Had we taken the time to document the differences, we could have done extensive research for this post because we had Casey's AT&T iPhone and my Verizon iPhone side-by-side in a lot of the boating areas mentioned in this post. Do you know that Johnny Cash song, "I've Been Everywhere"? I feel like that's us! We haven't quite been everywhere yet but we are sure working on it! By the end of 2013, we will have spent over 8 months on the boat this year (either on the water or 'boater-homing" on the way to/from the water).
Last year we boated in the San Juan's for 2 weeks, British Columbia waters/Broughtons for 4 weeks, and Lake Powell for 3 weeks. And we drove across the country and then down Skyline Drive and the Blue Ridge Parkway.
This spring, we boated in the Everglades (on a friend's boat), and then trailered our boat across the country (with a side trip to Hawaii for 2 weeks) to Prince Rupert, BC where we launched and then travelled 1985 miles on Alaska's inside passage over 3 months. Then trailered home a different route. The total just for that one trip was 16,268 miles, including the 1985 boating miles on the inside passage. We are currently on the St. John's River in Florida.
Had we kept a phone journal, comparing data signals in each area, we could have provided some great information here! But we didn't. :-( We did notice many times that one phone had coverage and the other didn't...but one service did not consistently win out over the other.
I originally chose Verizon because I lived in neighborhood in Southeast Georgia where that was the ONLY service that had a signal. Earlier this year, we thought about changing my Verizon phone to Casey's AT&T plan to save some money but we decided to keep both services specifically to give us a "safety cushion" for our Alaska trip...hopefully if one failed, the other would work. And that plan worked well. There were times when one service was clearly stronger than the other, times when one phone had NO service and the other did, and many times ... probably majority of the time ... when neither had service. But like I said, which service had coverage varied and there was no clear victor.
Now that our Alaskan wilderness adventure is safely over, we will probably convert my Verizon Phone to Casey's AT&T plan to save $$$. As far as safety, we have the VHF radio, our SPOT, and we will still have Verizon on Casey's iPad when we choose to make the data plan active (you can't talk on it but you can send text messages and e-mails). We are both grandfathered into unlimited data plans and we'll see what we can do to keep that going.
I wonder how many years it will be before the lower 48 has complete cell coverage....10? 20? And free wi-fi everywhere.
