T-Mobile (NASDAQ:TMUS) kept its promise to release its 5G network but, rather than launching December 6th as they previously announced the network is actually live today.  T-Mobile is the 3rd largest nationwide wireless carrier in the United States with a history of over 25 quarters of adding 1 million net users of the service.  The company is also looking to complete its acquisition of rival provider Sprint (NYSE:S) in early 2020. While T-Mobile opened up its 5G network today users on Metro by T-Mobile will still need to wait until December 6th to access the new 5G network.  Unfortunately though, for at least the majority of users, to access this new network you will need to purchase a 5G enabled phone. 

Currently, there are only two phones that work with the new network standard and those are the OnePlus 7T Pro 5g McLaren Edition or the Samsung Galaxy Note 10+ 5G and these are only available on pre-order.  So until you have either of these phones you won’t be able to experience the new speeds on offer from the T-Mobile. T-Mobile is also planning to have 15 new phones that are compatible with the 5G network coming out in 2020. If you are on more of a budget it might be a better idea to go ahead and wait out the early release of the network and for the company to complete the next round of upgrades.  One other wrinkle is that the coverage may not be available in your area, so it would be a good idea to review the 5G coverage map before purchasing a new device.
