T-Mobile users can connect to the Wireless@SG, the free wireless network via their SIM device while visiting Singapore over the next month. Local industry regulator IDA (Infocomm Development Authority) led a month-long trial involving LTA (Land Transport Authority), SDC (Sentosa Development Corporation) and local telcos Singtel and M1 for this access option. Both Singapore telcos prefer T-Mobile as their preferred US data roaming partners.
A registration is not required. Before automatically connecting to the network a one-time setup is required and users SIM card is used as credentials. There will be a total of 290 hotspots involved, specifically major MRT stations and Sentosa. Singtel is controlling the six major train stations including ChinaTown and Orchard. In order to power outdoor public Wi-Fi hotspots using solar energy on the island, Sentosa started a year-long trial this May. This deployment if determined to be feasible would be extended to other parts of the country said, IDA. The T-Mobile trial will take place in aggregation with the Wireless Broadband Alliance City Wi-Fi Roaming project according to IDA which is also applicable to the Singapore nationals who wish to visit San Francisco, San Jose, and New York.
The Singapore users have to download a configuration file and perform a one-time setup in order to initiate an automatic connection.
