What is the reason why the text message can't be sent out?

Mobile phone arrears, wrong number setting in SMS center, network signal problems and other reasons.

1, mobile phone arrears: this is an easily overlooked reason. If your mobile phone subscription has been used up or exceeded, or your mobile phone account balance is insufficient, your SMS function may be restricted or disabled, so that you cannot send SMS. The solution is: recharge in time or change the package, and then send a text message again.

2. SMS center number is set incorrectly: SMS center number is a special phone number, which is responsible for receiving and forwarding your messages. If you set the wrong SMS center number on your mobile phone, your SMS may not be processed and sent correctly. The solution is: according to the operator and region you use, query the correct SMS center number, and then modify or add the correct SMS center number in the SMS settings of your mobile phone.

3. Network signal problem: If the network signal in your place is poor or unstable, it may affect your SMS sending and receiving. The solution: try to change the location or wait for the network to return to normal, and then resend the SMS.
