how do i hack calls and sms of a mobile phone?

spynote6.4  but you will need a crypter for bypass antivirus and google protect

Is spynote windows only or Linux too

I'm pretty sure SpyNote is windows only since it uses JAVA if I'm not wrong, but i would recommend you using Kali Linux generating ur own payload. There's plenty of tutorials on the internet for that. Note: It's not persistent at all so once its gone it's gone so make sure to not disconnect the victim somehow.
