Vodafone unlocked but no O2 signal

Hi all,

 

OK... have put my existing (working) PAYG O2 SIM card in my nos (sealed box) Vodafone iPhone 4s and successfully unlocked it via iTunes (Congratulations, your iPhone has been unlocked), waited a couple of hours only to find I've NO signal (phone is showing: ooooo O2-UK), 3G (internet) and everything else is working fine but unable to send or receive calls, messages etc. Have tried every conceivable reset and restore and If you can't make or receive calls on your iPhone - Apple Support ...all to no avail !

 

Anyone know how to resolve this ?

Sounds like the handset is barred.
Where did you get it from?

It's worth checking your IMEI number on here https://www.checkmend.com/uk/

If my phone has been barred, is there any way to get in unbarred ?

Only if it was you who requested it to be barred because you lost it and then found it again.
They are usually stolen handsets that have been barred by insurance companies because they have paid out a claim for them. These then get peddled on ebay to unsuspecting customers or sold off in pubs etc.

This is the latest...

 

Yesterday, Vodafone confirmed my phone was NOT blocked.

 

Received new email from Vodafone this morning.

 

They unlocked the phone again at their end and asked me to unlock via iTunes with a new update (9.3.2). This was again successful and this time I HAD signal... that was until the point of confirming my Apple ID password during the set up as a New Phone, when it disappeared again.

 

As per Vodafone instructions, I did another iTunes restore, which this time asked me to turn 'off' Find iPhone (app), which I did.

 

I've since removed 'My Device' from iTunes also and done yet another restore but still have NO signal...

So the iPhone did unlock and you got o2 showing as the carrier?

 

The next thing to check would be for local o2 issues http://status.o2.co.uk

 

When you unlocked via iTunes did it say something along the lines of iPhone unlocked ? (Forget exact wording as done all mine ota recently)

Maybe sim is faulty?
