iPhone 4s 5.1.1...cant make calls.

rightyabe

Bought a 2nd hand 4s today, put in my sim card and I was unable to make or recieve calls, but could send and recieve messages.

Then a few min ago I could recieve calls but still not make them.

Anyone know a fix? iOS 6?

I tried the set the time manually trick/show caller id etc but no joy.

Sounds like its blacklisted

rightyabe

would there be any way to unlock it if its blacklisted?

Have you reset your Network Settings?

how do you do this?

Cushie Butterfield

Settings => General => (scroll all the way down to) Reset => Reset Network Settings

may be slightly different in iOS 5 but you'll find it there or thereabouts.

woke up this morning and the phone was able to make calls, so I think i'm out of danger. however it keeps losing internet connection but I think this is down to the carrier more than anything.

Any how I went on to gumtree and there's a fella who says he can unlock my iphone for $50 (Im in Oz) I'm just wondering would this cause any problems or is it a straight forward process.

Cheers in advance.

It doesn't sound like it's blacklisted.
Was the phone jailbroken (is there an icon somewhere called Cydia)?
If not I'd say you should do a reset of everything (back up to iTunes or iCloud first!) and then update it to ios6. Actually the upgrade to ios6 will erase everything, incl settings, and make the phone like brand new again.

No sign of Cydia, and when i switch the phone on a apple logo appears and not a skull, I think that is a way to tell also (not 100%).

I've heard a few stories of iOS 6 causing problems on the 4s etc and i'm a bit weary of getting it. Should I do it before or after I unlock it.

biko

Why do you want to unlock it? If it works for calls and messages it's already unlocked.
If you can't find Cydia the device isn't jailbroken so should be fine to upgrade.

But before you do anything I suggest you reset Network settings as Cushie Butterfield said, this alone will probably fix the issue.
You can also do a hard reboot/reset (it won't delete anything)

Reset the iPhone by holding the sleep/wake button at the top right of the device and the home button at the bottom center of the face at the same time.
Hold them both until you see the screen go black. In some cases, you may need to keep holding them even after the red power off slider appears. If it does, just keep holding it.
Wait until the white Apple logo appears.
When this happens, you can let go - the iPhone is rebooting.

Do the above twice.

Sorry biko i should of explained better, i'm in Australia and the phone is locked to Optus network, this network works fine in the city but as soon as your 50km outside the city the signal goes.

I want to unlock it to use the Telstra network which has a signal in 99% of remote places, and as I work in remote Western Australia I need the Telstra network.

So will I wait until after I unlock and start using my telstra sim to reset settings?

thanks again

Ah, yes in that case you should get it unlocked.
If the guy from gumtree wants to jailbreak and unlock it that way it won't work if you also update phone, but there is no harm really in keeping it on the current 5.1.1.

If you get a real unlock from Apple you can upgrade the phone to ios6 without issue, check with Optus first if they will do it for you.
Guy here got it free

The guy told me he won't have to jail brake it, just unlock it...is that even possible?

Also if he has to JB it will I be able to update to iOS 6 in the future? And does a JB affect the phone?

biko

He will (probably) just buy an unlock code online. Can be got on ebay.
Speak to Optus, it might just be cheaper that way.

If he jailbreaks it you can still upgrade to ios6, but if you do you'll lose the jailbreak.

rightyabe

Hey got it unlocked from the fella on gum tree, took him 20mins.

Thanks for all your help.
