Misleading. You didn't do five minutes of research.
Singtel (the most expensive telco) has multiple plans for visitors (100GB for $12 + 500mins talk + 1GB roaming + $3 to spend on public transport). If you want prepaid month to month, it's still nowhere in the stratosphere of $10/GB.
Also 4G coverage is virtually 100%, buildings and Faraday cages aside. (source: living in Singapore for 10 years, through 3G to 4G migration)
