It goes hand in hand, Internet helps socializing too so can't say it doesnt matter. When you change to new environment it takes time to adjust and socialize for some people, So you still try to be in contact with your old friends and acquaintances and internet does that job, once you're Comfortable enough in your new surroundings, you can deviate most of that internet time to the new people.
Plus, internet is not just for timepass or leisure or socializing, Our jobs, education and basically most of the activities partially depend on internet, in one way or another. If you ask me how much time i spend on internet, i could say all the time, except my sleep and all the basic lifestyle stuff, and thats because i got 24x7 internet in my mobile.
But that doesnt mean i don't have a life outside internet, ofc i do, i got a heck lotta friends to attend. Its just that my mood is the governing factor if i want to lie on my bed or go out and do stuff.
