amaysim’s unlimited international calls apply to ten countries – USA, UK, New Zealand, China, India, Hong Kong, Malaysia, Thailand, South Korea and Singapore. The higher-end plans add five hours of calls to an additional 12 countries to what is already a very sweet deal.
Amaysim uses the Optus mobile network, and cut a deal with them in 2015 to expand their coverage to take advantage of the advanced 4G Plus section of the network as well. That means fast data download
is yet another thing you don’t have to miss out on just because you choose prepaid.
