T-Mobile launches 10% lifetime referral discount via T-Life app
T-Mobile's new referral program lets subscribers share a 10% lifetime discount on voice lines with friends and family through the T-Life app.
T-Mobile has launched a referral program that lets existing subscribers share a 10% lifetime discount on voice lines with friends and family. The offer is available in the T-Life app under the Benefits tab, according to The Mobile Report.
Each voice line on an existing postpaid account has its own unique referral link in the T-Life app, so subscribers can share multiple invites. The discount stacks with standard promotional offers such as phone trade-in deals, Keep & Switch incentives, and device credits.
New customers must port in an eligible number from a competing carrier within 14 days of checkout to qualify. The promo is slated to run through November 17, 2026.
The move marks a shift from T-Mobile's traditional Insider Codes, which offered a 20% discount on voice lines but required an employee connection. T-Mobile has frequently revamped its ecosystem, including new perks and testing value plays like its Super Essentials Saver Walmart plan. Historically, the carrier has left grandfathered Insider discounts untouched even across multi-year plan migrations.
