You can buy Lyco sim cards in cities. They are designed specifically for international calls. Most people who use them have an ordinary sim as well. I reccomend Play.
Is it possible to purchase pay as you go sims with data bundles if visiting for a couple of weeks. Using data on my phone with my contract would be very expensive. I want to make a few international calls back to the uk, but I'd like easy access to data wherever I go, particularly maps. Can you just go into a phone shop and buy a payg sim (I'm not even sure you can do that in the UK)with a data bundle?
[Moved from]: What is the cheapest way to call to the Netherlands from Poland?
I would like to make a long call to The Netherlands. I have a cell phone (with T-mobile Tak Tak) and I don't mind going to a place / building in Kraków to call, if I have at least some privacy there.
Could anybody please advice, and give a price indication as well.
Choose any you want to for example Play, and download Vippie on your phone, ask your friends for abroad to download it too, find wifi net and call them for free:)
