The internet usage is not a problem, its not
very much.
The problem is speed, I took mine in a caravan
last summer, 3 network had good coverage.
T mobile was hit and miss.
But the speed seemed to be a bit too slow
and I got glitching. The channels cleared
but the sound kept stuttering and picture
glitched as the data came through.
4G is out this year though so I will
have another pop at it this summer.
It wasn't that far off last year
but I'm pretty sure it was down to speed.
