MiFiber is now Core Fiber

Same service & price

Your internet service and price will not be impacted by this rebrand – everything will continue to work normally, without interruption.

Same people & support

Our local office and staff are still here, you'll just see a new sign on the building.

MiFiber was built on providing exceptional customer support, and that will never change.

Core Fiber = more fiber

Along with our name change, we are accelerating our fiber internet construction throughout Newport and Priest River.

That means in the coming months fiber internet will be available to most homes and businesses in the area.

For customers in Newport or Priest River currently on a coax connection, you will have the opportunity to upgrade to a comparable fiber internet plan at no cost – or you can choose an even faster plan if you'd like. We will contact you once fiber is available at your address to schedule your upgrade.

New perks to get excited about

Our rebrand also brings exciting new experiences and opportunities for current customers.

Core Advocate

As a Core Fiber customer, you'll be assigned a Core Advocate. That means when you call, email, or text you're connected with the same person – your Advocate.

Referral program

Refer someone to Core Fiber in any of the towns we serve and you'll both get $50 statement credits!

New service areas

Here at home, we're building fiber internet throughout Newport and Priest River and will continue to expand our local fiber footprint. Additionally, we will begin serving more communities across Washington and beyond.

We're committed to building internet you can depend on

MiFiber has been a trusted innovator in the community for decades. Through MiFiber’s partnership with Core Fiber, our teams have worked side by side to expand next-generation Fiber Internet in Pend Oreille and Bonner County.

Today, we’re proud to have nearly 5,000 homes and businesses either connected to fiber or coming online this year. As part of this continued evolution, MiFiber is now becoming Core Fiber. Over the past several months, our teams have worked tirelessly to unite our companies under one brand, one mission, and one commitment to delivering a better customer experience.

We’re incredibly grateful for the loyalty and support of MiFiber customers, and we’re excited to continue bringing more fiber internet and next-generation connectivity to communities across the region.
