Mind to share your experience on their network.
Im having hard time finding Celcom fiber review when I deciding isp to use last time.
Been using for 3 months now, I will do some review, to help anyone researching options for their next ISP. Things change from time to time. Be sure to take note of my post date.
Package I use is 300mb, RM140 not include tax. Router I use is my own Asus RT-AC67U.
This review does not represent the entire scene. It only covers my personal experience, usage, and issues encountered as well opinions.
ContractThis is the best thing about Celcom.
- RM500 flat termination fee.
- 2 years contract, you can upgrade or downgrade within contract period without forced renewal (aka no reset). Downgrade however is charged RM50 per request.
Service quality- Router provided currently is TP-Link AX10. Not the best, but as a stock router provided free it's one of the best compared to other ISP.
- Upgrade/downgrade speed via phone call. No extra steps. New speed will reflect within 24 hours (need to disconnect and reconnect router).
- Online billing need to go through shitty customer portal interface. Set auto billing to save you from having to use that cancer portal every months.
SupportSupport is mixed bag. For fiber customer, your support is on separate framework from mobile.
You will be limited to phone and counter support (boomer's heaven). No email, no whatsapp, no live chat, no ticket whatsoever. 50 cent charge to speak to customer service person via 1111 support line.
On the positive side, you are served by a separate team of high quality phone support. Request to speak with CS in person will be connected almost immediately most of time and the guy answering is competent.
Second tier support that dealing with customer network problem is not very pro.
One time I had network problem - my connection to LA via HE get blackholed in HK for god knows why.
Contacted phone support, the issue was delegated to internal network guy. He insisted to send technician to home to check on my router although I explained many times this is upstream problem beyond his scope, and there is nothing he can do. He needs to forward it to higher tier routing/bgp guy. But no. He still insists on investigating it himself for 2 weeks, asking me to check if the connection is fixed from time to time, and asking unrelated questions where he suspected the problem might be caused by my previous public IP switch. But ofc nothing gets fixed lah. One day he finally gave up and forwarded the issue to routing/bgp guy. Couple of tracert and mtr later, the problem fixed the next day

.
Ignoring that issue with actual problem, the entire support process itself was outstanding. The person in charge would call me from time to time to report the progress. After the problem was solved, the CS that initially filed my issue called again to confirm everything is solved and asking my permission to finally close the case.
From what I see, the entire customer service is built around assuming all the customers have exceptionally low tech literacy by default.
Their stock routers login is assigned as limited users (full admin login is available but not given by installer). They will send technician to home for smallest task like changing PPP username or inspecting router configuration issues.
Its good for majority of users. But for tech savvy people this gets annoying quick.
Network quality- Private IP by default, Public IP available for all plan on request (for now). Just call CS and tell them you want public IP. No drama. No question asked. But they insist on sending technician home to set up a new router configuration.
- For public IP, you are always assigned in a fixed /24 pool, which is so classy
- No IPv6. But not quite. Technically you are still assigned /64 address in wan interface, but the implementation is currently broken, and the prefix is not delegated to LAN so it's basically not usable. If you use Asus router or any router that supports 6in4 tunnel, you can use good 'ol HE's tunnelbroker to get ipv6 and the performance is surprisingly good nowadays.
- Celcom is using different routing than TM. Not good or bad thing, that's just how ISP work lah.
- One notable case is, Celcom is using different undersea cable than TM and not directly affected by current cable fault in HK currently affecting Unifi, and to some extent Digi/Time/Maxis.
- Ping to SG is typically around 13ms, worse than TM's 10ms.
- Celcom generally has better connectivity to European and East Asian datacenters.
- Jitters are minimal. I rarely experience any ping spikes when playing games (mostly bf1 and PoE) during peak hours.
Speedtest (12/1/2022):- Server selection based on services/dc that I use the most, or major ISP in biggest cities.
- Test made fom my location in Klang, using speedtest-cli 3 times, with median speed result selected.
