Apart from true 2.5gbps from ONT, i dont see how simba better than whizcom ?
CGNAT is especially the deal breaker, having sharing public ip address with others you will need to deal will gaming issue or block by some website. Some cloud hosting even do bandwidth control on single ip to prevent traffic hoarding. The worst thing for power user is you cant do port forwarding.
If your ip got ban, you cannot change it or do anything about it. .wait until ur session got rotated to next ip or it may not even happen.
The come billing, really quaterly or 1/2 year payment? u can see how much simba dont trust Singapore. lol
Are they scare you run off with their ONT ?
Then you will start seeing more page(behind cloudflare) with are you human because dosen of people access same server from same ip address is abnormal.
Then the ads, i got super annoy when when public address change, instead showing lazada or shopee, i am seeing online casino or private massage.
I would even pay more to avoid CGNAT at all cost.
The only accepted solution they provide ipv6 with ipv4 CGNAT, at least there is work around.
