The 20% extra credit for using bitcoin - is it only a time limited promotion?
" Customers who use the bitcoin top-up service will also be rewarded with an extra 20% of calling credit
during the trial. "
-So thats a yes, limited time only. The bitcoin payment option can come quite handy, now if they would just offer that option in other counties of the world, and
add an option of sending credits from phone to phone, with a cashout option, there would be a whole new market for buying/selling bitcoin also
