T-Mobile has always been criticized for its performance inside buildings, but according to a senior T-Mobile official, this issue would be resolved soon by the addition of 600MHz spectrum.
According to the news, T-Mobile will add Samsung and LG phones to its lines up with 600MHz capability. Although not confirmed the expectations are that Samsung Galaxy Note 8 and the LG V30 will be the phones. T-Mobile is expecting to capture a bigger share of the market by this launch in collaboration with Samsung and LG phones offering. T-Mobile has been in the news recently for market expansion and a possible merger with Sprint. I guess time will tell if this launch will help beat the competition or not.
