"T-Mobile's Second Line Service: Cost and Testing Updates"
Originally Published 1 year ago — by TmoNews
T-Mobile is testing a new "Second Line" service in select markets, allowing customers to have a second number on the same line without data. Compatible devices can use a single physical SIM and an eSIM, or a couple of eSIMs. The service is similar to T-Mobile's DIGITS line but does not include data. Pricing starts at $25, with a discount available for customers with a voice line. This feature can be useful for separating personal and work contacts or for a side hustle.
