My Pixel 8 pro is excellent at rooting out those texts and just blocks them. Wish I could find something similar for my Galaxy phones.
I have a galaxy s10e through work, and it allows blocking pretty easily. Since it is a New York City number, (I'm in Kentucky) I get alot of wrong numbers, and spam calls.
The ones I had the most difficult time blocking where the group texts, MMS ones.
IDK if it is a employer policy that allows the easy blocking but it is a little bit better than my Motorola Edge plus. Or I should say easier.
The biggest thing is to not respond, you will eventually drop off their target list.
I guess I just have to delete them. Been getting a couple of texts a week from them.
They make me anxious about identity fraud though. Baffled as to why I get them (keep asking me to log into 'my account', when I have no such account and had never even heard of this company before they started texting me). Even if they are a scam, I can't figure out what the scam is, what it is they expect to get from doing this. If it's "phishing", what are they phishing for, and how come the text gives what seems to be the correct number for this company? Unless the company website I found (independently of the texts) is _also_ fake? Though they seem to be mentioned all over the web as a legit company.
That the whole thing is so baffling just makes me more anxious as to what it is I'm not seeing about this.
In fact, in general these days, I feel myself sliding into paranoia, when I add in all the ridiculously-obvious scam calls I get on the landline ("This is the fraud department of your bank" - literally that's what they say, announcing themselves as being "your bank"!), and dodgy emails.
Some of the same as above applies here, DO NOT respond, otherwise over time you will fall off the target list.
At one time I followed a shared link from FB from someone I knew, about job opportunity at Budweiser, well it was a bust. This was 7 years ago maybe 6. Anyway I made an outlook email address to make it look more professional. (might have been gmail IDR) but it completely ruined that email, all the spam, click here to unsubscribe didn't work, it was like just passed along. Every unsub resulted in 5 new subs it seemed. I just let it goto the graveyard.
Now I have gotten texts, that were like group texts, with multiple numbers, different country codes, those were difficult to block. IF and big IF here, I think I traced it back to a what'sapp email, the originator, and finally blocked it.
I will tell you though it's phising, they will pester for weeks, but if no bites, it'll move on.
If you reply, then they will persist. The FB marketplace, and other mass selling sites were the cause of alot of my problems trying to sell a tanning bed.
I use verizon, they have a spam filter on Calls, works pretty good. I can figure you are in UK, maybe contact your service provider.
Me, I don't have anything the can really take, so sometimes I will play with them. But if you do have Equity, then put a authenticator or talk to your countries credit agencies, they can usually put a 2FA on you so that you can be contacted if someone tries to open something with your info.
My wife's parents are in this category, so I have to be diligent with them, so my Mother in Law has everything locked until they want to make a decent sized purchase.
Maybe UK has something like that?
Sorry for the wall of text.
