T-Mobile isn’t slowing down when it comes to its network upgrade. The upstart wireless carrier said on Thursday that it plans to add 4G LTE to its slower 2G network, adding coverage and speed to additional customers. The company also reiterated its intent to use the wireless spectrum it is acquiring from Verizon to further expand its coverage later this year. Oddly enough, T-Mobile also said it was taking legal action against Verizon in an effort to get it to stop using its network coverage map in its advertising, which T-Mobile argues is “cherry-picking” a single technology (LTE) to illustrate its superiority. T-Mobile has long claimed broader 4G coverage than what is depicted because it also factors its larger 4G HSPA+ network. “Verizon’s ink blots massively understate our coverage and don’t begin to represent the actual customer experience on T-Mobile’s network,” CEO John Legere said in a statement.
