This T-Mobile fiber deal delivers a free month plus a $100 bonus — how to claim this limited-time offer

TL;DR: Sign up for T-Mobile Fiber 2 Gig for $70/month with Fiber AutoPay and get your first month free, plus a $100 virtual prepaid Mastercard for a limited time.

T-Mobile is giving new fiber customers a reason to upgrade their home internet. For a limited time, customers who sign up for the Fiber 2 Gig plan can get their first month free, plus a $100 virtual prepaid Mastercard after installation.

The Fiber 2 Gig plan is $70/month with Fiber AutoPay (plus taxes and fees), saving you $10 compared with the standard $80/month price. The promotion applies to new T-Mobile Fiber internet lines and does not require a T-Mobile wireless plan.

How to get the T-Mobile Fiber 2 Gig deal

To take advantage of this offer, you’ll need to:

• Sign up for a new T-Mobile Fiber 2 Gig internet line

• Complete your installation by the required deadline

• Keep your service active and in good standing

T-Mobile will include your first month of service, and the $100 reward will arrive as a virtual prepaid Mastercard after installation. The company says to allow up to 14 weeks for the card to arrive.

T-Mobile Fiber offers a 100% fiber internet connection with unlimited data, including the equipment and installation needed to get started. The Fiber 2 Gig plan comes with:

• WiFi router

• Professional installation

• Mesh WiFi extender if needed, based on installer assessment

• Exclusive T-Mobile Tuesdays perks

Because fiber connections use dedicated fiber lines rather than traditional cable connections, upload speeds can match download speeds, which is helpful for video calls, cloud backups, and transferring large files.

T-Mobile also offers lower-speed Fiber options, including Fiber 300 Mbps for $45/month with AutoPay. It includes unlimited data, a router, installation, and T-Mobile Tuesdays perks, but it does not qualify for the current Month On Us promotion.

Fiber 1 Gig costs $60/month with AutoPay ($70/month standard) and includes the first month on T-Mobile. It comes with a mesh WiFi extender if needed after installation.

What to know before signing up

The Fiber AutoPay discount requires payment with a bank account or debit card. Using another payment method means you’ll pay an additional $10/month.

The $100 reward comes as a virtual prepaid Mastercard that expires after six months. T-Mobile says the value of the card can be charged back if you cancel service within the first year: the full amount if you cancel within 180 days of installation, and 50% if you cancel within 364 days.

T-Mobile Fiber is also not available everywhere, and pricing can vary based on your service address. You’ll need to check availability before signing up.

The 2 Gig plan is the real draw here. Assuming T-Mobile Fiber is available where you live, you can get a month on the house plus $100 back.
