Additional Information

When you turn on iMessage on your iPhone 15, you’re unlocking a world of messaging possibilities. But there are a few things to keep in mind. First, you need a data plan or Wi-Fi connection to use iMessage since it relies on the internet to send messages. Second, if you ever switch to a non-Apple phone, make sure to disable iMessage first, or you might not receive texts from iPhone users.

Another tip is to customize your iMessage settings further. You can set read receipts, choose whether to send as SMS when iMessage isn’t available, and even filter messages from unknown senders. Also, remember that while iMessage is free, it does use data, so keep an eye on your usage if you’re on a limited data plan.
