This ensures your message still goes through the traditional way, though carrier charges may apply.

Another handy feature is the ability to send and receive messages from your Mac or iPad. By signing in with your Apple ID, your conversations are synced across devices, making it easy to stay connected no matter what device you’re on. Just remember to keep all your devices updated to the latest software to ensure compatibility and security.

And let’s not forget about customization. iMessage lets you add a personal touch to your messages with various effects, stickers, and GIFs. Plus, with the ability to react to messages with Tapbacks, you can quickly show your emotions without typing a word.
