Whether it's an annoying caller or persistent ex, blocking messages on your apple watch can help stop unwanted interruptions. Thankfully, you can do it from your iPhone or watch itself. In fact, you can block numbers on both at the same time. To do so, head to your phone's Phone app and identify the irritating number or contact. Once you've done that, tap the 'i' icon and scroll down to 'Block this Caller'. Once blocked, the number or contact will not be able to text or call you.
On the other hand, you can block text messages on your watch by adding someone to the Messages list of Blocked contacts. This will not only block texts, but also prevent the contact from being able to use iMessage. To add someone to the Blocked list, open the Messages app on your iPhone and locate the conversation with the person you want to block. Tap the name or number at the top of the conversation and select 'Block this Contact'.
One important thing to note: blocking a contact will prevent them from calling or texting you, but it doesn't guarantee that they won't find another way around it. They could simply change their number or even start using a different service altogether.
If you have to stop receiving text notifications from a specific contact, the easiest option is to mute their notification in the Messages app on your iPhone. To do this, open the Messages app and locate the person who you want to mute. Once the chat opens, tap the name or number at the top of the chat and then select 'Mute notifications'.
