Indeed.
My advice is to avoid SingTel if you are a new user as you will get the ONR.
For existing SingTel ONT users, I do advice to continue if you got no issues (eg: you are not into gaming, just want a stable connection). I sticking with SingTel myself since it is stable for me (long time user since Feb 2012).
As for those who need SingTel TV, take note you do not need to subscribe to SingTel Fibre in order to use SingTel TV. You can continue using your existing ISO.
My recommended ISP for new users is M1 and then Starhub.
