Iphone 5 no service coverage(No network)

[RevStar Zen]

Has anyone here encountered the same problems with True-H on their iphone 5 even though the area i'm in have full service bars?

I've tried almost every remedies posted on apple discussion forum but none seems to work.

Seems like a software glitch and anyone here managed to overcome this?

Fustrating as in u can't use the basic of what the phone is for!

I would suggest,

Buy a cheap sim in any 7/11.

Cut it down to micro sim size.

And try your phone with this new sim, this will rule out if it's the SIM or the Phone

One simple thing to try is turn it off, wait 1 minute then turn it back on.

Is this a new problem? Does it happen everywhere?

Not sure if it is an issue related to 2100 MHz, and your phone getting confused between CAT/TrueMove H (850 MHz) and the newer TrueMove H 2100 MHz 3G and/or LTE?

I have no problems with TrueMove H on an Android phone.

Reset network settings...

SIM Card would be next step to verify if you have done all troubleshooting. Try Changing new SIM at True shop, maybe this would help.

Go to your local True store and hand you iPhone to the pretty lady and say Mii Me Internet...

Reset Network Settings-Checked.

SIM card changed-Checked.

Restore as a new iphone 5-Checked.

The phone just won't lock onto True's network although tried on another android and another iphone 5,it works.

Still it's still under warranty,will bring it down for a check by Apple Store back in Singapore as it's a SG set.

However,i have this inclination that the phone is confused due to recent upgrade of True Move's 2100 latest bandwith which they market it as 4G?

SingTel in Singapore uses 900/1800/2100(3G)/2600(4G-LTE) which i'm afraid if i try a SingTel sim card in,it'll work?

Hmm...if tat's e case,must i switch operator to AIS instead when i wanna use the phone in thai?

If the SIM 'works' in a different iPhone 5 and another Android phone then I guess I'd compare the settings from the working iPhone 5? If those can be replicated and you still have an issue then it might an issue with the phone?

I know with my Android phone and a TrueMove H SIM I had to change the 'username' to "ture", rather than true, and the 'APN type' to "default,supl", remove the quotes.

It does look like a phone configuration issue, maybe re: 'Authentication', but I have no experience with iPhones.

Yeap,brought the phone to True Cust Service to have it's APN keyed in as well,unsucessful and was advised to bring phone back to Apple Service Centre...zzzz
