t-mobile carlyT-Mobile on Wednesday announced it has doubled the theoretical speeds of its 4G network in 56 additional markets to 42Mbps. Cities such as Boston, Baltimore, and Washington D.C. are among those getting a bump.

The announcement feels a slightly premature as T-Mobile has no phones available yet to support this network upgrade. However, the T-Mobile Rocket 3.0 USB modem can take advantage of these high speed data improvements. Additionally, T-Mobile has indicated a phone that can take advantage of these kinds of speeds will be out “later this year.”

The company said more customers are demanding more have been vigorously consuming video via there phones and the upgrade will help support that.

“Video streaming on T-Mobile’s network has more than tripled over the last year, and consumer demand for access to rich mobile content from anywhere continues to grow,” said Neville Ray, chief technology officer for T-Mobile USA, in a statement.

The addition of 56 more markets to 42Mbps data speeds makes a total of 152 markets with these incredible-but-untested data speeds. T-Mobile says the 152 markets cover 170 million Americans.
