What should I do if I don't get SMS authentication code?

If the mobile phone Internet is not smooth, you may not be able to receive SMS authentication code text messages. Please try again in 30 minutes.

In addition, please check your mobile phone situation through the following procedures:

• Please check the status of the cell phone signal status. If the signal is not stable, please try where the signal is good.
• Please close the spam function and blocking function of your phone.
• Turn off your cell phone and turn it on again.
• Get an authentication code through the voice message function.

If you can't solve the problem by the above method, please contact the online customer center.
If you tell us your mobile phone model name, operating system (iOS, Android), and location country/region, we will quickly contact your SMS supplier to solve the problem.
