I can’t receive all texts

Hi

How notifications behave depends on the status of your devices and your settings. With Wrist Detection enabled, in order to bring notifications to your attention as soon as possible:

• If your iPhone is unlocked, then you will receive notification alerts on your iPhone instead of on your Apple Watch.
• If your iPhone is locked or asleep and your Apple Watch is unlocked (regardless of whether the watch display is asleep or awake) and on your wrist, you will receive notification alerts on your watch.
• If your Apple Watch is locked or has Do Not Disturb enabled, then notifications will go to your iPhone.

What you do mean you only get some? Are you not getting them at all, or is it that you are not getting notifications? Are these iMessages, or SMS (text messages) that come from non-iOS devices? What troubleshooting have you tried?

iMessage requires data, either wi-fi or cellular, and SMS require cellular be active. If the problem is SMS, contact your carrier. There are no settings for SMS on the iPhone.
