There is money in the mobile phone card, but I can receive the text message, but I can't send it out and I can't get on the Q. What is the situation?

There are two situations:

1, the balance on the mobile phone card is not enough to send a short message (when it is less than 0. 15 yuan), resulting in that the received short message cannot be sent.

2. At this time, ICP's monthly rent or some value-added services were issued, but the balance on the card was not enough to cancel the account, which led to the receipt of the text message but could not be sent out.
