Advice for using laptop while tramping

Hi… Vodafone and three network are about the best for data!! I have Vodafone £24 a month and get 100 gb of data and unlimited calls and texts!! And I think three is unlimited internet never slows down but a little more expensive… dont go with giffgaff as when you use the 40gb the connection is very poor films just buffer and downloads take a year!! :wink:
