Phones near a blaster can be forced to connect to its illegitimate 4G signals, before the blaster pushes devices to downgrade to the less secure 2G signal.
How many phones still support 2G? If its a lot I suspect a security patch or firmware update could fix that. They do link to this [1] for Android, a setting I do have.
They then push the scam messages, which contain links to fraudulent websites, to the connected phones
Seems like disabling non-HTTPS could also be done through an update. Plenty of scammer sites have legit DV certs though.
