It seems that all telcos are now focused on providing shared data for roaming in neighbouring countries and increased allocation for other countries.
hi! by Singtel just improved it’s plan with more data. The 3 plans comes with shared data across Singapore, Malaysia, Indonesia, Thailand and Hong Kong.
The plans also comes with APAC Roaming with the $13 plan throwing in a 18 GB APAC + China + S Korea + Japan roam.
All 3 plans comes with 3GB and 8 GB of international data roam in 60 territories. and various IDD minutes.
The advantage of these plans is that unused data, roaming data, IDD minutes can be rollover and auto stack for up to 6 mths.
Save $2 when you port-in from another telco.

While these plans are very similar to what SIMBA, eight are offering, the down side is that it doesn’t provide voice roaming.
So which plan will you go for?
