Turn on Airplane mode for 1 minutes then reboot yo... @gateio

Answer 2: To turn on Airplane mode for 1 minute, open your phone's settings, then tap on the Airplane mode option and turn it on. After 1 minute, turn off Airplane mode and restart your phone. Once your phone has restarted, try sending a new SMS code. Make sure that you have a strong cellular connection or Wi-Fi connection before sending the SMS code. If you still have difficulty sending the SMS code, try restarting your phone again or contacting your phone service provider for further assistance.

Ok
