Been using Digi for the past 10+ years & decided to port to Celcom First Basic 38 (along with my sub + other lines, total of 4x lines converted).

And shock to realize that Celcom reception is terribly horribly BAD. Almost 80% of my daily reception is on 1-2 bars. And with such weak signal, data network is almost like handicap <cacat>. So regret that I made the wrong decision to port all my lines out to Celcom.

Drop calls, Zero reception, Dead/Snail data - are all I'm facing currently. Escalated to Celcom 3x times (3x case numbers), but said Tech Support going to contact me (not surprising that no one ever contact me after that). And what is the point of calling me for, it is not my line issue now, is the entire Celcom signal strength we're talking about.

Some may say it's the location I'm in. Well, I got 4x lines all together (use by 4 different people; in different locations; travelling around Klang Valley & PJ).  All encounter the same problem & having the same complaint.

Tried resetting network, signal  booster app, tried on different devices, speed test like crazy - all the same problem.
I am really hoping this to be temporary (but 2 weeks already), as the First Basic 38 is really a competitive plan that I wish to stay on for all my 4 lines to also reduce my monthly bills. However if things remain, then no choice but to pay a little more, than to hold a phone with ZERO reception. Impossible to have a phone that can't even dial out emergency.

Sharing with you the missed-calls record (with my cell/data network on).

Summary of all the issues after 1 month of usage:
- Whenever 3G/H+ received, phone network strength will show full bar. But 4G received, signal bar immediately drop to 1-2 bar.
- Data usually works outdoor (slow speed), but dead whenever goes indoor.
- Averagely 1-3 call drop every 5mins call.
- During calls, very often voice turn into some robotic/transformer like sound. Happened to different Celcom line (different devices).
- Delayed SMS received.
- Sometimes when you tried to end a call, it will keep auto-redial for no reason & refuse to end call. Happened to all my Celcom line (different devices "Samsung & Asus").
- Call connection is slow. Averagely took 7-9 secs to connect.
