<p>With AT&T, you get a $10/mo discount if you get a phone line. The cheapest phone line, the measured rate, is ~$8/mo + taxes/fees = ~$12/mo. I got one because it’s nice to have backup when your cell phone doesn’t work, and it’s cheap.</p>
<p>In any case, if you’re experiencing excessive downtime with any internet, make sure your equipment is not at fault! Internet going down due to your laptop losing wireless connectivity = your equipment. The same applies if the router overheats. It’s only the provider’s fault if all your equipment is fully operational, but the uplink is having issues.</p>
