Most places I camp there is no Wi-Fi
I stay at an RV resort . Once OR twice a year
State parks beaches national forests, don't offer Wi-Fi
Our minimal home base, no Wi-Fi
My cell phone has been my internet for many years
I now also have the jetpack on Verizon from the Huntsville school system
I can spend hours doing email and web surfing and only use a 3gig a month
But start watching funny dog videos on YouTube OR Facebook etc..
And it shoots up, watch a Netflix movie and that's it, it's all gone and I would be on overage use/charges
But I have an old unlimited plan on my phone, and a new unlimited plan with the jetpack
New unlimited plans are almost non_existent in the consumer market
If you Never watch video Netflix YouTube Amazon our HuLu at home then you won't miss it when you go on the road,
But if you do..then you want as much data as you can get..You want unlimited
For those that only go out for weekend our short trips, yeah you can do without no problem, but being on the road and staying connected the same as home is not a make do weekend trip
Everybody's circumstances are different
And the OP might be working on his 8 month trip, just like many full timers work while traveling, being a telecommuter means data is a must have
