People downvoting this are not seeing the whole picture. Yes, 4 competitors is better than 3. The problem is that Sprint is no longer a competitor and is on a downward spiral. Without a massive cash injection, they no longer had a viable path to catch up. Their service is bad because they don’t have enough cash coming in to improve their infrastructure, and customers aren’t giving them cash because their service is bad. So they charge less, and get further behind.
T-mobile is the underdog. They are making a remarkable recovery and putting up a fight against VZW and ATT. But they still have coverage and congestion issues that are dealbreakers for many potential customers. They have already put pressure on VZW and ATT to lower prices and start bundling third party perks this year. Giving TMO an infrastructure and subscriber boost by allowing them to acquire Sprint is going to put a lot more pressure on the other two, especially once their 600mhz Band 71 rollout is done and consumers upgrade to newer chipsets that support it, essentially solving their infamous building penetration problems.
With Sprint’s assets and subscriber base, they’ll go from being the underdog to being a serious threat to both ATT and VZW. Instead of thinking that we went from 4 players to 3, think of it as though we went from 2 players to 3.
Edit: Actually it’s better than that. The approval requires TMO to provide Dish with spectrum access for 5 years and operate as an MVNO while Dish builds out it’s own nationwide 5G network to go independent. That means this deal puts 4 players in the market, as opposed to 2.75 players if it was blocked.
