I just received another SMS which was quickly considered spam from the Google messages app, along with a link to this scam website
ledgeractivate.com
or this phone number.
2111987675
I called, an English speaking person picked up, of course, the call wasn't from Greece, sounded like he was trying too hard to sound native English though.
Edit: Now that I'm looking at the website, the landing page is an exact copy of the actual Ledger website.
I think you need to change your number to a new one, as this second message containing a scam indicates that your number has been targeted by scammers. It is good that the message was marked as spam, as the site is indeed a phishing site that was created 11 months ago. I think they will not stop sending you such phishing messages, so you need to secure all your accounts linked to this number with additional security methods.
I will now file a report to the fraudulent domain registrar so that it can be completely restricted, as it poses a threat to users who received the same message and might think they are dealing with a legitimate site. As for these numbers, try to ignore even contacting them and putting them on the blacklist; you don't know how their tricks might be used to persuade you.
