T-Mobile frequently runs promotions that offer a free or discounted line to customers who open one or more paid lines. When asked if these free lines were converted into paid lines later on, T-Mobile‘s President of Consumer Group, Jon Freier, hinted that the question missed the bigger picture.
Freier said that analysts often use free lines as a gauge for the quality of the customer base. He pointed out that the increasing postpaid service revenue showed that the customer base was strong.
Freier also revealed that free lines were a retention tool, targeted toward customers contemplating moving their accounts away. This could potentially help disgruntled customers stay with T-Mobile for up to three years longer than they would have. This increases their Customer Lifetime Value (CLV), or the total revenue they generate over their tenure at T-Mobile.
Then, of course, we have an opportunity to further differentiate and deepen that relationship, too, with other products and services and get more and more adoption from things beyond the smartphone, whether that be tablets or watches or fixed wireless with our 5G home broadband.

While the majority of the respondents were fine with free lines being used to generate more business for T-Mobile, 1,406 (29 percent) found it dodgy.
Others had a mixed opinion but were comforted by the fact that they were still receiving value from their extended time at T-Mobile, even with potential increases in spending. Some shrugged it off, highlighting that free lines weren’t binding in any way.
Customers understand that corporations aren’t charities and that they have ulterior motives behind their every action. Their tolerance in this case is likely due to the fact that they are getting a good deal in return. This serves as an example for companies that not only want to retain customers, but also want them to increase spending. Customers won’t mind deepening their relationship with you as long as they are taken care of.
