Who called from 7633901121

Received a call on my cell phone from this number. Area code is Minneapolis, MN.

Finally answered call as I didn't recognize number and they've been calling every day.  GCI cable offering me a "special deal."

Got one call 6:15 p.m. this Tuesday evening.  Did not pick up, no voice mail left.

I looked up the area code, and it was (apparently)in Minnesota.  I was wondering if it is just another one of many caller ID's of Time Warner Cable, who uses multiple caller ID's.

"Cable" as the company is awfully generic.
