Here's my experience using DIGI's mobile phone roaming service in Indonesia.
Get this. DIGI prepaid does not support SMS roaming!!
I felt isolated as I can't even message my loved ones in Malaysia while
my friends using 012 in Indonesia enjoyed the facility to SMS back to Malaysia.
I've been happy with DIGI so far as I have used it's GPRS services to
blog from my mobile phone as well as post pictures direct to my blog (from phone too!).
Anyway, lesson learnt. Next time I'll get a 012 prepaid (temporary) when I go over again.
Oh should add that I can receive SMS in Jakarta from Malaysia but I cannot send any SMS from Jakarta.
