iPhone Test Field Mode, Serving PLMN Info and Cell ID.

I'm working on a project and needed to validate the Location Area Code and Cell ID in my tests with actual info from my mobile phone. Using an iPhone and going into Test Field Mode did the trick.

Go into Test Field Mode:

  • Dial *3001#12345#*
  • MM Info -> Serving PLMN - Gives you MCC, MNC, RAC and LAC
  • UMTS Cell Environment -> UMTS RR Info - Gives you Cell ID
There's much more information there and it's very handy since you don't need to muck about in an app.
