Why do I receive a message at 1 1888 that the balance is insufficient?

Received a short message from 1 1888 to remind the user that the balance of the mobile phone account is insufficient. Generally, when the balance of the mobile phone account is less than 20 yuan, 1 1888 will send a text message to remind the user that the balance of the mobile phone account is insufficient, and it is suggested to open a payment assistant. You can reply to the specified code to 1 1888 to pay the local phone bill. Sometimes 1 1888 receives messages that are inconsistent with the actual situation, mainly due to the congestion of bills at the end of the month and the beginning of the month, which leads to the delay in payment. The actual phone bill has been changed when the text message is received. This information is for users' reference only. Please refer to the query of Nethall and no. 10000 is the actual phone bill balance. For more service benefits, click on "official website" customer service 35 below to answer your questions.
