What is the reason for the failure of sending credit one-time recharge authentication SMS?

There are several reasons for the failure of sending recharge authentication SMS:

1. It may be a network problem. If you only do this once in a while, or if you are always good, you will suddenly fail to send it once. This may be the reason why the local network is busy. You can try again later.

2. After the first case is ruled out, it may be that your SMS service center number is set incorrectly or has been modified. I suggest you find the number setting of SMS service center in the setting item of SMS menu. Mobile users should be +XYZ500, where +86 cannot be omitted, XYZ is the area code, such as Nanjing 250, Shanghai 2 10, Suzhou 5 12 and so on.

3. If the above two situations fail, then you can only judge whether it is a card problem or a mobile phone problem by changing the machine and card. You take out the card and put it in a normal mobile phone to see if it's ok. The problem of the card can be eliminated. If it is a mobile phone problem, you should go to the customer service center for testing.

4. The server instability of this platform may also lead to the failure of sending authentication SMS.

Supplement: sending the recharge authentication SMS failed, without trying several times, or calling the platform directly to confirm.
