Savannah LTE is still hit or miss feast or famine. Garden City is for the most part FAST LTE along Highway 21. GREAT download speeds. Unfortunately, my house is in a 3g zone between 2 LTEs. Lots of trees, maybe it will get better this Winter like it was at the first of the year.
But, I must say that 3g speeds are much improved over a year ago. Possibly from the load going to LTE.
Overall the network upgrades have been great compared to a year ago.
