The day I bought my Unite wireless hotspot, I noticed my Samsung Note2 started showing LTE. When I visited the East Bay (Pleasanton, Dublin, San Ramon) or when I went to Modesto, my phone would show LTE, but when I was in Tracy (hometown), the LTE indicator was not active. I assumed that it must have been a coincidence that LTE came online the same day I got the hotspot. But in speaking to a sales clerk at the ATT store, they said that LTE is not automatically given to phones, even if they are capable of it. That doesn't sound right seeing as I did get it in other towns, but he claimed that when I upgraded to the new family-shared data plan (free voice & text but metered data), they activated LTE. That seems a bit deviously shrewd on ATT's part if that is true.
