IMessage and FaceTime are waiting activation for two days

Question

Hi, two days ago I changed my ‘self-cut’ sim-card to nano-sim art my carrier office.
For 20 days before that iMessage and Facetime worked perfectly fine with two different carriers, they activated normally.
But after the moment I put new sim-card into iPhone it just quit working. It's always ‘waiting for activation’ on my phone number (works normally with e-mails though).
It's mostly iMessage I'm worried about.
I've tried:
1. Turn off iMessage, reset network settings, turn off the phone, turn on the phone, turn on iMessage;
2. Turn off iMessage, check that ‘My Info’ in Mail, Contacts and Calendars is correct, turn on iMessage;
3. Reset to the factory settings, after that — I've tried to activate it on ‘clear’ device, same result, so I recovered all my info from the backup.
4. Went to my carrier office, changed three sim-cards (1 — nano-sim, 2 — micro-sim, which I cut, 3 — nano-sim again), no result.
5. Put my latest sim-card into other iPhone 5 — no activation in 5 minutes.
6. Put another sim-card of this carrier into my iPhone — no activation in 5 minutes.
I'm already desperate here, my carrier says ‘you have to ask Apple Support’, Apple Support is on answermachine that says ‘ask your carrier’, I just need my iMessage working normally

Hello, I can understand how frustrating this is.
I spoke to Apple just now, and they're aware. There's no solution, except to wait it out. Because of the 5s launch and iOS 7, Apple's servers are supposedly being hammered. A more senior Apple rep thought there will be delay up to 48 hours.
I have a 5s, and so does my friend. We both have the same issue as you.
