Hi - figured someone on this board could give me the best answer to this question. I'm thinking about getting the Apple Watch 4 but I'm concerned about notifications. I get a lot of sms messages from a monitoring system at work and I don't want to see them on my watch. Will you only see imessage messages on the watch? Can I filter by sender - or maybe just block sms to the watch? It's going to my cell phone number. Not planning on getting one with cell service. Thanks in advance for any help.
