SMS/MMS vs. iMessage: What's the Difference?

Understand Apple's internet-based messaging versus carrier messaging.

Quick Answer

iMessage uses Apple's service between compatible Apple users; SMS/MMS uses carrier messaging and can work with non-Apple phones.

Step by Step

  1. Use the platform's official app or website and confirm you are signed into the intended account.
  2. iMessage uses Apple's service between compatible Apple users; SMS/MMS uses carrier messaging and can work with non-Apple phones.
  3. Review privacy, audience, recipient, or recovery settings before confirming important changes.
  4. For account-security problems, secure the associated email account and enable two-factor authentication when available.

If That Doesn't Work

  • Social-media menus and features change frequently and can differ by device, account type, region, and app version.
  • Do not send money, passwords, one-time verification codes, or sensitive personal information to an account merely because its name or photo looks familiar.
