I got my MiFi 4G LTE last Friday. I knew that 4G is not available at my house. However, according to the coverage map, I should be able to get it in New Carrollton. Modem Diagnostics states that there is no signal.
I went to the Verizon store in Lahnam (which is in the fringe area) where I saw a Samsung hotspot with a 4G signal. The customer service rep took my battery out and plugged my box in and it got 4G (at least the pink light turned green). I went outside and tested the speed using my iPad and got very slow speeds 1.35 down and .40 up. Shortly thereafter it went back to 3G. The office building where I work is at least 1/2 mile away from the fringe area.
Today, I drove several miles towards, DC and still couldn't get 4G. I will try to drive into DC this weekend to see what the results are. I would hate to return my MiFi, but there is no use paying $50/month when I won't use 5gb of data. I can pay less a month for my old MiFi 2200 and get the same data rate. Are there any success stories in PG?
