I ported my number yesterday, and it cancelled my service immediately, but now I have no service whatsoever. I tried restarting phone, removing SIM and putting it back in, turning phone off and turning it back on.
I did not miss a step in the registration process. When switching SIM cards the default network in the settings on the phone changed from 4G to 2G. I changed the default network to 3G, and it connected to the carrier immediately. I am posting this so...
