Roaming using my home country provider will be too much to bear for. What wlll be the most cost effective data sim card solution? I suppose one set of sim for Australia and another set for Asian countries? What specific sim provider would you recommend? I had poor experience with a particular mobile provider in Hong Kong few years ago (a store refused to sell sim cards)
Australia
Hong Kong
China
Singapore
Malaysia
Take a look at these two threads in the Travel Technology forum, a portion of FT that's specifically dedicated to technology for travel:
eSIM thread
and
List of Prepaid SIM threads (country-specific and multi-country)
Those might get you started in the right direction.
