Today, the data roaming is extended to Indonesia. This time round, it’s partner network is Smarfren.
It runs on band 3 (1800 MHz), band 5 (850 “MHz) and band 40 (2300 MHz). Most of the smartphones should suppot these bands.
The data rate is capped at 1 Mbps which is quite decent for data roaming. The same set of outgoing call minutes applies. You can make calls back to Singapore directly with VoLTE TPG certified phones. Voice call to local numbers is not supported yet.
