In Reply to: anyone tried Travelsim phone card - am posted by nyonya on Thursday, 28. June 2012 at 16:48 Bali Time:
I used one of these cards on a recent trip to USA and Canada.
It is very complicated and more expensive than a Bali sim. It's also confusing for anyone wanting to contact you on the free or cheap rates. I wouldn't even consider it for Bali.
Better option - download Viber if you can on your phone and use this for free texts or calls. All you need is wifi access.
