I noticed that sometimes CTCarrier.mobileNetworkCode
returns undocumented values. Examples below:
- Is VZW Verizon?
- "" (empty line) instead of nil, when the device does not have a SIM card installed or in AirPlane mode - it looks like an error.
- Is "65535" some special meaning that means something?
What do these specific undocumented codes mean?
