Blocking sms with no numbers

[CCKC]

I have been getting scam sms every 30-40 from a sender with no number.  How can I block thes messages if it have no number?  I tried to block sms with phrases but can no longer find that feature.

Hi , sorry to hear that this is happening to you. If you're using Samsung's Messages app, you can block conversations. To do this, open Messages > ⋮ > Settings > Block numbers and messages > Block numbers > tap Conversations > tap on the conversations you would like to block.

Hope this helps!

Thanks for that. I have tried that but it says invalid number so it can't be blocked.

Hmm, then I would suggest adding them as a contact and blocking them as a contact. Hopefully this should help!

There is no option to add them as its saying invalid number. Only option is to delete but it'd sending me over 20 messages a day.

Hmmm, the only other solution I can suggest is manually inputting that number into Block numbers (both with the + and without). If this doesn't help, the best course of action would be calling your service provider.
