Apple iPhone initial setup call connection issues
So you've just got a new iPhone, (congratulations by the way) inserted the microSIM card using the little tool that came in the box and followed the on screen setup process to create or sign into your iTunes account.
Now you're ready to start enjoying your mobile, but there's just one problem - your calls won't connect. Why is this?
Well, once you've entered your setting preferences and accessed iTunes, it's your SIM card's turn to get set up.
The iPhone attempts to use the SIM card to communicate with your Mobile network, so that it can pull down the settings it needs to access network services for phone calls, texts and the internet.
If your iPhone can't connect to the mobile network, you'll see 'no service' appear in the top lefthand side of your notifications bar, like this:

This is known as a provisioning error and can be caused by one of two things.
- Your network has not ‘switched on’ (provisioned/activated) your Sim card yet, so it is not live on the chosen network – This can take between 24 and 48 hours, so sit tight for a while.
- You are porting your old number to a new micro SIM, which can take your network operator up to 72 hours to complete.
If you're still waiting for network access after 48 hours, give your network operator a call to make sure they have received the correct information.
Some network operators allow you to activate your own SIM via their website, so there's no need to wait or call. If you are with o2 you can register your SIM at http://swapmysim.o2.co.uk/ in a few easy steps.
If you're not sure what’s wrong but your iPhone says 'no service' in the notifications bar, and you've waited 48 hours since first inserting the SIM card, the best thing to do is to give your network operator a quick call.
