Prepaid TravelSIM

Today I purchased a Prepaid TravelSIM card from the Australia Post Office… Once activated I will then contact them to add the data option so that where ever we go we will have constant access to our families if need be… It will also give us access to maps and apps on my mobile so if we need directions, get lost or need to find transport timetables, we will also have access to our emails which will be our main contact point as I am told that Facebook gobbles data like crazy, so we might upload images to Facebook and leave posts but me may not reply to them, only if we have wifi…
