Don't worry.. Its not your ip5, it caused by Celcom line..

Maxis is currently undergoing tests by Apple for their LTE network support and if they passed everything, Apple will release software update to enable i5's LTE setting. I also feel that my 3G improved. Places where most phone only getting EDGE networks, this guy still can get 1 bar of 3G. And usually after entering places with no service, have to reboot phone to get Internet but now I got 3G straight away. But when turn on data still stuck at EDGE for a while......

I think maxis have problem because i just came back from vietnam. when use vietnam sim card, i can receive 3g signal flawlessly. when change back to maxis either stuck on edge or gprs

I received this msg as well.. Ive got to admit.. Now 3G is slightly improve.. But EDGE sometimes ok and sometimes not.. 3G is working tho...

I also experiance the 3G bug right after the update...

I received this from Maxis..

I received tht too

So... Is the Celcom problem or the iphone5?

My 3G can stuck for awhile only.. Always back to edge. But using the same phone in Taiwan and Singapore there is no such problem.

Should report to Celcom? Cos no point report to apple... They are useless junk working there.

same case as mine

Anyone does have issue with Maxis data signal recently that if you are out of 3G or Edge connection (no network on mobile or data) and then reenter into location has coverage (mobile or data), you can't get back data connection (either edge or 3G)?

What you have to do is, off the phone and switch on again to get back data signal?

I also encountered such issue. But normally after restart, the phone will be able to connect to 3g signal. BTW, I am also maxis user. Hope expert to advise. TQ

telco problem call them to solve

Hi bro, just to share...
Ive got the same problem as yourself...but manage to sort it out without having to restart...

ANSWER;
You need to set carrier setting as "manual" and choose "MAXIS"....

Thats it ! it settles the issue...

I was having so much trouble with it...imagine that i need to restart the phone everytime i come out from the lift....gila !

Thanks for sharing.

I filed complaint to Maxis and they checked and mentioned no network issue.

Second time, walked to Maxis center and showed them the issue. Few days later they feedback is iPhone 5 issue and they will feedback to iPhone for bug fix

I don't think this issue is due iOS issue. I was with uMobile 2 weeks ago and I didn't have this issue. 100% is maxis issue but they blamed iOS.

Hi millincoll.

Thanks so much for your sharing.
Quick question. Do you still encounter such issue, now?

Thanks for your response.

yup...never had any issue since then.... enjoy ur iphone !

Having this same issue too!! will try this method... feedback if it's solved

Have you manage to get this to work? I recently encounter this problem. 3G can't reconnect after a network loss/refresh.

I'm on DiGi.

this seems not working for me.

Got mine working now. Done ^ that and also went to the shop to change a new Nano SIM.

So far so good this few days, no 3G drop yet. (DiGi)

just to update guys that with ios 7 and its latest update for 7.03. i did not have to resort to this manual "setting"....

it has been on automatic and its all fine all this while since the software's introduction.

case closed.
