lf affordable promo to use in travel

Hi, I will go to Pangasinan to work in a site project. However, I am having hard time in choosing what load promo is good to use while traveling? I'll be in a 5-hour bus trip so much better if I can use those time to be productive or just make myself comfortable by browsing the internet. For watching videos and such, so much better if it has an unli feature or something. Any recommendation?
