the best thing to do is not to call the number back right away , and block your number if they see you called back they sale your number to more SPAM senders
I have been receiving several text messages this week from different numbers with area code 520. This is one of them. This one is offering $1500 quick cash. Another offering debt consolidation, and another is sending religious messages. I do not have text message plan, so I don't want to be charged for unsolicited messaging. How did they get my number???
If you call the number back, after several rings, you get message that voicemail has not been set up.
