It's the 10 gig per line tether/Wi-Fi that is going to hinder people
Not the 22 gig phone limit LTE data
Most RV users want data for their tablets, iPads, pc's, via Wi-Fi
To watch much video , users will need to stream it on the phone, where certain ( unannounced) services will be free use
I haven't seen anything saying which HD video services, is in this free bracket
And if you use a non-included service like sling box, then you will be using that 10 gig, if Wi-Fi tethered, or the 22 gig IF casting from the phone to the tv
Information and planning is critical , before switching v plans
The really heavy data users, could get stung by this 10 gig TETHER limit, those that do large amounts of work from the RV large documents, IT work, video upload
Those will need to get multiple lines if they wish to maintain data speed, those are the people who will need 4 lines and swap out SIM CARDS
