I have a dual SIM on an iPhone 12 running iOS 17. My contacts are divided into personal and business. When the phone rings, the screen will say either (B) or (P) in a way too small font, btw, but that's not the subject of this message. At all times of the day, I get text messages which say: "iMessage, followed by the date." Then the txt. How do I figure out if this is being texted to my personal SIM or my business SIM?
