However if you are a T-Mobile customer, it seems that you won’t need to worry about it, at least for now because according to the company’s CFO Braxton Carter, he told CNET that T-Mobile has no plans to raise the prices of their unlimited plans. According to Carter, “We’re not pursuing a monetization path. The benefits of creating more subscribers outweigh the shorter term benefit of tweaking (average revenue per user).”
Of course this doesn’t mean that prices will stay fixed forever, but at least for now T-Mobile customers can rest easy knowing that at least in the near future, the carrier will not be hiking their prices (yet). T-Mobile also revealed that for Q2 2018, they have managed to add more than 1 million customers, making it the 21st straight quarter that they have managed to do so.
Based on this, it seems like whatever the carrier is doing, they are doing it right and would have no reason to change up the formula.
