From the comments, it seems that the phone number belongs to some telemarketers.  Telemarketing cold-calls to cell phones (without a prior consent or prior business relationship) are forbidden by law (FTC regulation).  Even if the telemarketing company is offshore (e.g. in India), the U.S. client company can still be fined.  See the FTC website:
http://www.ftc.gov/bcp/edu/pubs/consumer/alerts/alt107.shtm
which states:
32.    Are telemarketing calls from overseas covered?
Yes. Any telemarketers calling U.S. consumers are covered, regardless of where they are calling from. If a company within the U.S. solicits sales through an overseas professional telemarketer, that U.S. company may be liable for any violations by the telemarketer. The FTC can initiate enforcement actions against such companies.

You should tell the telemarketer (if you can actually speak to someone) to take you off their call list, and if they do not comply you will report them to the FTC (at www.donotcall.gov), AND that you will also complain to their client company (e.g. the newspaper company that they are telemarketing subscriptions for) and tell their client company that they may be fined in an enforcement action.  

Even if they are "giving away" a trial subscription, they are still telemarketing - if you (1) promise to cancel before the trial period is up, or (2) promise to pay for the renewal after the trial period, the promise is an obligation you are taking on (either way), and is an exchange of consideration.  This exchange of consideration is payment for the trial subscription, thus this is "commerce" and is telemarketing.

I got this call at midnight 11:53pm. If they do that again, I will  call police!!!

got this call at midnight again and again!!!

By calling the POLICE (I hope NOT 911). What would you being saying to them (as to the nature of your call)?  


"aaahhh, Hello, POLICE DEPT:......
It’s almost midnight and I just now got a phone call from someone (i.e. a solicitor)trying to sell me a newspaper subscription from the SF Chronicle and I want to make a complaint because they shouldn't be calling people this late at night." etc, etc...



By calling the police,  it would fall into the same category as to this story:

LIKE THE RECORDING OF A PERSON WHO HAD CALLED 911 because....

there was a spider in there house and the person calling, feared spiders, and they were afraid it was going to bite them and wanted the spider out of there house.....




(RECORDING WAS AIRED ON A TV PROGRAM)

Someone noted here on this page (see above) that the caller said they were from the SF Chronicle.

                                    JUST.........

Make a call to the SF Chronicle (to there subcription dept. and ask to speak w/ a Supervisor) or maybe call there main number (you may have better luck w/getting "live person")  and ask that you would like to speak to the person who is in charge of there "tele-marketing dept. and make your compliant from there....
