Life / Which is the best Polish mobile phone provider for family use (4 phones)? [4]

My family back home is using T-Mobile back home! Here you find all the info in English! They are using mainly prepaid phones or a mix with postpaid (not sure) cause they say its easier to controll the cost of their Kids and easy to top up mobile credit.

Best of luck with the move!
