Yes, new and upgrading customers on the T-Mobile Rely Internet, T-Mobile Amplified Internet, and T-Mobile All-In Internet plans are covered by our 5- year Price Guarantee. 5-Year Price Guarantee means that we won't change the price of fixed-wireless 5G internet data for at least 5 years while you are on an eligible plan. Taxes & fees, voluntary equipment or speed upgrades, future wireless generations, select limited-time promotions, per-use charges, third-party services, and network management practices aren't included. This guarantee starts when you activate or switch to an eligible plan and doesn't restart if you add a line or change plans after that.
