Got a text from this number in Spanish telling me that someone picked up something (which I'm assuming is a money transfer) from Intermex (an international money wiring service) and to reply with STOP to cancel notifications. I received another similar message from a different number one day apart. I do not believe these texts are legit. I think they just want you to reply so they can see if it's a live number. I use Truemessanger to block unwanted texts instead of acknowledging them.
