I also using celcom this RM38 First basic package and I had a same issue with Celcom where no service in Enterprise 4 at TPM and Internet connection is only E at Setia Walk. And always receive sms notify me that I have missed calls.

My phone is showing "No service" now and my colleagues also having the same issue now.

Last year, I had an issue with 3G connection at Setia walk and I walked to the Blue Cube center at Setiawalk to ask why the connection is so bad. The staff replied that the network booster is broken and under maintenance at that area but until now the connection at Setiawalk is still really bad. I even called to the center and the technician said my setting is not correct and need to reset. I said why I have no issue when outside of setiawalk and no service at setiawalk. After the new setting which sent from the Celcom technician, the connection also still very bad.

I hope Celcom can see this message and do something about this to enhance their network not only widest, please make it strongest network also. Thanks.

Thanks for your advice. But I have no issue with Maxis. Why i port over because of the Maxis plan is too expensive.

I was at ground floor at Setia walk (Puchong) and Internet line was E only. Even in my landed house, the internet also E sometimes.

My office is located at 4th floor only and not other higher building that cover or block this area. If you say it cover by building and it will drop but why I go out from the building and everything is fine? And problem is, why it only happen few day at once and normally it was fine. It is frustrated if there is no service when I need to use the Internet. Now, once i switch on the mobile data, the line will drop. If no mobile data, then the line is fine.

If you said the signal tower is too far away, and this is thing that they need to enhance which add more signal tower to make it stronger.
