Failure to receive the verification code is generally caused by settings or network issues. It is recommended that you use the following methods to troubleshoot:
1. Please confirm whether your mobile phone can send and receive SMS normally.
2. Make sure your mobile phone can access the Internet normally. If the network is unstable or the signal is weak, please switch networks or move your location.
3. Please check whether your mobile phone has turned on "spam & blocked" function. If so, please turn it off or add it to the whitelist.
4. Please try changing to another normal SIM card to see if you can send and receive verification codes.
