Why does my text message spontaneously say' I can't answer the phone now, I'll contact you later'?

Well, this is a problem with your mobile phone settings. If you keep texting, why can't I answer it now? I will contact you later to prove that your mobile phone has that demand. When you set up this phone, you will connect it. If you can't connect, I'll send you a text message directly. First of all, you should look at your settings, set up your short messages, and look at the problems of answering and transferring calls. This has nothing to do with other things, it's your mobile phone consultation.
