Old number changeover

[Grogerus]

I was sent a clear and unambiguous text to my old number that it would transfer to my new sim on my new phone by 6pm today. I turned off the phone all day as recommended (indeed I had to turn off my old phone with the old number as the battery is failing). The swap has not happened and yes I tried switching my new phone on and off. No change. This is extremely inconvenient right now and if O2 say that the changeover will happen today that is what I expect. This is urgent. Please help. My default option may be to return to my old contract with virginmedia.

Some swaps are taking longer than others.

If you have no service at all borrow a phone, use a landline or try Skype to get through to O2

This might sound silly, but can I put the old sim in my new phone and wait for the number to fail then put the new sim in?

My old phone was an HTC One M10 and my new phone is an iPhone if that is relevant.

As long as they are the same size then yes you certainly can

There's no need for any sim to be in any phone. Just leave your new sim in the new phone and it will change at some point. 
ports can happen up to 9.00pm. 
PS. If you stick with o2 long enough you'll be back on virgin anyway

Thanks for your help everyone. Yes I was aware of the mega-merger. The O2 contract is currently better. Just a bit frustrated (as we all are in the current circumstances) that the changeover seems to have become more troublesome in recent years rather than easier as you might expect with improving technologies. I'll give it 24 hours then contact O2 (if that's possible). Thanks again.
