I haven't started my international roaming yet. Can you receive text messages in Indonesia?

I can't get it. There is no signal in Indonesia.

Buying a card in Indonesia is very cheap, so throw it away when you leave. Indosat's mentari card has a good signal, and it's also cheap to call China. 500 guilders per minute, about 40 cents. Dial 0 10 16 before the number. You can also send and receive short messages from China.
