If the other party blocked my message and I sent it, can it still show that it was sent successfully?

SMS shielding can be divided into mobile phone shielding and carrier shielding. If the operator blocks you, your mobile phone number is likely to be disabled, and it will not be handled like this if it is not a mass advertisement. Under normal circumstances, people use the shielding function of mobile phones to shield them. This is actually that your SMS has been sent successfully, but the other party's mobile phone automatically drags the received SMS into the darkroom and does not display the normal reception signal.
