Why can't I send text messages on my oppo phone?

1. You can't send SMS, and you can't receive SMS and verification code at the same time.

1. If something is abnormal, it may be that the signal is bad or the network is blocked, which makes it impossible to send SMS. I suggest you try to leave this area for a distance, then restart your mobile phone or switch flight modes to see if you can solve the problem.

2. There are anomalies everywhere. Please change the machine and card for comparison test. If it is determined that it is a card problem, it is recommended that you contact the operator for handling; If there is something wrong with your mobile phone, I suggest you go to the service center for testing;

Note: If you need after-sales, please bring the purchase invoice, warranty card and mobile phone to the nearest OPPO customer service center, which will be tested and handled by professional engineers. Please back up and migrate your mobile phone data in advance before going (the safe and QQ WeChat data need to be backed up and migrated separately), and please contact the service center staff in advance to confirm the after-sales matters before going to the service center.

Second, you can't send SMS, but you can receive SMS or verification code normally.

1. If it is a new network transfer service, it is recommended to wait for the operator to open the SMS function before trying.

2. This situation may be related to the setting of the number of the information center. You can contact the operator to confirm whether the information center number of the mobile phone is correct. If it is not correct, you need to correct it in the SMS settings, and try to restart or switch the flight mode to search the network again to see if it can return to normal.

3. If the content of the short message contains special characters or some illegal content, it may be intercepted by the server after sending the short message. I suggest you check to confirm whether there is such a situation.
