Poland prepaid data

[ms93]

APN: heyah.pl
User: Heyah.pl (on www there's Heyah.pl with uppercase H, but it may be a mistake)
Password: heyah

I think this user is a big mistake. I use only "heyah" in daily use and it works. Also configuration SMS from their website contains user "heyah".
So:
APN: heyah.pl
user: heyah
pass: heyah
