I bought a micro-medical APP, but the registration has been unsuccessful. What if I can't receive the verification code at all? In a hurry, online, etc.

Generally, the registration of this kind of software needs to confirm whether there is SMS interception or blacklist setting, or you can try to change your mobile phone number to another mobile phone to see if it can be received normally. The validity period of the verification code is generally 5- 10 minutes. When they expire, they will automatically become invalid and prompt you "verification code error. If it is a webpage, you can contact online customer service to try to solve it. Or call customer service directly at 95 169.
