Why is there no SMS reminder for cancellation of telecom card?

There may be the following reasons why there is no SMS reminder when the telecom card is cancelled:

1. SMS storage is full. The short message storage capacity of mobile phone is limited. If you don't clear the received SMS in time, you won't receive the follow-up SMS. It is recommended to delete the message and try again.

2. Your mobile phone is not turned on for a long time or in a place with poor signal for a long time, which will make the short message sent to you invalid because it is expired. Suggest trying somewhere else.

3. Related to the local gateway. Due to the large number of local short messages in some time periods and the busy short message center, short messages may be delayed or lost due to the impact. Suggest trying somewhere else.

If all the above reasons are ruled out, I suggest you plug your calling card into other mobile phones to see if you can send and receive short messages and confirm whether it is a mobile phone problem. If the problem still exists, please consult customer service or bring your ID card to the local telecom business hall for handling.
