I have a Heyah sim card. How can i use 3g network in Poland?

Hello guys.
I have a android smartphone and use Heyah sim card.
Actually I wanna use 3g network in order to use internet.
In description, I need to press USSD code but I couldn't do that.
Because when i press USSD code like a *120*12#, it didn't work.
I think my phone is not supported to do that.
So I wanna find another way.
How can i do that?
Is there a way to set up by using Heyah website?
I can't find correct website to set up because I don't understand in Polish.
Plz let me know about that.
I'm looking forward to reply.
Thanks.

Hello,

I get tons of spam and advertising SMS from Heyah but do not speak Polish enough to find out how I could deactivate the delivery of these messages.

Could anybody help me out?

Thanks!

Call *2222 or 888002222 from your heyah phone and ask to switch it off (1 zł / min). Somone should speak English there.

Incredible. First I have to call a paid hotline to disable it?

What a crappy provider...

Try instructions provided on their website. What kind of phone do you have? For some models exist a possibility of auto setup. Check this:
