Looking for the best GPRS EU roaming prices
 

Hi,

I'm looking for the best GPRS roaming prices in EU. The new UK T-Mobile Euro Internet Booster offer looks very promising. I need sim cards to be used in car fleet management company. Cars travel all around Europe. Monthly data transfer in GPS tracker is very low around 10-20mb.
What service can you recommend? Monthly flat fee would be ideal

Thanks for your help

Regards,
Seb
