How long to activate new phone & SIM after calling customer service?

[highwire]

I called customer service to transfer my service from my old iPhone and Sim to my new iPhone 5 and nan-SIM.  After about an hour, my new phone still says "No Service". 

How long does it normally take?  Cheers....

Hi highwire,

There are currently longer delays for activations. Please try powering your phone off and back on. It can take up to 4 hours unfortunately.

We apologize for the delays.
