What if the mobile phone can't send text messages?

If you use an OPPO phone, you can refer to the following methods:

1. If you can't send SMS but can receive SMS, you can try the following scheme:

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. It is recommended to 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 short message contains special characters or some illegal content, it may be intercepted by the server after sending the short message. It is recommended to check whether there is such a situation.

2. If you can't send or receive SMS, you can try the following scheme:

1, some places use exception: if your early place is an area with poor signal coverage/densely populated area. Affected by the environment, there may be poor signal or network congestion, which makes it impossible to send short messages. 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. It is everywhere: you can 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 a problem with your mobile phone, it is recommended that you take the purchase invoice, warranty card and mobile phone to the nearest OPPO customer service center for professional engineers to detect and handle it. 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.
