While traveling this week I get crally service on my S3. If I get 4G I only get 1 or 2 bars. Most of the time I get no service at all. I can sit in the same spot and watch it change back and forth between 4G and no service hitting all possible levels between. People sitting near me with Verizon but different phones get 4G with 4 bars but I get none. They are on their home network but my home is on the other side of the country Is there a setting or something that boosts my connection level when traveling? I'm not roaming. This is all on Verizon 's network.
