short messages in disorder! The following is my example. I am a Unicom user. I found that the newly bought mobile phone always sends several text messages to 10668088 automatically every day, and the amount of deduction varies from 1 yuan to 2 yuan. So I consulted the customer service, and sent PBYW (Chinese Pinyin initials for blocking business) to 1065 133 for solution at the prompt of the customer service.
I hope my example can help you solve the problem of mobile phone charging, and at the same time, don't give those greedy sp service providers an opportunity!
Welcome to forward my post, or tell your friends and family around you to help more friends who are troubled by the phenomenon of unreasonable charges on mobile phones!
