<p>We have an AT&T phone system in our house with bluetooth capability for two cell phones. When we make long distance calls, I simply hit the “cell” button, choose which cell number I want to use (DH’s or mine) and it uses our free minutes. We could feasibly use three of the handsets at the same time, one for each cell phone number and the landline number. We’ve talked about going to cell-only service, but our internet service, TV and phone are bundled and it just seems easier to keep it.</p>
