Hi, Yesterday I was reading Masayoshi Son, SoftBank, want a possible merge with T-Mobile. Now with Trump Administration looks like it could be approved and maybe he is going to start talks with T-Mobile. It could be cool if that occurs.
Here a map I create with Sprint and Open coverage. It could be like this or better I think.
The same image wit Sprint colors
And here if Sprint, Open & T-Mobile could be merged
I hope it could be possible in a near future.
This last image is all carriers coverage (with the map on their websites)
