I got spam SMS txt from this number on both my phones

Don't reply "stop." They'll use that reply to confirm that you're on a mobile and are receiving their texts.

Instead, use this form to report them to the FCC. This type of unsolicited messaging is actually illegal:

Here's their service provider, feel free to give them a call as well:
