Hi fruitie, I'm Lee, having issue in:

1) Taman Sri Bintang, Kepong - 3.187333, 101.645903
Two month ago, indoor 4G reception is good, 2G/3G mostly no signal, but since one month ago, 2G/3G/4G reception was bad, almost unable to connect.

2) Taman Amansiara, Selayang - 3.271878, 101.647423
3G shown connected with fullbar, but unable to make/receive call/data.

Called customer service before to do some troubleshooting but still doesn't help... Been tried with sim from another telco, both locations reception are fine.

Thanks!

Okay.. thank you very much... hope the problem will be solve..
Coz wish to stay with this plan 

Kenanga Apartment, Jalan Wawasan 2/3, Taman Wawasan, Puchong

Indoor cannot get 4G reception, mostly 3G or HSDPA, sometimes(not much) will drop to EDGE.
Biggest problem is always drop line, example I'm browsing internet on phone, suddenly disconnect from network(including normal line), need to wait 5-10 seconds then reconnect line and internet. Happens often which is dam annoying!

Thanks @fruitie

Really need help for this, my home

Taman Bukit Permai 2/3, Cheras - 3.105660 ; 101.759495

No line at all in my house area - cannot receive call, sms and also internet access.
Need to go out to the street only manage to get some connection.
Been complaint but somehow Celcom do not bother at all.
Really hope you can help on this..
Well, if they really dun do something - after the end of the contract.. for sure will MNP to other mobile. Even Umobile and Maxis can access 4G at my place but not celcom

Hi fruitie,

Thanks for the follow up...

It's been improved for:
2) Taman Amansiara, Selayang - 3.271878, 101.647423 - No more issue with 3G connection which is showing full signal but unable to call/data.

But issue still same for:
1) Taman Sri Bintang, Kepong - 3.187333, 101.645903 - Indoor reception still weak for 2G/3G/4G, tried another telco's with same phone, works just fine.
During July there was 4G connection in this area, but now seems no more.

That's all I've tested so far, hope it helps for futher improvement... thanks!

Wow glad to hear that, at least they are trying their best.
Thank you very much for your help!

Setiawalk, puchong.. Signal very weak. Sometime no signal at all..

Hello,

Issue Reported: Celcom coverage
Location: Taman Kundang Jaya (Kundang - In between Rawang and Sungai Buloh) 
GPS: 3.280998, 101.5317
Issue Details: My house consists of 2 Celcom postpaid users and both of us will have the same issue.
- Dropped calls in between
- 'Waterfall' sound during conversation and dropped calls subsequently
- When in 3G mode, data transfer is almost impossible
- LTE only will appear when I'm in the first floor of the house (double storey house)
- Line will be full but I will at times receive notifications saying I have missed calls from a few person. This is really frustrating

Thanks in advance for your help!
