In Reply to: prefix for int'l calls from bali sim posted by Randsurfer on Wednesday, 1. June 2011 at 05:19 Bali Time:
I used the prefix 01017 with my Simpati sim card.
A call to Thailand was less than rp1000/minute.
I'm guessing that is about 1/8 the cost of calling directly.
I haven't yet tried calling to USA.. When I do that I will report the data.
Very happy with these results. thanks everyone.
