I'm at Queens Hospital I noticed the 4G LTE signal kept bouncing from 2 bars to no signal then to full bars. I noticed that at work in Waikiki the other day too but I didn't think of opening LTE discovery app. so I believe T-Mobile is still testing band 12 here. Hopefully, real soon it will be unleashed on Oahu.
This says Band 13

Here is lower 700mhz bandwidth
That actually reads Band 12

More reason to come to Honolulu

Second location on the far east tip of Honolulu. This is an area that was a real sore thumb for T-Mobile in Honolulu. But not anymore I m surprised to see full bars band 12 deployed here. Just this past summer there was only weak 4 g hspa here. I guess the 700mhz roll out is still continuing in Hawaii.
