I am searching for the right answer to internet and cell phone signal on the road. I have a iPhone 5S . Just got back from 9 weeks in FL. For the entire 9 weeks, except for 2 weeks I had little if ANY data or cell phone service using AT&T. I camped near Sarasota and Bradenton area, Mayakka River and Lake Manatee. Lake Manatee gave me one bar, mostly at night otherwise nothing. Mayakka River gave me nothing. I did use a consessionaire's WIFI hotspot everyday.
Camping in Mantee Springs near Chiefland FL gave me nothing while in the campground. St. George Island State Park gave me one bar sometimes depending on the weather conditions and not consistant enough to finish a phone call. St Joe Peninsula State Park gave me 1 or 2 bars with LTE data... I was a happy camper there.
I used my phone with and without my protective case... without which the signal improved a little bit. Data and signal would work sometimes if I set the phone down on a coffee cup, but would be gone within 5 seconds when I picked up the phone... telling me the signal must have been very weak.
I am about to look into Verizon service and giving up on AT&T. On the other hand I am also thinking of adding a Wilson cell amplifier.
Wilson 460103 DB Pro 4G Yagi Amplifier Kit | +65dB Gain
Anyone have opinions on ATT or Verizon in state parks outside the suburbs and other somewhat remote areas? Or does the add-on amp make more sense?
