SINGAPORE - Mobile users are getting good data download speeds, according to an official app to gauge users' mobile data experience on 3G and 4G networks.

Data collected from 4,000 mobile users across the three local telcos from October last year over six months show that 4G speeds are typically between 5.1Mbps and 42.4Mbps, good enough for social networking, video streaming and online gaming.

These speeds are about five times faster than data speeds over Singtel, StarHub and M1's 3G mobile networks.

The data is collected by an app, MyConnection SG (available on both iOS and Android), released in October last year by the Infocomm Development Authority (IDA). These findings were announced today at the opening of the week-long Infocomm Media Business Exchange (imbX) trade show at Marina Bay Sands.

"The data collected through this pilot will increase the transparency of information to help consumers to make informed choices on their mobile plans and improve user experience," said Dr Yaacob Ibrahim, Minister for Communications and Information in his opening speech.

"MyConnection SG app is a model of how continuous improvement will help us achieve our smart nation vision."

IDA's findings also show that StarHub users experienced the greatest lag to establish a mobile data connection, followed by users on Singtel and M1's networks. Some users of the app also reported experiencing blind spots where they had no mobile connection in Tampines.

The pilot phase of the app will end this month, with its official launch slated for end 2015. IDA intends to publish its findings every six months.
