- CommonSender accidentally blocked or on a blocked listA number can end up blocked without you remembering doing so.

What to do
- Check your blocked contacts list to make sure the sender isn't blocked.
- Check Do Not Disturb, Focus modes, and notification settings for the messaging app.
- If you switched from an iPhone to Android (or vice versa), deregister iMessage for your number through Apple's account tools, since this is a very common cause of lost texts after switching phones.
- Ask the sender to try sending as a plain SMS and see if that arrives.
- Restart the phone to refresh its message sync.
- Contact your carrier if messages are missing from multiple senders consistently.
When to call a pro
If you recently switched from an iPhone and messages from iPhone users aren't arriving, deregistering iMessage through Apple's official tool usually fixes it; contact your carrier if the issue is broader.
