Hi,tada guys. I am a traveler from China who is in Seoul. I can't receive your registration verification code. My mobile phone number has changed operators in China. From China Mobile to China Telecom. The customer service of China Telecom replied that this problem would occur when changing the mobile phone number of the operator, because some foreign verification code systems did not update the data in time. Can you ask your supplier of verification code system to solve this kind of problem?
