I love the game but It keeps giving me network errors

I love catching, evolving, and battling with Pokémon but it always says my bag is full even if I get rid of stuff to get more space and I cant get gym badges because it keeps saying my bag is full and sometimes when I try to catch Pokémon or go to the gym or pokéstop it keeps saying network error. I still really like the game.
