Someone walk me through enabling imessage on iphone?

once it says it's on, tap Send & Receive on that same Messages screen. your phone number should be ticked there. if only your email shows, the number side never activated, so people texting your number still get green bubbles. signing out of your apple account just on that screen and back in usually kicks it.

Toggle is in Settings > Messages (Settings > Apps > Messages on iOS 18 and later). Turning it on is the easy bit. What usually trips people up: - it needs wifi or data the first time, plus a SIM that can send a normal SMS, because activation texts Apple in the background - "waiting for activation" can hang for hours. leave it, or toggle off, restart, toggle on - check the date and time are set automatically, wrong time breaks activation Once it's working, blue bubbles to other iPhones, green to everyone else.
