They advertise "European Roaming" tariffs at reasonable rates, you need to note that this is not Europe wide. They charged £5.22/MByte (that's MEGAByte not Gigabyte ... i.e. about 2 minutes on google maps) for data. 8 Mbytes for £42, within a European country not listed under their "European Roaming" tariff.

Just let that sink in, that's over £5000 for a Gigabyte of data.

Complete rip-off, and, false advertising, it's not European. Service provider is not suitable for international travellers.
