Who I have the same questioned this topic

I am currently signed up for the Verizon TravelPass for the special daily rate in Canada.  The problem is when I travel to Canada I am frequently right across the border on the Canadian side.  The problem is in this area the Verizon signal from the US side is very weak and unusable but remains active on the phone.  If I move a few blocks away from the border where the Verizon signal is not present the roaming works fine.  I have tried changing the various options associated to roaming and networks. without any resolution.
