Yes...and it's available in M1 and maybe other telcos...
But I'm not sure if it's the cheapest....I'm trying to find out
if calling oversea via a fixed line is still cheaper than even the
cheapest prepaid card.
Btw, whether it's prepaid card or regular mobile sub, the rate
is the same. For M1 at least.
Revert with your findings and say hi to your family for me!
Cheers...
