What's wrong with installing Golden Sun and not returning messages?

1. What mobile phone are you? Mobile, Unicom, or Tianyi. You can usually receive it by sending it to 95536. In rare cases, if there is a problem with the SMS channel, you need to send an alternate number.

2. Mobile phones have blacklists and whitelists. If the customer's mobile phone is blacklisted, it is impossible to receive text messages.

3. Whether the format is correct "DB+ space +A", and the letters cannot be full-width letters.

It doesn't matter if you can't receive the message, as long as you can install it.

Try again every once in a while. Maybe the information was recovered.
