Help! Downloading while driving-your experiences?

As I posted elsewhere, when I got a Verizon 3G iPad, we couldn't effectively download stuff while driving on I-15 from LA to Vegas to Utah. My kid was surfing, but to actually download a complete app etc didn't work. Just very slow or maybe signal dropouts.

Is this normal? Or is mine maybe defective, as my friend wondered?

From my memory of I-15 LA to Vegas..... mountains, desert, long distances between cell towers. It's a wonder you can get a decent signal at all once you leave Barstow. So yes, it's normal.

I've got a Verizon 4G iPad (3rd generation) here in the Dallas - Fort Worth area where there are numerous cell towers and good LTE reception. I still get drop outs once in awhile depending on where I am at the moment.

I have that issue in my area with my verizon 4s and ipad 2 its probably just the location
