Indonesia mobile phone card can't receive SMS.

Indonesian mobile phone cards may not be able to receive SMS messages for the following reasons:

1. Cell phone signal is unstable: in the case of poor signal or no signal, the mobile phone card can't receive SMS.

2. Mobile phone settings: Sometimes SMS will be intercepted or blocked in the mobile phone settings, so check whether the SMS notification settings in the mobile phone settings are correct.

3. Non-Chinese mainland mobile phone number: At present, only Chinese mainland mobile phone number registration is supported. Please change to another mobile phone.

4. Mobile phone security software interception: For smartphone users who have installed security software, they can turn on the mobile phone security software, temporarily turn off the interception function, and then try to obtain the verification code again.

5. The SMS gateway is congested or abnormal: When the SMS gateway is congested or abnormal, the sent SMS will be delayed or lost. It is recommended to try to obtain it later.

6. Operator or service provider failure: Sometimes the operator or service provider fails, resulting in failure to receive short messages normally.

According to the above reasons, corresponding measures can be taken to solve the problem that Indonesian mobile phone cards cannot receive short messages.
