So I recently picked up an iPhone 6+ and took out an O2 Sim only deal, switched from T-Mobile and gave O2 my PAC code on 19th. The iPhone was working fine (with new number) and yesterday both phones lost network connectivity. I was thinking good, this is the number being transferred but all day yesterday no signal. I visited the O2 shop and the guy said all looked fine and to keep switching the iPhone off/on, have been doing that but today and still no network on either phone. I'm now starting to worry I have lost my number 
Any ideas on what maybe the issue or what I can try to get the phone up and running as living of wifi is impossible. I have reset the network settings, taken out and re-inserted the sim. Have tried manually adding my number to the phones settings and still no luck.
Cheers!
