No SMS verification code can be found in mobile phone dialing.

The mobile phone can't receive the verification code, probably because the mobile phone is in arrears, which makes it impossible to send and receive short messages normally.

2. Blacklist software interception

Adding the number that sent the verification code to the blacklist or being intercepted by the security software installed in the mobile phone will also lead to the failure to receive the verification code.

3. Poor network environment

It is best not to verify in the place with poor signal, which will not only delay the reception of verification code or fail to receive verification code, but also lead to the decline of mobile phone power.

4. Apply to the operator for shielding.

If some notification messages have been complained by operators as spam messages, such messages will be blocked by operators and mobile phones will not be able to receive such information. We can call the customer service phone of the mobile phone operator first, verify the problem, and then apply to the operator for unblocking.

5. There is something wrong with the sender.

When we register an APP and need to verify it, we can't receive the verification code for a long time, which may be caused by an error in the other party's system. We need to wait patiently for a few minutes. If you still can't get it, you can contact the customer service of APP.
