How do I stop direct spam messages to Apple Ultra watch?

Is it a cellular watch with cellular service?

If so, contact your carrier. the watch has its own number, but that is ONLY supposed to be used for billing purposes and links to your primary line on the phone. It should not be receiving messages or calls sent to the billing number for the device.

Pretty sure the part that says it doesn’t have independent service would have been a “clue”, but I guess not. No, it doesn’t have its own service, it’s tied solely to my phone.

Check with your carrier though, as it may well have what amounts to independent service.

No it would not. Please educate yourself.

A cellular watch, though tied to the number of the phone it's linked to, has its own number that is supposed to be used for billing only. Unfortunately, carriers have a tendency to set things up incorrectly, allowing the watch to receive calls and messages sent to the 'billing number'.

Now answer the question originally posed. Is it a cellular watch? Do you have it activated for cellular service?

Note I did NOT use the word "independent".

If you can't answer simple questions, we can't help you.

A watch with cellular service would need its own independent service to be effective in that way. Please pay attention. Key words are simple, and spelled out in the initial post.

The reply you are objecting to here is probably correctly describing what is happening here; that your Watch (incorrectly) has what amounts to independent service.

The behaviour of cellular networks is programmable, and the network provisioning involved can be wrong. I’ve experienced operational errors from incorrect provisioning, as have others. In one of my cases, a rather tedious mess involving provisioning errors for Watch. A visit to a company-owned store and them then escalating eventually got that sorted.

By all appearances, the software managing carrier networks is complex, confusing, and not entirely reliable. Fragile, even. A Watch that has acquired the (incorrect for this case) provisioning (the ability for its number to receive texts) associated with semi-independent service would not surprise.

And even if that reply is incorrect, discussing a cellular function (texting) with your cellular provider is still the best available path toward resolution.

I didn't say "independent service".

Please pay attention.
