Trilight Mobile
Nationwide coverage. Local Support. Built-in Savings.
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.
Get your first line free for a year. Here's how.
New to Cornerstone internet, or thinking about upgrading your current plan? Add Trilight Mobile and your first line is on us for twelve months.
- Sign up for new Cornerstone internet service, or upgrade your current plan.
- Enroll in AutoPay and Paperless Billing.
- Confirm you have an active leased Cornerstone Wi-Fi router.
That’s it. Up to $29.99/mo in credits applied for 12 months, and your $10/mo bundle discount doesn’t go away after that.
