I was in Croatia in June and used VIP with my iPhone - worked great.
Anyway, if anyone wants it I have a 75 kn credit for VIP that I never used. I have the code you need to redeem it - just send me a private message and I'll give it to the first person who asks.

Update: The credit has been claimed.

T-mobile
 

I am going to Croatia on holiday the upcoming summer, and would like to buy a sim-card for the internet before I arrive in Croatia. I have tried on your web site https://www.hrvatskitelekom.hr/, but apparently they don’t deliver sim-cards outside Croatia. Where can I buy the internet start pack online? On Simpa - ?tima SVIMA

For how long time will the sim-card (phone number) be alive if I don’t top up the account?

How do I activate and especially deactivate the internet option?

Regards
