Working with Smartphones?

Hi guys,
I'm searching for a long Time for a solution to Work with
my Smartphones. There are a lot of problems I have when I try to do something with my smartphone.
First the problem with the ressources. The mobile data if I surf and do some work increase so much
that get throttled in a short time. Second one, most websites dont work on mobile phones.
3. The speed of copy/paste files or the moving and saving of files is even lower as working with the pc.
So now come my quedtion:
Do you have any software, tips or other stuff for me to make working with my smartphone easier?

It depends what you're doing. Normally I just use my phone for emails when I'm out. It might be worth investing in a laptop if you're away from your desk a lot. There are always wifi hotspots available if you're worried about mobile data costs.

I also have this problems as i am travelling much and working some. I always used my laptop fpr ebanking and writing but nowaday i make do with a small windows tablet with Mobile Data where i can connect a mouse/keyboard and use all the might of windows... It's not perfect but works and i can carry it with me all the time...
