yes, it is not unlimited, but its really hard to hit 50gb a
month. an average user who surfs the net, watches videos, download
stuff.etc would have trouble using 20gb. anyway to make sure the is
always a data calculator so you can track your data usage.
the speed is acceptable and hardly any disconnection. much
better than starhub. I also feel that singtel has the best
coverage.
Im not that use but 4mbps shouldn't be a problem.
