Guys, wanna ask if someone use celcom on 3gs? currently i already jb my iphone which is on 3.0.1 firmware. one i got my iphone, straight i jailbreak and currently i have problem where sometimes the call will drop immediately right after 10-15secs call. 2nd call then ok already. is it jbreaking made my iphone crazy? i also install sbsetting where i disable edge and 3g there.

called celcom cs and they told me everything was back to normal. no network failure whatsoever. help! quite irritating also when the call dropped.

the connection drop whenever i call a person. if i had an incoming call, nothing happen.

I don't really know if it was Celcom or iPhone. I receive my phone on 24th September, evening. By that time, Celcom network infrastructure having problem where you can't call in and out. After Celcom's network back to normal, then started having this kind of problem. The best part is, not all call having the dropped connection.

I remembered when I was using iPhone 2G where Celcom simcard does not support for it. So I opt to use Maxis instead. That time there was a problem with 128k Celcom simcard.

I will monitor this time to time. FYI, I already uninstall SBSetting but to no avail. Enable edge and 3G also useless, will drop sometimes.

@myhemay, did you try to swap the simcard with the old 64k? If I remember correctly when I'm using 2G, there is one forumer here told that if you want to use Celcom with 2G, have to swap to 64k simcard. Have you check whether your friend celcom simcard using the 64 or 128k?

* I'm not really sure whether it is 64k or 32k. hehe

I will stick with Celcom. I'm going to centre and ask if they have the 64k simcard.

Meaning that if change to 64K simcard, cannot use 3G at all right?

AFAIK, 64k sim is using 2G technology whilst 128k is using USIM (3G) tech?

I had that problem before, I just renew the dhcp and everything goes back to normal.

Try to check whether you can surf using Safari? If yes, meaning there is something problem with youtube app. If not, try to renew your IP Address and check what kind of IP you get. Usually for LAN IP will be 192.168.X.X or 10.0.X.X.

When a WiFi device couldn't get any DHCP from WiFi modem/router, the device itself will auto assign "self-ip" and usually the ip starts with 169.X.X.X.

Say I am using my iPhone and I have Linksys wifi router with DHCP enable at home. When I turn on iphone wifi and connect to linksys but linksys refuse to give ip. Usually when a wifi router failed to give ip because of "hang" etc.

So because of my iPhone waiting so long to get the IP, then my iPhone itself will assign its own ip and that is 169.X.X.X

Added on September 30, 2009, 9:56 pmHi bro,

I think I found my own solution to my own problem. Previously I mention that I JB right I got my iPhone right.
Then I started to install SBSetting as well to disable EDGE/3G because I saw some of our forummer here got lotsa bill for data usage and I'm afraid I will be like that too.

Just now, I try to troubleshoot by enable both EDGE and 3G and surprisingly, no drop call. Disable 3G only also no drop call, but will drop if both disable.
You might wanna give a try. So the conclusion of this, maybe the voice layer needs either edge or 3g?

I think so. Because everywhere I tried, will get disconnected if I disable both EDGE and 3G.
So as for now, the connection is superb, either both on or just EDGE on.

I'm talking this if you're using Celcom by the way. Other forumer using Maxis while both settings off, seems OK.

Must be your YouTube app problem? As for iTunes, I can't use it either cause it is not support in Malaysia, some sort of that.
On prepaid, I think you have to disable EDGE/3G. Got thread about this.

Hi guys,

Been searching in the forum but can't get accurate answer. By the way, as you all know in certain thread here, got some of us had a problem with iPhone 3.0/3.01 with Celcom 3G with call dropped and call failed. Anyone that encounter this problem have the solution?

iPhone 3GS 3.0.1
Jailbreak with redsn0w 0.8
Tried to enable/disable 3G, EDGE, Caller ID so on and so forth using SBSetting.

It is quite annoying when you called someone then the calls drop within 10secs. But I had no problem with incoming call. Thanks in advance.

And you're using Celcom? I don't think it is faulty iPhone because I had no problem whenever using Maxis. Haven't try DiGi though.

Anyway, I got a friend with the same problem as me, and I am using 128K 3G sim card.

I'm not really sure about this. Apparently, my Maxis Postpaid is using 128K. Suppose shouldn't be any problem or perhaps, Celcom using different way to broadcast? Will ask Celcom whether they still producing 64K sim card. *sigh*

@Edoras,

Currently I am using Celcom and Tethering is available for me. But haven't use it yet.

iPhone 3GS 3.0.1 and latest iTunes v9.0.1

I won't upgrade for the time being

I bought from Maxis. OTB firmware was 3.0.1. Straight JB without doing anything eg; those ipcc files.
I just don't know how this feature is available for Celcom

By the way, regarding my reception call drop, can I just update my FW to 3.1 from iTunes and upgrade the baseband as well? Might think that the new baseband can handle Celcom broadcast? Thanks. I don't need the tethering at the moment.

Suppose there will be no problem at all.
I'm using Celcom with 3.0.1 and I can send mms without any problem.
Now I am using 3.1 and still can send mms. The only problem is just for AT&T Carrier where they are still waiting AT&T to enable mms for 3.1 and 3.1.2 I suppose

Try to restore back. I just update mine to 3.1.2 and everything was fine.

I am using OS 3.1.2 Maxis set. Using Celcom sim card and I can send mms flawlessly. Have you set your MMS setting and restart your iphone?
By the way, may I ask whether you are using postpaid 3G sim card? I got problem with 10secs call drop

@tinkerbel
not really have to set 10secs. Whenever I call someone, right after 10secs of conversation, the line will drop. So I have to call again. Second time call no drop after that. I dunno why. Pop-in my simcard to other phone and it seems the problem doesn't happen. Might thinking that my Celcom simcard is faulty to use with iPhone.
Apparently, if I insert Maxis simcard into the iPhone, there is no problem at all.

Just now that I realize that whenever I'm at EDGE area, the call will drop. Still troubleshooting though

@NV20
You can capture the screen by pressing power button and home button at the same time. It will then stored into you DCIM folder.
Then use utility like DiskAid (Mac) to transfer to MacOsX. As for Windows utility, you can check at pinned thread there. I'm using MBP though
