It's normal to switch between 3G and H/H+, Celcom is using Fast Dormancy technology for their 3G network, and this technology is said to be able to save battery by switching to 3G when network is in idle mode.

Just want to share

If using Iphone, this can happen. Not sure which iOS but I think its the iOS9 and above. The feature is called Wifi assist. If Android than it shouldn't happen.

Here's a link Wifi Assist

Quoted from the website.
"The feature quietly swaps your iPhone from a wifi connection to mobile data, if the device judges that your 3G or 4G will be the speediest of the two connections. It's designed to stop endless load times when connected to a sluggish wifi hotspot or home network – but it can quickly burn through your mobile data, especially if you don't have an unlimited plan."

Also take a look at settings for each App. Some use mobile date in background.

Android has more control over roaming settings. I wished iOS can improve on this, better still if there is a separate permission for app's mobile data usage when roaming.

Here in Bukit Antarabangsa and Ampang area, 4G always full bar

Send "Bal Status" to 28882

If you move from other telco which is not yet due bill cycle...how u settle the amount before the cut-over?

From my past experience, it will be prorated and they will send you a bill/statement.

They will send you a prorated bill and if you have deposit with them they will issue you a cheque.

pro-rated amount would be charged & the bills posted to the users.

any deposits would be return later by cheque

celcom kakis...wanna ask...did you guys get 5% rebate for auto-billing on the 1st month?

I did not get mine...called CS they said only 2nd month onwards will get it... betul ka?

Technically speaking, u get ur 1st month rebate on the 2nd month bill. So no, CS gave u the wrong answer.

ok means 2nd month rebate will be on the 3rd month billing? correct?

Yes, the cycle goes on & on.

Btw, do they charge u for check balance sms?

it is FOC...u can send BAL STATUS to 28882 everyday every hour

they dont have official apps to monitor usage like maxis?

That's the thing, even uMobile has ocs app, Celcom has none.
Guess we just have to live with SMS balance query till they develop the app.

my guess they are coming with one, an app for prepaid user is coming soon first

I hope your guess is right

I am hoping for this too, for prepaid is confirmed - Celcom Bakal Memperkenalkan Aplikasi Xpax Rasmi Tidak Lama Lagi
