[AC Question]

when I dial a number, it says mobile network not available

you might have not put in the correct number ex: [phone number redacted by Mod] "that's a fake number" or maybe it has something to do with your network. try and talk to your carrier.

Welcome to Android Central! Does this happen with any number? Do you have a valid plan set up with your carrier, and a valid SIM card inserted?

FYI, I redacted the "fake" phone number you gave as an example, because 808 is a real area code (Hawaii), and even though it may not be a real number now, at some point it might become a real number. Better to use the ol' Hollywood convention of "555-nnnn."
