You posted a little while back about renting or purchasing a cheap mobile to use when in Bali.
If you are still looking for one, I came across this in the Bali advertiser classifieds.
"HP Siemens with number and charger. Cheap price, only Rp. 300.000, ready to use here in Bali, owner leaving. Sanur, call 081558321215"
I think that's about US $30. Pretty cheap if it's still available!
