Good mobile plan deal

The most exciting news for me this month is that I finally changed my mobile plan to a SIM-only plan and guess what, it only costs $20 a month!

So my current plan is a corporate contract: 

$32.65 per month, 

6GB 200 mins talk time.

It had expired last year December, and earlier this month Singtel sent me a corporate promotion: 

$20 per month, 

20GB 700min talk time (really?? 20GB? isn't that too excessive??)

Tell me, logically, who is able to resist such a good deal. More data, more talk time (not that I will use) and so much cheaper? I think this is the cheapest plan I had since my first Singtel Classic plan 18 years ago. 

I love saving money.
