Short answer is that you can't. At least not from the phone number. Numbers here are broken down into aaa-bbb-cccc; (aaa=area code; bbb=exchange; cccc=number). The area code tells you what state the phone was/is issued in, the exchange gives you the general area, and the number is simply sequential. There's no "Service Class" indicator.
My brother's cell phone was issued in Connecticut, has a 203 area code. He's lived in California for almost a decade now. So, you can't even reliably tell from his phone number what state he lives in. Connecticut's on the East Coast of the USA, California's on the West Coast, we're about as far apart as we can be and still live on the same continent. -----Original Message----- From: u2-users-boun...@listserver.u2ug.org [mailto:u2-users-boun...@listserver.u2ug.org] On Behalf Of Symeon Breen Sent: Wednesday, July 10, 2013 7:12 AM To: u2-users@listserver.u2ug.org Subject: [U2] Mobile phones Hi I have an application that is based in the UK, one of the things it does is allow entry of a phone number, I then determine if this is a mobile (cell phone) and send a text (easy in the uk as all mobiles begin with 07) We are embarking upon our first US client (well existing uk customer with a US presence) so my question is - how with US phone numbers can I determine if it is a cell phone ?
