Re: How do I use international roaming and what are the costs
International roaming is enabled in Boost by default (you don't need to turn it on). To actually use it though, you need to get some Boost add on credit, on top of you normal unlimited credit. The rates differ by country, and the exact rates for each are the same as Telstra prepaid roaming rates (available on the Telstra website). Those rates use your add on credit only, and expire as per the add on credit schedule on the Boost site. Needless to say it is not cheap to roam and really any provider. Data is definitely not something you want to roam with (ie, $15 per MB). If needed while overseas, #111# still works to adding more add on credit.
