Preparing for my trip to Sziget, I was wondering what the cheapest prepaid data sim cards would be Hungary has to offer. I checked the Prepaid Data Sim Wikia and was planning on buying Magyar Telekom's Domino Quick starter pack with 1290HUF (~4 euro) credit on it to get the Netplusz L data package for 1GB, which should be sufficient for a week. Or might there be a better deal out there I could make use of?
On a side note, we would be coming from Belgium, driving through Germany, Czech Republic, Poland, Slovakia and Austria. So unless someone could offer a better alternative that could be used in all countries, we would just wait and get the Hungarian sim card.
