Finland, and I pay about 18-20€/month
Plan costs 14.50€/month and the rest is usage.
Plan Includes:
calls/texts 0.066€min/ea
unlimited 3G, both data and speed (15/5Mbps)
MultiSIM service + USB 3G-modem
I normally don't support the 24 month contract ideas but this was too good to pass up, before I had 384Kbps data package and paid about 14€/month with useage. I must however admit that I am a bad customer, making a couple of minutes of calls, sending a few texts and using up to 1GB of data a week, unless i am away from home when i can use up to 1GB/day.
