Trilight Mobile

Nationwide coverage. Local Support. Built-in Savings.

hello!

Your phone plan should be as reliable as your internet.

Most people don’t think much about who their mobile carrier is, until something goes wrong and there’s nobody local to call. Trilight Mobile gives you nationwide coverage on a network you can trust, backed by the same Cornerstone team that’s already in your corner. And if you’re already a Cornerstone internet customer, bundling your mobile service saves you money every month. Simple as that.

Multiple Ways to Save

When you switch to Trilight Mobile, you get to choose how to start saving money.

Get your first line free for a year.

When you make the switch, your first line is free for a whole year. You’ll receive credits applied to your Cornerstone internet bill for 12 months, and your $10/mo bundle discount doesn’t go away after that.

OR

Get $600 toward a new device.

Switch to Trilight and get $600 in monthly credits toward your new device for the next 36 months for your first line, and $400 for each additional line (lines 2-10).

Our local team is happy to help you figure out which option saves you the most.
