Can I send a text message if the other party's mobile phone is in arrears?

If you just owe money and don't stop, you can collect it! Well, the message sent by the mobile phone stays on the SMS platform of the operator first! So there is a short message validity period in the short message settings! Can be set to the maximum value, the message can be saved for a long time! You can receive it when the other party's mobile phone is turned on.
