I would like to share my experience in resolving 3G signal lost using Maxis latest carrier update 13.2

I have this irritating issue which even after network reset is also not consistent. Then, after reading few feedback in MacRumors with regards to this issue, I have decided to restore my phone via iTunes as a fresh new phone. I get all the contact back up from iCloud.

Now, it has been a week since I performed the recommendation approach and I could say it is perfect. I dont have to toggle the airplane mode or restart or hard reboot the phone anymore.

Anyone of you may want to consider this approach which perhaps working fine to solve your issues. It is not a guarantee it will 100% resolved the issue but at least it did to me.

Hope this helps.

Futhermore, I cant confirmed should it is iOS bug or Maxis as both of my iPhone 5 which are using Maxis have the same trait of issue.

I am now happy without the hassle of lost 3G connection.

Sorry. My apologies. It is supposedly 13.1 officially instead. I've performed a tweak to change the Maxis logo to be a custom logo which the carrier file is 13.2. But the customization of the logo is not related to the 3G signal lost at all.

I am on iOS 6.0.2 which I had issues with the signal lost since iOS 6.0.1

Yup. I breached the quota of 4GB and it was very torturing speed. Whatsapp, twitter still as usual only apps like FB, instagram you will feel it is very very very slow.

Go to Maxis and seek for replacement unit. I did that and get a replacement set. I went report to Maxis KLCC.
