Alaska Road trip, 2019

We will be making the trip in May 2019 also from Ohio. I have a 2017 mile post I don't know if I should update it or not I don't know how much changes up there. Information found on this form is in valuable I have bookmarked several sites that are here. Cell phone service up there is a little confusing. we went to eastern Canada, Prince Edward Island and Nova Scotia last year and our AT&T cell phone with unlimited service worked perfectly no extra charges at all. It automatically switched to Bell, Rogers or Telus depending on where we were. Was abltstream Cleveland Indians games from very remote areas.. We are switching over to Verizon however and was wondering if it will be the same thing. I have read conflicting reports on Verizon service on this forum however if I am reading it right I should not have a problem.
If anyone starts at rollcall 2019 Alaska Count me in !!!!
