Hat Island Phone Company?

I took my wife out to dinner tonight. Her cell phone rang with this number and she heard the spanish message and just hung up. Then about 30 minutes later I got the exact same call on my own cell phone. What the heck. We use T-mobile. Perhaps they got a T-Mobile list. What service do you all have? It just seemed too coincidental that we both got a call. We never give our cell # out and never get solicitations. So this was extremely weird and unusual.

Weird - I missed a call from this number earlier today on my cell phone (4:47pm Pacific) and didn't see it until this evening.  There wasn't a message so I was researching online, thinking it might be from a client I don't have in my cell trying to reach me - then I find this, very strange.  I have Verizon, not TMobile, so I don't think that's it.  Does anyone else live in CA?

received at 830 pm mst, did not answer, googled, looks like a boiler room for mexican american scam.

I got a call at 6:41 PST. I didn't recognize the number or the area code so I didn't bother answering. After seeing the other posts, I'm glad I didn't. I've been bothered enough by all these telemarketers/scams/etc.
